With email communication playing a critical role in the customer engagement strategies of virtually every organization, high email deliverability rates are vital to success across all industries. In the healthcare sector, however, the stakes can be far higher. An undelivered email isn’t merely an inconvenience or a lost sales opportunity; it could mean a missed appointment, a delay in a prescription refill, or a failure to get a patient critical healthcare information. Or worse, the email could end up in the hands of an unintended recipient, including bad actors and cybercriminals.
With this in mind, this post details why high email deliverability is essential for healthcare companies, as well as how your organization benefits from reliable and rapid email delivery.
Speed and Efficiency
The primary reason that high email deliverability is crucially important to healthcare organizations is to best guarantee essential communications that directly impact an individual’s healthcare journey reach them promptly. These transactional emails can include appointment reminders, prescription renewals, product order confirmations, test results, explanation of benefits notices, payment reminders, and invoices. Administrative notifications related to software or systems that a patient might use, such as a password reset for an online portal, also fall under the category of transactional emails.
When transactional emails are delayed or fail to reach people altogether, they can compromise a patient’s ability to access care, adhere to treatment plans, stay informed on key facets of their healthcare journey, and, ultimately, achieve optimal health outcomes.
When a patient fails to receive an expected email, such as a prescription confirmation, for example, it can leave them feeling confused and unsure of what to do next. For individuals who are sick, elderly, or managing chronic conditions, this can cause unnecessary stress, anxiety, and even compromise adherence to care plans.
In contrast, high email delivery rates create the opposite effect, helping patients get the communications and information they need. This increases their trust in your company and gives them a firmer sense of control over their healthcare journey.
Compliance with HIPAA Regulations
While the above point stresses the importance of reliable email delivery for the patient’s and customer’s benefit, healthcare companies also have a vested interest in ensuring communications reach the intended recipient for regulatory and patient privacy reasons.
To comply with the Health Insurance Portability and Accountability Act (HIPAA), emails that contain sensitive patient data, i.e., electronic protected health information (ePHI), must be securely delivered to the intended recipient. If, on the other hand, a communication containing ePHI fails to reach the intended recipient patient, that represents a failure in secure communications and a potential HIPAA violation for your organization.
After all, where did the patient’s data go? Was it delivered to the wrong person? Was it blocked by a spam filter and is left sitting unencrypted on a server somewhere?
If you can’t answer these questions, you could be exposed to a data breach, and it could result in a HIPAA violation, meaning your organization incurrs the associated consequences, including financial penalties and reputational damage. Conversely, deploying a fully HIPAA compliant email solution, such as LuxSci, supported by a dedicated infrastructure and designed for high email delivery enables your organization to include patient data in communications with confidence and ensure you messages land in the recipient’s inbox.
Greater Levels of Personalization and Engagement
Finally, high email deliverability rates are essential for healthcare organizations because they help drive greater levels of engagement with patients and customers. Higher email deliverability means better inbox placement, leading to more emails being opened, more links being clicked, and more conversions for your communications and campaigns.
In the case of healthcare retailers, for example, this equates to converting more prospects into customers and, consequently, maximizing the ROI of email marketing campaigns, in some cases with up to 80% better results.
While healthcare marketers, understandably, focus most of their efforts on crafting attention-grabbing headlines, personalizing the message content, and the email’s design elements, these factors are rendered irrelevant if the message fails to reach the recipient in the first place! When you take this into account, high email deliverability is a crucial component in optimizing the ROI of email communications and campaigns, and an all too often overlooked component at that.

Most conversations about HIPAA compliant email eventually land on the same acronym: TLS. It’s the most common encryption method in use, and for good reason — it’s widely supported and relatively simple to enforce. But TLS isn’t the only encryption standard healthcare organizations should understand, and it isn’t always the right tool for securing your email address and message content.
S/MIME is the other name that comes up frequently, especially in healthcare, and usually in the same breath as PGP, along with some confusion about what it actually does differently. This guide breaks down what S/MIME is, how MIME works underneath it, how to configure it, and — just as importantly — when it’s genuinely worth the effort versus when it isn’t, based on both the technical standard and real feedback from the people who’ve actually had to manage it.
If you haven’t yet worked through the basics of what makes email HIPAA compliant in the first place, our HIPAA Compliant Email guide is a useful starting point before diving into a specific encryption standard like this one.
What Is S/MIME?
S/MIME stands for Secure Multipurpose Internet Mail Extensions (also written Secure/Multipurpose Internet Mail Extensions). It’s a security extension of MIME, the original standard introduced in 1992 that first allowed email to carry more than plain text — attachments, formatting, and different character sets. Understanding how MIME works helps explain what S/MIME adds on top: where MIME made richer content possible, S/MIME made that content secure by encrypting it and digitally signing it.
S/MIME’s roots as a security standard go back to the early 2000s, largely through work done by RSA Security, one of the earliest companies focused on computer and network security. Because it’s been around for so long, S/MIME is supported natively by most major email clients, including Outlook and Apple Mail, without requiring third-party software or plugins.
At its core, S/MIME provides three distinct protections for email security:
Encryption — ensures that only the intended recipient, using their private key, can read the email messages sent to them
Sender authentication — verifies the identity of the sender, so the recipient can trust the email actually came from who it claims to be from
Digital signing — confirms the message wasn’t altered in transit, effectively letting you digitally sign each message you send
This combination is what distinguishes S/MIME from encryption methods that only protect the connection a message travels over. S/MIME protects the message itself — a meaningful distinction for any organization handling sensitive data security requirements.
How Does S/MIME Work?
S/MIME is built on Public Key Infrastructure (PKI) and asymmetric encryption — a system that uses two mathematically linked digital certificates instead of one shared password.
Public key — shared openly, used by others to encrypt messages sent to you and to verify your digital signature
Private key — kept secret and secure, used by you to decrypt received messages and sign outgoing ones
When someone sends you an S/MIME-encrypted email, they encrypt it using your public key. Only your corresponding private key can decrypt it, meaning that even if the message is intercepted somewhere along its path, it remains unreadable without that specific private key. This is what people mean when they describe S/MIME as end-to-end encryption: the protection travels with the message itself, not just the connection carrying it.
To configure S/MIME, both the sender and recipient need:
A digital certificate, issued by a trusted certificate authority (CA), tied to their specific email address
That certificate properly installed and configured in their email client
Each other’s public key, exchanged in advance, so encryption and decryption can actually happen
If any one of these pieces is missing on either side, S/MIME simply doesn’t work for that exchange — a limitation that comes up constantly in practitioner discussions, and one worth understanding before you invest time configuring it.
What IT Practitioners Actually Say About This
One useful, if slightly humbling, reality check comes up repeatedly in IT forums when people ask whether they should bother configuring S/MIME: as one systems administrator put it plainly, most people you correspond with have no idea how to verify a digital signature and won’t even notice if one is missing. Emails from your bank or a government tax agency, they pointed out, typically aren’t S/MIME signed at all — a sign of just how limited real-world verification behavior actually is outside of specific technical or regulatory contexts.
Another common thread: several IT professionals candidly noted that email clients like Outlook can create friction by automatically trying to reply with an S/MIME signed message, which can be genuinely annoying for a recipient who has no certificate configured and no way to make sense of the added complexity. Their advice, consistently, boiled down to one clarifying question: it isn’t a question of whether you should configure S/MIME, but whether you actually need it — if none of the people you communicate with require signed email, the added configuration probably isn’t buying you anything meaningful.
That distinction — need versus want — is exactly the lens healthcare organizations should apply too, and it’s the framing this guide uses throughout.
S/MIME vs. TLS vs. PGP: How They’re Different
It’s easy to lump every encryption acronym together, but each one solves a slightly different problem.
Method
What It Protects
Identity Verified Via
Complexity
TLS
The connection between mail servers
Server-level certificates, not individual senders
Low — largely automatic, minimal user setup
S/MIME
The message content itself, end-to-end
Trusted certification authorities issue and vouch for individual certificates
High — requires certificates and key exchange for every sender/recipient pair
PGP
The message content itself, end-to-end
A decentralized “web of trust” — users vouch for each other directly
High — similar certificate/key management burden as S/MIME
TLS encryption – most people interact without realizing it — it’s what protects the connection when your email travels from your server to the recipient’s server. The tradeoff is that TLS only protects the message in transit; once it lands on a mail server, TLS’s job is done.
S/MIME and PGP both aim to close that gap by encrypting email messages themselves, so they remain protected even after delivery. The key difference, as one privacy-focused forum discussion put it well, comes down to how identity is managed: S/MIME farms identity verification out to a trusted certification authority, while PGP requires you to manage that trust relationship yourself. For most healthcare organizations, S/MIME’s centralized CA model is the more practical fit, since it aligns better with how enterprise IT departments already manage digital certificates and existing vendor relationships.
Key Benefits of S/MIME
Genuine end-to-end protection. Because the message itself is encrypted, S/MIME protects data security even if it passes through servers that don’t support encryption.
Built-in sender authentication and message integrity. Digital signatures verify both the identity of the sender and that the message hasn’t been tampered with — a layer TLS alone doesn’t provide.
Broad native support across email clients. Most major email clients support S/MIME out of the box, without requiring a separate plugin.
Flexibility to sign without encrypting. As one practitioner pointed out, you can digitally sign an outgoing message without encrypting it — useful for something like a mailing list, where you want recipients to trust the message came from you, but full encryption isn’t necessary or practical for a broad distribution list.
The Real Tradeoffs of S/MIME
Certificate management is ongoing, not one-time. Every sender and recipient needs a certificate tied to their email address, renewed and reissued as staff change roles or leave. Manageable for a small group; significant admin overhead for a whole organization.
Both parties must be configured correctly. If a recipient lacks a certificate or the sender’s public key, the message bounces or fails to send encrypted — some systems fall back to TLS, but only if configured to do so.
Most recipients can’t verify it anyway. IT practitioners consistently note that outside specific business or regulatory contexts, recipients have no practical way to check a digital signature — and default behaviors like auto-signed replies can just create friction.
It doesn’t scale to high-volume email. S/MIME suits direct correspondence between known parties, not appointment reminders, billing notices, or large mailing lists.
It can conflict with malware scanning. End-to-end encryption blocks gateway-level inspection, so scanning has to happen at the endpoint instead.
How to Configure S/MIME?
For Individuals
Obtain an S/MIME certificate from a trusted certificate authority. Certificates come in different validation levels — Basic (validates only the email address), Individual Validation (confirms personal identity), Organization Validation (confirms the business’s legitimacy), or Sponsor validation (combining both).
Install the certificate in your email client — most major email clients, including Outlook and Apple Mail, support this natively.
Configure the client to use the certificate for both encrypting outgoing messages and verifying signatures on incoming ones.
Exchange public keys with anyone you intend to correspond with securely — typically by sending them a signed (but not necessarily encrypted) email first, which shares your public key automatically.
For Organizations
Determine the validation level your organization actually needs. Higher validation levels provide stronger identity assurance but involve more verification steps and cost.
Use centralized tools to manage the certificate lifecycle. Protocols like LDAP or endpoint management platforms (such as Microsoft Intune) can significantly reduce the manual burden of distributing and renewing digital certificates at scale.
Distribute certificates and provide clear installation guidance to every employee who needs S/MIME — this is often where organizations underestimate the support burden, particularly for less technical staff.
Set clear policies on when S/MIME is required versus when other encryption methods, like enforced TLS, are sufficient. Treating S/MIME as a blanket requirement across an entire organization typically creates more friction than protection, echoing exactly what practitioners report when they configure it without a clear need.
When Does S/MIME Actually Make Sense?
Given its administrative overhead — and the recurring, practical feedback from people who’ve actually configured it — S/MIME is best reserved for specific, high-sensitivity use cases rather than applied indiscriminately:
Clinician-to-clinician communication involving particularly sensitive diagnoses or treatment details, where both parties are known and willing to maintain certificates
Cross-organization referrals where a small, defined group of specialists regularly exchanges detailed patient information and can reasonably manage the certificate relationship
Legal, compliance, or executive correspondence where verifying the sender’s identity and confirming message integrity outweighs the setup cost
For everything else — appointment reminders, billing communications, marketing outreach, or high-volume patient correspondence — enforced TLS or a managed encryption platform that automatically selects the right method per recipient is almost always the more practical choice. This mirrors exactly what experienced IT practitioners consistently conclude on their own: it’s not about whether S/MIME can work, it’s about whether your specific communication actually needs it.
A Simpler Path: Automated, Per-Recipient Encryption
The tradeoff most organizations run into with S/MIME isn’t whether it works — it’s whether staff can reliably manage digital certificates for every relevant contact without errors slipping through, and without creating the kind of recipient friction practitioners describe so consistently.
Rather than requiring every sender and recipient to individually configure S/MIME, some HIPAA compliant email platforms automatically select the appropriate encryption method per recipient — TLS when it’s sufficient, a secure portal when the recipient’s system doesn’t support TLS, and PGP or S/MIME when the situation calls for genuine end-to-end protection and sender verification. This removes the burden of manually deciding — and manually maintaining certificates — from individual staff members, while still making S/MIME available for the specific cases where it’s the right tool.
What Should I Do Now? (revised with target-keyword anchor text)
S/MIME is a legitimate, well-established way to secure your email and verify the sender — but understanding when to use it, and when a simpler method is more appropriate, matters just as much as knowing how to configure it. Most healthcare organizations don’t need S/MIME everywhere; they need the right encryption method applied automatically, based on the situation.

FAQs
1. Is S/MIME better than TLS for email security?
Neither is universally better — they solve different problems. TLS protects the connection a message travels over and suits high-volume, everyday email. S/MIME protects the message content itself, end-to-end, and suits specific, high-sensitivity communications between known parties who can manage digital certificates.
2. What happens if I send an S/MIME encrypted email to someone who doesn’t support it?
The message typically won’t deliver as encrypted, and depending on how the sending system is configured, it may bounce back to the sender or automatically fall back to TLS.
3. Do I need a separate digital certificate for every email address, or just one for my organization?
Each individual email address needs its own certificate issued by a certificate authority. A single organizational certificate doesn’t cover every employee — certificates are tied to specific addresses, not the organization as a whole.
4. Can I digitally sign an email without encrypting it?
Yes. Signing confirms the identity of the sender and that the message wasn’t altered, without requiring the recipient to have a certificate of their own. This is useful for situations like mailing lists, where full encryption isn’t practical but sender verification still adds value.
5. Is S/MIME a good fit for HIPAA compliant marketing emails?
Generally, no. S/MIME’s certificate and key exchange requirements don’t scale well to high-volume or one-to-many communication like marketing campaigns. Enforced TLS or a platform that manages encryption automatically per recipient is typically the better fit for that use case.
Few terms in healthcare get thrown around as loosely as “HIPAA violation.” It gets invoked when a nurse mentions a patient’s diagnosis to a friend outside of work, when a technician talks about a well-known patient who came through the clinic, or when a physician casually brings up a person’s rare diagnosos at a backyard barbecue — situations that sound like violations but often have nothing to do with the actual law. That confusion isn’t just an oversight, but rather, it points to a gap in understanding what HIPAA covers, who it applies to, and what genuinely puts an organization at risk.
For health care providers, compliance officers and IT professionals, the stakes behind that confusion are anything but casual. The Department of Health and Human Services (HHS) Office for Civil Rights (OCR) has issued settlements ranging from a few thousand dollars to over $16 million for the same underlying failures, such as a missed risk assessment, an unencrypted laptop, a chart accessed by the wrong person. This guide breaks down what actually constitutes a HIPAA violation, the most common ways organizations end up on OCR’s radar, what genuinely falls outside HIPAA’s scope, and what to do if you’re managing risk or responding to an incident right now.
If your organization handles PHI over email — one of the highest-risk channels for exactly this kind of violation — our HIPAA Compliant Email guide is a useful next read once you’ve worked through this one.
What Is a HIPAA Violation?
A HIPAA violation occurs when a covered entity, business associate, or a member of either’s workforce fails to comply with a standard set out in the HIPAA Privacy Rule, Security Rule, or Breach Notification Rule — or fails to follow an internal policy implemented to support HIPAA compliance.
That definition matters because it draws a hard boundary around who can actually commit one. HIPAA applies to:
Covered entities — healthcare providers, health plans, healthcare suppliers, payers, and healthcare clearinghouses
Business associates — vendors and contractors that create, receive, maintain, or transmit protected health information (PHI) on a covered entity’s behalf
Workforce members — employees, volunteers, and contractors of either of the above
HIPAA does not apply to private individuals acting outside of a covered role — a distinction that trips up far more people than you’d expect, and one we’ll come back to later in this guide.
The Health Insurance Portability and Accountability Act (HIPAA) was designed to protect the confidentiality of medical records and patient data while still allowing healthcare organizations to function and share information when appropriate. A violation happens when that balance breaks down — when PHI is accessed, used, or disclosed in a way the law doesn’t permit, or when required safeguards simply aren’t in place.
The Three HIPAA Rules a Violation Can Break
Every HIPAA violation traces back to one (or more) of three core rules. Understanding which rule is in play helps clarify what actually went wrong — and what needs to be fixed.
Rule
What It Governs
Example Violation
Privacy Rule
Who can access, use, and disclose PHI, and under what circumstances
Sharing a patient’s diagnosis with someone outside their care team without authorization
Security Rule
Administrative, physical, and technical safeguards for electronic PHI (ePHI)
Failing to encrypt emails in transit or a laptop that stores patient information
Breach Notification Rule
Requirements for notifying affected individuals and HHS after a breach of unsecured PHI
Missing the 60-day deadline to notify patients after a data breach
Most real-world violations involve more than one rule at once, such as a stolen, unencrypted laptop is a Security Rule failure that can also trigger Breach Notification Rule obligations. Keeping the three rules distinct in your own documentation, though, makes it much easier to identify exactly where a gap exists.
Most Common Types of HIPAA Violations
These are the violation categories that show up most often in OCR settlements, and the ones every provider, payer, and supplier organization should actively guard against.
Unauthorized Access / Snooping
This is the violation most people have actually heard about, usually because of a celebrity or high-profile patient case that made headlines. A staff member accesses a patient’s medical record without a legitimate, job-related reason — often out of curiosity, not malice — and it still counts as a serious violation.
What’s easy to miss here: the violation is about the access itself, not just what happens to the information afterward. Looking at a chart you have no clinical reason to view is a violation the moment it happens, even if you never repeat, share, or act on what you saw. Hospitals take this seriously enough to flag high-profile patient charts automatically and audit access in real time — which is exactly why staff who snoop tend to get caught quickly, and why termination is the near-universal outcome when they do.
A useful way to think about it: the sensitivity of the underlying information isn’t what determines whether accessing it was a violation — the authorization to access it through that specific system is and if a job role requires it. Pulling PHI through a restricted system without a legitimate reason is a violation even in cases where the same information might, in theory, be available through some other, non-restricted channel. Improper access through the wrong door is still improper access.
Example: Dr. Huping Zhou was sentenced to four months in federal prison after accessing celebrity medical records 323 times with no legitimate reason. UCLA Health System was separately fined $865,000 related to similar unauthorized access incidents.
Failure to Conduct a Risk Analysis
The Security Rule requires covered entities and business associates to conduct an organization-wide risk analysis identifying vulnerabilities to the confidentiality, integrity, and availability of ePHI. Skipping this step — or doing a superficial version of it — is one of the single most commonly cited failures in OCR settlements, because it’s foundational: nearly every other safeguard depends on knowing where your actual risks are.
Example: Premera Blue Cross paid $6,850,000, and Excellus Health Plan paid $5,100,000, both tied in part to failures to conduct adequate risk analyses before major breaches occurred.
Insufficient Access Controls
Access controls determine who can view or modify ePHI, and they need to be granular enough that staff can only access the minimum information necessary for their role. When access controls are too loose, such as shared logins, no role-based restrictions, no automatic logoff, organizations lose the ability to actually enforce the “minimum necessary” standard HIPAA requires.
Example: Anthem Inc. paid $16,000,000, the largest HIPAA settlement to date, following a breach connected in part to access control failures affecting nearly 79 million individuals.
Failure to Encrypt ePHI on Portable Devices
Laptops, phones, and USB drives leave the building. When they’re lost or stolen without encryption, an isolated incident becomes a reportable breach — because unencrypted PHI on a missing device is, by definition, unsecured PHI.
Example: Children’s Medical Center of Dallas paid $3.2 million after multiple incidents involving lost, unencrypted mobile devices containing ePHI.
Missing or Incomplete Business Associate Agreements
Any vendor that creates, receives, maintains, or transmits PHI on a covered entity’s behalf — from a billing company to an email provider — is a business associate under HIPAA, and business associates are legally required to sign a Business Associate Agreement (BAA) before handling that data. Skipping this step, or using a vendor without one, is a violation regardless of whether anything actually goes wrong with the data itself.
Example: North Memorial Health Care of Minnesota paid $1.55 million after failing to enter into a BAA with a business associate that later experienced a breach.
Impermissible Disclosures of PHI
This category covers PHI shared with someone who wasn’t authorized to receive it — a press release naming a patient, a social media post, filming patients without consent, or telling family or coworkers more than they’re entitled to know.
Example: New York Presbyterian Hospital paid $2,200,000 after filming patients for a documentary without proper consent.
Improper Disposal of PHI
Paper records tossed in regular trash instead of being shredded, or old hard drives discarded without being wiped, both count as impermissible disclosures — PHI doesn’t stop being protected just because someone’s done using it.
Example: Parkview Health paid $800,000 after leaving patient medical records unattended in a driveway during a records transfer.
Exceeding Breach Notification Deadlines
Once a breach of unsecured PHI is discovered, the Breach Notification Rule sets a hard 60-day deadline to notify affected individuals (and HHS, for breaches involving 500+ records). Missing that window turns a bad situation into a compounding one.
Example: Presence Health paid $475,000 for failing to notify affected individuals within the required timeframe following a breach.
Denying Patient Access to Records
Patients have a right to access their own medical records, generally within 30 days of a request, without excessive fees or unreasonable barriers. Denying or delaying that access is one of the more consistently enforced violation categories in recent years.
Example: Cignet Health of Prince George’s County paid $4,300,000 for denying 41 patients access to their own medical records.
Every one of these categories comes back to the same underlying question: does your organization actually have documented, enforced processes for who can touch PHI, how it’s protected, and what happens when something goes wrong? If email is part of that picture — and for nearly every healthcare organization, it is — our HIPAA Compliance Checklist walks through exactly what needs to be in place.
What Is Not a HIPAA Violation (Common Misconceptions)
HIPAA gets invoked constantly in situations it has nothing to do with — and clearing up that confusion matters, because it helps healthcare professionals, IT and compliance teams focus their actual attention where it belongs.
A family member discussing your health isn’t a HIPAA violation. HIPAA governs covered entities, business associates, and their workforces — not private individuals speaking in a personal capacity. Your mother telling a relative about your diagnosis might be a breach of your trust, but it’s not a HIPAA violation, because she isn’t bound by HIPAA in the first place.
Confusing HIPAA with FERPA or the ADA is common, and usually incorrect. Educational records fall under FERPA (the Family Educational Rights and Privacy Act), not HIPAA — a teacher discussing a student’s grades or attendance isn’t a HIPAA issue. Similarly, questions about a disability accommodation, like a mask exemption or a service animal, generally fall under the Americans with Disabilities Act (ADA), not HIPAA.
Asking about someone’s health isn’t the same as disclosing it. HIPAA restricts what covered entities and their workforces can disclose, it doesn’t restrict what any individual, including a coworker, cashier, or stranger, can ask. Someone asking why you’re wearing a mask or requesting proof of a medical condition might be inappropriate or even illegal under a different law, but it isn’t itself a HIPAA violation.
Vague references aren’t the same as identifiable disclosures. HIPAA violations require that protected health information (PHI) be tied to an identifiable individual. Referring to “a patient” or “a young adult male” in casual conversation is too vague to trigger a violation. Naming a specific person — “my patient, Mike, who lives on Oak Street” — alongside health information crosses that line.
A simple way to keep the distinction clear:
A nurse telling friends a specific patient’s name, date of birth, and diagnosis → HIPAA violation.
A pharmacist telling a customer their prescription refill is delayed → not a HIPAA violation.
The line isn’t about whether something feels private. It’s about whether protected health information tied to an identifiable person was disclosed by someone bound by HIPAA in the first place.
HIPAA Violation Penalties: The 4-Tier Structure
OCR calculates civil penalties based on the violator’s level of culpability, not just the severity of the incident. Understanding which tier applies matters, because the same underlying mistake can result in wildly different consequences depending on whether it was a one-off oversight or a known, ignored risk.
Tier
Culpability Level
Fine Range (Per Violation)
Annual Cap
Example Scenario
Tier 1
No Knowledge
$100 – $50,000
$25,000
The organization could not have reasonably known about the violation
Tier 2
Reasonable Cause
$1,000 – $50,000
$100,000
The organization should have known, but the violation wasn’t due to willful neglect
Tier 3
Willful Neglect (Corrected)
$10,000 – $50,000
$250,000
Willful neglect occurred, but the issue was corrected within 30 days
Tier 4
Willful Neglect (Not Corrected)
$50,000 (fixed)
$1.5 million+
Willful neglect occurred and was not corrected in time
Penalty amounts are periodically adjusted for inflation, and current maximum penalties can exceed $2 million annually per violation category — figures worth confirming against HHS’s current published rates before citing specific numbers internally.
Criminal penalties sit outside this civil tier structure entirely. Knowing or willful violations can result in criminal fines ranging from $50,000 to $250,000, plus up to 10 years in prison for the most serious offenses — typically reserved for cases involving intent to sell, transfer, or use PHI for personal gain or malicious harm.
How Are HIPAA Violations Discovered?
Violations don’t usually surface because someone confesses. They’re found through a handful of consistent channels:
Audit logs and automated access-flagging. Most modern EHR systems automatically flag unusual access patterns — a chart accessed by someone outside the care team, or a spike in access to a high-profile patient’s record. This is precisely how most unauthorized-access violations come to light; systems are built to catch exactly this pattern.
Patient complaints. Patients can, and do, file complaints directly with HHS when they believe their information was mishandled.
Breach self-reporting. Covered entities and business associates are required to self-report breaches meeting certain thresholds.
OCR compliance audits. HHS periodically conducts proactive audits of covered entities and business associates, independent of any specific complaint or breach.
One nuance worth understanding: not every violation escalates the same way. A single, isolated mistake, such as an email sent to the wrong recipient or a chart accidentally opened, is often handled through internal correction and documentation. A repeated pattern of the same behavior is a different story entirely, and is far more likely to become something an organization is required to report to HHS. This is one of the most important distinctions for healthcare organizations and compliance teams to build into internal escalation policies: document every incident, but treat repetition as a signal that internal correction alone is no longer sufficient.
How to Report a HIPAA Violation
If you’re a patient, employee, or compliance officer who has identified a potential violation, there are two established paths ti report a violation, and they aren’t mutually exclusive.
Step 1: Report it to the employer or covered entity directly. Most healthcare organizations have an internal compliance officer or reporting process specifically for this purpose. Internal reporting is often the fastest way to get a genuine mistake corrected before it escalates.
Step 2: File a complaint with HHS’s Office for Civil Rights. If internal reporting isn’t appropriate, isn’t effective, or the violation is serious enough to warrant it, complaints can be filed directly through HHS’s official complaint portal. Complaints generally must be filed within 180 days of when the violation was discovered, though extensions are sometimes granted for good cause.
A few practical notes:
Anonymous reporting is possible, but limited. OCR accepts anonymous complaints, but the lack of contact information can restrict how thoroughly they’re able to investigate.
Retaliation against someone who reports in good faith is itself prohibited under HIPAA.
Not every complaint results in a formal investigation — OCR reviews each complaint to determine whether it falls within HIPAA’s scope before proceeding.
How to Avoid HIPAA Violations & Fines
For Organizations
Conduct — and document — a genuine risk assessment. This isn’t a one-time checkbox; risk assessments should be revisited whenever systems, vendors, or workflows change.
Sign a BAA with every vendor that touches PHI, including email, billing, and IT service providers — no exceptions.
Implement role-based access controls so staff can only access the minimum PHI necessary for their specific role.
Encrypt ePHI in transit and at rest, especially on portable devices and email, where enforced encryption remains one of the most consistently under-implemented safeguards.
Train staff regularly, not just at onboarding. A single training session at hire rarely holds up against years of evolving risk.
For Individual Staff Members
Only access patient records tied to a legitimate, job-related reason — never out of curiosity, even for patients you know personally.
Never discuss identifiable patient information outside of your care team, including with family, friends, or on social media.
Report suspected violations, including your own mistakes, immediately rather than waiting to see if anyone notices.
Treat every device and email containing PHI as if it could be lost, stolen, or misdirected tomorrow, because eventually, statistically, one will be.
Since email remains one of the highest-volume channels for exactly this kind of accidental exposure, secure, HIPPA compliant solutions, such as LuxSci’s SecureLine encryption technology, are built specifically to remove the guesswork — enforcing encryption automatically rather than relying on staff to remember to apply it correctly every time.
HIPAA vs. State Privacy Laws
HIPAA sets a federal floor, not a ceiling. States are free to enact privacy laws that are stricter than HIPAA, and when they do, the stricter standard generally governs. This matters for multi-state healthcare organizations especially, such as a provider, payer, or supplier operating across state lines may need to comply with HIPAA everywhere, plus additional, more stringent requirements in specific states.
This guide focuses on federal HIPAA requirements, but compliance officers should treat HIPAA as the baseline, not the finish line, when evaluating their organization’s full regulatory exposure.
What Should I Do Now?
Understanding what counts as a HIPAA violation is the first step. Actually closing the gaps that lead to one is the harder, ongoing work — and email is one of the most common places that work quietly falls through the cracks.
Here are three ways to keep moving forward:
Read our HIPAA Compliant Email guide to understand exactly what makes an email platform compliant — and where standard email tools like Gmail and Microsoft 365 fall short.
Work through our HIPAA Compliance Checklist to audit your organization’s current safeguards against what HIPAA actually requires.
Explore LuxSci’s SecureLine encryption technology to see how enforced encryption and a signed BAA work together to close the exact gaps that show up most often in OCR settlements.
The most common violations include unauthorized access to patient records, failure to conduct a risk analysis, insufficient access controls, failure to encrypt ePHI on portable devices, missing Business Associate Agreements, impermissible disclosures of PHI, improper disposal of records, and exceeding breach notification deadlines.
2. What’s the difference between a HIPAA violation and a FERPA or ADA issue?
HIPAA governs protected health information handled by covered entities and business associates in healthcare settings. FERPA governs education records, and the ADA governs disability discrimination and accommodation. A teacher discussing grades falls under FERPA, not HIPAA. A question about a disability accommodation typically falls under the ADA, not HIPAA.
3. How do I report a HIPAA violation?
Report it directly to the employer or covered entity first, if appropriate. If that isn’t effective or the violation is serious, file a complaint with HHS’s Office for Civil Rights within 180 days of discovering the violation, using the official HHS complaint portal.
4. Can I sue someone for violating HIPAA?
No. HIPAA does not provide a private right of action, meaning individuals cannot sue directly under HIPAA. Patients can file a complaint with HHS/OCR, and in some cases may have separate legal remedies under state privacy or negligence laws.
5. Is looking up a patient’s chart without a work reason a HIPAA violation, even if I don’t share the information?
Yes. Accessing a patient’s record without a legitimate, job-related reason is a violation the moment it happens — it doesn’t require sharing, saving, or acting on the information afterward. This is one of the most consistently enforced categories, particularly for high-profile or celebrity patients whose charts are routinely audited.
In healthcare IT, the term “secure email” gets thrown around loosely. Vendors slap the label on anything with a padlock icon, and internal teams often assume that because their provider offers TLS, they’re covered. They’re not, and the gap between what’s assumed and what’s actually required is where data breaches occur and HIPAA violations happen.
This guide breaks down exactly what secure email means from a technical and regulatory standpoint, why the email platform your staff uses every day probably isn’t compliant out of the box, and what to look for when evaluating a provider that needs to protect PHI at scale. If you want the full picture of what compliance requires beyond email specifically, our HIPAA Compliance Checklist is a useful companion read.
What Is Secure Email?
Secure email refers to an email system that protects the confidentiality, integrity, and availability of message content — specifically PHI — through a combination of technical safeguards and contractual protections. It’s not a single feature. It’s a stack of controls working together.
At minimum, secure email in a healthcare context includes:
Enforced encryption in transit, so messages can’t fall back to plaintext delivery
Encryption at rest, so stored messages remain protected on the server
Authentication protocols (SPF, DKIM, DMARC) that prevent spoofing and impersonation
Access controls and audit logs that track who accessed what, and when
A signed Business Associate Agreement (BAA) with the email provider
The distinction that trips up most organizations is this: encryption is a component of secure email, not the whole picture. A provider can offer encryption and still fail to meet HIPAA requirements if that encryption isn’t enforced, if there’s no BAA in place, or if audit logging doesn’t exist. Secure email is the combination of all these pieces functioning as a system, which is why it needs to be evaluated holistically rather than checked off feature by feature.
For healthcare provider, payer, and supplier organizations, this matters because email remains one of the highest-volume channels for PHI exposure, from clinical referrals to patient billing statements to routine staff communication. Getting the definition right is the first step toward closing the compliance gap.
Why Standard Email Is Not HIPAA-Compliant
Many healthcare organizations run on Gmail (Google Workspace) or Microsoft 365, and most assume they’re protected because encryption exists somewhere in the stack. That assumption is the single most common — and most dangerous — misconception in healthcare email security.
Here’s the problem: standard email services use opportunistic TLS by default. TLS is attempted between mail servers, but if the receiving server doesn’t support it, the message is delivered anyway — unencrypted, in plaintext. Neither the sender nor the recipient typically sees a warning. The email just goes through.
This isn’t a hypothetical edge case. IT professionals managing healthcare email infrastructure have flagged this exact issue directly: opportunistic TLS is often enabled by default and creates a false sense of security, since it offers no guarantee that a given message, including one containing PHI, won’t be transmitted in plaintext if the recipient’s mail server doesn’t support encryption. Organizations assume they’re protected simply because TLS is technically “on,” without realizing it isn’t enforced.
That gap has real consequences under HIPAA. The Security Rule currently treats transmission encryption as an “addressable” safeguard, meaning covered entities can, in theory, implement an equivalent alternative measure instead. In practice, regulators and auditors from the Office for Civil Rights (OCR) expect enforced encryption as the standard of care. “Addressable” has never meant optional — it means an organization needs a documented, defensible reason if it isn’t doing enforced encryption, and few reasons hold up under scrutiny. Finally, under OCR’s proposed changes to the HIPAA Security Rule for ePHI, scheduled for final publication in July 2027, email encryption moves from addressable to mandatory.
Beyond the encryption gap, standard consumer and even most business email plans typically lack:
A BAA that’s actually offered and signed (available on some enterprise tiers, but not automatic)
Audit logging sufficient to meet HIPAA Security Rule requirements
Built-in encryption at rest guarantees for stored messages
None of this means Gmail or Microsoft 365 are inherently insecure products. It means their default configuration is built for general business use, not for an environment where every misrouted or intercepted message carries breach notification liability. Making either platform HIPAA-appropriate requires layering on additional tools, policies, and critically, a provider relationship that includes a signed BAA covering the exact services in use.
The Technical Components of Secure Email
Secure email is built upon five technical layers. Understanding each one, and where it fails in standard email, clarifies exactly what a compliant solution needs to deliver.
Encryption in Transit (TLS)
Transport Layer Security (TLS) encrypts the connection between mail servers as a message travels from sender to recipient. There are two flavors, and the difference between them is the crux of most healthcare email compliance failures:
Opportunistic TLS attempts an encrypted connection but falls back to unencrypted delivery if the receiving server doesn’t support it. This is the default across most consumer and business email platforms.
Enforced TLS requires an encrypted connection for delivery to succeed. If encryption can’t be established, the message fails to send rather than going out in plaintext, or a link to secure portal can be sent to securely access the information.
HIPAA’s Security Rule lists encryption as addressable, but enforced TLS has become the de facto standard that auditors and OCR expect from covered entities and business associates handling PHI over email. As one healthcare IT professional put it while debating this exact tradeoff internally: the goal is to require TLS for all outbound email and then document the remaining controls around it, treating enforced TLS as the technical baseline, with policy and process built on top.
Encryption at Rest
Transit encryption only protects a message while it’s moving. Once it lands on a mail server — sender’s outbox, recipient’s inbox, backups, archives — it needs to remain encrypted in storage. This is encryption at rest, and it’s where many organizations underestimate their exposure.
Encryption in transit alone offers zero control over a message after it’s been delivered. If the destination server isn’t itself encrypting stored data, or if a backup snapshot is taken without encryption, PHI sitting in an inbox is exposed regardless of how securely it arrived. HIPAA’s Security Rule requires safeguards for ePHI both in transit and at rest, a compliant secure email provider needs to guarantee both, not just one.
End-to-End Encryption (S/MIME, PGP)
End-to-end encryption (E2EE) encrypts message content itself, not just the connection it travels over — meaning even the email provider can’t read the content. Two standards dominate here:
S/MIME uses certificate-based encryption and is common in enterprise environments, such as healthcare, particularly where organizations already manage a public key infrastructure.
PGP (Pretty Good Privacy) uses a public/private key model and is more common in technical or security-conscious communities, though it’s less frequently deployed at scale in healthcare due to key management complexity.
E2EE isn’t a baseline requirement for every PHI-containing email, enforced TLS plus encryption at rest satisfies most use cases. But it becomes necessary for especially sensitive communications, cross-organization data sharing where you don’t control the recipient’s infrastructure, or when a business associate agreement specifically requires it.
Authentication (SPF, DKIM, DMARC)
These three protocols work together to prevent domain spoofing and email impersonation, a growing attack vector against healthcare organizations specifically, given how often phishing campaigns impersonate providers, payers, or patients.
SPF (Sender Policy Framework) specifies which mail servers are authorized to send email on behalf of a domain.
DKIM (DomainKeys Identified Mail) adds a cryptographic signature verifying a message wasn’t altered in transit.
DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do when SPF or DKIM checks fail, and provides reporting visibility.
Without these configured correctly, an organization’s domain can be spoofed to send convincing phishing emails to patients or staff, creating a security failure that compounds the compliance risk of email interception.
Digital Signatures
Digital signatures verify sender identity and confirm a message hasn’t been tampered with between sending and receipt. Paired with encryption, they close the loop on message integrity, confirming not just that content was protected, but that it came from who it claims to have come from and arrived unaltered.

What Makes Email HIPAA-Compliant Specifically
Technical safeguards alone don’t make email HIPAA-compliant. Compliance is a combination of technology, contracts, and documented processes — all four need to be in place simultaneously. This includes:
A signed BAA with your email provider – Any vendor that transmits, processes, or stores PHI on your behalf is a business associate under HIPAA, and business associates are legally required to sign a BAA before handling that data. Email providers have persistent access to ePHI — even end-to-end encrypted messages pass through their infrastructure at some point — which makes this requirement absolute, not situational. If a provider won’t sign a BAA, using them to send or store PHI isn’t a compliance risk you can mitigate; it’s a violation from the start.
Encryption as an addressable safeguard – Under 45 CFR §164.312(e)(2)(ii), the HIPAA Security Rule lists encryption of ePHI in transit as “addressable” rather than strictly “required.” In practice, this doesn’t mean optional, it means an organization must implement it, or document and justify an equivalent alternative safeguard. Enforced encryption has become the expected standard, and with the newly proposed HIPAA Security Rule planned for July 2027 publication, NPRM would formalize that expectation by making encryption of ePHI in transit and at rest mandatory rather than addressable. Organizations still relying on opportunistic TLS as their “equivalent alternative” should treat this as a closing window.
Access controls and audit logs – HIPAA requires the ability to track who accessed PHI, when, and what they did with it. This means role-based access permissions, multi-factor authentication, and a complete, retained audit trail — not just for compliance reporting, but for identifying and responding to incidents quickly.
The encryption safe harbor – This is one of the most consequential, and most underused, provisions in HIPAA. If PHI is sent via properly encrypted email and ends up misdirected to the wrong recipient, it is not a reportable breach under the Breach Notification Rule, because the encrypted content is considered unreadable and therefore not “unsecured PHI.” The exact same misdirection with unencrypted email is a reportable breach, triggering notification obligations to the individual and to HHS/OCR. Encryption isn’t just a security best practice here, it’s the line between a non-event and a formal breach investigation.
HITRUST certification as a trust signal – When evaluating vendors, HITRUST CSF certification is a strong external indicator that a provider’s security controls have been independently assessed against a recognized healthcare-specific framework. It’s not a HIPAA requirement in itself, but it meaningfully reduces the diligence burden on your side when vetting a provider.
Types of Healthcare Email That Must Be Secure
Not all internal debate here is about “should we secure email” — it’s about scope. Which specific email flows actually carry PHI, and therefore need to run through a compliant channel? In practice, the answer is broader than most teams initially assume.
The common thread: if a message references anything that could identify a patient in connection with health information — a name next to a diagnosis, an account number tied to a service date, an annual test reminder — it needs to move through a secure channel, regardless of whether it’s clinical, financial, or administrative in nature.
How to Evaluate a Secure Email Provider for Healthcare
Vendor evaluation in this category tends to go one of two ways: teams either take a provider’s “HIPAA-compliant” label at face value, or they get buried in RFP questions without knowing which answers actually matter. Ask these key questiosn to focus the evaluation on what’s operationally and legally significant.
“Does the provider sign a BAA? This is the first filter, not the last. If a vendor won’t sign a BAA — or offers a heavily limited one — everything else is irrelevant. Some organizations go a step further and negotiate indemnity or make-whole clauses into the BAA itself, seeking financial protection beyond the baseline liability allocation.
What encryption methods are supported? Confirm specifically whether the provider offers TLS only, or also supports S/MIME and/or PGP for end-to-end encryption where needed. TLS-only coverage is sufficient for most standard PHI communication; organizations with cross-border data sharing or especially sensitive use cases may need E2EE options available.
Is encryption enforced or opportunistic? This is the single most important technical question to ask directly, in those terms. A vendor that describes its encryption vaguely, without distinguishing enforced from opportunistic delivery, hasn’t answered the question. Push for specifics.
How are large attachments handled? Lab results, imaging files, and clinical documents often exceed standard attachment size limits. Confirm the provider has a secure, compliant method for large file transfer that doesn’t force users onto an unencrypted workaround.
What audit logging and reporting capabilities exist? You need visibility into delivery, access, and any failed encryption attempts, not just a generic sent/received log. Ask whether logs are retained for a period consistent with your organization’s HIPAA documentation requirements.
Do they support high-volume transactional email? Appointment reminders, billing notices, and patient communications at scale require infrastructure built for volume without sacrificing per-message compliance. Confirm the provider’s platform is built for this your specific pattern, not just person-to-person messaging.
Is the platform US-based with US data residency? For many healthcare organizations, where data physically resides — and under which jurisdiction — is a material factor in vendor risk assessment, particularly for payers and larger provider organizations with strict data governance policies.”
One operational factor worth weighing alongside these questions: secure email portals — the kind that require recipients to click through to a separate web page to read a message — solve the encryption problem but often create a real adoption problem. IT teams have reported a direct conflict between phishing-awareness training and portal-based workflows: staff and patients trained not to click suspicious links in emails are, understandably, reluctant to click the “secure link” a portal email contains. This is a legitimate reason many organizations increasingly prefer platforms that enforce encryption transparently in the background — like LuxSci’s SecureLine encryption technology — rather than routing every message through a separate portal experience.
Secure Email Checklist for Healthcare Organizations
Every safeguard covered in this guide comes down to a handful of concrete, verifiable actions. Use the checklist below as a working reference for what needs to be in place across your legal agreements, technical controls, and internal processes. This is not a one-time setup task, but something worth revisiting as your email volume, vendors, and regulations evolve. Share it across your compliance and IT teams as a starting point for an internal audit.
Legal and Contractual – BAA signed with email provider and all third-party vendors handling PHI.
Encryption – Forced TLS, not opportunistic only for emails in transit and all stored data encrypted with AES-256 bit encryption.
Access and Audit – Unique user IDs, role-based access, and login monitoring with advanced MFA enabled for all email accounts; audit logs active and maintained.
People and Processes – Staff trained in PHI handling, established breach response plan, annual email security policy review.
What Should I Do Now?
Secure email isn’t a single setting you switch on — it’s a combination of enforced encryption, a signed BAA, access controls, and documented process working together. Get any one piece wrong, and the rest doesn’t hold up under an OCR audit or a breach investigation.
If your organization is still relying on opportunistic TLS, an unsigned or incomplete BAA, or a patchwork of workarounds to move PHI through email, now is the time to close that gap, especially with the proposed 2025 HIPAA Security Rule update poised to make encryption a mandatory requirement rather than an addressable one in 2027.
Below are three ways you can continue your journey to securing your healthcare email:
Email can be HIPAA compliant, but only when the right safeguards are in place — enforced encryption, a signed BAA with your email provider, access controls, audit logs, and staff training on PHI handling. Standard email without these safeguards is not compliant.
2. Do I need to sign a BAA with my email provider?
Yes. Email providers have persistent access to ePHI — even encrypted messages pass through their servers — making them Business Associates under HIPAA. A signed BAA is required. If your provider won’t sign one, you cannot legally use them to send or store PHI.
3. What is the difference between opportunistic TLS and enforced TLS — and which does HIPAA require?
Opportunistic TLS attempts encryption but falls back to plaintext if the recipient’s server doesn’t support it. Enforced TLS stops delivery rather than sending unencrypted. HIPAA’s Security Rule treats transmission encryption as an addressable specification, in practice, enforced TLS is the standard auditors and OCR expect. The proposed 2025 HIPAA Security Rule NPRM would make encryption of ePHI in transit a mandatory requirement in 2027.
4. What happens if I send PHI in an unencrypted email?
It is an impermissible disclosure under HIPAA’s Privacy Rule and triggers the Breach Notification Rule, requiring you to notify the individual and HHS/OCR within 60 days. Penalties range from $100 to $50,000 per violation. Had the email been properly encrypted, the same incident would qualify for HIPAA’s encryption safe harbor, meaning no notification required.
5. Is Gmail or Microsoft 365 HIPAA compliant for sending patient emails?
Neither is compliant in their default configuration. Both use opportunistic TLS, meaning PHI can be sent in plaintext if the recipient’s server doesn’t support encryption. A signed BAA is available on enterprise plans but doesn’t close the technical gap alone. A purpose-built HIPAA-compliant email platform is the reliable solution.
If you’ve been waiting for the final word on the new HIPAA Security Rule before you touch your email encryption strategy, you now have an official reason to keep waiting.
Our advice: Don’t do it.
What is the new HIPAA Security Rule for ePHI?
The Department of Health and Human Services’ Office for Civil Rights had targeted May 2026 for a final rule implementing the most significant update to the HIPAA Security Rule in over two decades. The proposal eliminates the “addressable” standard and makes encryption of ePHI in transit and at rest mandatory for every covered entity and business associate. That deadline came and went quietly. Now we know why: an updated federal regulatory agenda shows OCR’s timeline has moved to July 2027, with the rule-making downgraded from “final rule stage” to “long-term action.” OCR is still working through more than 4,700 public comments on the January 2025 proposal.
For an industry that had been expecting a tighter deadline, a year-plus delay is the kind of news that invites a collective exhale — and a shelved project plan. At LuxSci, we think that would be a mistake, for three reasons:
The current rule already requires you to address encryption. “Addressable” was never “optional.” It has always meant you must implement the safeguard, implement an equivalent alternative, or document in writing why neither is reasonable for your organization. Most healthcare organizations have never done that documentation rigorously, and OCR’s existing enforcement authority applies today, not in 2027.
Breach costs haven’t waited for the rule.IBM’s 2025 Cost of a Data Breach Report puts the average healthcare breach at $7.42 million, still the highest of any industry. At the same time, email remains the number one attack vector into healthcare organizations. None of that risk is paused by a regulatory delay.
Delay is not withdrawal.OCR has not signaled it’s abandoning the encryption mandate, only that it’s taking longer to finalize it. Organizations that build now toward the standard already proposed will be ahead (and more secure) regardless of exactly when, or in what final form, the rule lands. Organizations that wait risk a compressed scramble once it does.
What should healthcare IT and compliance leaders actually do with this news?
Reevaluate your ePHI security posture, recalibrate its urgency, and use the extra runway to do the job right, instead of racing against a deadline. This includes:
Getting a real inventory of where ePHI moves by email today, inbound and outbound, and where encryption is inconsistent or absent.
Closing the documentation gap on “addressable” now, while you have time to do it well rather than defensively.
Pushing your email vendor for concrete answers on encryption standards, MFA enforcement, audit logging, and breach notification — the same technical controls the proposed rule would make mandatory.
Building (or updating) a written, enforcement-ready posture: policies, vendor agreements, certifications and verifications, test results, and training records that would hold up under an OCR investigation today, not just in a future compliance deadline.

If you are one of the 92% of Americans with an email address, you are likely familiar with email marketing. It is a tried and true marketing strategy that delivers a superior return on investment compared to other digital channels. However, when healthcare organizations want to utilize these strategies, out-of-the-box solutions are not a good fit. Healthcare organizations must utilize email marketing platforms specifically designed to meet HIPAA’s unique privacy and security requirements.
When Do You Need a HIPAA-Compliant Email Marketing Platform?
Healthcare organizations are required to use a HIPAA-compliant email for HIPAA marketing because their messages often contain electronic protected health information (ePHI). This includes information that is both individually identifiable and relates to someone’s healthcare.
Individually identifiable information includes identifiers like a patient’s name, address, birth date, email address, social security number, and more. By default, every email marketing communication includes the patient’s email address and is, therefore, individually identifiable. Not only does the definition of ePHI cover people’s past, present, and future health conditions, but it also includes treatment provisions and billing details. This information is often contained in email marketing messages.
While the law does not cover anonymous health details or individual identifiers sent by themselves, you must be careful and abide by HIPAA regulations when the two are brought together. You will need a HIPAA-compliant email marketing service whenever you send ePHI. As we will see, even if you think an email may not contain ePHI, it is still best to be cautious.
Types of HIPAA-Compliant Email Marketing Communications
An excellent example of an email blast that must comply with HIPAA is a newsletter sent to a clinic’s cancer patients. At first glance, the email doesn’t contain any specific PHI. It doesn’t mention Jane Smith’s chemotherapy treatments, other specific patients, or their medical information. However, upon closer look, it may violate HIPAA regulations.
Every email in this campaign contains a personal identifier- the patient’s email address. In this example, only cancer patients received the newsletter, which also tells you personal medical information. A hacker could infer that anyone who received this email has cancer, which is ePHI and protected under HIPAA. If you use a medical condition to create a segment of email recipients, the email campaign must comply with HIPAA.
Sometimes, it can be challenging to identify if an email contains ePHI. If you sent the same practice newsletter to a list of all current and former medical clinic patients, it may or may not contain ePHI. Even if the newsletter contained benign info about the practice’s operating hours or parking information, if the practice is centered around treating a specific condition like cancer or depression, it may be possible to infer information about the recipients regardless of the message.
There are a lot of gray areas, and it can be difficult to determine if an email contains PHI. We recommend using HIPAA-compliant email marketing for any promotional materials to reduce the risk of violations.
The Benefits of Using a HIPAA-Compliant Marketing Platform
After reading this, you may think the answer is to avoid sending PHI in email campaigns. However, by keeping your communications bland, generic, and broadly targeted, you miss out on significant opportunities to engage your patients.
Using a HIPAA-compliant email marketing solution, you can leverage ePHI to send much more effective messages. In the above example, cancer patients actively receiving treatment at your clinic are much more likely to be interested in your business updates. Targeted emails receive much higher open and click rates than those sent to a general list.
Sending the right information to your patients at the right time is an effective patient engagement strategy. Think about it using an e-commerce example- when a retailer sends you product recommendations based on past purchases; they use your data to influence future purchasing decisions. By utilizing patient data to create highly relevant and personalized campaigns and offers, you receive a better return on investment in your efforts.
What is Required for HIPAA-Compliant Email Marketing?
Finding the right HIPAA-compliant email marketing platform can be challenging. Most of the common vendors aren’t HIPAA-compliant at all. Others claim compliance and will sign BAAs to protect your information at rest but still will not enable you to send PHI via email. Finding a provider that suits your business needs and protects the email messages requires careful vetting.
Generally speaking, a HIPAA-compliant email platform must meet three broad requirements:
The vendor will sign a Business Associates Agreement that outlines how they will protect your data and what happens in case of a breach.
The vendor protects the data at rest using appropriate storage encryption, access controls, and other security features.
The vendor protects messages in transit using an appropriate level of encryption with the proper ciphers.
Thankfully, LuxSci’s Secure Marketing email platform has been designed to meet the healthcare industry’s unique needs. Our platform was built with both security and compliance at the forefront. With Secure Marketing, organizations can send fully HIPAA-compliant email marketing messages to the right patients at the right time and receive a better return on their marketing investment.
For healthcare organizations, choosing the right product and service vendors is essential for achieving HIPAA compliance. One of the key prerequisites of a HIPAA-compliant vendor is the willingness to sign a Business Associate’s Agreement (BAA): a legal agreement that outlines both parties’ responsibilities and liabilities in securing protected health information (PHI).
However, despite what some healthcare organizations have been led to believe, simply signing a BAA with a vendor doesn’t guarantee your use of their product or service will be HIPAA-compliant. In reality, a BAA is just the beginning, and there are several subsequent actions both healthcare organizations and their supply chain partners must take to ensure the compliant use of PHI, especially over communications channels like email.
With this in mind, this post explores some of the reasons why signing a BAA on its own doesn’t ensure the security of PHI and protect your organization from HIPAA violations.
Business Associate Agreements (BAAs) Explained
As touched upon above, a BAA is a legally-binding document established between a covered entity (CE), i.e., healthcare organizations, and a business associate (BA), i.e, any company that handles PHI in providing a CE with products or services. For a BA to handle patient or customer data on behalf of a CE, following HIPAA regulations, there mustbe a BAA in place.
A BAA details:
Each party’s roles, responsibilities, and liabilities in securing PHI.
The permitted uses of PHI by the BA and, conversely, restrictions on any other use.
The BA’s responsibilities in implementing appropriate administrative, technical, and physical security measures to best protect PHI.
The BA’s obligations to report any unauthorized use, disclosure, or breach of PHI.
That the BA is required to assist with patient rights support, i.e., data access, amendments, and accounting of disclosures, when appropriate.
The BA’s obligations in making records available for audits or investigations.
The CE’s right to terminate the contract if the BA fails to fulfil their obligations in safeguarding PHI.
Additionally, if a BA employs a third-party company, i.e., a subcontractor, that will have access to a CE’s PHI, they are required to establish a BAAwith that company. This then makes the subcontractor a “downstream BA” of the CE, and subject to the same obligations and restrictions placed on the original BA. This ensures the security protections mandated by HIPAA flow down the entire chain of custody for sensitive patient and customer data.
Compliance Considerations After Signing a Business Associate Agreement (BAA)
Now that we’ve covered what a BAA is and the role it plays in ensuring data privacy, let’s move on to exploring some of the key things you have to do following the singing of a BAA to ensure HIPAA compliance.
1. Both Parties Must Implement HIPAA-Required Data Risk Mitigation Measures
First and foremost, while a BAA details each party’s respective responsibilities in implementing measures to protect PHI, both still actually need to implement those required security features to achieve HIPAA compliance.
The measures required under HIPAA’s Security Rule, including encryption and access control, are designed to mitigate and minimize the impact of data breaches. So, if a company suffers a security breach and later audits show the required security policies and controls were not in place, they would be subject to the consequences of HIPAA violations, including fines and reputation damage.
Also, while a BAA stipulates that the BA is responsible for implementing the HIPAA-required safeguards for the PHI under their care, it doesn’t specify exactly which security measures they must implement. Subsequently, that’s left to the BA to interpret based on their understanding of HIPAA requirements, and how they conduct their required risk assessments.
For example, if you have a BAA with your email services provider, that alone may not be enough to keep your company or organization HIPAA compliant. That’s because the provider may not have the security measures your organization needs, and instead have a carefully worded BAA that will leave you vulnerable.
Let’s say your email marketing service provider is a “semi-HIPAA compliant” provider. In these cases, they may not offer email encryption, or the necessary access control measures your organization needs to send PHI and other sensitive information safely. The so-called HIPAA compliance may be limited only to data stored at rest on their servers only.
In short, although a BAA outlines each party’s commitment to securing data, both parties still have to follow through on implementing risk mitigation measures. Additionally, though a healthcare company has its BA’s assurances that they’ll have the appropriate safeguards in place, CEs often only have limited visibility into its ongoing security posture. As a result, asking the right questions and working with a proven HIPAA compliant provider are critical steps healthcare organizations must take to ensure full compliance.
2. CEs Must Stick to “In-Scope” Services
While a BA may provide a CE with a range of services, many limit the coverage of their BAAs to particular “in-scope” services. As a result, if a healthcare organization were to use a service outside the coverage of the BAA, i.e., an “out-of-scope” service, they’d risk exposing patient data and incurring HIPAA violations.
And, even when a service is in-scope, the BA is still required to configure it properly for it to be compliant. These configurations could include:
Enabling encryption
Establishing access control
Activating multi-factor authentication (MFA)
Turning on audit logging
With this in mind, it’s crucial to ensure that the “complete” service or tool – not just a part of it – is covered by a BAA before using it to process PHI. Similarly, check the terms of your BAA for configuration or security best practices that offer guidance on fully HIPAA compliant use, and make sure your responsibilities as a CE are 100% clear.
3. Staff Must Be Trained to Securely Handle PHI
Another key reason that signing a BAA doesn’t automatically result in HIPAA compliance is the likely need for both parties to educate their staff on how to securely handle sensitive data, such as PHI.
Firstly, as discussed above, only some of the services offered by a BA may be covered by its agreement. Subsequently, a healthcare organization’s employees need to be sufficiently trained on the use and disclosure of PHI, namely, the services in which they’re permitted to process PHI and which, in contrast, services are non-compliant.
By the same token, as well as implementing the stipulated safeguards, BAs are responsible for training their workforce on how to use and, where appropriate, configure them. This will help ensure the limited, correct use and disclosure of PHI as allowed by the BAA.
4. Reporting Requirements
A BAA stipulates that a BA must notify the CE in the event of improper or unauthorized use of PHI. More specifically, this includes:
Reporting immediately any use or disclosure not permitted by the terms of the BAA.
Notifying the CE of security incidents resulting in the potential exposure of PHI.
However, the commitment to reporting in the BAA and the ability to deliver on that commitment are two different things entirely. Firstly, the BA must implement the policies and infrastructure that allow for timely incident reporting. This includes conducting risk analysis, implemeting continuous monitoring, and developing a robust incident response plan.
Additionally, a key aspect of prompt, comprehensive reporting includes the BA ensuring that their staff are sufficiently trained to detect and report security events. As part of their training on the secure handling of PHI, a BA’s employees must be able to recognize common security issues and threats, such as improper email configurations and phishing attempts, and how to report them.
5. Subcontractor BAAs
While CEs must sign BAAs with their BAs for the compliant use and disclosure of PHI, they don’t have to sign such agreements with any subcontractors the BA may employ. Instead, it’s the responsibility of the BA to enter into their own business associate agreements with their subcontractors. As a result, the original security obligations are passed all the way down the data’s chain of custody.
While a CE can take certain measures to enforce this, such as requesting proof of subcontractor BAAs – or even the ability to review subcontractors before beginning engagement – ultimately, they have little control over their security postures. Ultimately, this means that they have to trust that the original service BA does their due diligence in selecting security-minded subcontractors, with the right PHI safeguards in place.

Learning how to send HIPAA compliant emails requires understanding encryption standards, authentication protocols, and business associate agreements that protect patient health information during electronic transmission. Healthcare providers must implement safeguards when communicating electronically about patients, ensuring that all email communications meet HIPAA Security Rule requirements for protecting electronic protected health information. Standard consumer email services like Gmail or Outlook cannot guarantee the security measures necessary for healthcare communications, making specialized secure email platforms essential for organizations handling patient data.
Encryption Requirements for Healthcare Email
End-to-end encryption is the foundation for secure healthcare email communications, protecting patient information from unauthorized access during transmission and storage. Healthcare organizations learning how to send HIPAA compliant emails need email systems that encrypt messages using Advanced Encryption Standard (AES) 256-bit encryption or equivalent security protocols before sending communications across public internet networks. The encryption process must protect both the email content and any attachments containing protected health information, ensuring that even if messages are intercepted, the patient data remains unreadable to unauthorized parties.
Message encryption should activate automatically for all healthcare communications rather than requiring manual activation by individual users. This automatic encryption prevents inadvertent transmission of unprotected patient information when staff members forget to activate security features manually. Healthcare email systems also need secure key management protocols that protect encryption keys from unauthorized access while ensuring that legitimate recipients can decrypt and read necessary patient communications.
Transport layer security protocols provide protection during email transmission, creating secure connections between email servers and preventing message interception during delivery. Healthcare organizations should verify that their email providers use TLS 1.2 or higher encryption standards for all message transmissions. Certificate-based authentication adds another security layer by verifying the identity of email recipients before allowing message delivery, preventing misdirected emails containing patient information from reaching incorrect recipients.
Authentication and Access Controls
Multi-factor authentication is a security requirement for healthcare email systems, ensuring that only authorized users can access accounts containing patient communications. Healthcare staff need to provide at least two forms of identification before accessing secure email accounts, combining passwords with mobile device codes, biometric verification, or hardware security tokens. This authentication process protects against unauthorized account access even if passwords are compromised through data breaches or social engineering attacks.
User access controls must reflect the principle of least privilege, granting healthcare staff access only to email communications necessary for their job functions. Physicians need different access levels compared to administrative staff, with role-based permissions preventing unauthorized viewing of patient information outside individual staff members’ care responsibilities. Email systems should maintain detailed audit logs tracking who accesses patient communications, when access occurs, and what actions users perform with protected health information.
Automatic session timeouts provide security by logging users out of email systems after predetermined periods of inactivity. These timeouts prevent unauthorized access when staff members step away from their workstations without properly securing their accounts. Password complexity requirements and password updates strengthen authentication security, though healthcare organizations must balance security requirements with usability to prevent staff from circumventing security measures due to overly complex requirements.
Session management protocols should track concurrent login attempts and prevent multiple simultaneous access sessions for individual user accounts. This monitoring helps detect potential account compromises when unusual access patterns occur, such as logins from multiple geographic locations within short time periods. Email systems need clear protocols for immediately revoking access when staff members leave the organization or when security breaches are detected.
Business Associate Agreements and Compliance
Healthcare organizations must establish comprehensive business associate agreements with their email service providers before transmitting any patient information through electronic communications. These legal agreements define the responsibilities and obligations of both parties regarding protected health information, specifying how the email provider will protect patient data, what uses and disclosures are permitted, and how security incidents will be reported to the healthcare organization. The agreements must cover encryption requirements, data retention policies, and procedures for returning or destroying patient information when business relationships end.
Vendor due diligence processes help healthcare organizations evaluate email service providers to ensure they understand how to send HIPAA compliant emails while meeting all regulatory requirements. This evaluation includes reviewing security certifications, examining data center facilities and security controls, and verifying the provider’s experience with healthcare industry regulations. Healthcare organizations should require proof of cyber liability insurance, incident response capabilities, and security auditing from their email service providers.
Compliance monitoring requires healthcare organizations to conduct periodic assessments of their email security measures and vendor performance. These assessments verify that encryption standards remain current, access controls function properly, and audit logging captures all necessary security events. Healthcare organizations must maintain documentation demonstrating their compliance efforts, including training records, security policies, and incident response procedures related to email communications.
Risk assessments help identify potential vulnerabilities in email security systems and guide updates to security measures as threats evolve. Healthcare organizations should review their email compliance programs annually or whenever changes occur to their operations, technology systems, or regulatory requirements. Documentation of these assessments provides evidence of due diligence in protecting patient information during regulatory audits or security investigations.
Implementation Best Practices
Staff training programs must educate healthcare workers about proper email security practices and when it is appropriate to include patient information in electronic communications. Healthcare staff learning how to send HIPAA compliant emails need clear guidelines about what patient information can be discussed via email versus what requires telephone calls or in-person meetings. Training should cover how to recognize secure email platforms, how to verify recipient identities before sending patient information, and what types of patient data require protection beyond standard email security measures.
Email policy development requires healthcare organizations to establish clear protocols governing patient communication via electronic means. These policies should specify which staff members can send patient information via email, what approval processes are required for sharing sensitive patient data, and how to handle requests from patients who want to receive their health information via email. Policies must also cover how to respond when staff accidentally send patient information to incorrect recipients or when security breaches involving email communications occur.
Testing procedures should verify that email security measures function correctly before implementing systems organization-wide. Healthcare organizations learning how to send HIPAA compliant emails need to conduct penetration testing of their email security systems, verify that encryption activates properly, and confirm that access controls prevent unauthorized viewing of patient information. Testing schedules help identify security vulnerabilities before they can be exploited by malicious actors.
Incident response planning prepares healthcare organizations to handle security breaches involving email communications containing patient information. Response plans should include procedures for containing security incidents, assessing the scope of potential patient information exposure, and notifying affected patients and regulatory authorities when breaches occur. Healthcare organizations must practice their incident response procedures to ensure staff can respond effectively during actual security emergencies.
Patient Communication Considerations
Patient consent requirements vary depending on the type of health information being transmitted and the communication method requested by patients. While healthcare providers can generally communicate with patients about treatment, payment, and healthcare operations without authorization, organizations should obtain written consent before sending detailed medical information via email. Consent forms should explain the security measures in place while acknowledging that email communication carries inherent privacy risks despite protective measures.
Email content guidelines help healthcare staff understand what patient information is appropriate for electronic transmission versus what requires more secure communication methods. Those mastering how to send HIPAA compliant emails recognize that laboratory results, medication changes, andappointment reminders may be suitable for secure email communication, while detailed psychiatric notes, HIV test results, or substance abuse treatment information may require protections or alternative communication methods. Staff need clear decision-making frameworks for evaluating the appropriateness of email communication for different types of patient information.
Alternative communication methods should remain available for patients who prefer not to receive health information via email or who lack secure email access. Understanding how to send HIPAA compliant emails includes recognizing when alternative methods like telephone calls, patient portals, and postal mail provide more appropriate secure alternatives for patient communication while ensuring that lack of email access does not create barriers to necessary healthcare information sharing. Healthcare organizations must accommodate patient preferences while maintaining appropriate security measures for all communication methods.
