Digital technologies have entirely shifted how individuals want to interact with their healthcare providers. As consumers have become used to emailing or texting with their hairstylists, mechanics, and other providers to schedule appointments, they want to have the same level of interaction with their healthcare providers.
However, many healthcare organizations find it challenging to deliver the same experience because of their compliance requirements under HIPAA. They must balance usability and access with security and patient privacy. To send secure emails, they often resort to secure web portals.
Problems with Secure Web Portals
One of the most common ways that healthcare organizations communicate securely with patients is by using the secure web portal method of email encryption. In this scenario, messages are sent to a secure web server, and a notification is sent to the recipient, who then logs into the portal to retrieve the message.
While highly secure, this method is not popular with recipients because of the friction it creates.
To maintain a high level of security, users must log in to a separate account to retrieve the message. This extra step creates a barrier, especially for individuals who are not tech-savvy. In addition to creating a new account, they must remember a different username and password to access their secure messages. If the recipient doesn’t have this information readily available, they will likely delete the message and move on with their day. Many users will never bother logging in because of the inconvenience. This creates issues for organizations that want to use email for standard business communications and patient engagement efforts.
While this method may be appropriate for sending highly sensitive information like medical records, financial documents, and other valuable information, many emails that must meet compliance requirements only infer sensitive information and do not require such a high level of security. Flu shot reminder emails are not as sensitive or potentially devastating as sending the wrong medical file to someone. Healthcare organizations need to use secure email solutions that are flexible enough to send only the most sensitive emails to the portal and less sensitive emails using other methods.
How to Meet Compliance Requirements for Sending Secure Email
So, what other options do you have for sending secure emails? The answer will depend on what specific requirements you need to meet. Healthcare organizations that must abide by HIPAA regulations will find a lot of flexibility regarding the technologies they can use to protect ePHI in transit.
In addition to a secure web portal, three other types of encryption are suitable for email sending: TLS, PGP, and S/MIME. PGP and S/MIME are more secure than a web portal. They also require advanced technological skills and coordination with the end-user to implement, which makes them impractical for most business email sending.
That leaves us with TLS, which is suitable to meet most compliance standards (including HIPAA) and delivers an email experience much like that of a “regular” email.
Send Secure Emails with TLS Encryption
TLS encryption is an excellent option for secure email sending that provides a seamless experience for the recipient. Emails sent securely with TLS appear like regular, unencrypted emails in the recipient’s inbox.
TLS encrypts the message contents as they travel between mail servers to prevent interception and eavesdropping. Once the message reaches the inbox, it is unencrypted and can be read by anyone with access to the email account. For this reason, it is less secure than a portal but secure enough to meet compliance requirements like HIPAA.
If you’re wondering why this is, HIPAA only requires covered entities and business associates to protect PHI when it is stored on their systems or as it is transmitted elsewhere. After the message reaches the recipient, it is up to the recipient to decide what they want to do to secure the information. HIPAA does not apply to individuals. Each person is entitled to share and store their health information however they see fit.
Conclusion
Balancing security and usability is a significant challenge for healthcare organizations. If the message is too secure, it may be difficult for the recipient to open and engage with it. If it’s not secure enough, it is too easy for cybercriminals and other bad actors to intercept private information as it is sent across the internet.

Secure email is not the same as “email with encryption turned on.” True secure email requires enforced automated encryption, a signed BAA, access controls, audit logs, and documented processes — not just a feature toggle.
Standard email platforms like Gmail and Microsoft 365 rely on opportunistic TLS by default, which can silently fall back to unencrypted delivery if the recipient’s server doesn’t support encryption.
HIPAA’s encryption safe harbor means a misdirected but properly encrypted email is a non-event. The same email sent unencrypted is a presumed breach unless a risk assessment shows otherwise.
A signed Business Associate Agreement (BAA) with your email provider is non-negotiable — without one, you cannot legally send or store PHI through that provider.
The proposed 2025 HIPAA Security Rule update, planned for finalization in 2027, would make encryption of ePHI in transit and at rest a mandatory requirement rather than “addressable,” raising the stakes for organizations still relying on opportunistic TLS.
Best for: Healthcare IT Directors, Compliance Officers, Privacy Officers, and Marketing Managers at provider, payer, and supplier organizations that handle protected health information (PHI).
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.

Most healthcare organizations view email as a utility, a necessary tool for sending messages between staff, communicating with patients, sending out newsletters, connecting workflows, and so on. Historically, IT teams focused on keeping it running, security teams worried about phishing, and compliance teams made sure sensitive emails were encrypted.
Today, however, that view is rapidly becoming outdated.
Email has evolved into one of healthcare’s most critical digital infrastructure components, and also one of it’s biggest security threats. It’s a core channel for patient engagement, care coordination, revenue cycle operations, digital marketing, remote monitoring, and increasingly, AI-powered communications. The organizations that recognize this shift are building communications platforms designed for security, performance, automation, and growth. With the new HIPAA Security Rule requiring email encryption on the horizon, those companies that don’t may find themselves constrained by systems that were never intended to support modern healthcare.
Email Is No Longer Just a Messaging Tool
Healthcare organizations now depend on email to support dozens of mission-critical workflows every day.
Patients receive appointment reminders, registration instructions, imaging results, billing notifications, Explanation of Benefits (EOBs), prescription updates, preventive care reminders, patient education, and post-discharge follow-up. Marketing teams deliver personalized wellness campaigns and service line promotions. Clinical systems generate transactional notifications. Revenue cycle teams rely on secure digital communications to accelerate payments and reduce paper costs.
For many organizations, mission-critical patient communications flow through email every month.
When viewed collectively, email is more than a simple communications channel. It has become operational infrastructure with high levels of security needed and increasing compliance requirements.
The Stakes Continue to Rise
As healthcare becomes more digital, every communication carries greater business and clinical importance.
A delayed billing email may postpone payment. A failed appointment reminder can increase no-show rates. An undelivered care management message may impact patient outcomes. A misconfigured security policy can expose protected health information (PHI). Poor deliverability can undermine expensive patient engagement initiatives before they ever reach the inbox.
These are no longer isolated IT issues. Email can affect revenue, patient satisfaction, operational efficiency, compliance, and organizational reputation.
Today’s healthcare leaders require email infrastructure to provide the same reliability and visibility they demand from electronic health records, identity management systems, and other core infrastructure.
AI Is Raising the Bar Even Higher
There’s little doubt that artificial intelligence (AI) promises to transform patient communications.
Healthcare organizations everywhere are exploring AI-generated patient education, personalized outreach, intelligent scheduling, multilingual communications, and automated follow-up programs.
But AI also increases the importance of the underlying communications infrastructure.
Generating more personalized emails means little if organizations cannot:
Automatically protect PHI.
Apply consistent security policies.
Maintain complete audit trails.
Deliver messages reliably.
Integrate with EHRs, RCM and CRM platforms, and customer data platforms.
Demonstrate compliance during an audits.
In many ways, AI amplifies both the opportunities and the risks. Your email platform can help determine whether AI initiatives succeed or create new compliance and operational challenges.
Infrastructure Matters More Than Features
Healthcare buyers have traditionally evaluated email platforms based on individual features such as encryption, spam filtering, or secure portals.
Those capabilities remain important, but they no longer tell the whole story.
Today’s healthcare organizations should be evaluating communications platforms the same way they evaluate any mission-critical infrastructure.
Questions increasingly include:
Can it support both transactional and marketing communications?
Does it automatically enforce security policies without relying on user decisions?
Can it integrate with EHRs, CRM systems, CDPs, and business applications?
Will it scale during peak communication periods?
Does it provide detailed audit logging and reporting?
Can it adapt as regulatory expectations evolve?
Does it maintain high deliverability at enterprise scale?
Does it support single-tenant dedicated infrastructure for high performance and increased security?
These infrastructure characteristics often determine long-term success far more than any single feature comparison.
Email and the Future Of Secure Healthcare Communications
Healthcare is steadily moving toward a world where nearly every patient interaction is digital, personalized, and data-driven.
Healthcare leaders often ask whether they need a more secure email solution. That may be the wrong question.
The better question is whether their communications infrastructure is ready for where healthcare is headed over the next decade.

A HIPAA compliant form collects protected health information while meeting security, privacy, and patient authorization requirements set by the HIPAA Privacy and Security Rules. These forms include proper disclosure statements, patient signature capabilities, data encryption, access controls, and audit tracking features. Healthcare organizations use these forms for patient intake, consent, and information exchange while safeguarding patient data throughout the collection and storage process.
Required Elements of HIPAA Compliant Forms
Healthcare forms must include specific components to maintain HIPAA compliance. HIPAA compliant forms need clear authorization language explaining how patient information will be used and disclosed. Patient signature sections document consent for information sharing and establish when that authorization expires. Forms include statements about patients’ rights to revoke authorization and receive copies of their information. Healthcare providers use plain language that patients can understand rather than technical terminology. Privacy policy information and contact details for the privacy officer help patients address concerns. Effective forms contain statements about potential redisclosure limitations after information leaves the provider’s control.
Technical Security Features for Electronic Forms
Electronic HIPAA compliant forms require robust security measures to protect patient information. Forms use encryption during data transmission and storage to prevent unauthorized access. Access controls restrict form viewing and submission processing to authorized personnel with proper credentials. Secure hosting environments provide technical protections including firewalls and intrusion detection systems. Audit logs track when information was entered, viewed, or modified, creating accountability for all data access. Well-designed forms incorporate automatic timeout features that protect information on unattended devices. Data backup systems prevent information loss, while secure storage solutions protect electronic signatures. Form builders include security configuration options that administrators can customize based on their organization’s needs.
Implementing HIPAA Compliant Forms
Healthcare organizations benefit from following structured processes when developing compliant forms. The implementation begins with a review of what patient information needs collection and how it will be used. Many organizations offer both web-based and PDF form options to accommodate different user needs. Effective form creation tools include drag-and-drop builders that simplify development while maintaining compliance standards. Healthcare providers test forms thoroughly before deployment and train staff on proper usage procedures. Implementation plans typically include integration with existing systems like electronic health records and patient portals. Organizations establish procedures for securely storing completed forms according to HIPAA retention requirements.
HIPAA Compliant Form Accessibility
Forms work best when accessible across different devices and platforms to maximize patient convenience while maintaining security. Web-based forms provide flexibility for patients to complete paperwork before appointments. Mobile-responsive designs ensure forms display properly on smartphones and tablets. Modern form systems work with secure digital signature technology to eliminate paper-based processes. Cloud storage solutions with proper security allow authorized access from multiple locations. API connectivity enables healthcare organizations to integrate form data with other systems. Accessible form design accommodates patients with disabilities or language barriers to ensure equal access to privacy protections.
Form Data Management and Integration
Healthcare organizations need systems to manage form data securely after collection. HIPAA compliant forms integrate with secure email systems for protected transmission of patient information. Data from forms flows into relevant clinical and business systems without compromising security. Integration with customer relationship management and patient journey tracking helps organizations provide cohesive care experiences. Marketing automation tools can use non-PHI form data for appropriate patient outreach while protecting sensitive information. Clear data retention policies comply with HIPAA requirements while supporting operational needs. Documented data flows from forms to downstream systems maintain compliance throughout the information lifecycle.
HIPAA Form Compliance Monitoring
Healthcare organizations maintain monitoring systems to ensure form compliance over time. Regular audits identify potential privacy violations or security weaknesses in form collection processes. Staff training covers form handling procedures and includes updates when regulations change. Form review schedules keep all documents current with changing requirements. Monitoring tracks form completion rates to identify process issues affecting patient care. Organizations maintain documentation of form versions, approval dates, and modification histories. Security teams regularly test technical protections for electronic forms to verify continued effectiveness. Compliance officers review form-related complaints to identify improvement opportunities.
Have you looked into what it’s costing your company to snail mail EOBs these days?
EOBs give an individual an increased understanding of their insurance coverage, the cost of care, and their out of pocket expenses. As a result, it’s absolutely critical that health insurers deliver EOBs quickly and effectively.
However, the most commonly used method for sending out EOBs, traditional mail or snail mail, has several drawbacks that can prevent important information about healthcare coverage from reaching people in a timely manner – not to mention the high cost insurers take on to send them. This can leave policyholders in the dark about their healthcare coverage, which can lead to confusion and dissatisfaction with their insurance provider when they receive an unexpected medical bill.
Furthermore, because EOBs contain the protected health information (PHI) of policyholders or members, insurers are bound by HIPAA (the Health Insurance Portability and Accountability Act) regulations to ensure their secure delivery. Consequently, the risks inherent to sending paper EOB statements in the mail not only have security implications but also potential consequences for non-compliance.
With all this in mind, this post discusses why healthcare insurers should send EOBs to their policyholders via secure email instead of traditional mail. We detail the various benefits of making the switch to email EOBs, which include enhanced security, better adherence to compliance regulations, higher deliverability rates, and significant cost savings.
Security Benefits
Insurance companies that send out EOBs via email as opposed to traditional mail are less likely to be at risk for a data breach or leak of PHI. Firstly, sending an EOB via email drastically decreases the risk of interception. When sent in paper form, an EOB could be:
Lost, stolen or damaged in transit
Delivered to the wrong address
Not properly deposited in a letter or mailbox, then stolen
Intercepted within the intended address by another individual who lives at or has access to the residence.
Conversely, as detailed later in this post, email allows for various controls and processes, which mitigate the risks of unsuccessful message delivery.
Additionally, secure, HIPAA compliant email provides data encryption, which safeguards the sensitive patient data within EOBs during transmission and at rest by rendering it unreadable to malicious actors who might intercept it or gain access to it. Physical mail, in contrast, offers no such protection, as someone who intercepts a paper EOB notice can simply open it and freely read its contents.
Finally, secure email delivery platforms, such as LuxSci, feature identity verification and access controls that enable healthcare insurers to restrict access to PHI, limiting its exposure. Similarly, HIPAA compliant email also provides auditing logging capabilities to track access to patient data, to quickly identify the source of security breaches.
Increased Delivery
Once a person opts-in, sending an EOB by email greatly increases its deliverability, up to 98% or more – almost instantly. By better ensuring a policyholder receives their EOBs, healthcare insurers increase the chance of successfully communicating the intended information they contain, namely, the cost of a service and how much they’re required to cover.
Additionally, the ability to track secure email in near real-time also enhances its deliverability, as it allows organizations to determine the cause of delivery failure and make subsequent attempts to get the EOB delivered. At the same time, the process of determining the reason for the message failure may also reveal security concerns; a process that is very difficult, if not impossible, to achieve with traditional physical mail.
Radical Cost Savings
Simply put, sending EOBs via email instead of traditional mail can save health insurers massive amounts of money. By saving a dollar or more per EOB, the cost savings can quickly add up to millions of dollars per month in savings.

The most significant cost reduction is the money saved on printing and mailing paper EOB statements. Additionally, the cost of administering the delivery of EOB notices is lowered when it’s done electronically. Resending EOBs in the event of their non-delivery also is much easier, faster and cheaper via email.
Compliance Benefits
Because sending an EOB via email requires HIPAA compliance, your communications are encrypted by default, protecting patient privacy and keeping PHI out of the hands of malicious actors, all while reducing the risk of HIPAA compliance violations. The security features built into HIPAA compliant email platforms, such as encryption, access control, and audit logs, help insurers satisfy the requirements of HIPAA’s Privacy and Security Rules in their compliance efforts.
Another considerable benefit of using secure email to send policyholders their EoBs, or, in fact, any communication containing PHI, is that it’s far easier to implement breach notification protocols. HIPAA compliant email delivery platforms provide real-time tracking, so companies can pinpoint email message failures quickly and act accordingly. Similarly, intrusion detection systems and other cybersecurity measures that support email systems enable the faster detection and containment of data breaches.
In stark contrast, physical mail is far more difficult to track. Consequently, security breaches via mail could go unnoticed for days or even weeks. If you’re unaware of a data breach, let alone have not yet contained or mitigated it, you’re unable to inform all affected parties, resulting in further HIPAA violations and a loss of customer trust.
Reduced Carbon Footprint
It’s difficult to highlight the cost benefits of sending EOBs to policyholders by email without recognizing the positive environmental impact, too. Email EOBs cuts down on paper usage, for both the notices themselves and the envelopes they’re mailed in. Then there’s the matter of the electricity and ink involved in printing them, the emissions produced in their delivery, etc. Opting to send EOBs via email reduces all these factors, which enables healthcare organizations to lower their carbon footprint and, where applicable, meet their sustainability obligations.

Microsoft Outlook is one of the most widely used email platforms, including in healthcare, but is it truly HIPAA-compliant? The answer isn’t straightforward. While Outlook, and the entire Microsoft 365 application suite, offer security features that can support HIPAA compliance, they are not inherently compliant out of the box.
Healthcare organizations must actually take additional measures to ensure they meet HIPAA’s stringent requirements before they can transmit electronic protected health information (ePHI) in their email communications – without risking the consequences of non-compliance.
With this in mind, this post examines Microsoft 365 and Microsoft Outlook’s security capabilities, where and how they fall short of compliance standards, and, subsequently, how to secure each application in accordance with HIPAA regulations.
Understanding HIPAA Compliant Email Requirements
HIPAA compliant email requires healthcare organizations to implement a series of technical, administrative, and physical safeguards to protect the sensitive patient data that they’ve amassed during the course of their operations – and are legally obliged to secure it in transit and at rest. Taking a brief look at each category in turn, these safeguards include:
Technical
Encryption: converting ePHI into an unreadable format.
Accesscontrols: ensuring only authorized personnel can access patient data.
Auditlogs: tracking who has accessed ePHI and what they did with it.
Administrative
Risk assessments: identifying and categorizing risks to ePHI and implementing mitigation measures.
Workforce training: educating employees, especially those who handle ePHI, on how to identify cyber threats, e.g, phishing, and how to respond.
Business Associate Agreements (BAAs): a required document for HIPAA compliance that outlines each party’s responsibility and liability in protecting patient data.
Physical safeguards:
Securing servers: preventing access to the servers on which ePHI resides.
Restricting device access: implementing measures to keep malicious actors from accessing employee devices, should one fall into their hands.
Implementing screen locks: a simple, yet effective, form of device access control is setting them to lock after a few seconds of inactivity.
What Security Features Do Microsoft 365 and Microsoft Outlook Have?
Before detailing how Microsoft 365 and Microsoft Outlook do not meet HIPAA’s standards by default, let’s look at its security features:
1. Encryption and Data Protection
Microsoft 365 offers several encryption options, including:
TLS: Transport Layer Security (TLS) secures email in transit but does not encrypt emails at rest; if a recipient’s email server does not support TLS, messages may be sent in plaintext.
Office Message Encryption (OME): Office Message Encryption (OME) allows users to send encrypted messages, but it requires recipients to log in to a Microsoft account or use a one-time passcode. OME integrates with Microsoft 365’s Purview Message Encryption feature, which incorporates encryption, Do Not Forward, and rights management.
BitLocker Encryption: Encrypts data at rest within Microsoft’s cloud infrastructure.
Azure Information Protection: a cloud-based solution that allows users to classify, label, and protect data based on its sensitivity.
While these encryption methods provide some security, they lack the flexibility and automation needed to ensure consistent HIPAA compliance, especially for high-volume email campaigns.
2. Access Controls & Authentication
Microsoft 365 and Microsoft Outlook include access controls, such as role-based permissions and device management policies, and user authentication measures such as Multi-Factor Authentication (MFA). However, organizations must actively manage and enforce these policies to prevent breaches.
3. Audit Logging & Compliance Reporting
Microsoft provides audit logging and reporting tools via the Microsoft Purview Compliance Portal. These logs help organizations track access to ePHI, but proper configuration is required to ensure that HIPAA-required retention policies are met.
4. Business Associate Agreement
One of the distinguishing features of using Microsoft 365 and Microsoft Outlook is that the company will sign a Business Associate Agreement (BAA) with healthcare organizations. However, the Microsoft BAA only applies to specific Microsoft 365 services that meet HIPAA requirements, such as Outlook, Exchange Online, and OneDrive – while apps like Skype may not be covered.
This means healthcare organizations must carefully configure Microsoft 365 to use only HIPAA-covered services and apply security controls like encryption, access restrictions, and audit logging.
How Microsoft Outlook and Microsoft 365 Fall Short of HIPAA Regulations
Despite Microsoft 365 and Outlook’s comprehensive security features, out of the box, they still lack a series of capabilities and configurations that prevent them from being fully HIPAA-compliant.
No End-to-End Encryption: TLS protects emails in transit, but messages may be readable on recipient servers if they don’t support TLS, exposing ePHI.
Lack of Automatic Encryption: Microsoft 365 requires users to manually apply encryption settings for emails containing sensitive data, increasing the risk of human error and falling victim to data breaches.
Key management issues: healthcare organizations must rely on Microsoft’s encryption key management, rather than maintaining full control over their own keys.
Lack of recipient flexibility: OME requires recipients to authenticate via Microsoft accounts, which can be cumbersome for patients and other third-parties.
Limited DLP Enforcement: Outlook’s default settings don’t prevent ePHI from being sent unencrypted without proper data loss prevention (DLP) rules.
Audit Logging Gaps: while Microsoft 365 logs activity, they must be reviewed and retained properly to meet HIPAA guidelines.
To bridge these security gaps, healthcare organizations need an additional layer of protection.
In short, Microsoft 365 and Microsoft Outlook are not HIPAA-compliant out of the box, and healthcare companies should fully understand the implications and steps needed before using them for HIPAA compliant email communications and campaigns. However, unlike other leading email platforms, such as Mailchimp and SendGrid, they can be made HIPAA-compliant.
