Authentication Gets a Major Upgrade
With the latest API release, LuxSci now supports three industry-standard authentication methods—alongside its proprietary LuxSci Secure option.
Let’s break them down:
OAuth 2.0 – The modern standard. Secure, flexible, and ideal for enterprise-scale integrations.
API Key – Simple and efficient. Ideal for server-to-server use when convenience matters most.
Basic Authentication – Straightforward and widely supported. Great for internal systems and quick testing.
Still Available and Highly Recommended: LuxSci Secure Authentication
For those who want the tightest possible control over API sessions—including HMAC signatures and session revocation—LuxSci Secure authentication remains the best option for customers.
Now, let’s take a closer look at how each of the new authentication methods work:
OAuth 2.0: A Standards-Based Approach
OAuth 2.0 gives you a robust framework to handle both account-level and user-level integrations.
This method allows API access on behalf of individual users—great for patient portals or provider tools.
Security, Flexibility, and Simplicity Combined
Tokens expire after a default of 15 minutes, ensuring sessions aren’t left open indefinitely. Bonus: No message body signing is required, making integration quick and painless.
API Key: Simple and Straightforward
API Key authentication is as easy as including your credentials in a custom header. No session to manage, no extra handshake steps.
How It Works:
You send the HTTP header
X-API-Key: client_id:client_secret
With each request. That’s it.
Ideal Use Cases
Server-to-server automation
Internal dashboards
Data exports from analytics platforms
Basic Authentication: Familiar and Easy
Basic Auth is a time-tested option. Just Base64 encode your API credentials, include them in an HTTP header, and go.
While not as bulletproof as OAuth or LuxSci Secure, API Key and Basic Auth work fine for less sensitive data or development environments.
Easy Access to YAML Specs and SwaggerHub for API Testing
LuxSci has also published detailed YAML API specifications, making it easier for developers and IT teams to access testing interfaces.
You can find more information on our LuxSci API page.
Improved MFA and Easier Access to Testing Tools
As part of today’s announcement, LuxSci also rolled out new, smarter Multi-Factor Authentication (MFA) for enhanced web interface login protection.
LuxSci now ensures that each MFA code can be used only once. So, even if a hacker captures your password and MFA code, they are useless for conducting new login sessions. This update helps protect against automated phishing, spoofing, and fake login pages.

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.

PHI email becomes compliant through end-to-end encryption, access controls, audit trails, and secure transmission protocols. Healthcare organizations must implement email solutions that encrypt protected health information both in transit and at rest, maintain detailed logs of all communications, and restrict access to authorized personnel only. Medical practices encounter the challenges of patient information travelling through digital communication channels, as each message contains names, medical record numbers, or treatment details. Patient communications flow through healthcare systems constantly, creating numerous opportunities for data exposure. Email messages containing appointment confirmations, lab results, or billing inquiries must receive the same protection level as paper records stored in locked cabinets. The difficulty increases when metadata reveals patient-provider relationships without obvious identifying information appearing in message content itself.
Email Encryption Methods Protect Patient Data
Healthcare email platforms deploy Advanced Encryption Standard protocols with 256-bit keys to render intercepted messages unreadable without proper decryption credentials. Transport Layer Security protocols shield communications during transmission between mail servers, while storage encryption protects messages residing in email systems. These protection layers work to secure PHI email whether traveling across networks or sitting in user mailboxes.
Identity-based encryption provides an alternative where recipients authenticate through secure web portals instead of managing encrypted attachments with complex passwords. Patients log into portal systems once and access their messages without downloading files or remembering multiple authentication credentials for different healthcare providers.
User Access Controls Prevent Information Breaches
Multi-factor authentication requires users to provide passwords, mobile verification codes, and sometimes biometric data before accessing PHI email systems. Staff members receive permissions aligned with their job responsibilities, preventing billing personnel from reading clinical notes while restricting nurses from accessing financial communications. These permission structures eliminate accidental information exposure between healthcare departments.
Session timeouts automatically disconnect users after inactivity periods, and systems monitor failed login attempts to detect potential unauthorized access. Organizations document access permissions and conduct monthly reviews to ensure appropriate information boundaries. Employee departures trigger immediate email access revocation to prevent data exposure after employment ends.
Monitoring Systems Track Message Activities
Modern PHI email platforms record message creation, transmission, delivery, viewing, forwarding, and deletion activities. These logs include timestamps, user identifications, and recipient information that create detailed records for compliance reviews and incident investigations. Healthcare organizations must preserve these records for six years and provide them during HIPAA audits.
Behavioral analysis systems detect unusual patterns like mass message downloads during off-hours or attempts to redirect communications to personal email accounts. Security teams receive immediate notifications when suspicious activities occur, enabling rapid investigation of potential breaches or unauthorized access attempts.
Vendor Contracts Define Compliance Obligations
Email service providers handling patient information must execute business associate agreements outlining their compliance responsibilities. These contracts address data protection standards, breach notification timelines, and audit cooperation requirements. Cloud email providers must prove their systems meet HIPAA standards through independent security assessments.
Healthcare organizations bear liability for vendor compliance failures, making thorough evaluation processes necessary before selecting email platforms. Assessment procedures examine data storage locations, infrastructure security measures, and incident response capabilities to ensure adequate protection throughout the technology supply chain.
Employee Education Prevents Security Violations
Training programs teach staff to identify phishing attempts, follow acceptable use policies, and handle PHI email appropriately. Organizations conduct simulated phishing exercises to evaluate employee responses to suspicious messages and provide additional education for those requiring improvement. Policies clarify when staff should use secure messaging platforms instead of traditional email systems.
Content filtering systems scan outgoing messages for Social Security numbers, medical record numbers, and other patient identifiers. When these systems detect sensitive information, they automatically apply encryption or prevent message transmission until users implement appropriate security measures.
Performance Tracking Ensures Program Effectiveness
Healthcare organizations monitor encryption usage rates, policy compliance scores, and incident response times to evaluate their PHI email programs. Monthly assessments examine compliance trends and identify areas where system improvements or additional training could strengthen protection. Risk evaluations examine emerging threats and technology changes that might affect email security.
Compliance teams review email policies quarterly and update procedures based on regulatory developments or security incidents. System testing verifies that encryption, access controls, and monitoring functions operate correctly under various usage conditions, ensuring patient communications receive consistent protection through all organizational email activities.
Fixing email not delivered issues requires healthcare organizations to verify email addresses, implement authentication protocols, reduce spam triggers, and maintain clean communication channels to ensure messages reach their intended recipients. When an email is not delivered, it triggers communication failures that can disrupt patient care, delay treatments, and create operational inefficiencies throughout healthcare systems. An email not delivered means the intended recipient never receives the message, whether due to spam filtering, server issues, authentication problems, or incorrect email addresses. Healthcare providers, payers, and suppliers experience immediate consequences when critical communications fail to reach their destinations, including missed appointments, delayed care coordination, and lost revenue opportunities. The impact of an email not delivered varies depending on the message type, recipient, and timing, but healthcare organizations consistently see negative effects on patient outcomes and operational performance.
Recovery Strategies For an Email Not Delivered
Recovery strategies after an email not delivered include implementing backup communication methods and improving email authentication protocols. Healthcare organizations can reduce the impact of delivery failures by maintaining multiple contact methods for patients and developing contingency plans for communication disruptions. Regular monitoring of email delivery metrics helps identify patterns of failed deliveries and address underlying causes. Proactive list management and sender reputation monitoring help prevent future instances of email not delivered. Healthcare organizations benefit from establishing dedicated resources for managing email communications, including staff training on delivery best practices and ongoing performance monitoring across different communication channels. These recovery strategies help minimize the long-term impact of email delivery failures on patient care and operational efficiency.
Immediate Consequences
The immediate consequences when an email is not delivered include broken communication chains and missed opportunities for patient engagement. Appointment reminders that fail to reach patients result in higher no-show rates, while lab results trapped in spam folders delay treatment decisions. Healthcare staff may not realize that an email not delivered has occurred until patients miss appointments or fail to respond to time-sensitive communications. Patient portal notifications that go undelivered prevent patients from accessing test results, prescription refills, and discharge instructions. Emergency contact attempts via email may fail when an email not delivered occurs during after-hours situations, forcing healthcare providers to rely on phone calls or postal mail as backup communication methods. These immediate failures create workflow disruptions that require additional staff time and resources to resolve.
Patient Care Disruptions When Email is Not Delivered
Patient care disruptions occur when an email not delivered prevents timely communication between healthcare providers and patients. Referral communications that never arrive can interrupt care coordination between primary physicians and specialists, delaying diagnoses and treatment plans. Pre-operative instructions sent via email may not reach patients, creating safety risks and potential surgical delays. Chronic disease management programs rely heavily on email communication for medication reminders, lifestyle coaching, and progress monitoring. When an email not delivered occurs in these programs, patients may miss medication doses, skip monitoring activities, or fail to attend follow-up appointments. Medication adherence drops significantly when patients do not receive email reminders about prescription refills or dosage changes.
Revenue Impact
Revenue impact from an email not delivered includes lost appointment fees, delayed payments, and reduced patient engagement with healthcare services. Billing statements that fail to reach patients extend collection cycles and increase accounts receivable aging. Insurance pre-authorization requests that go undelivered can delay procedures and reduce reimbursement opportunities. Healthcare organizations lose revenue when marketing emails promoting wellness programs, health screenings, and elective procedures fail to reach patient inboxes. Patient satisfaction scores may decline when communication failures occur, affecting quality bonuses and value-based care payments. The financial impact compounds over time as organizations continue investing in email communication tools that fail to deliver expected returns due to delivery failures.
Operational Inefficiencies from Email Not Delivered
Operational inefficiencies arise when an email not delivered disrupts routine workflows and communication processes. Staff members spend additional time following up on communications that may have been filtered or blocked, reducing productivity and increasing administrative costs. Supply chain communications that fail to reach vendors or suppliers can create inventory shortages and delivery delays. Electronic health record systems generate automated notifications for various clinical events, and when an email not delivered occurs, providers may miss important alerts about patient status changes or test results. Quality improvement initiatives that depend on email communication for data collection and reporting may experience delays when key stakeholders do not receive project updates or meeting notifications.
Technology System Failures
Technology system failures occur when an email not delivered prevents automated notifications from reaching their intended recipients. Practice management software relies on email alerts for appointment scheduling, billing processes, and patient communication workflows. When these notifications fail to deliver, healthcare organizations may experience system-wide communication breakdowns affecting multiple departments. Telemedicine platforms and health information exchanges depend on email notifications to alert providers about new patient data, consultation requests, and system updates. An email not delivered in these systems can prevent providers from accessing important patient information or responding to urgent consultation requests. Integration failures between healthcare applications may occur when email-based data exchange processes fail to complete successfully.
Email is an essential channel for most healthcare marketers, but HIPAA compliance requirements can make it challenging to execute effective engagement campaigns without violating patient privacy.
HIPAA is a complicated set of regulations that while offering a lot of guidance, does not mandate the use of any specific technologies to protect patient privacy. This ambiguity causes a lot of confusion for marketers looking to integrate email into their healthcare engagement campaigns.
With this in mind, this article addresses some frequently asked questions (FAQs) about HIPAA-compliant email marketing and offers advice for securing patient data and future-proofing your marketing.
Some marketers assume newsletters from a healthcare provider or supplier do not contain health information and, therefore, do not fall under HIPAA requirements. This assumption, however, is often incorrect, with many surprised to learn that protected health information (PHI) can be implied from seemingly innocuous information.
As a result, many generic email newsletters often indirectly contain PHI due to the very fact that they are sent to lists of current patients or customers. This is because email addresses count as individually identifiable data and when combined with the message therein, it’s pretty simple to infer that they are patients or customers.
Let’s say, for example, that you send a newsletter to the patients of a dialysis clinic. An eavesdropper could infer that the recipients receive dialysis. Consequently, as the email reveals information about an individual’s health treatment, it contains PHI and should be secured in compliance with HIPAA regulations.
For the fundamental reason that it can be difficult to determine what classifies as PHI, it’s safer to skip the ambiguity entirely and use a HIPAA-compliant email marketing solution to ensure security.
What is an email API?
An Application Programming Interface (API) is a collection of protocols, or rules, that enable different applications to communicate with each other. APIs are a crucial aspect of modern applications – as they spare developers the considerable effort of creating application features from scratch – they can just connect to the API of an existing application.
For example, how many websites have you used that utilize Google Maps? This is because they have connected their site to the Google Maps API – integrating it into their application and providing another feature for their users.
In the case of an email API, it is a way for applications, such as customer relationship management (CRM) platforms, customer data platforms (CDP) and electronic health record (EHR) systems, to connect to email service providers. This then allows marketers to send emails through the application, using the ePHI (electronic protected health information) collected and stored within the application.
Additionally, marketers can view and further utilize campaign data through the powerful dashboards and analysis tools found in CRM systems and similar applications. Trigger-based transactional or marketing emails are ideal for sending with an email API, whereby emails are sent when pre-determined conditions in the application are met. Healthcare organizations may use email APIs to send appointment reminders using electronic health records system data about a patient’s upcoming appointments, check ups or treatments.
As invaluable as email APIs are, however, especially for streamlining and automation communication workflows, they are no substitute for a comprehensive email marketing platform. Email APIs do not include the contact management systems standard in most email marketing platforms, as all the data resides within the application they connect to. Additionally, email API tools do not typically include drag-and-drop editor tools and other design features that enable you to make your emails stand out and boost patient engagement.
Does HIPAA allow healthcare providers and companies to send unencrypted emails with PHI to patients?
Encryption is an addressable standard, i.e., it must be implemented by the organization unless a risk analysis concludes that implementation is not reasonable and appropriate, under the HIPAA Security Rule. This does not mean it is optional. The HIPAA Security Rule does not explicitly forbid unencrypted email. Still, it does state that “other safeguards should be applied to protect privacy reasonably, such as limiting the amount or type of information disclosed through the unencrypted email.”
In addition, the Department of Health and Human Services also states that “covered entities are permitted to send individuals unencrypted emails if they have advised the individual of the risk, and the individual still prefers the unencrypted email.” in response to this, some organizations use waivers to inform patients of the risks and acquire permission to send unencrypted emails.
However, we do not recommend this approach for several reasons:
Keeping track of waivers over time and recording status changes and updates is challenging – and increases your administrative overhead.
Signed waivers do not insulate you from the consequences of a HIPAA breach.
Using waivers to send unencrypted emails doesn’t absolve you of your other HIPAA obligations, such as data retention and disposal. Subsequently, using a HIPAA-compliant email solution is more manageable and eliminates ambiguity.
Can patients exercise their right of access of receiving PHI voa unencrypted email?
Yes, but they must be fully informed of the risks and sign waivers acknowledging them; the caveats detailed in the above answer apply. Consequently, it’s always best to use an encryption tool to protect patient data.
Is Microsoft 365 with encryption sufficient for sending marketing emails?
Microsoft 365 can be configured with Office Message Encryption (OME) to comply with HIPAA. However, it is not well-suited for sending marketing emails. OME primarily relies on portal pickup encryption, in which the message is stored securely on a server and requires the recipient to log in to the portal to read the email. As a result, the portal adds friction to the marketing process that prevents optimal engagement and constrains ROI.
Marketing messages containing light-PHI, i.e. low-risk data, are best sent using Transport Layer Security (TLS) encryption. TLS-encrypted messages arrive in the recipient’s inbox just like a regular email and do not require them to complete an additional step.
Additionally, Microsoft 365 is not configured to send high volumes of email. If you plan on executing large scale marketing campaigns, you could unintentionally disrupt regular business communications by sending all the messages through the same infrastructure. Instead, you should separate your business and marketing email delivery activities to protect your IP reputation, i.e., the trustworthiness of your IP addresses and how likely it is your emails end up in a spam folder, and achieve your desired sending throughput.
What are the common email marketing use cases for healthcare?
Email marketing in healthcare is not restricted to boring general practice newsletters and other communications that fail to engage patients. When you successfully harness tools that enable you to use ePHI to better target and personalize your healthcare engagement campaigns – the sky is the limit. With consumer preferences shifting toward digital communications, marketers who know how to best utilize HIPAA-compliant email marketing – and tactics like segmentation and personalization – will prove more effective at reaching patients.
Examples of ways that healthcare marketers can use email include:
Lead generation campaigns
Promotions
Verifications
Order confirmations
Notifications
Upsell & cross-sell
Collecting data on the patient experience
How do I find a HIPAA-compliant email vendor?
Using popular email marketing platforms, such as Mailchimp, is not recommended. Many of these platforms were designed for businesses, but are simply not secure enough to meet HIPAA requirements. We do not recommend using a solution not specifically equipped to meet the healthcare industry’s unique security and compliance needs. To determine if your email marketing provider is compliant, they must meet three broad criteria at a minimum.
The vendor must sign a Business Associate Agreement (BAA) outlining how they plan to secure your data and what they will do in the event of a breach.
Encrypt data at rest when it is stored in their systems.
Encrypt data, i.e., email messages, in transit as sent to the recipients.
Not all vendors will be up to the task. Carefully vet your email marketing vendors to ensure they are taking steps to secure data and protect patient privacy.

Are you up to date on the latest email security threats?
In this post, we share details from our just-released Email Cyber Threat Readiness Report, exploring the most effective ways to strengthen your healthcare organization’s email cyber threat readiness in 2025.
Let’s go!
Conduct Regular Risk Assessments
To strengthen your company’s email security posture, you must first identify vulnerabilities in your infrastructure that malicious actors could exploit. Frequent risk assessments will highlight the security gaps in your email infrastructure and allow you to implement the appropriate strategies to mitigate threats.
A comprehensive email risk assessment should include:
Assessment of email encryption practices.
Review of email authentication protocols, i.e., SPF, DKIM, DMARC.
Evaluation of access control policies and practices.
Assessment of malware detection capabilities.
Audit of third-party integrations.
Testing of employee email threat awareness through simulated attacks to determine threat readiness and training needs.
Review of incident response and business continuity plans, especially, in this case, in regard to email-based threats.
A risk assessment may also involve the use of vulnerability scanning tools, which scan your email infrastructure looking for conditions that match those stored in a database of known security flaws, or Common Vulnerabilities and Exposures (CVEs). Alternatively, healthcare companies often employ the services of ethical, or ‘white hat’, hackers who carry out penetration tests, in which they purposely attempt to breach your email security measures to pinpoint its flaws.
Implement Email Authentication Protocols
As touched on above, enabling and correctly configuring the right email authentication protocols is an essential mitigation measure against phishing and BEC attacks, domain spoofing and impersonation, and other increasingly common email threats. Just as importantly, it allows recipient email servers to verify that a message is authentic and originated from your servers, which reduces the risk of your domain being blacklisted and your emails being directed to spam folders instead of the intended recipient’s inbox.
The three main email authentication protocols are:
DomainKeys Identified Mail (DKIM): adds a cryptographic signature to outgoing emails, allowing the recipient’s server to verify that the email was not altered in transit.
Sender Policy Framework (SPF): allows domain owners to specify which servers are authorized to send emails on their behalf, mitigating domain spoofing and other forms of impersonation.
Domain-based Message Authentication, Reporting & Conformance (DMARC): builds on SPF and DKIM by establishing policies for handling unauthorized emails. It instructs the recipient email server to monitor, quarantine, or reject emails that fail authentication checks.
Establish Robust Access Control Policies
Implementing comprehensive access control policies reduces the chances of ePHI exposure by restricting its access to individuals authorized to handle it. Additionally, access privileges shouldn’t be equal and should be granted based on the employee’s job requirements, i.e., role-based access control (RBAC).
Zero Trust Architecture (ZTA), in contrast, is a rapidly emerging, and more secure, alternative to RBAC. ZTA’s core principles are “least privilege”, i.e., only granting the minimum necessary access rights, and “never trust, always verify”, i.e., continually asking for the user to confirm their identity as the conditions of their session change, e.g., their location, the resources they request access to, etc.
Enable User Authentication Measures
Because a user’s login credentials can be compromised, through a phishing attack or session hijacking, for instance, access control, though vital, only protects ePHI to an extent. Subsequently, you must require a user to prove their identity, through a variety of authentication measures – with a common method being multi-factor authentication (MFA).
Recommended by HIPAA, MFA requires users to verify their identity in two or more ways, which could include:
Something they know (e.g., one-time password (OTP), security questions)
Something they have (e.g., a keycard or security token)
Something they are (i.e., biometrics: retinal scans, fingerprints, etc.).
What’s more, it’s important to note that the need to enable MFA will be emphasized to a greater degree when the proposed changes to the HIPAA Security Rule go into effect in late 2025.
Identify and Manage Supply Chain Risk
While on the subject of access control, one of the most significant security concerns faced by healthcare organizations is that several third-party organizations, such as vendors and supply chain partners, have access to the patient data under their care to various degrees. As a result, cybercriminals don’t have to breach your email security measures to access ePHI – they could get their hands on your patients’ data through your vendors.
Consequently, third-party risk management must be a fundamental part of every healthcare organization‘s email threat mitigation strategy. This requires you to ensure that each vendor you work with has strong email security measures in place. In light of this, a HIPAA requirement is to have a business associate agreement (BAA) in place with each third party, or business associate, so you both formally establish your responsibilities in securing ePHI.
Set Up Encryption for Data In Transit and At Rest
Encrypting the patient data contained in email communication is a HIPAA regulation, as it prevents its exposure in the event of its interception by a cybercriminal. You should encrypt ePHI both in transit, i.e., when being included in emails, and at rest, i.e., when stored in a database.
Encryption standards sufficient for HIPAA compliance include:
TLS (1.2 +): a commonly-used encryption protocol that secures email in transit; popular due to being ‘invisible’, i.e., simple to use.
AES-256: a powerful encryption standard primarily used to safeguard stored data, e.g., emails stored in databases or archives.
PGP: uses public and private key pairs to encrypt and digitally sign emails for end-to-end security.
S/MIME: encrypts and signs emails using digital certificates issued by trusted authorities.
Develop a Patch Management Strategy
One of the most common means of infiltrating company networks, or attack vectors, is exploiting known security vulnerabilities in applications and hardware. Vendors release updates and patches to fix these vulnerabilities, so it’s crucial to establish a routine for regularly updating and patching email delivery platforms and the systems and infrastructure that underpin them.
Additionally, vendors periodically stop supporting particular versions of their applications or hardware, leaving them more susceptible to security breaches. With this in mind, you must track which elements of your IT ecosystem are nearing their end-of-support (EOS) date and replace them with suitable, HIPAA-compliant alternatives.
Implement Continuous Monitoring Protocols
Continuously monitoring your IT infrastructure is crucial for remaining aware of suspicious activity in your email traffic and potential security breaches. Without continuous monitoring, cybercriminals have a prime opportunity to infiltrate your network between periodic risk assessments.
Worse, they can remain undetected for longer periods, allowing them to move laterally within your network and access your most critical data and systems. Conversely, continuous monitoring solutions employ anomaly detection to identify suspicious behavior, unusual login locations, etc.
Develop Business Continuity and Disaster Recovery Plans
The unfortunate combination of organizations being so reliant upon email communication, email threats being so prevalent, and the healthcare sector being a consistent target for cyber attacks makes a data breach a near inevitability rather than a mere possibility.
Consequently, it’s imperative to develop business continuity and disaster recovery protocols so you can resume normal operations as soon as possible in the event of a cyber attack. An essential part of a disaster recovery plan is making regular data backups, minimizing the impact on the service provided to patients and customers.
Implement Email Threat Awareness Training for Employees
Healthcare organizations must invest in email threat awareness training for their employees, so they can recognize the variety of email-based cyber attacks they’re likely to face and can play a role in their mitigation.
Email threat awareness training should include:
The different email-based cyber threats (e.g., phishing), how they work, and how to avoid them, including AI-powered threats.
Who to inform of suspicious activity, i.e., incident response procedures.
Your disaster recovery protocols.
Cyber attack simulations, e.g., a phishing attack or malware download.
While educating your employees will increase their email threat readiness, failing to equip them with the knowledge and skills to recognize email-based attacks could undermine your other mitigation efforts.
