What Is HIPAA Compliant Email Encryption?

HIPAA Email Encryption
Erik Kangas
April 1, 2025

HIPAA compliant email encryption protects protected health information (PHI) during electronic transmission by converting readable data into coded format that only authorized recipients can decode. This encryption method meets HIPAA Security Rule requirements for protecting electronic PHI in transit and helps healthcare organizations maintain compliance when communicating patient information via email. Healthcare organizations accumulate pressure to secure patient communications while maintaining operational efficiency. Email is the backbone of healthcare communication, yet standard email transmission leaves PHI vulnerable to interception and unauthorized access.

How HIPAA Compliant Email Encryption Functions

HIPAA Email encryption transforms plain text messages containing PHI into unreadable code during transmission. The process uses mathematical algorithms to scramble data, making it accessible only to recipients who possess the correct decryption key. When healthcare providers send encrypted emails, the message travels through internet infrastructure in protected form, preventing unauthorized parties from reading PHI even if they intercept the communication. Most HIPAA compliant email encryption uses two main methods: Transport Layer Security (TLS) and end-to-end encryption. TLS creates a secure tunnel between email servers, protecting messages during transit. End-to-end encryption goes further by encrypting messages on the sender’s device and decrypting them only on the recipient’s device, ensuring even email service providers cannot access the content.

The encryption process happens automatically in most healthcare-grade email systems. Users compose messages normally, but the system applies encryption protocols before transmission. Recipients receive encrypted messages through secure portals or their own encrypted email clients, where proper authentication allows access to the original content.

Legal Requirements Under HIPAA Security Rule

The HIPAA Security Rule mandates protections for electronic PHI, including email communications. Organizations must implement addressable transmission security standards that protect PHI from unauthorized access during electronic transmission. While HIPAA does not explicitly require encryption, the regulation demands “reasonable and appropriate” safeguards for ePHI transmission.Healthcare entities must conduct risk assessments to determine appropriate security measures for their email communications. When risk analysis reveals vulnerabilities in email transmission, encryption helps meet HIPAA compliance standards. Organizations that choose not to implement encryption must document alternative safeguards that provide equivalent protection for PHI.

Business associate agreements play an important role in HIPAA compliant email encryption requirements. When healthcare organizations use third-party email services, these vendors must sign business associate agreements and implement appropriate security measures. The agreements must outline how the vendor will protect PHI and maintain HIPAA compliance standards.

Authentication Methods for Secure Access

HIPAA compliant email encryption relies on strong authentication mechanisms to verify recipient identity before granting access to encrypted messages. Multi-factor authentication has become the gold standard, requiring users to provide multiple verification forms such as passwords, SMS codes, or biometric data before accessing encrypted communications.Digital certificates provide another layer of authentication in encrypted email systems. These certificates verify the sender’s identity and ensure message integrity during transmission. Recipients can confirm that messages originated from legitimate healthcare providers and have not been tampered with during delivery.

Some encrypted email systems use secure web portals for message access. Recipients receive notification emails directing them to protected portals where they must authenticate their identity before viewing encrypted content. This method allows healthcare organizations to maintain control over PHI access even when communicating with external parties who may not have encrypted email capabilities.

Integration with Existing Healthcare Systems

Healthcare organizations require HIPAA compliant email encryption solutions that integrate seamlessly with their current technology infrastructure. Modern encryption platforms connect with electronic health record systems, practice management software, and other healthcare applications to streamline encrypted communication workflows.API integrations allow healthcare applications to send encrypted notifications and reports automatically. For example, laboratory systems can generate encrypted emails containing test results and send them directly to ordering physicians without manual intervention. This automation reduces the risk of human error while maintaining HIPAA compliance throughout the communication process.

Mobile device compatibility has grown in importance as healthcare professionals rely on smartphones and tablets for patient care. HIPAA compliant email encryption must function across various devices and operating systems while maintaining security standards. Mobile encryption apps often include features like remote wipe capabilities to protect PHI if devices are lost or stolen.

Cost Considerations for Healthcare Organizations

Implementing HIPAA compliant email encryption involves various cost factors that healthcare organizations must evaluate. Setup costs include software licensing, system integration, and staff training expenses. Ongoing costs encompass monthly or annual subscription fees, maintenance, and support services from encryption vendors. The financial impact of HIPAA violations often exceeds encryption implementation costs by large margins. Recent HIPAA enforcement actions have resulted in monetary penalties ranging from thousands to millions of dollars, depending on violation severity and organizational size. These potential fines make encryption implementation a cost-effective investment in long-term compliance protection.

Return on investment calculations should include improved operational efficiency from streamlined secure communications. Encrypted email systems often reduce time spent on manual PHI handling processes and eliminate the need for alternative communication methods like fax machines or physical mail for sensitive information transmission.

Tracking and Audit Trail Requirements

HIPAA regulations require healthcare organizations to maintain detailed audit trails for all PHI access and transmission activities. HIPAA compliant email encryption systems must provide logging capabilities that track message creation, transmission, receipt, and access events. These logs help during compliance audits and breach investigations.Automated tracking tools can identify unusual patterns in encrypted email usage that might indicate security threats or compliance violations. For example, systems can flag instances where users attempt to send large volumes of PHI or access encrypted messages from unusual locations.

Regular audit reviews help ensure that HIPAA compliant email encryption systems continue meeting regulatory requirements as organizations grow and technology changes. Healthcare entities should establish periodic assessment schedules to evaluate encryption effectiveness, user compliance, and system performance. These reviews help identify areas for improvement and ensure continued HIPAA compliance.

Zero Trust Email Security in Healthcare: A Requirement for Sending PHI?

April 15, 2026
Pete Wermter

As healthcare organizations embrace digital patient engagement and AI-assisted care delivery, one reality is becoming impossible to ignore: traditional perimeter-based security is no longer enough. Email, still the backbone of patient and operational communications, has become one of the most exploited attack surfaces.

As a result, Zero Trust email security in healthcare is moving from buzzword to necessity.

At LuxSci, we see this shift firsthand. Healthcare providers, payers, and suppliers are no longer asking if they should modernize their security posture, but how to do it without disrupting care delivery or patient engagement.

Our advice: Start with a Zero Trust-aligned dedicated infrastructure that puts you in total control of email security.

Let’s go deeper!

What Is Zero Trust Email Security in Healthcare?

At its core, Zero Trust email security in healthcare applies the principle of “never trust, always verify” to every email interaction involving protected health information (PHI).

This means:

Continuous authentication of users and systems
Device and environment validation before granting access
Dynamic, policy-based encryption for every message
No implicit trust, even within internal networks

Unlike legacy approaches that assume safety inside the network perimeter, Zero Trust treats every email, user, and endpoint as a potential risk.

Why Email Is a Critical Gap in Zero Trust Strategies

While many healthcare organizations have begun adopting Zero Trust frameworks for network access and identity, email often remains overlooked.

This is a major problem.

Email is where:

PHI is most frequently shared
Human error is most likely to occur
Phishing and impersonation attacks are most effective

Without a Zero Trust email security approach, organizations leave a critical gap in their defense strategy, one that attackers can actively exploit.

Healthcare Challenge: Personalized Communication and PHI Risk

Modern healthcare ecosystems are highly distributed:

Care teams span multiple locations
Third-party vendors access sensitive systems
Patients expect digital, personalized communication

This creates a complex web of PHI exchange—much of it through email.

At the same time, compliance requirements like HIPAA demand that PHI email security is addressed at all times.

The result is a growing tension between:

Security and compliance
Usability, engagement, and better outcomes

From Static Encryption to Intelligent, Adaptive Protection

Traditional email encryption methods often rely on:

Manual triggers
Static rules
User judgment

This introduces risk. A modern zero trust email security in healthcare model replaces this with:

Automated encryption policies based on content and context
Flexible encryption methods tailored to recipient capabilities – TLS, Portal Fallback, PGP, S/MIME
Seamless user experiences that human error – automated email encryption, including content

At LuxSci, our approach to secure healthcare communications is built around this philosophy. By automating encryption and providing each customer with a zero trust-aligned dedicated infrastructure, organizations can protect PHI without relying on end-user decisions or the actions of other vendors on the same cloud, significantly reducing risk while improving performance, including email deliverability.

Aligning Zero Trust with HIPAA and Emerging Frameworks

Zero Trust is not a replacement for compliance, it’s an enabler. A well-implemented Zero Trust approach helps organizations:

Meet HIPAA requirements for PHI protection
Reduce the likelihood of breaches
Strengthen audit readiness and risk management

More importantly, it positions healthcare organizations to align with emerging cybersecurity frameworks that increasingly emphasize identity, data-centric security, and continuous verification.

PHI Protection Starts with Email

Zero Trust is no longer a conceptual framework, it’s becoming the operational standard for healthcare IT, infrastructure, and data security teams.

But success depends on execution. Email remains the most widely used, and vulnerable, communication channels in healthcare. Without addressing it directly, Zero Trust strategies will fall short.

Here are 3 tips to stay on track:

Treat every email as a potential risk
Automate encryption at scale – secure every email
Enable personalized patient engagement with secure PHI in email

At LuxSci, we believe that HIPAA compliant email is the foundation for the future of secure healthcare communications, protecting PHI while enabling better patient engagement and better outcomes.

What Sets B2B Marketing In The Healthcare Industry Apart?

April 14, 2026
Kai Haughney

B2B marketing in the healthcare industry runs through a buying environment shaped by review, caution, and internal scrutiny. A vendor may catch interest quickly, yet a deal still has to survive procurement, legal input, operational questions, and, in some cases, clinical oversight. That changes the tone and structure of effective outreach. Buyers want clear information, credible framing, and content that holds up when shared across teams. Strong campaigns account for those conditions from the first touch, giving decision makers useful material at the right point in the conversation.

How B2B marketing in the healthcare industry differs from other sectors

Healthcare buying carries a heavier internal burden than many commercial categories. A decision can affect patient related workflows, staff time, data handling, vendor risk, and budget planning all at once. That wider impact shapes how people read. A finance lead may scan for commercial logic and resource use. An operations leader may think immediately about rollout pressure and process disruption. An IT contact may focus on access, integration, and control. Messaging has to stand up to each of those viewpoints. That is why strong healthcare outreach tends to move with more restraint, more clarity, and more attention to proof than campaigns built for faster sales environments.

Trust within B2B marketing in the healthcare industry

Trust grows through judgment on the page. Buyers notice inflated language very quickly, especially when it appears in sectors where risk and accountability are part of everyday work. A polished headline can attract attention, though the body copy still has to carry weight. Clear examples help. Plain explanations help. So does a tone that sounds measured enough for someone to forward internally without hesitation. A payer team may want to see how a service affects review speed or administrative flow. A provider group may care about intake, coordination, or staff workload. A supplier may look for signs that communication across partners will become smoother and easier to manage. Credibility builds when the writing shows a close read of the reader’s world.

Buying committees do not think alike

Most healthcare deals are shaped by several people with different pressures attached to their roles. Procurement may be looking for vendor reliability and a smoother approval process. Compliance may read for privacy exposure and documentation. Operations may focus on practical fit with current workflows. Finance may want a clearer commercial case before the conversation goes any further. Those concerns do not compete with one another so much as stack on top of one another, which is why broad messaging tends to flatten out. Better campaigns anticipate that mix. One sequence can speak to efficiency and team workload. Another can support legal and compliance review. A third can frame the economic rationale in language senior stakeholders will recognise immediately.

Content that helps a deal move

Healthcare content earns its place when it gives buyers something they can use, discuss, and circulate. A short article on referral bottlenecks can help an operations lead frame the problem more clearly. A concise guide to secure communication can help internal teams ask better questions during review. A comparison page on implementation models can help a buyer weigh practical tradeoffs before a call is even booked. Useful content creates momentum because it fits the way decisions are made. It enters the conversation early, gives people sharper language for internal discussion, and keeps the subject alive between meetings. That is where strong work starts to separate itself from content written simply to fill a calendar.

Measuring progress with better signals

Healthcare teams get a clearer picture when they look past surface numbers and pay attention to the signs attached to real interest. Repeat visits from the same account can matter more than a large burst of low value traffic. A reply from an operations contact may tell you more than a high open rate. Visits to implementation, privacy, or procurement pages can indicate that the discussion is moving into a more serious stage.

Patterns like these help commercial teams judge where attention is gathering and where timing is starting to matter. Good B2B marketing in the healthcare industry supports that process by creating sharper entry points for sales, stronger context for follow up, and a more informed path from early curiosity to active evaluation.

Why Does B2B Healthcare Email Marketing Matter To Healthcare Buyers?

April 14, 2026
Erik Kangas

B2B healthcare email marketing is the practice of using email to reach healthcare business audiences with timely, relevant communication that supports trust, evaluation, and purchase decisions. In healthcare, that means more than sending promotional copy. Buyers want proof that a vendor understands procurement realities, privacy expectations, clinical workflows, and the pace of internal review. When the message is well judged, email helps move a conversation forward without forcing it. It can introduce a problem, frame the business case, and give decision makers something useful to circulate inside the company while they weigh next steps.

What makes B2B healthcare email marketing work in real buying cycles?

The difference between ignored email and useful email is context. Healthcare deals rarely move on impulse, and very few readers want a sales pitch in their inbox after one click or one download. Good B2B healthcare email marketing takes its cues from where the buyer is in the process. A first touch might define a problem in plain terms. A later message may explain implementation questions, privacy considerations, or internal adoption issues. That sequencing matters because healthcare buyers read with caution. They are not just asking whether a product looks good. They are asking whether it can survive legal review, procurement review, and scrutiny from the teams who will live with it day after day.

How does compliance shape B2B healthcare email marketing?

Healthcare email lives under closer scrutiny than email in many other industries. If a campaign touches protected health information, HIPAA enters the conversation immediately, especially the Privacy Rule and Security Rule. Even when outreach is aimed at business contacts, teams still need a disciplined view of what data is stored, who can access it, and how consent, opt out, and message content are handled.

The CAN SPAM Act also matters because sender identity, subject line accuracy, and unsubscribe function are not small details. Strong B2B healthcare email marketing treats compliance as part of message design from the start. That leads to cleaner copy, better internal approval, and fewer edits after legal teams step in.

Which audiences respond best to B2B healthcare email marketing?

Healthcare buying groups are rarely made up of one decision maker. A payer executive may care about administrative efficiency and audit readiness. A provider operations leader may be focused on referral flow, patient intake, or staff time. A supplier may look at partner communication, order handling, or data movement between systems. B2B healthcare email marketing works better when each audience receives language that matches its concerns instead of one generic message sent to everyone. That does not require jargon. It requires precision in the everyday sense of the word. Readers need to feel that the sender understands the pressures attached to their role, not just the industry label attached to their company.

What kind of content earns trust instead of quick deletion?

Healthcare buyers respond well to emails that help them think clearly. A short note that explains why referral leakage happens will land better than a vague message about transformation. A concise example showing how a health plan cut review delays can do more than a page of inflated claims. This is where B2B healthcare email marketing becomes persuasive without sounding pushy. The best messages teach, but they also move. They give the reader one useful idea, one practical example, and one reason to keep the conversation alive. That balance matters because healthcare readers are trained to be skeptical, and skepticism is not a barrier when the content respects it.

How can teams judge whether the program is doing its job?

Open rate alone does not say much in a long healthcare sales cycle. A better read comes from the quality of replies, the number of relevant page visits after a send, the movement of target accounts through the pipeline, and the way contacts share content internally.

B2B healthcare email marketing earns its place when it helps sales teams enter conversations with better timing and better context. If email is drawing the right people back to security pages, implementation pages, or procurement material, that is a useful signal. The real win is steady progress with buyers who need time, evidence, and confidence before they move.

New HIPAA Security Rule Makes Email Encryption Mandatory—Act Now!

April 6, 2026
Pete Wermter

The 2026 Deadline Is Closer Than You Think

The upcoming HIPAA Security Rule overhaul is expected to finalize by mid-2026, and it’s shaping up to be one of the most significant updates in years. Healthcare organizations that fail to prepare, especially when it comes to email security, will face immediate compliance gaps the moment enforcement begins.

Mid-2026 may sound distant, but for healthcare IT and compliance leaders, it’s right around the corner. Regulatory change at this scale doesn’t happen overnight, it requires planning, vendor evaluation, implementation, and internal alignment.

This isn’t a gradual shift. It’s a hard requirement.

Encryption Is About to Become Mandatory

For years, HIPAA has treated encryption as “addressable,” giving organizations flexibility in how they protect sensitive data. That flexibility is disappearing.

Under the updated rule, encryption, particularly for email containing protected health information (PHI), is expected to become a required safeguard.

That means:

Encryption must be automatic and standard for email, not optional
Policies must be enforced consistently
Email security can’t depend on human behavior

If your current system relies on users to manually trigger encryption, it’s already out of step with where compliance is heading. If you’re not encrypting your emails at all, then now is the time to re-evaluate and rest your technology and policies.

Email Is the Weakest Link in Healthcare Security

Email remains the most widely used communication tool in healthcare—and the most common source of data exposure. Every day, sensitive information flows through inboxes, including patient records, lab results, billing details, plan renewals and appointment reminders. Yet many organizations still depend on:

Basic TLS encryption that only works under certain conditions
Manual processes that leave room for human error
Limited visibility into email activity and risk

It only takes one mistake, such as a missed encryption trigger or a misaddressed email, to create a reportable breach. Regulators are well aware of this. That’s why email is a primary focus of the upcoming HIPAA Security Rule changes.

The Cost of Waiting Is Higher Than You Think

Delaying action may feel easier in the short term, but it significantly increases risk. Once the new rule is finalized, organizations without compliant systems may face:

Immediate audit failures
Regulatory penalties
Expensive, rushed remediation efforts
Or worst of all, an email security breach

Beyond financial consequences, there’s also reputational harm. Patients expect their data to be protected. A single incident can immediately erode trust and damage your brand beyond repair.

Waiting until the end of 2026 also means that you’ll be competing with every other organization trying to fix the same problem at the same time, driving up costs and limiting vendor availability.

Most Email Solutions Won’t Meet the New Standard

Here’s the uncomfortable reality: many existing email platforms won’t be enough, especially those that are not HIPAA compliant. Common gaps include:

Encryption that isn’t automatic or policy-driven
Lack of Data Loss Prevention (DLP)
Insufficient audit logging for compliance reporting
Lack of Zero Trust security principles

On top of that, vendors without alignment to HITRUST certification and Zero-Trust architectures may struggle to demonstrate the level of assurance regulators will expect moving forward.

If your current solution wasn’t designed specifically for healthcare and HIPAA compliance, it’s likely not ready for what’s coming.

LuxSci Secure Email: Built for What’s Next

This is where a purpose-built solution makes all the difference. LuxSci HIPAA compliant email is designed specifically for healthcare organizations navigating the latest compliance requirements, not just today, but in the future regulatory landscape.

LuxSci delivers:

Automatic, policy-based encryption that removes user guesswork
Advanced DLP controls to prevent PHI exposure before it happens
Comprehensive audit logs to support audits and investigations
Zero Trust architecture that verifies every user and action

Additionally, LuxSci is HITRUST-certified, helping organizations demonstrate a mature and defensible security posture as regulations tighten. Email data protection isn’t about patching gaps, it’s about eliminating them.

Act Now or Pay Later

If there’s one takeaway, it’s this: the time to act is now. Start by asking a few direct questions:

Is our email encryption automatic and enforced?
Do we have full visibility into email activity and risk?
Is our vendor equipped for evolving HIPAA requirements?

If the answer to any of these is unclear, now’s the time to take action. Organizations that move early will have time to implement the right solution, train their teams, and validate compliance. Those that wait will be forced into reactive decisions under pressure.

Conclusion: The Time to Act is Now!

The HIPAA Security Rule overhaul is coming fast, and it’s raising expectations across the board. Encryption will no longer be addressable, but rather mandatory. As a result, email security can no longer be overlooked, and compliance will no longer tolerate gaps.

LuxSci HIPAA compliant email provides a clear, future-ready path for your organization, combining automated encryption, DLP, auditability, and Zero Trust security in one solution.

The real question isn’t whether change is coming. It’s whether your organization will be ready when it does.

FAQs

1. When will the updated HIPAA Security Rule take effect?
The changes to the HIPAA Security Rule are expected to be finalized and announced around mid-2026, with enforcement likely soon after, by the end of the year.

2. Will email encryption truly be mandatory?
Yes, current direction strongly indicates encryption will become a required safeguard, which could start later this year or in early 2027.

3. Is TLS encryption enough for compliance?
No. TLS alone does not provide sufficient, guaranteed protection for PHI.

4. Why is HITRUST important in this context?
HITRUST certification demonstrates a vendor’s strong alignment with healthcare security standards and will likely carry more weight with regulators.

5. How does LuxSci help organizations prepare?
HITRUST-certified LuxSci offers secure email with automated encryption, DLP, audit logs, and Zero Trust architecture, helping organizations meet evolving compliance demands.

How to Secure SMTP Email Delivery with TLS

August 29, 2023
Erik Kangas

Secure email sending is a priority for organizations that communicate sensitive data externally. One of the most common ways to send secure emails is with SMTP TLS. TLS stands for Transport Layer Security and is the successor of SSL (Secure Socket Layer). TLS is one of the standard ways that computers on the internet transmit information over an encrypted channel. In general, when one computer connects to another computer and uses TLS, the following happens:

Computer A connects to Computer B (no security)
Computer B says “Hello” (no security)
Computer A says, “Let’s talk securely over TLS” (no security)
Computers A and B agree on how to do this (secure)
The rest of the conversation is encrypted (secure)

In particular:

The conversation is encrypted
Computer A can verify the identity of Computer B (by examining its SSL certificate, which is required for this dialog)
The conversation cannot be eavesdropped upon (without Computer A knowing)
A third party cannot modify the conversation
Third parties cannot inject other information into the conversation.

TLS and SSL help make the internet a more secure place. One popular way to use TLS is to secure SMTP to protect the transmission of email messages between servers.

Secure SMTP Email Delivery with TLS

The mechanism and language by which one email server transmits email messages to another email server is called Simple Mail Transport Protocol, or SMTP. For a long time, email servers have had the option of using TLS to transparently encrypt the message transmission from one server to another.

When available, using TLS with SMTP ensures the message contents are secured during transmission between the servers. Unfortunately, not all servers support TLS! Many email providers, especially free or public ones, have historically not supported TLS. Thankfully, the trend is shifting. LuxSci found that most providers now support TLS- approximately 85% of domains tested as of July 2022.

Using TLS requires that the server administrators:

purchase SSL certificates
configure the email servers to use them (and keep these configurations updated)
allocate additional computational resources on the email servers involved.

For TLS transmission to be used, the destination email server must offer support for TLS, and the sending computer or server must be configured to use TLS connections when possible.

The sending computer or server could be configured for:

No TLS: never use it.
Opportunistic TLS: use it if available; if not, send it insecurely.
Forced TLS: use TLS or do not deliver the email at all.

How Secure is Email Delivery over SMTP TLS?

TLS protects the transmission of the email message contents. It does nothing to protect the security of the message before it is sent or after it arrives at its destination. For that, other encryption mechanisms may be used, such as PGP, S/MIME, or storage in a secure portal.

For sending sensitive information to customers, transmission security is the minimum standard for compliance with healthcare and financial regulations. TLS is appropriate to meet most compliance requirements and offers an excellent alternative to more robust and less user-friendly encryption methods (like PGP and S/MIME).

There are different versions of TLS- 1.0 and 1.1 use older ciphers and are not as secure, while TLS 1.2 and 1.3 use newer ciphers and are more secure. When an email is sent, the level of TLS used is as secure as can be negotiated between the sending and receiving servers. If they both support strong encryption (like AES 256), then that will be used. If not, a weaker grade of encryption may be used. The sending and receiving servers can choose the types of encryption they will support. If there is no overlap in what they support, then TLS will fail (this is rare).

What About Replies to Secure Messages?

Let’s say you send a message to someone that is securely delivered to their inbox over TLS. Then, that person replies to you. Will that reply be secure? This may be important if you are communicating sensitive information. The reply will use TLS only if:

The recipient’s servers support TLS for outbound email (there is no way to test this externally).
The mail servers (where the “From” or “Reply” email address is hosted) support TLS for inbound email.
Both servers support overlapping TLS ciphers and protocols and can agree on a mutually acceptable means of encryption.

Unless familiar with the providers in question, it cannot be assumed that replies will use TLS. So, what should you do? Ultimately, it depends on what compliance standards you must meet, the level of risk you are willing to accept, and the types of communications you send. There are two general approaches to this question:

Conservative. If replies must be secure in all cases, assuming TLS will be used is unreasonable. In this case, a more secure method should be used to encrypt the messages in transit and store them upon arrival. The recipient must log in to a secure portal to view the message and reply securely. Alternatively, PGP or S/MIME could be used for additional security.
Aggressive. In some compliance situations like HIPAA, healthcare providers must ensure that ePHI is sent securely to patients. However, patients are not beholden to HIPAA and can send their information insecurely to anyone they want. If the patient’s reply is insecure, that could be okay. For these reasons, and because using TLS for email security is so easy, many do not worry about the security of email replies. However, this should be a risk factor you consider in an internal security audit. Consider nuanced policies that allow you to send less sensitive messages with TLS while sending more sensitive messages with higher security.

What are the Weaknesses of SMTP TLS?

As discussed, SMTP TLS has been around for a long time and has recently seen a great deal of adoption. However, it has some deficiencies compared to other types of email security:

There is no mandatory support for TLS in the email system.
A receiver’s support of the SMTP TLS option can be trivially removed by an active man-in-the-middle because TLS certificates are not actively verified.
Encryption is not used if any aspect of the TLS negotiation is undecipherable/garbled. It is very easy for a man-in-the-middle to inject garbage into the TLS handshake (which is done in clear text) and have the connection downgraded to plain text (opportunistic TLS) or have the connection fail (forced TLS).
Even when SMTP TLS is offered and accepted, the certificate presented during the TLS handshake is usually not checked to see if it is for the expected domain and unexpired. Most MTAs offer self-signed certificates as a pro forma. Thus, in many cases, one has an encrypted channel to an unauthenticated MTA, which can only prevent passive eavesdropping.

The Latest Updates to Secure SMTP TLS

Some solutions help remedy these issues—for example, SMTP Strict Transport Security. SMTP STS enables recipient servers to publish information about their SMTP TLS support in their DNS. This prevents man-in-the-middle downgrades to plain text delivery, ensures more robust TLS protocols are used, and can enable certificate validation.

In addition, users can adopt TLS 1.3. NIST recommends that government agencies develop migration plans to support TLS 1.3 by January 1, 2024. LuxSci supports both SMTP MTA-STS and TLS 1.3.

How Secure SMTP TLS Email Works with LuxSci

Inbound TLS

LuxSci’s inbound email servers support TLS for encrypted inbound email delivery from any sending email provider that also supports that. For selected organizations, LuxSci also locks down its servers to only accept email from them if delivered over TLS.

Outbound Opportunistic TLS

LuxSci’s outbound email servers will always use TLS with any server that claims to support it and with whom we can talk TLS v1.0+ using a strong cipher. The message will not be sent securely if the TLS connection to such a server fails (due to misconfiguration or no security protocols in common). Outbound opportunistic TLS encryption is automatic for all LuxSci customers, even those without SecureLine.

Forced TLS

When Forced TLS is enabled, the message is either dropped or sent with an alternate form of encryption if the recipient’s server does not support TLS. This ensures that messages will never be sent insecurely. Forced TLS is also in place for all LuxSci customers sending to banks and organizations that have requested that we globally enforce TLS to their servers.

Support for strong encryption

LuxSci’s servers will use the strongest encryption supported by the recipient’s email server. LuxSci servers will never employ an encryption cipher that uses less than 128 bits (they will fail to deliver rather than deliver via an excessively weak encryption cipher), and they will never use SSL v2 or SSL v3.

Does LuxSci Have Any Other Special TLS Features?

When using LuxSci SecureLine for outbound email encryption:

SMTP MTA STS: LuxSci’s domains support SMTP MTA STS, and LuxSci’s SecureLine encryption system leverages STS information about recipient domains to improve connection security.
Try TLS: Account administrators can have secure messages “try TLS first” and deliver that way. If TLS is unavailable, the messages would fall back and use more secure options like PGP, S/MIME, or Escrow. Email security is easy, seamless, and automatic when communicating internally or with others who support TLS.
TLS Exclusive: This is a special LuxSci-exclusive TLS sending feature. TLS Exclusive is just like Forced TLS, except that messages that can’t connect over TLS are just dropped. This is ideal for low-importance emails that must still be compliant, like email marketing messages in healthcare. In such cases, the ease of use of TLS is more important than receiving the message.
TLS Only Forwarding: Account administrators can restrict any server-side email forwarding settings in their accounts from allowing forwarding to any email addresses that do not support TLS for email delivery.
Encryption Escalation: Often, TLS is suitable for most messages, but some messages need to be encrypted using something stronger. LuxSci allows users to escalate the encryption from TLS to Escrow with a click (in WebMail) or by entering particular text in the subject line (for messages sent from email programs like Outlook).
Domain Monitoring: When TLS delivery is enabled for SecureLine accounts, messages will never be insecurely sent to domains that purport to be TLS-enabled, i.e., TLS delivery is enforced and no longer “opportunistic.” The system monitors these domains and updates their TLS-compliance status daily.
Double Encryption: Messages sent using SecureLine and PGP or S/MIME will still use Opportunistic TLS whenever possible for message delivery. In these cases, messages are often “double encrypted.” First, they are encrypted with PGP or S/MIME and may be encrypted again during transport using TLS.
No Weak TLS: Unlike many organizations, LuxSci’s TLS support for SMTP and other servers only supports those protocol levels (e.g., TLS v1.0+) and ciphers recommended by NIST for government communications and which are required for HIPAA. So, all communications with LuxSci servers will be over a compliant implementation of TLS.

For customers who can use TLS to meet security or compliance requirements, it enables seamless security and “use of email as usual.” SecureLine with Forced TLS enables clients to take advantage of this level of security whenever possible while automatically falling back to other methods when TLS is unavailable.

Of course, using Forced TLS as the sole method of encryption is optional; if your compliance needs are more substantial, you can turn off TLS-Only delivery or restrict it so that it is used only with specific recipients.

If your email use cases are complicated, LuxSci’s flexibility enables the secure sending of emails to any recipient, regardless of their email service provider’s support for TLS. Contact the LuxSci sales team to learn more about our secure SMTP TLS email sending.

HIPAA-Compliant Email Marketing: FAQ

November 21, 2023
LuxSci

Email is an essential channel for most marketers. However, HIPAA regulations raise many questions for healthcare marketers who need to execute email marketing campaigns without violating patient privacy.

HIPAA is a complicated law that offers a lot of guidance but does not require the use of any specific technologies to protect patient privacy. The ambiguity causes a lot of confusion for marketers trying to integrate email into their marketing strategy. This article addresses some frequently asked questions about HIPAA-compliant email marketing and offers advice for securing patient data and futureproofing your marketing.

Do generic practice newsletters need to be protected?

Some marketers assume practice newsletters do not contain health information and, therefore, do not fall under HIPAA requirements. However, this assumption is often incorrect. Many are surprised to learn that protected health information can be implied from seemingly benign information.

In this way, many generic email newsletters often indirectly contain PHI because they are sent to lists of current patients. Email addresses are individually identifiable and combined with the email content; it may imply that they are patients of the practice. For example, say you send a “generic” newsletter to the patients of a dialysis clinic. An eavesdropper may be able to infer that the recipients receive dialysis. Therefore, the email reveals information about an individual’s health treatment, is PHI, and should be secured in compliance with HIPAA regulations.

In some cases, it can be complicated to determine what is PHI and what is not. Using a HIPAA-compliant marketing solution is best to avoid ambiguity and ensure security.

How Do I Find a HIPAA Compliant Email Marketing Vendor?

Unfortunately, using broadly popular email marketing platforms is not recommended. Many of these platforms were designed for e-commerce businesses and are 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 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 email messages and data in transit as it is 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.

What is an Email API?

API is an acronym that stands for “Application Programming Interface.” An email API gives applications (like CRMs, CDPs, or EHRs) the ability to send emails using data from the application. Email APIs also return campaign data to the platform or dashboards so you can assess the effectiveness of your marketing efforts. Trigger-based transactional or marketing emails are ideal for sending with an email API. In this situation, 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 appointment.

Email APIs enable the automation of common email workflows. However, they are not interchangeable with email marketing platforms. Email APIs do not include the contact management systems standard in most email marketing platforms because all that data lives within the application they connect to. In addition, email API tools typically do not include drag-and-drop editor tools or other design features that help your emails stand out.

Does HIPAA permit providers to send unencrypted emails with PHI to patients?

Encryption is an addressable standard under the HIPAA Security Rule, but that does not mean it is optional. The HIPAA Privacy 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.” 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.
Signed waivers do not insulate you from the consequences of a HIPAA breach.
And finally, using waivers to send unencrypted emails doesn’t eliminate your other HIPAA obligations like data retention and disposal. Using a HIPAA-compliant solution is more manageable and eliminates ambiguity.

Can patients exercise their right of access by receiving PHI via unencrypted email?

Yes, but they must be fully informed of the risks and sign waivers acknowledging them. The caveats in the previous answer apply. It’s always better to utilize an encryption tool to protect patient data.

Is Microsoft 365 or Exchange 365 encryption sufficient for marketing emails?

Microsoft 365 can be configured with Office Message Encryption (OME) to comply with HIPAA. However, the program is not well-suited to HIPAA email marketing. 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. If you are a marketer trying to increase engagement, the portal adds a barrier to access that many will not cross. Light-PHI marketing messages are best sent using TLS encryption. TLS-encrypted messages arrive in the recipient’s inbox just like a regular email and do not require a user to log in to read the message.

In addition, Microsoft 365 is not configured to send high volumes of email. If you plan to send large marketing campaigns, you could unintentionally disrupt regular business communications by sending all the messages through the same infrastructure. You should separate your business and marketing email sending to protect your IP reputation and achieve your desired sending throughput.

What are common email marketing use cases for healthcare?

Email marketing in healthcare is not restricted to boring practice newsletters. When you utilize tools that enable the use of PHI in your targeting and personalization efforts, the sky is the limit. With consumer preferences shifting toward digital communications, marketers willing to utilize the email channel and tactics like segmentation and personalization can see better results.

Email is an excellent way to communicate with patients. A sampling of ways that healthcare marketers can use email include:

engaging patients in their healthcare journey
educating patients about their healthcare conditions and treatments
improving attendance and scheduling
retaining patients
increasing preventative procedures
collecting data on the patient experience
improving patient satisfaction

Conclusion

HIPAA can be difficult to understand, but choosing the right tools and adequately vetting your vendors makes it easy to execute HIPAA-compliant email marketing campaigns. If you are interested in learning more about LuxSci’s easy-to-use, Secure Marketing platform, please contact our sales team.

Why Healthcare Insurers Should Send Explanation of Benefits Statements Via Email

July 30, 2025
Pete Wermter

Explanation of Benefits statements or EOBs are mission-critical communications for health insurers because they ensure transparency, help detect billing errors or fraud, and most importantly, keep patients informed about their benefits and related payments.

However, the most conventional method of sending out EoBs, traditional mail, has several drawbacks that can prevent important information about healthcare coverage from reaching the intended recipient. 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. This can also drive up inbound calls into your claims department or contact center.

Because Explanation of Benefits statements contain the protected health information (PHI) of policyholders, 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 electronic EoBs, which include enhanced security, better adherence to compliance regulations, and the opportunity to save millions of dollars per month.

Protecting Patient Privacy

The primary reason that insurance companies should shift to email EoBs as opposed to traditional mail is that it’s far more secure. Sending an EoB via email drastically decreases the risk of protected health information (PHI) getting into the wrong hands. When sent in paper form by mail, 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.

As detailed later in this post, email also allows for various controls and processes, which mitigate the risks of unsuccessful message delivery.

Most importantly, secure email provides data encryption, which safeguards the sensitive patient data within EoBs during transmission and when stored by rendering it unreadable to malicious actors who might intercept it. Physical mail, in contrast, offers no such protection, as someone who intercepts a paper EoB form can simply open it and freely read its contents.

Finally, secure email delivery platforms feature identity verification and access controls that enable healthcare insurers to restrict access to PHI to authorized personnel, limiting its exposure. They also provide auditing capabilities to track access to patient data, and quickly identify the source of security breaches.

HIPAA Compliance Benefits

Because sending an Explanation of Benefits statement via email is more secure, and better protects any patient data contained within them, this also reduces the risk of HIPAA compliance violations.

First and foremost, HIPAA regulations mandate that communications containing PHI, such as EoBs, must securely reach the intended recipient. By eliminating the risk of physical interception or non-delivery, and the compliance violations from a resulting security breach, insurers can better adhere to HIPAA regulations using email for sending EOBs. On a similar note, the security features built into a HIPAA compliant email platform, such as encryption, access controls, and audit logs, help insurers to 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. 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 can enable faster detection and containment of data breaches.

In stark contrast, physical mail is far more difficult to track – and even those limited capabilities are reserved for more expensive delivery options. Consequently, security breaches via mail could go unnoticed for days or even weeks. If you’re unaware of a data breach, or have not yet contained or mitigated it, you’re then unable to inform all affected parties, resulting in further HIPAA violations.

Increased Deliverability Rates

By greatly mitigating the security risks presented by physical mail, i.e., the various ways an EoB could fall into the wrong hands, sending an EoB by email increases your ability to get more EOBs into the hands of policyholders, more quickly. At the same time, policyholders can make faster decisions regarding their healthcare.

The ability to track secure email gives you greater control over EOB deliverability, as it allows organizations to determine the cause of delivery failure and can also make subsequent attempts. Additionally, the process of determining the reason for the message delivery failures can also reveal security issues; the same process, however, is very difficult to achieve with traditional mail.

Here’s how the typical protocol for resending a secured email goes beyond what you can do with managing traditional mail delivery:

Determine the cause of non-delivery: verify that the intended recipient information is correct and check for issues like a full email inbox or security misconfigurations.
Don’t automatically resend: to avoid exposing PHI to the wrong person, confirm the intended recipient’s email address through an alternative verified channel, e.g., phone call, secure SMS, etc.
Log the incident: document the delivery failure, steps taken to determine its cause, attempts, etc.
Reattempt message delivery: if the investigation deems it safe, attempt message redelivery with the corrected information.

In the event that subsequent delivery attempts fail, it’s best practice to contact the individual to arrange the most convenient and secure alternative to deliver their EoBs.

Cost Savings

Simply put, sending Explanation of Benefits statements via email instead of traditional mail saves health insurers money – potentially lots of it. Processing EOBs from start to finish can cost health insurers one to two dollars or more per EOB. That’s a lot. The biggest opportunity for cost reduction is tied to the money saved on printing and mailing paper EoB statements. Additionally, the cost of administering the delivery of EoB forms, ensuring their delivery, etc., is lowered when it’s done electronically. Not to mention, resending EoBs in the event of their non-delivery is much easier and cheaper via email.

In a broader sense, increasing the deliverability and the success rate of sending EoBs helps a larger number of policyholders better understand the details of their insurance coverage, i.e., how it works, which services and procedures it covers, etc. As a result of their policyholders being more informed, insurers won’t spend as much time explaining policy details and cost breakdowns to their members, allowing them to divert the otherwise required resources to other areas of the business.

Reduced Carbon Footprint

Finally, it’s difficult to highlight the benefits of sending EoBs to policyholders by email without recognizing the positive environmental impact, too. Email EoBs cut down on paper, for both the forms 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 or goals.
