HIPAA Compliant Email, HIPAA Email Marketing
LuxSci
January 29, 2025

Choosing the right HIPAA-compliant email vendor is crucial for protecting patient data and ensuring compliance with healthcare regulations, including verifying HIPAA compliance and security features, evaluating ease of use and integration capabilities, assessing deliverability and performance, and understanding pricing and scalability. You should also evaluate a vendor’s customer support and company reputation.

The Health Insurance Portability and Accountability Act (HIPAA) details strict guidelines for securing sensitive patient data, including Protected Health Information (PHI). As a result, healthcare providers, payers, and suppliers must use a HIPAA-compliant email provider to abide by regulations designed to safeguard PHI.

With this in mind, this post evaluates two of today’s most popular HIPAA-compliant email providers on the market: LuxSci and Paubox. We’ll compare the two HIPAA-compliant offerings on several criteria, helping you to decide which email provider best fits the needs of your organization.

LuxSci vs. Paubox: Evaluation Criteria

We will evaluate LuxSci vs. Paubox on the following criteria:

Data security and Compliance: how well each email provider safeguards PHI as per HIPAA’s requirements
Performance and Scalability: the platform’s ability to conduct bulk email marketing campaigns, and scale them as a company’s engagement efforts grow.
Infrastructure: if it provides the necessary technical infrastructure, processes and controls to both protect sensitive patient data and support high-volume email marketing campaigns.
Marketing Capabilities: if the platform provides tools for optimizing and refining your communication strategies.
Ease of Use: how steep the learning curve is for each platform.
Other HIPAA-Compliant Products: if the email provider offers complementary features that will aid your patient engagement efforts.

Now that we’ve explained the parameters by which we’ll be comparing the HIPAA compliant email providers, let’s see how LuxSci and Paubox stack up against each other.

LuxSci vs. Paubox: How They Compare

Data Security and Compliance

Both LuxSci and Paubox perform admirably here, with both being fully HIPAA-compliant email providers, offering automated encryption that allows you to include PHI in email communications straight away. Both providers secure email data both in transit and at rest.

Additionally, both are HITRUST certified, which further demonstrates a strong commitment to data privacy and security.

When compared to Paubox, LuxSci has the edge here because it has more comprehensive encryption options. This includes highly flexible encryption: automatically setting the ideal level of security and encryption needs based on the email content, recipient and business process.

Performance and Scalability

While both email providers deliver proven solutions and enable healthcare companies to scale their email marketing campaigns accordingly, LuxSci is the better option for high-volume email marketing campaigns, including bulk sending of hundreds of thousands to millions of emails per month. This is due to the fact that LuxSci specializes in assisting large healthcare organizations with executing high volume email marketing campaigns, including companies like Athenahealth, 1800 Contacts, Eurofins, and Rotech medical equipment. Consequently, LuxSci offers enterprise-grade scalability and has developed robust solutions capable of the high throughput required for enterprise-level patient and customer engagement efforts.

Infrastructure

Additionally, when it comes to other aspects related to infrastructure, LuxSci demonstrates an advantage. Firstly, they offer a dedicated, single tenant infrastructure, as well as secure email hosting, while Paubox does not. Additionally, though Paubox can provide additional options, such as high availability and disaster recovery, their capabilities may not as comprehensive as LuxSci.

Marketing capabilities

Both email delivery platforms possess useful marketing tools, enabling more effective HIPAA-compliant email marketing. This includes automation for streamlining email marketing campaigns and, customization options, so your messages are both more compelling and align with your company’s branding.

LuxSci offers comprehensive reporting capabilities, including real-time monitoring, detailed performance metrics (e.g., deliverability, open and click-through rates, bounced emails, spam complaints, and recipient domain reporting), as well as granular segmentation options.

Ease of use

Paubox has the edge here, being the easier of the two HIPAA-compliant email providers to deploy and for staff to get to ramp up on. Suited for more complex and sophisticated environments, LuxSci offsets this with exemplary customer support honed from decades of facilitating organizations’ HIPAA-compliant email marketing campaigns – especially for this on a large scale.

Other HIPAA-compliant Products

Lastly, when it comes to complementary features, both LuxSci and Paubox offer secure texting functionality, allowing healthcare companies to cater to their patients and customers who prefer to communicate via SMS. And while both email providers feature secure forms for HIPAA-compliant data collection, LuxSci’s forms are capable of handling complex workflows, including multi-step data collection, and providing better customization options.

Additionally, both provide capabilities for secure file sharing. LuxSci’s secure file sharing encrypts files at rest and in transit, allowing for granular access controls and helping ensure that only those within your company who must handle PHI have the appropriate access permissions. This is yet another safeguard against the exposure of PHI, whether accidentally, through identity theft (e.g., session-hijacking by a cybercriminal), or even corporate espionage.

What you’ll learn:

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.

Reach out today. We can look at your existing set up, help you identify the gaps, and show you how LuxSci can help!

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.

How To Send HIPAA Compliant Emails

January 6, 2025
Erik Kangas

Knowing how to send HIPAA Compliant Emails is a critical requirement for healthcare providers, payers and suppliers dealing with protected health information (PHI). With fines reaching into the millions, non-compliance isn’t something you want to risk when engaging with our customers and prospects. Unfortunately, many organizations fall into the trap of believing they’re sending HIPAA compliant email because they’ve applied what we call “self-certification” strategies—without fully understanding what’s required to be compliant.

Are you 100% sure that you’re sending HIPAA compliant emails and understand HIPAA email rules?

In this blog post, we’ll delve into the risks of being non-compliant, explain why self-certification strategies often lead to problems, and provide a HIPAA-compliant email checklist to help ensure your organization avoids the pitfalls self-compliance.

The Importance of Sending HIPAA Compliant Emails

HIPAA (Health Insurance Portability and Accountability Act) was established to ensure the protection and privacy of patients’ PHI. This law mandates that any entity handling PHI must implement strict safeguards to prevent unauthorized access, breaches, and exposure of sensitive patient data.

In today’s digital world, where healthcare communications often take place over email and other digital platforms, maintaining HIPAA compliance becomes even more complex. It’s not enough to merely think you’re compliant; you must be able to prove it beyond a doubt.

What Is PHI and Why Does It Need to Be Protected?

As a quick reminder, PHI refers to any data that can be used to identify an individual and that relates to their past, present, or future health condition. This can include anything from personal identification info to medical records and billing information to email exchanges that reference patient care.

Examples of PHI include:

Names
Addresses
Birth dates
Social Security numbers
Medical history and diagnoses
Treatment plans & prescriptions
Medical device usage and services
Appointment information
Billing, payments and insurance information

The Risks of Not Being 100% Sure About HIPAA Compliance

In addition to losing sleep at night, the consequences of sending non-compliant emails can be significant. Non-compliance can result in hefty penalties, ranging from $100 to $50,000 per violation, depending on the severity and intent. In some cases, these fines can even surpass $1.5 million annually.

But it’s not just the fines—PHI exposure opens the door to a variety of serious risks, including the reputational damage that can stem from breaches of patient data that can impact peoples’ lives and the future of your business. Patients place immense trust in healthcare providers and organizations to safeguard their sensitive information, which stretches beyond HIPAA-compliance to overall data security and privacy. The loss of patient trust is difficult—if not impossible—to regain once compromised.

The Problem with DIY HIPAA Compliance

Simply put, self-certifying HIPAA compliance is a recipe for disaster. Many companies and healthcare organizations falsely believe that if they conduct an internal review or have implemented basic security measures, they’re fully compliant. But without the right expertise and the right HIPAA compliant infrastructure in place, especially encryption, it’s easy to overlook details.

Even if you have encryption in place or think your emails are safe, these minimal steps can create a false sense of security. True HIPAA compliance requires continuous monitoring, updating of policies, and regular training to address potential risks.

A Checklist for Sending HIPAA Compliant Email

Sending HIPAA compliant email means ensuring you’ve implemented the following safeguards:

1. Encryption Standards for HIPAA Compliance

All emails containing PHI must be encrypted both at rest and in transit—end-to-end. Ensure your email service provider offers high-grade encryption protocols, like TLS (Transport Layer Security), for sending and receiving messages, and flexible options, including dedicated cloud infrastuctures for the highest levels of data protection.

2. Secure Access and Authentication

Set up multi-factor authentication (MFA) and role-based access controls to limit who can access emails containing PHI.

3. Business Associate Agreements (BAA)

If you’re using a third-party email provider, you must have a signed BAA. This agreement ensures that the provider will uphold HIPAA’s security standards.

4. Data Backup and Recovery

Make sure your email system has a secure backup and recovery solution. Data breaches can happen, but having a recovery plan will minimize damage and maintain compliance.

5. Employee Training and Awareness

Ensure your employees are regularly trained on HIPAA guidelines. Human error is a leading causes of HIPAA violations, so proper education is key.

6. Regularly Audit Your HIPAA Compliance Strategy & Practices

HIPAA regulations evolve as technology advances. Conducting regular compliance audits ensures your security protocols are up to date with the latest best practices.

7. Avoiding Overconfidence in Your Own Processes

No matter how confident you are in your HIPAA strategy, bringing in an external auditor can provide an unbiased view of your compliance status and help identify overlooked vulnerabilities.

Don’t Let HIPAA Self-Certification Fool You!

HIPAA compliance is not something you can afford to be unsure about. The risks—both financially and reputationally—are too great. While it may be tempting to “self-certify” or assume your current measures are sufficient, doing so can leave your organization—and your patients and customers—vulnerable. Instead, ensure that you follow a comprehensive strategy that includes best-in-class email encryption, secure access, regular audits, employee training, and support from external experts.

Don’t take shortcuts when it comes to protecting sensitive health information and ensuring HIPAA compliance—get it right from the start.

HIPAA Compliant Email Use Cases for Health Plan Administrators and Insurance Providers

October 6, 2025
Pete Wermter

Email is still one of the most pervasive and trusted digital communication channels in use today — and it’s not going anywhere. For health insurance providers and health plan system administrators, email presents a major opportunity: the ability to communicate reliably, more personally, and more effectively with members and customers.

Despite this, some health insurers and plan providers are wary of utilizing email to its full potential for fear of running afoul of HIPAA regulations. Or worse, they think they’re HIPAA compliant when they may not be, or they don’t think they need to be compliant when it comes to certain communications.

When email is encrypted properly, it becomes a direct, compliant channel for everything from new plan enrollments and policy changes to Explanation of Benefits (EOBs) and reimbursements. With the right encryption methods and best practices in place, you can deliver the kind of personalized, efficient experiences that today’s members and customers expect, while meeting the highest standards for privacy and security.

With this in mind, let’s explore the most impactful HIPAA compliant email use cases for health plan administrators and health insurance providers – and how enabling secure, fully encrypted email with LuxSci can improve member engagement, drive more efficient processes, speed payment, and deliver better results and outcomes.

Email: A Highly Trusted Healthcare Communication Channel

Everyone uses email. It’s a daily habit for billions of people – including your members and customers. Email is also a top channel for baby boomers, and it will continue to be for years to come.

Simply put, people are familiar and comfortable with how email works, they trust it, and email doesn’t require the installation and use of another app or logging into a separate portal. For health plans and insurers, this means you can meet members and customers directly where they already are, through a highly used method of communication.

A Private and Preferred Option for Key Healthcare Conversations

When designed with security in mind, email is perfectly suited for delivering sensitive healthcare information, i.e., protected health information (PHI) and conversations about an individual’s health condition, related treatment, and insurance coverage. Just as importantly, it’s can be less invasive than SMS, and more effective – not to mention cheaper – than printed mail, making it an ideal choice for critical, high-touch communications, such as member benefits, policy updates, and billing.

HIPAA Compliance: Securing Better Digital Engagement

HIPAA compliance often gets framed as a limitation; in reality, however, it provides the framework for secure, scalable communications in healthcare.

With the right HIPAA compliant email solution, health plan administrators and health insurers can:

Deliver personalized content directly to members and customers – securely
Automate secure communications and related workflows
Avoid the additional friction of portals – and capture non-portal users
Ensure privacy and legal protection for sensitive data

Rather than avoiding email for sensitive communications, more and more organizations are now embracing secure email to improve engagement, click-throughs and conversions. This translates to more timely plan enrollments, more policy renewals and faster payments.

Compliance Enables Engagement, Not the Other Way Around

When you build compliance into your communications strategy, you unlock more ways to engage with members effectively. Confident in the safeguards you have in place to protect sensitive member and customer data, you can personalize your email communications, segmenting members according to their healthcare needs, their status within your organization, or their individual situation (recently joined, long-time member, disengaged, etc).

Consequently, HIPAA compliance doesn’t have to slow you down, as it’s persistently perceived to, it actually enables you to harness the possibilities of personalization to drive better engagement and better results.

HIPAA Compliant Email Use Cases for Health Plan Administrators and Insurers

Let’s turn our attention to five highly applicable use cases for HIPAA compliant email for health plans and insuers, and how they can benefit your company, as well as your members or customers.

Use Case #1: Sending Explanation of Benefits (EOBs)

Why It Matters: Reliable delivery, faster payments

In most cases, EOBs are still sent via physical mail, which is slow, costly, often misunderstood, and may never reach the intended recipient for myriad reasons. Conversely, with HIPAA compliant email, you can deliver digital EOBs directly to members in a format they can understand and trust is secure – at a much lower cost.

Benefits

Increased deliverability
Reduce printing and mailing costs
Reduced carbon footprint
The ability to track message activity, i.e., if delivered, opened, etc.

Use Case #2: New Plan Enrollments

Why It Matters: Secure enrollments, faster and on time

Enrollment is a crucial moment on the member journey. With secure email, you can onboard new members more quickly by reaching them directly via their inbox, providing them with their enrollment instructions, required logins, delivering their plan details, and supplying coverage summaries. All of which can be achieved without them having to wait for the mail or chase portal logins.

Benefits

Real-time delivery of enrollment and onboarding materials
Immediate coverage confirmation
Easier to troubleshoot potential issues
Enhanced support with secure reply options

Use Case #3: Policy Change and Renewal Notifications

Why It Matters: Transparency and speed build trust

Policy updates, such as changes to deductibles, coverage, or provider networks, must be communicated clearly and as soon as possible. HIPAA compliant email makes it simple to notify members and deliver legally required communications reliably and securely.

Benefits

Keep members better informed and more empowered to make healthcare decisions
Meet regulatory deadlines
Align with compliance requirements
Reduce call center volume from confused policyholders

Use Case #4: Payments, Reimbursements and Financial Communications

Why It Matters: Payment and coverage clarity drives satisfaction, business continuity

From payment confirmations to out-of-pocket estimates, secure email gives members clear, timely financial updates, allowing them to plan accordingly. This makes them feel their healthcare providers are being open with them and transparent in communications for payments.

In contrast, confusion about benefits, coverage, and costs diminishes trust, which strains communication and makes effective engagement difficult. Financial clarity also accelerates your organization’s internal processes, enhancing efficiency and your ability to provide the best possible service to members.

Benefits

Increased member trust and satisfaction
Speed up reimbursement cycles
Reduce payment confusion
Enable secure document submission (e.g., receipts, claims)

Use Case #5: Education and Preventive Health Campaigns

Why It Matters: Proactive education supports better health outcomes

Use HIPAA compliant email to send targeted content, including preventive screening reminders, wellness resources, and seasonal health tips, while effectively securing PHI. Members benefit by taking a more active role in their healthcare journeys and committing to better health, which reduces healthcare costs and improves outcomes.

Benefits

Educated members are more involved in their healthcare journey
Personalized health education based on member history
Secure mass communication that meets HIPAA standards

What Is HIPAA For Explanation Of Benefits Statements?

June 6, 2025
Erik Kangas

HIPAA for explanation of benefits statements includes privacy protections, disclosure limitations, and patient access rights that healthcare providers, payers, and suppliers need to understand when handling these documents. These requirements govern how explanation of benefits forms can be shared, stored, and transmitted while protecting patient information. Healthcare organizations processing explanation of benefits communications encounter specific HIPAA obligations that affect billing workflows, patient communications, and third-party interactions.

Privacy Protections in Explanation of Benefits Communications

HIPAA for explanation of benefits statements requires health plans to protect patient information contained within these documents. Explanation of benefits forms contain protected health information including patient names, dates of service, provider details, and treatment codes that qualify for privacy protections under HIPAA regulations. Health insurers processing explanation of benefits must implement safeguards to prevent unauthorized access, use, or disclosure of this information during document creation, transmission, and storage processes. The privacy protections extend to electronic and paper-based explanation of benefits communications. Health plans sending explanation of benefits via email need encryption or secure patient portals to protect information during transmission. When mailing paper explanation of benefits, insurers must use appropriate addressing and packaging to prevent accidental disclosure to unintended recipients. Correct implementation of these privacy measures prevents unauthorized access and maintains patient confidentiality.

Patient Access Rights for Explanation of Benefits Documents

Patients have specific rights under HIPAA regarding their explanation of benefits statements, including the right to receive copies, request corrections, and control how these documents are shared. Health plans must provide explanation of benefits to patients within reasonable timeframes and allow patients to designate how they prefer to receive these communications. Patients can request explanation of benefits in specific formats or ask that copies be sent to alternative addresses when medically necessary or for safety reasons. The right to request amendments applies to explanation of benefits when patients identify errors in treatment descriptions, billing codes, or other information contained within these documents. Health plans must have procedures for handling amendment requests and responding to patients within required timeframes. When approved, health plans must accommodate these requests according to HIPAA timelines and notification procedures.

Disclosure Rules for Explanation of Benefits Information

Health plans must follow certain disclosure rules when sharing explanation of benefits information with healthcare providers, patients, and third parties. HIPAA allows disclosure of explanation of benefits information for treatment, payment, and healthcare operations without patient authorization, but requires minimum necessary standards to limit information sharing to what is needed for the specific purpose. Healthcare providers can receive explanation of benefits details related to their patients’ claims processing and payment status as part of routine payment operations. Disclosure to family members or personal representatives requires either patient authorization or demonstration that the person has legal authority to act on the patient’s behalf. Health plans cannot share explanation of benefits information with employers, even when the employer sponsors the health plan, without specific patient authorization or as permitted under limited circumstances outlined in HIPAA regulations. Patient privacy remains protected while enabling health plans to conduct necessary payment and administrative activities.

Electronic Transmission Requirements for Explanation of Benefits

Electronic transmission of explanation of benefits requires compliance with HIPAA security standards to protect patient information during digital communication processes. Health plans using email, patient portals, or other electronic methods to deliver explanation of benefits must implement appropriate safeguards including encryption, access controls, and transmission security measures. These requirements apply whether explanation of benefits are sent as attachments, embedded in secure messages, or accessed through online platforms. The security requirements also cover explanation of benefits data stored in electronic systems, requiring health plans to implement administrative, physical, and technical safeguards to protect this information from unauthorized access or disclosure. Audit controls help track who accesses explanation of benefits information and when, providing accountability and helping identify potential security incidents. Organizations benefit from conducting periodic reviews to address emerging security challenges and technology updates.

Business Associate Obligations for Explanation of Benefits Processing

Third-party vendors processing explanation of benefits on behalf of health plans operate as business associates under HIPAA and must comply with specific obligations when handling this protected health information. Business associate agreements must outline how vendors will protect explanation of benefits data, limit its use to authorized purposes, and report any security incidents or unauthorized disclosures. These agreements help ensure that outsourced explanation of benefits processing maintains the same privacy and security protections required of health plans. Business associates processing explanation of benefits must implement appropriate safeguards for the information they handle and ensure that any subcontractors also comply with HIPAA requirements. The obligations include limiting access to explanation of benefits information to authorized personnel, providing security training, and maintaining audit logs of information access and use. Proper contract management and oversight ensure that all parties handling explanation of benefits information maintain appropriate privacy standards.

Compliance Monitoring for Explanation of Benefits Practices

Healthcare organizations need to consistently assess their explanation of benefits practices to ensure continued HIPAA compliance. Conducting audits also helps to identify potential gaps in privacy protections, disclosure practices, or security measures that could lead to violations. Training programs help staff understand their responsibilities when handling explanation of benefits information and keep them updated on regulatory changes that affect these communications. Incident response procedures specifically address explanation of benefits-related security breaches or privacy violations, including notification requirements and remediation steps. Documentation of explanation of benefits practices, policies, and training helps demonstrate compliance efforts during regulatory reviews or investigations. Consistent monitoring and documentation create a foundation for sustainable HIPAA compliance across all explanation of benefits operations..
