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.

Rethinking HIPAA Compliant Email – Not Just a Checkbox

January 20, 2026
Pete Wermter

The compliance-only mentality is outdated.

Let’s be honest—when most healthcare organizations think about HIPAA compliant email, it’s usually in the context of avoiding fines or satisfying checklists. And while yes, compliance is critical, viewing it only through the lens of risk management is a missed opportunity.

In reality, HIPAA compliant email, when implemented properly, is one of the most powerful tools for patient and customer engagement. Why? Because it unlocks the ability to leverage protected health information (PHI) safely, enabling personalized, timely, and high-impact email communication that drives better engagement, satisfaction, and outcomes.

What Makes Email Truly HIPAA Compliant?

As a reminder, HIPAA compliant email requires that protected health information (PHI) is safeguarded both in transit and at rest. That means your email provider must:

Use encryption at all times

Be access-controlled

Include audit logs

Be stored and transmitted in a secure manner

Provide a Business Associate Agreement

Regular email services just don’t cut it. In fact, most consumer or marketing email platforms like Sendgrid or Constant Contact, while great at sending email, are not HIPAA compliant or have limitations when it comes to using PHI in your messages. Even when bolted-on encryption solutions are used, they often lack the flexibility, scalability, and automation needed for safe and effective healthcare email engagement.

LuxSci goes beyond the basics with policy-based encryption, secure TLS, PKI encryption and escrow/secure portal options. LuxSci’s SecureLine™ encryption technology dynamically selects the appropriate encryption method based on recipient capabilities and messaging context and can be configured to enforce secure delivery automatically according to organizational policies. LuxSci also provides the ability to enforce advanced multi-factor authentication. Every message is tracked with full audit trails—no guesswork, no loose ends.

The Real Opportunity – Secure, Personalized Email with PHI

Using PHI to Drive Personalized Messaging
Imagine sending a personalized reminder to a diabetic patient about an upcoming check-up. Or reaching out to new mothers with postnatal care resources tailored to their needs. Or sending automated email workflows to all your members to accelerate and increase new plan enrollments. Or email customer and prospects about a new product upgrade or new service offering. The list goes on. That’s the power of PHI-personalized email—when done securely.

Targeted Segmentation with Sensitive Data
With HIPAA compliant email solutions like LuxSci, you can segment your audience based on real health data with high levels of precision, such as chronic conditions, appointment history, insurance status, health risks, and more, without compromising patient trust or security.

Breaking the One-Size-Fits-All Approach in Healthcare Email
Generic email blasts are over. Modern patients expect personalization. With LuxSci, you can deliver highly targeted, highly secure emails with encrypted content, while staying HIPAA compliant.

Improving Health Plan Enrollments – Targeted email outreach during open enrollment, tailored by eligibility or plan type, and powered by automated workflows leads to higher enrollments and lower call center costs.
Driving Awareness and Sales of New Services or Products – Have a product upgrade offer, new wellness program or telehealth service? Send secure, PHI-informed HIPAA compliant email to the right audience for increased sales and faster adoption.
Optimize Explanation of Benefits Notices – Replace snail mail with email that’s fast, reliable and trackable, ensuring customers are informed and compliance is met.

The Healthcare Marketer’s Secret Weapon: Using PHI Responsibly

In a world moving away from third-party cookies, first-party data is more valuable than ever, and PHI is the most powerful form of it in healthcare. With secure HIPAA compliant email, PHI doesn’t have to be locked away. Marketers can safely use it to understand patient needs and send relevant, timely messages. PHI-driven segmentation lets you build hyper-targeted campaigns that speak to relevant conditions, unique needs and timely topics, increasing open rates, clicks throughs, and campaign conversions.

Meeting the Personalization Demands of Today’s Patients and Customers

HIPAA-compliant email is no longer just about checking a box. It’s about unlocking the full potential of your patient and customer data to drive better engagement, healthier outcomes, and measurable business results.

In closing, below are some final thoughts on how secure, HIPAA compliant email delivers long-term value for your organization and better connections with your patients and customers, including:

- Future-Proofing Healthcare Engagement – Patients expect Amazon-level personalization. HIPAA-compliant tools let you meet those expectations securely.

- Adapting to Data Privacy Regulations Beyond HIPAA – From GDPR to state-level privacy laws, secure communication is no longer optional, it’s foundational.

What Are the Objectives of Healthcare Marketing?

January 6, 2025
Erik Kangas

Successful healthcare marketing campaigns set measurable targets to engage patients and customers, build brand recognition, strengthen market position, and generate business growth, while meeting healthcare regulations and compliance requirements. Marketing teams develop strategies to meet these targets through patient outreach and service promotion, including email marketing and outreach campaigns. These strategies balance business development with patient engagement and compliance requirements, focusing on both short-term acquisition goals and long-term relationship building.

Healthcare Marketing Strategy Development

Marketing in healthcare requires detailed approaches that respect patient privacy and medical ethics. Marketing teams create plans that address both revenue targets and patient and customers needs, while navigating regulations that govern healthcare communications, privacy and data security. Their work includes market research, campaign development and messaging, and results tracking across multiple channels. These plans typically incorporate email, digital, and community outreach methods to connect with patients and healthcare partners. Teams analyze current patient segments, demographic data, local healthcare needs, and market opportunities to develop targeted campaigns that resonate with specific patient populations and groups. Marketing departments also work closely with medical and business line staff to ensure all messaging and content accurately represent healthcare services and products, while maintaining professional standards and brand consistency.

Audience Segmentation Techniques

Marketing teams can improve conversion rates by targeting their audiences by numerous subgroups. The teams divide potential patients and customers into multiple subgroups based on specific healthcare needs and conditions, service utilization patterns, demographics, and behavioral characteristics. These segments include patients with chronic condition management needs, those seeking preventive care, and individuals requiring specialized treatments. With the right campaign management tools, teams can create custom messaging for each segment addressing their concerns and interests. For example. departments conducting email healthcare marketing campaigns can use patient data to identify recurring treatment needs and develop targeted follow-up programs. They track response rates across different segments to refine their targeting approaches and message development. This segmentation allows for more efficient resource allocation and higher conversion rates across marketing channels.

Patient Outreach and Relationship Building

Marketing teams develop methods, such as email outreach campaigns, to reach new patients and maintain connections with current ones. The teams analyze patient data to understand healthcare usage patterns and create targeted outreach programs that address community needs. These programs include detailed health education materials, preventive care information, new products, and service updates delivered through carefully selected communication channels, typically over secure email and via patient portals. Marketing departments track patient engagement through these touchpoints, from initial contact, to product and service delivery, to ongoing relationships and active engagement. They measure program effectiveness through patient response rates, conversions, such as appointment scheduling patterns or new plan enrollments, and satisfaction surveys. This data helps teams refine their communication approaches and develop more effective patient engagement strategies. Healthcare marketing initiatives also focus on building trust through transparent communication about treatment options, costs, and expected outcomes, all of which needs to be transmitted securely win a way that meets HIPAA compliance requirements.

Building Healthcare Product and Service Awareness

Healthcare organizations should develop marketing campaigns to promote their range of medical services, products and/or specialties. Marketing teams typically research regional healthcare needs and service gaps to identify growth opportunities within specific medical areas. They create targeted promotion strategies for each service or product line, considering factors like local competition, patient demographics, and insurance coverage. These campaigns often include physician referral programs, community health education events, and specialized outreach to patient groups who might benefit from specific services. Again, it’s critical to secure these communications, especially when PHI is being used, to protect patient privacy and meet HIPAA compliance requirements. Teams should continuosly monitor performance through patient volume metrics, engagement rates and conversions, revenue tracking, and market penetration rates. This information guides decisions about resource allocation and helps identify which services need additional marketing support.

Market Position and Competitive Analysis

Healthcare providers should also conduct regular market analyses to understand their competitive position and identify opportunities for growth. Marketing teams study regional healthcare trends, track competitor offerings, and assess patient satisfaction with current services. They use this information to develop campaign strategies that highlight their unique capabilities and treatment options. Market research includes patient preference surveys, analysis of healthcare utilization patterns, and assessment of emerging medical technologies. Teams use these insights to adjust their healthcare marketing messages and service offerings to meet changing patient needs. They should also monitor their market share across different service lines and geographic areas to ensure marketing efforts maintain or improve their competitive position.

Performance Measurement and Optimization

Finally, marketing departments must establish detailed metrics to evaluate their programs and demonstrate return on investment to internal teams and management. This includes tracking patient acquisition costs, engagement, satisfaction scores, and revenue generation across all marketing initiatives. Teams should use analytics tools to measure campaign performance across different channels and adjust strategies based on results. Regular reporting helps organizations understand which marketing efforts deliver the best outcomes and where to focus future investments. This data-driven approach ensures healthcare marketing resources target the most effective channels and messages. Teams should also monitor long-term trends in patient and customer retention, and referral patterns to assess the lasting impact of their healthcare marketing efforts.

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.

What Is the Best HIPAA Compliant Email Software?

October 16, 2025

The best HIPAA compliant email software protects messages in transit and at rest, verifies identity with layered controls, records activity for audits, and connects cleanly with clinical systems. A service fits this description when encryption operates by default, authentication is strong but simple to use, logging is clear, and contracts map to HIPAA Privacy and Security Rule expectations so staff communicate without extra steps.

Why to seek out the Best HIPAA Compliant Email Software

Email carries scheduling details, follow ups, and billing questions from morning to close. The best HIPAA compliant email software keeps that flow steady by applying Transport Layer Security for server to server delivery and using message level encryption when a thread leaves trusted paths so only intended recipients can read the content. Identity needs careful handling through multi factor sign in, phishing resistant authenticators for sensitive roles, and session rules that make sense on shared workstations. Sender validation with SPF DKIM and DMARC reduces spoofing so patients and partner sites trust the name in the from line. When these elements run quietly in the background, teams move faster and errors linked to manual security steps fade.

Security Controls That Set Email Software Apart

HIPAA cites technical and administrative safeguards in 45 CFR 164.312 and 45 CFR 164.308. In practice this calls for access limits, audit trails, integrity checks, and transmission protection that does not rely on user memory. Default encryption policies remove guesswork during busy hours. Role based access narrows who can open attachments that carry imaging or lab data. Session timeouts that fit exam rooms and nursing stations reduce unattended access. The best HIPAA compliant email software turns these safeguards into daily behavior rather than optional features tucked inside menus, and that difference shows up in fewer service tickets and cleaner audits.

Contracts and Evidence

Any service that touches patient information requires a Business Associate Agreement with clear duties for data handling, incident reporting timelines, and return or deletion of information at contract end. Contract text needs to mirror access controls, audit controls, and transmission security in 45 CFR 164.312 along with administrative expectations in 45 CFR 164.308 so there is no gap between policy and reality. Independent examinations such as SOC 2 Type II or HITRUST provide outside confirmation that controls work as described, and written incident procedures with suitable insurance show preparation for hard days. Vendors that meet these barometers look much closer to the best HIPAA compliant email software because they can show how legal promises meet operational practice.

Integrations That Put Messages Into the Record

Care moves faster when messages land where work happens. Direct links to electronic health records place threads and attachments in the chart without copy and paste. Open APIs route patient replies and flags to the right queue so action follows quickly. Single sign on keeps access simple as clinicians move between rooms, and mobile access that preserves encryption and authentication lets providers respond away from a desk. When the inbox feels like part of the chart rather than a separate island, time spent juggling windows drops, and the best HIPAA compliant email software starts to feel invisible in the best possible way.

Administration and Support Built for Scale

Growth introduces rotating staff, new locations, and changing schedules. Administration needs clear role templates, delegated admin rights, and policy profiles that apply consistently across sites. Template management keeps patient facing messages consistent while allowing local details where needed. Support that guides DNS setup, archive import, and policy tuning shortens launch time and reduces rework. The best HIPAA compliant email software treats these operational pieces as first class concerns, which shows up later when a clinic adds a new line of service or merges with a partner and everything still works without a scramble.

Comparing the Best HIPAA Compliant Email Software

A focused pilot tells more than a long checklist. Test inside one service line and measure time to send a protected message, the rate at which patients open secure threads, and the steps needed to file conversations into the record. Track admin effort for onboarding, policy changes, and template updates. Review pricing beyond a seat line by including storage tiers, archive export, and support response times over a multi year term so totals stay predictable. Platforms that deliver encrypted transport, content protection when needed, dependable identity, complete logging, and clean connections to clinical systems will rise to the top, and that is where the best HIPAA compliant email software becomes easy to spot without naming vendors.

Budget Planning Without Surprises

Seat price rarely tells the whole story. Storage, export fees, and support commitments shape the total over time, as do retention rules that extend message life for legal or clinical reasons. Map these items to record policy and growth plans so expenses track reality. If a platform proves it can keep Protected Health Information private in motion and at rest, place messages into the chart without friction, and provide evidence that satisfies auditors, the decision gets simpler. In that situation the best HIPAA compliant email software supports daily communication while staying out of the way, which is exactly what busy clinics need.

Send Secure Emails: Alternatives to Web Portals

December 5, 2023

Digital technologies have entirely shifted how individuals want to interact with their healthcare providers. As consumers have become used to emailing or texting with their hairstylists, mechanics, and other providers to schedule appointments, they want to have the same level of interaction with their healthcare providers.

However, many healthcare organizations find it challenging to deliver the same experience because of their compliance requirements under HIPAA. They must balance usability and access with security and patient privacy. To send secure emails, they often resort to secure web portals.

Problems with Secure Web Portals

One of the most common ways that healthcare organizations communicate securely with patients is by using the secure web portal method of email encryption. In this scenario, messages are sent to a secure web server, and a notification is sent to the recipient, who then logs into the portal to retrieve the message.

While highly secure, this method is not popular with recipients because of the friction it creates.

To maintain a high level of security, users must log in to a separate account to retrieve the message. This extra step creates a barrier, especially for individuals who are not tech-savvy. In addition to creating a new account, they must remember a different username and password to access their secure messages. If the recipient doesn’t have this information readily available, they will likely delete the message and move on with their day. Many users will never bother logging in because of the inconvenience. This creates issues for organizations that want to use email for standard business communications and patient engagement efforts.

While this method may be appropriate for sending highly sensitive information like medical records, financial documents, and other valuable information, many emails that must meet compliance requirements only infer sensitive information and do not require such a high level of security. Flu shot reminder emails are not as sensitive or potentially devastating as sending the wrong medical file to someone. Healthcare organizations need to use secure email solutions that are flexible enough to send only the most sensitive emails to the portal and less sensitive emails using other methods.

How to Meet Compliance Requirements for Sending Secure Email

So, what other options do you have for sending secure emails? The answer will depend on what specific requirements you need to meet. Healthcare organizations that must abide by HIPAA regulations will find a lot of flexibility regarding the technologies they can use to protect ePHI in transit.

In addition to a secure web portal, three other types of encryption are suitable for email sending: TLS, PGP, and S/MIME. PGP and S/MIME are more secure than a web portal. They also require advanced technological skills and coordination with the end-user to implement, which makes them impractical for most business email sending.

That leaves us with TLS, which is suitable to meet most compliance standards (including HIPAA) and delivers an email experience much like that of a “regular” email.

Send Secure Emails with TLS Encryption

TLS encryption is an excellent option for secure email sending that provides a seamless experience for the recipient. Emails sent securely with TLS appear like regular, unencrypted emails in the recipient’s inbox.

TLS encrypts the message contents as they travel between mail servers to prevent interception and eavesdropping. Once the message reaches the inbox, it is unencrypted and can be read by anyone with access to the email account. For this reason, it is less secure than a portal but secure enough to meet compliance requirements like HIPAA.

If you’re wondering why this is, HIPAA only requires covered entities and business associates to protect PHI when it is stored on their systems or as it is transmitted elsewhere. After the message reaches the recipient, it is up to the recipient to decide what they want to do to secure the information. HIPAA does not apply to individuals. Each person is entitled to share and store their health information however they see fit.

Conclusion

Balancing security and usability is a significant challenge for healthcare organizations. If the message is too secure, it may be difficult for the recipient to open and engage with it. If it’s not secure enough, it is too easy for cybercriminals and other bad actors to intercept private information as it is sent across the internet.
