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:

The HIPAA Security Rule Missed Its May Deadline — Here’s What We Know

June 9, 2026
Pete Wermter

The proposed HIPAA Security Rule update has become one of the most closely watched healthcare compliance developments in recent years. Designed to strengthen cybersecurity protections for electronic protected health information (ePHI), the proposal could significantly reshape how healthcare organizations approach risk management, ePHI encryption, and mandatory email encryption requirements.

A final rule was expected as early as May 2026. However, that deadline has now passed without publication from the U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR).

So, what happens next—and what should healthcare IT directors, CISOs, and compliance officers do now?

Where Things Stand Today

The HIPAA Security Rule Notice of Proposed Rulemaking (NPRM) was published on January 6, 2025, with the goal of strengthening cybersecurity protections for ePHI in response to escalating ransomware attacks, healthcare breaches, and growing concerns about cyber resilience across the healthcare sector.

The proposal generated thousands of public comments from healthcare providers, payers, business associates, technology vendors, and industry groups. OCR has spent much of the past year reviewing this feedback and evaluating the operational and financial impact of the proposed changes.

Although the Spring Unified Regulatory Agenda identified May 2026 as a target date for a final rule, that milestone came and went without publication. As of June 2026, the proposed HIPAA Security Rule update remains under review.

While some organizations may be tempted to take a wait-and-see approach, the missed deadline should not be interpreted as a signal that the initiative has stalled. If anything, the proposal offers valuable insight into the future direction of healthcare cybersecurity regulation.

The Growing Focus on Mandatory Email Encryption

One of the most discussed aspects of the proposed HIPAA Security Rule update is encryption.

Under the current HIPAA Security Rule, encryption is generally classified as an “addressable” implementation specification. Organizations can choose alternative safeguards if they document and justify their decisions through a risk analysis process.

The proposed changes would significantly reduce that flexibility. Instead, many security safeguards, including encryption controls, would become more prescriptive and difficult to avoid.

While the final language has not yet been released, healthcare organizations should pay close attention to the proposal’s clear message: protecting ePHI through encryption is increasingly viewed as a baseline cybersecurity requirement.

This is particularly important for email communications.

Email remains one of the most widely used communication channels in healthcare, supporting everything from patient engagement and care coordination to billing, scheduling, and marketing communications. As regulators continue to focus on reducing data breach risks, mandatory email encryption is emerging as a likely area of increased scrutiny.

What Healthcare Organizations Should Do Now

The current delay creates an opportunity, not a reason to postpone action.

Healthcare organizations can begin preparing for likely requirements today by evaluating the security controls highlighted throughout the proposed rule.

Key areas to review include:

Encryption of ePHI across systems and communications channels
Comprehensive asset inventories and ePHI data mapping
Enhanced risk analysis and risk management processes
Multifactor authentication (MFA)
Vulnerability scanning and penetration testing
Incident response planning and testing
Backup and recovery procedures
Email security and secure email encryption practices

Organizations that proactively strengthen these areas now will be better prepared regardless of the final rule’s implementation timeline.

Why Secure Email Encryption Should Be a Priority

For many healthcare organizations, email remains one of the largest compliance and security risks.

Human error, misdirected messages, phishing attacks, and inconsistent encryption practices continue to contribute to breaches involving protected health information. As a result, secure email encryption is increasingly becoming a foundational component of healthcare cybersecurity strategies.

Organizations that rely on manual encryption processes or employee judgment alone may find it difficult to meet evolving regulatory expectations.

Instead, healthcare organizations should look for solutions that automate encryption decisions, reduce user error, and provide flexibility based on the sensitivity of the communication.

At LuxSci, we have long believed that security and usability must work together. We are 100% focused on secure healthcare communications, helping healthcare providers, payers, and suppliers protect sensitive data while improving patient and customer engagement. Our proven secure email solutions, used by leading companies including Athenahealth, 1-800 Contacts, and Hinge Health, help organizations protect ePHI with automated encryption capabilities that support both compliance and operational efficiency. Our unique SecureLine encryption technology enables organizations to apply the appropriate level of protection while maintaining a seamless experience for patients, customers, and staff.

For organizations already using Microsoft 365 or Google Workspace, LuxSci Secure Email Gateway can add HIPAA-compliant email security and encryption without requiring users to change their existing workflows. This approach helps reduce risk, while preserving productivity and user adoption.

The Bottom Line

The HIPAA Security Rule final rule may have missed its anticipated May deadline, but the cybersecurity challenges driving the proposal remain very real.

The OCR is still expected to make the rule change, which could require mandatory encryption of ePHI by early 2027.

The time to prepare is now!

Healthcare organizations should view the proposed HIPAA Security Rule update as an advance warning of where regulatory expectations are heading. Stronger cybersecurity controls, enhanced risk management, ePHI encryption, and mandatory email encryption requirements are all likely to remain central themes in future compliance efforts.

The organizations that begin preparing now will not only be better positioned for future regulatory changes, but will also strengthen their ability to protect patient data, reduce risk, and build trust in an increasingly challenging threat landscape.

At LuxSci, we’re proud to support the healthcare industry’s ongoing digital transformation through secure healthcare communications.

Is OCR Already Enforcing Email Encryption Under the New HIPAA Security Rule?

May 12, 2026
Pete Wermter

Healthcare organizations waiting for the final HIPAA Security Rule updates before improving email encryption and security may already be behind.

While the proposed changes to the HIPAA Security Rule are expected to be finalized in May, the direction from the U.S. Department of Health and Human Services Office for Civil Rights (OCR) is becoming increasingly clear. Across investigations, settlements, and enforcement actions, OCR continues emphasizing stronger technical safeguards, encryption, documented security programs, multi-factor authentication (MFA), risk analysis, and proactive cybersecurity operations.

For healthcare organizations, one area stands directly in the middle of all of these priorities: email.

Email remains a primary communication channel in healthcare — and one of the industry’s largest security vulnerabilities. From unauthorized PHI exposure to phishing attacks and ransomware delivery to account compromise, email continues to be at the center of healthcare cybersecurity incidents.

So, are the proposed HIPAA Security Rule changes hypothetical future guidance or a preview of OCR’s future enforcement expectations?

For healthcare email security, the implications are significant.

Email = Healthcare Cybersecurity Risk

Healthcare organizations rely on email for critical communications and healthcare workflows, including:

Patient communications
Care coordination
Claims and billing notifications
Marketing and engagement
Internal collaboration
Third-party vendor communications
Delivery of sensitive PHI

At the same time, attackers continue targeting email systems because they remain one of the easiest entry points into healthcare environments.

Insecure email workflows create unnecessary exposure of protected health information. Phishing campaigns are becoming more sophisticated. Credential theft attacks are bypassing traditional MFA methods. And business email compromise (BEC) attacks continue rising.

Recent OCR enforcement actions increasingly reflect these realities.

Organizations are being evaluated not simply on whether a breach occurred, but whether they implemented reasonable safeguards beforehand, including encryption, authentication controls, monitoring, access management, and documented risk mitigation processes.

For email systems specifically, that means healthcare organizations should expect increased scrutiny around:

Email encryption enforcement
MFA deployment
Audit logging and retention
Conditional access policies
Vendor security controls
Secure email delivery best practices
Segmentation and infrastructure isolation
Ongoing patch and vulnerability management

In many ways, email infrastructure is becoming a visible test of an organization’s overall cybersecurity posture.

Email Encryption Is Moving From Addressable to Required

Historically, healthcare organizations often interpreted HIPAA email encryption requirements with flexibility because encryption was technically categorized as an “addressable” safeguard under the Security Rule. But, OCR enforcement and broader cybersecurity realities are changing that interpretation rapidly.

Today, failing to encrypt sensitive healthcare communications increasingly creates both security and regulatory risk. The proposed Security Rule updates place even greater emphasis on encryption and technical safeguards. At the same time, OCR investigations continue examining whether organizations properly protected PHI in transit and at rest.

For healthcare email specifically, this creates several growing expectations:

Email encryption should be automated wherever possible
Human error should not determine whether PHI is protected
Organizations should maintain documented encryption policies
Secure delivery methods should adapt dynamically to recipient capabilities
Audit trails should demonstrate how messages were secured

At LuxSci, we have long believed that encryption should operate as a strategic layer of healthcare communications infrastructure, not as a manual user decision.

Our SecureLine email encryption technology automatically applies appropriate encryption methods based on organizational policies and delivery requirements, helping reduce the risks associated with human error while maintaining usability, deliverability and compliance. As enforcement expectations rise, this type of automated security enforcement is becoming increasingly important.

Traditional MFA May No Longer Be Enough

Another major shift emerging from both OCR enforcement trends and the proposed rule updates is the growing importance of stronger authentication models.

Healthcare organizations have historically viewed MFA deployment as sufficient protection. But attackers have adapted quickly.

MFA bypass attacks, token theft, session hijacking, and consent phishing campaigns are increasingly targeting healthcare users. As a result, regulators and cybersecurity experts are placing greater emphasis on phishing-resistant authentication approaches and contextual access controls.

For email environments, organizations should increasingly evaluate:

Whether MFA methods are resistant to phishing attacks
Conditional access policies based on device, location, and behavior
Account monitoring and anomaly detection
Administrative access protections
Session management controls
Logging and authentication auditing

The broader message is clear: healthcare organizations need authentication strategies designed for today’s threat landscape, not yesterday’s compliance checklist.

OCR Wants Proof, Not Just Policies

One of the clearest trends emerging from recent OCR activity is the increasing importance of documentation and operational evidence. Healthcare organizations must increasingly demonstrate not only that safeguards exist, but that they are consistently enforced, monitored, tested, and maintained over time.

For email systems, organizations should be prepared to demonstrate:

Email encryption policies
MFA enforcement records
Audit logs and message tracking
Vendor security documentation
Risk assessments involving email infrastructure
Patch management procedures
Employee security awareness training
Incident response procedures for email-based threats

This represents a broader shift in healthcare cybersecurity expectations.

The question is no longer: “Do you have email security controls?”

The question is increasingly: “Can you prove they are operationally effective?”

Healthcare Organizations Need a New Email Security Strategy

The healthcare industry is entering a new phase of cybersecurity enforcement.

OCR’s direction is becoming increasingly clear: organizations are expected to proactively secure systems handling PHI using modern, documented, and continuously maintained safeguards. For email security specifically, that means organizations should stop treating encryption, MFA, and secure communications as optional compliance requirements. Instead, they should view secure email infrastructure as a strategic component of enterprise cybersecurity and patient trust.

At LuxSci, we help healthcare organizations modernize secure communications with HIPAA compliant email infrastructure designed specifically for healthcare environments, including flexible encryption, secure delivery, auditability, high deliverability, access controls, and dedicated infrastructure options.

The proposed HIPAA Security Rule updates may not yet be final. But, OCR is already signaling where healthcare cybersecurity enforcement is headed next. For organizations relying on email to communicate with patients, members, customers, and partners, the time to examine your secure email infrastructure is now.

What Is HIPAA Compliant Email Software?

May 6, 2025
Erik Kangas

HIPAA compliant email software is a specialized communication platform that protects electronic Protected Health Information (ePHI) through encryption, access controls, audit logging, and administrative safeguards required by the HIPAA Security Rule. The software incorporates technical, administrative, and physical safeguards to ensure that patient information transmitted via email meets federal privacy and security standards. Healthcare organizations use this software to communicate securely with patients, providers, and business partners while maintaining compliance with HIPAA regulations and avoiding costly violations. Healthcare providers need secure email solutions that balance operational efficiency with regulatory requirements. Understanding the features and capabilities of HIPAA compliant email software helps organizations select platforms that protect patient privacy while supporting clinical workflows and administrative operations.

Why Organizations Need HIPAA Compliant Email Software

Healthcare organizations need HIPAA compliant email software to meet federal security requirements while maintaining efficient communication channels. Standard email platforms lack the security controls and audit capabilities required to protect ePHI during transmission and storage. The HIPAA Security Rule mandates that covered entities implement administrative, physical, and technical safeguards to protect patient information, making specialized email software necessary for compliance. Data breach statistics highlight the risks of using non-compliant email systems. The Department of Health and Human Services Office for Civil Rights reported that email-related breaches accounted for numerous incidents affecting millions of patients in recent years. Organizations using standard email platforms face increased vulnerability to cyberattacks, unauthorized access, and accidental disclosure of patient information. HIPAA compliant email software reduces these risks through built-in security features and automated protection mechanisms.

Cost considerations also drive the adoption of compliant email software. HIPAA violations can result in fines ranging from $137 to over $2 million per incident, depending on the severity and scope of the breach. The financial impact of data breaches ranges from regulatory fines to include legal costs, remediation expenses, and reputation damage. Investing in HIPAA compliant email software helps organizations avoid these costs while showing commitment to patient privacy and regulatory compliance.

Features of the Best HIPAA Compliant Email Software

Access control features form the foundation of HIPAA compliant email software by ensuring that only authorized users can access patient information. The software implements user identification through individual login credentials, role-based access permissions, and automatic session termination after periods of inactivity. Multi-factor authentication adds further security by requiring users to provide multiple forms of verification before accessing the system. Encryption capabilities protect ePHI both in transit and at rest within the email system. HIPAA compliant email software uses advanced encryption standards to convert readable patient information into coded format that unauthorized parties cannot decrypt. The software encrypts messages during transmission between email servers and maintains encryption when storing messages in the system. End-to-end encryption ensures that only intended recipients can view the content of healthcare communications.

Audit logging functionality tracks all system activity to create detailed records of who accessed patient information, when access occurred, and what actions were performed. The software generates audit trails that include login attempts, message delivery events, encryption status, and user permissions changes. Healthcare organizations can review these logs to identify potential security incidents, investigate unauthorized access attempts, and demonstrate compliance during regulatory inspections.

Data backup and recovery features protect against information loss while maintaining HIPAA compliance throughout the process. The software automatically creates secure backups of email communications and stores them in encrypted format. Recovery procedures ensure that patient information can be restored quickly after system failures while maintaining all security protections. Backup systems include geographic redundancy to protect against natural disasters and other catastrophic events.

HIPAA Compliant Email Software & BA Requirements

Business Associate Agreements (BAAs) create legal frameworks that define how email software vendors protect patient information on behalf of healthcare organizations. HIPAA compliant email software providers willingly sign BAAs and accept responsibility for implementing appropriate safeguards to protect ePHI. The agreements specify security requirements, breach notification procedures, and audit rights that allow healthcare organizations to verify vendor compliance with HIPAA regulations.

Vendor compliance certifications provide additional assurance that email software meets industry security standards. Many HIPAA compliant email software providers undergo third-party security audits and obtain certifications such as SOC 2 Type II, HITRUST CSF, or ISO 27001. These certifications validate that the vendor has implemented appropriate controls to protect customer data and maintain compliance with applicable regulations.

Data processing and storage practices within the best HIPAA compliant email software align with HIPAA requirements for protecting patient information. Vendors implement data segregation to ensure that each healthcare organization’s information remains separate and secure. The software includes features for data retention management, allowing organizations to comply with legal requirements for maintaining patient records while securely disposing of information when retention periods expire.

Incident response procedures within the software help healthcare organizations meet HIPAA breach notification requirements. The system monitors for potential security incidents and provides automated alerts when suspicious activity is detected. When breaches occur, the software facilitates rapid investigation and documentation of the incident, helping organizations meet the 60-day notification requirement for reporting breaches to the Office for Civil Rights.

Support of Administrative Features

Policy management tools within HIPAA compliant email software help healthcare organizations implement and enforce email security policies. The software allows administrators to configure automatic encryption rules, data loss prevention policies, and message retention schedules. Users receive automated notifications when attempting to send emails that may contain patient information without proper encryption or to unauthorized recipients.

User training and awareness features help healthcare organizations educate staff about proper email security practices. The software can include training modules, security reminders, and policy acknowledgment requirements. Some platforms integrate with learning management systems to track training completion and ensure that all users understand their responsibilities for protecting patient information.

Workflow integration capabilities allow HIPAA compliant email software to work seamlessly with existing healthcare systems and processes. The software can integrate with electronic health record systems, practice management platforms, and other healthcare applications. Integration reduces the complexity of sending secure communications and helps ensure that patient information flows securely between different systems within the organization.

Reporting and analytics features provide healthcare organizations with insights into email security practices and compliance status. The software generates reports on encryption usage, policy violations, and user behavior patterns. Healthcare administrators can use this information to identify training needs, adjust security policies, and demonstrate compliance efforts to regulators and auditors.

Evaluating HIPAA Compliant Email Software

Security assessment criteria help healthcare organizations evaluate whether email software meets their specific compliance requirements. Organizations examine encryption methods, access control mechanisms, audit logging capabilities, and data protection features. The evaluation process includes reviewing vendor security documentation, conducting security questionnaires, and assessing the software’s ability to integrate with existing security infrastructure.

Usability considerations play a crucial role in software selection because complex systems can lead to user resistance and workaround behaviors that compromise security. Healthcare organizations evaluate user interface design, mobile device support, and integration with existing workflows. The software needs to provide security without creating barriers that prevent healthcare workers from communicating effectively with patients and colleagues.

Scalability requirements vary based on organization size and growth projections. Healthcare organizations assess whether the email software can accommodate current user counts and expand to meet future needs. Evaluation criteria include storage capacity, user licensing models, and performance under increasing email volumes. The software architecture needs to maintain security and compliance capabilities as the organization grows.

Cost analysis encompasses both direct software expenses and indirect implementation costs. Healthcare organizations compare subscription fees, setup costs, training expenses, and ongoing maintenance requirements. The evaluation includes calculating return on investment based on avoided compliance violations, reduced security incidents, and improved operational efficiency.

Implementation Challenges

User adoption challenges arise when healthcare staff resist changing from familiar email systems to new HIPAA compliant platforms. Staff members may perceive the new software as more complex or time-consuming than their current email applications. Organizations address adoption challenges through change management programs, hands-on training sessions, and clear communication about the benefits of secure email communications.

Integration complexity can create technical difficulties when connecting HIPAA compliant email software with existing healthcare systems. Different software platforms may use incompatible data formats, authentication methods, or communication protocols. Organizations need to plan integration projects carefully and may require technical assistance from vendors or third-party consultants to ensure seamless connectivity.

Migration planning involves transferring existing email communications and configurations to the new HIPAA compliant platform. Healthcare organizations need to develop procedures for moving historical email data while maintaining security protections throughout the migration process. The transition period requires careful coordination to avoid disrupting patient care or administrative operations.

Performance optimization is highly important as healthcare organizations implement HIPAA compliant email software across large user bases. Email volumes in healthcare settings can be substantial, particularly in hospital systems or large medical practices. Organizations need to monitor system performance and work with vendors to optimize configurations that maintain both security and responsiveness under peak usage conditions.

Email Marketing Best Practices for Healthcare

November 14, 2023
Pete Wermter

Email marketing can be a powerful tool for healthcare organizations, but it requires careful planning and execution because of HIPAA compliance requirements. In this blog post, we will discuss email marketing best practices to help healthcare marketers achieve their goals.

1. Define Your Campaign Goals

The success of any email marketing campaign depends on the goals you want to achieve. However, because healthcare organizations are often not selling products to their patients, marketers can be confused about how to set measurable goals for their campaigns that aren’t tied to revenue generation.

Healthcare marketers want to use email marketing campaigns for various purposes, including patient engagement, education, and retention. Some possible objectives of your campaigns could be:

New patient acquisition
Re-engaging lapsed patients
Spreading awareness about vaccines, treatments, or medical conditions
Increasing treatment or medication adherence
Collecting survey responses or patient-reported outcomes

All of these campaign objectives will correlate with different metrics. Identifying the campaign goal and the corresponding metrics you need to track is critical before selecting the audience and crafting the content.

2. Select Your Audience

Gone are the days of sending giant email blasts to your entire contact list. The best email marketers are creating highly targeted campaigns for specific audiences. Healthcare marketers using patient data in their audience targeting efforts are at an advantage. They can use patient information to create distinct audience segments. Targeting a patient population with common attributes makes it easier to craft a relevant message to drive clear results. For example, marketers can create more relevant campaigns when they can divide their patient population into subgroups based on shared characteristics like diagnoses, risk factors, and demographic data.

3. Personalize Your Content

Once you have clearly defined your goal and your audience, it’s essential to use personalization techniques to craft relevant messaging. Healthcare consumers expect more personalization from their providers and want to receive messages that tie into their past experiences. Generic, irrelevant messaging is more likely to annoy patients than get them to act. Healthcare marketers are lucky to have a wealth of data points to use in their messaging, but they must be aware of patient privacy and take steps to secure their messaging. When you have taken the appropriate steps to secure patient data, including protected health information in email messages is possible. This improves the patient experience and makes it easier for healthcare marketers to achieve their objectives.

4. Use A Clear Call-to-Action

Your emails should include a clear call-to-action (CTA) that encourages your audience to take the desired action. These actions may include scheduling an appointment, downloading a resource, logging into a patient portal, filling out a survey, or contacting your organization. Ensure that your CTA is prominent, stands out from the rest of your content, and ties back to the goal of your campaign. Most importantly, implement appropriate tracking technologies so you can see how many email recipients followed through on the CTA.

Don’t include too many calls to action in one message! Including multiple prompts may confuse the recipient and make it more difficult for your team to understand how the campaign performed.

5. Review Your Data

Finally, it’s essential to monitor your email metrics to evaluate the success of your campaigns. Some key metrics may include open rates, click-through rates, surveys completed, successful logins, appointments scheduled, and other relevant metrics that tie back to your goals. Use this data to refine your email marketing strategy, trigger follow-up campaigns and marketing activity, and optimize future campaigns. Use APIs or webhooks to ensure your email campaign statistics are tied into marketing dashboards to get a holistic view of how your campaigns are performing.

6. Choose an Email Marketing Platform Designed for Healthcare

Finally, to use the tactics recommended above, it’s necessary to use a HIPAA-compliant email marketing platform. Segmenting audiences and personalizing content requires the use of protected health information. Therefore, it must be secured in compliance with HIPAA. You must select a platform that can protect data both at rest and in transit to utilize the power of your data fully.

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.

What Is the Best HIPAA Compliant Email Software?

October 16, 2025
Erik Kangas

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.
