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

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

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

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

LuxSci vs. Paubox: Evaluation Criteria

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

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

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

LuxSci vs. Paubox: How They Compare

Data Security and Compliance

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

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

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

Performance and Scalability

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

Infrastructure

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

Marketing capabilities

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

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

Ease of use

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

Other HIPAA-compliant Products

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

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

HIPAA Security Rule Email Encryption Requirements

July 8, 2026

Your Email Platform Is Becoming Critical Healthcare Infrastructure

July 1, 2026
Pete Wermter

Most healthcare organizations view email as a utility, a necessary tool for sending messages between staff, communicating with patients, sending out newsletters, connecting workflows, and so on. Historically, IT teams focused on keeping it running, security teams worried about phishing, and compliance teams made sure sensitive emails were encrypted.

Today, however, that view is rapidly becoming outdated.

Email has evolved into one of healthcare’s most critical digital infrastructure components, and also one of it’s biggest security threats. It’s a core channel for patient engagement, care coordination, revenue cycle operations, digital marketing, remote monitoring, and increasingly, AI-powered communications. The organizations that recognize this shift are building communications platforms designed for security, performance, automation, and growth. With the new HIPAA Security Rule requiring email encryption on the horizon, those companies that don’t may find themselves constrained by systems that were never intended to support modern healthcare.

Email Is No Longer Just a Messaging Tool

Healthcare organizations now depend on email to support dozens of mission-critical workflows every day.

Patients receive appointment reminders, registration instructions, imaging results, billing notifications, Explanation of Benefits (EOBs), prescription updates, preventive care reminders, patient education, and post-discharge follow-up. Marketing teams deliver personalized wellness campaigns and service line promotions. Clinical systems generate transactional notifications. Revenue cycle teams rely on secure digital communications to accelerate payments and reduce paper costs.

For many organizations, mission-critical patient communications flow through email every month.

When viewed collectively, email is more than a simple communications channel. It has become operational infrastructure with high levels of security needed and increasing compliance requirements.

The Stakes Continue to Rise

As healthcare becomes more digital, every communication carries greater business and clinical importance.

A delayed billing email may postpone payment. A failed appointment reminder can increase no-show rates. An undelivered care management message may impact patient outcomes. A misconfigured security policy can expose protected health information (PHI). Poor deliverability can undermine expensive patient engagement initiatives before they ever reach the inbox.

These are no longer isolated IT issues. Email can affect revenue, patient satisfaction, operational efficiency, compliance, and organizational reputation.

Today’s healthcare leaders require email infrastructure to provide the same reliability and visibility they demand from electronic health records, identity management systems, and other core infrastructure.

AI Is Raising the Bar Even Higher

There’s little doubt that artificial intelligence (AI) promises to transform patient communications.

Healthcare organizations everywhere are exploring AI-generated patient education, personalized outreach, intelligent scheduling, multilingual communications, and automated follow-up programs.

But AI also increases the importance of the underlying communications infrastructure.

Generating more personalized emails means little if organizations cannot:

Automatically protect PHI.
Apply consistent security policies.
Maintain complete audit trails.
Deliver messages reliably.
Integrate with EHRs, RCM and CRM platforms, and customer data platforms.
Demonstrate compliance during an audits.

In many ways, AI amplifies both the opportunities and the risks. Your email platform can help determine whether AI initiatives succeed or create new compliance and operational challenges.

Infrastructure Matters More Than Features

Healthcare buyers have traditionally evaluated email platforms based on individual features such as encryption, spam filtering, or secure portals.

Those capabilities remain important, but they no longer tell the whole story.

Today’s healthcare organizations should be evaluating communications platforms the same way they evaluate any mission-critical infrastructure.

Questions increasingly include:

Can it support both transactional and marketing communications?
Does it automatically enforce security policies without relying on user decisions?
Can it integrate with EHRs, CRM systems, CDPs, and business applications?
Will it scale during peak communication periods?
Does it provide detailed audit logging and reporting?
Can it adapt as regulatory expectations evolve?
Does it maintain high deliverability at enterprise scale?
Does it support single-tenant dedicated infrastructure for high performance and increased security?

These infrastructure characteristics often determine long-term success far more than any single feature comparison.

Email and the Future Of Secure Healthcare Communications

Healthcare is steadily moving toward a world where nearly every patient interaction is digital, personalized, and data-driven.

Healthcare leaders often ask whether they need a more secure email solution. That may be the wrong question.

The better question is whether their communications infrastructure is ready for where healthcare is headed over the next decade.

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. Our HIPAA-compliant solutions for secure email, email marketing, and forms empower organizations to safely use and protect PHI, while delivering better patient experiences and outcomes.

Is Mailchimp HIPAA Compliant?

October 10, 2024
LuxSci

The question “Is Mailchimp HIPAA-compliant?” has echoed across healthcare companies and organizations countless times. Whenever they explore their options for email automation and marketing software, the popular provider’s name tends to be one of the first to pop up.

Offering an integrated email marketing solution that enables businesses to streamline how they connect with their customers, Mailchimp has long been the go-to option for companies looking to improve their engagement efforts.

With healthcare organizations using the platform to distribute emails, send newsletters, share content on their social channels, track their results and more, it’s only natural that these companies are also wondering whether Mailchimp HIPAA-compliant bulk email is possible.

IS MAILCHIMP HIPAA COMPLIANT?

Unfortunately, the answer will disappoint many in the healthcare sector, as well as other businesses and companies that deal with electronic protected health information (ePHI): Mailchimp is not HIPAA-compliant.

Despite this, however, the platform does have some promising security features and policies that make it seem as though Mailchimp could be a HIPAA-compliant marketing email option, including:

Login pages encrypted with Transport Layer Security (TLS)
Hashed password storage and brute-force protection, which prevent malicious actors from attempting to log in with every possible password.
Regular penetration tests and security audits.

Now, while these security features are certainly encouraging, there is a significant omission that prevents Mailchimp from being a HIPAA-compliant email provider.

MAILCHIMP: NO BUSINESS ASSOCIATE AGREEMENT

According to the HIPAA Privacy Rule, “A business associate is a person or organization that performs certain functions or activities that involve the use or disclosure of protected health information (PHI) by a covered entity”.

In the context of a HIPAA-compliant email provider, Mailchimp would be the business associate and the healthcare organization would be the covered entity.

Subsequently, a business associate agreement (BAA) is a written contract between a covered entity and a business associate that is essential for HIPAA compliance. It details how two organizations can share data and under what circumstances. A BAA also delineates where the legal responsibilities of each party fall and who will be culpable if there are any problems.

BAAs are a critical part of HIPAA compliance and failure to have one is considered an immediate HIPAA violation. It doesn’t matter if all security best practices are being followed, and the ePHI is shared in a manner that’s compliant in every other way – sharing data without a BAA in place is still a violation.

If a company puts in the extra effort to provide a HIPAA-compliant service, it will generally advertise its compliance to attract more clients from the health sector. In the case of Mailchimp – there is hardly a mention of a BAA on its website.

Additionally, Section 21 of MailChimp’s Terms of Use states, “You’re responsible for determining whether the Service is suitable for you to use in light of your obligations under any regulations like HIPAA, GLBA … If you’re subject to regulations (like HIPAA) and you use the Service, then we won’t be liable if the Service doesn’t meet those requirements.”

In other words, in contrast to a BAA, Mailchimp is transparent and clear on squarely placing the responsibility of non-compliance on the healthcare organization – even mentioning HIPAA by name.

Besides the absence of a BAA, Mailchimp also does not make any provision for encrypting the bulk emails that would be sent out from its platform. This makes it unsuitable for sending HIPPA-compliant emails. On top of this, Mailchimp lacks many other security nuances, which wouldn’t be required unless you have to follow HIPAA or other compliance frameworks.

In conclusion, the only answer to “Is Mailchimp HIPAA-compliant?” is a resounding “No”.

MAILCHIMP HIPAA-COMPLIANT ALTERNATIVES

Fortunately, all is not lost for healthcare companies that need a HIPAA-compliant bulk email or high volume email solution, or other HIPAA-compliant marketing tools. While they may have to rule out popular options like Mailchimp, there are several HIPAA-compliant email services that are specifically designed for organizations that have to comply with the regulations.

As the most experienced HIPAA-compliant email provider, LuxSci specializes in providing secure and HIPAA-compliant services for companies aiming to send hundreds of thousands – or even millions – of emails to patients and customers. In light of this, we place security, regulatory and customer considerations front and center when delivering our solutions.

Our approach combines the most experience in HIPAA-compliant communications with a suite of secure solutions, including HIPAA-compliant high volume email and HIPAA-compliant email marketing. Our flexible encryption and multi-channel approach to secure healthcare communications enables healthcare companies to strike the right balance between security and regulatory concerns, and communicating with patients and customers over the channel of their choice for better outcomes.

How Can Healthcare Organizations Find Free HIPAA Email Solutions?

July 11, 2025
Erik Kangas

Free HIPAA email solutions do not exist for healthcare organizations despite claims from various platforms and open-source projects that appear to offer no-cost compliance options. Healthcare providers seeking truly compliant email communication discover that platforms like Gmail, Yahoo, and other consumer email services cannot provide the Business Associate Agreements, encryption controls, and audit capabilities required for patient data protection. Most healthcare practices learn that attempting to use free HIPAA email platforms for PHI communications creates substantial compliance risks and potential regulatory violations that far exceed the cost savings of avoiding purpose-built healthcare email solutions.

Why Consumer Platforms Cannot Provide Free HIPAA Email

Gmail and other consumer email platforms explicitly refuse to sign Business Associate Agreements with healthcare organizations, making them unsuitable for any communications containing protected health information. Google’s Terms of Service specifically prohibit healthcare organizations from using personal Gmail accounts for patient communications, and even Google Workspace requires careful configuration and additional security measures that eliminate any cost savings from “free” accounts.

Consumer email platforms lack the audit logging capabilities required for HIPAA compliance, making it impossible for healthcare organizations to track access to patient communications or investigate potential security incidents. These platforms prioritize convenience and broad compatibility over the stringent security controls that healthcare organizations need to protect patient data during email transmission and storage.

Open Source Solutions Create Hidden Compliance Costs

Open-source email servers like Zimbra and Postfix may appear cost-effective but require extensive technical expertise and ongoing maintenance that healthcare organizations rarely possess internally. Implementing proper HIPAA compliance with open-source platforms demands specialized knowledge of encryption protocols, access controls, and audit logging that most medical practices cannot develop or maintain cost-effectively.

Security vulnerabilities in self-managed email systems create liability risks that healthcare organizations cannot afford to ignore. Without dedicated security teams to monitor threats and apply patches, open-source email installations become attractive targets for cybercriminals seeking access to valuable patient data. The cost of a single data breach far exceeds any savings from avoiding commercial email solutions.

BAA Requirements Eliminate Free HIPAA Email Options

HIPAA compliance requires healthcare organizations to obtain signed Business Associate Agreements from any vendor that handles protected health information, including email service providers. Free HIPAA email platforms and open-source solutions cannot provide the legal protections and liability coverage that proper BAAs require, leaving healthcare organizations exposed to regulatory penalties and lawsuit risks.

Most free HIPAA email providers explicitly disclaim responsibility for HIPAA compliance in their terms of service, shifting all liability to healthcare organizations that choose to use their platforms. This liability transfer makes free HIPAA email platforms unsuitable for healthcare communications regardless of their technical capabilities or security features.

The False Economy of Cheap Email Solutions

Healthcare organizations that prioritize cost savings over compliance capabilities often discover that cheap email solutions create expensive problems. Inadequate security controls, poor audit trails, and limited support options lead to compliance gaps that regulatory audits easily identify and penalize heavily.

Staff productivity suffers when healthcare workers struggle with poorly designed interfaces, unreliable service, or inadequate mobile access that cheap email solutions provide. The time lost to system problems and workarounds quickly eliminates any cost advantages from selecting budget email platforms over purpose-built healthcare communication tools.

Compliance Gaps Create Regulatory and Financial Risks

Healthcare organizations using inappropriate email solutions face potential HIPAA penalties ranging from thousands to millions of dollars depending on the scope and severity of compliance violations. OCR investigations frequently identify email security deficiencies as contributing factors in data breaches that result in significant financial penalties and mandatory corrective action plans.

Patient trust erosion from email security incidents can damage healthcare organizations’ reputations and reduce patient volumes over time. The long-term financial impact of lost patients and reduced referrals often exceeds the cost difference between free and compliant email solutions by substantial margins.

Limitations Prevent Proper PHI Protection

Free HIPAA email platforms cannot provide the granular access controls that HIPAA compliance requires for protecting different types of patient information. Healthcare organizations need the ability to restrict access to sensitive communications based on staff roles and clinical responsibilities, capabilities that consumer email platforms do not support.

Encryption limitations in free HIPAA email services prevent healthcare organizations from ensuring that patient data receives appropriate protection during transmission and storage. Many free platforms offer basic encryption that falls short of healthcare security standards or provide encryption that healthcare organizations cannot control or verify independently.

Support Deficiencies Create Operational Risks

Free email platforms provide minimal technical support that cannot address the urgent security incidents and system problems that healthcare organizations face. When email systems fail or security breaches occur, healthcare providers need immediate expert assistance that free platforms cannot provide through standard support channels.

Compliance guidance from email vendors helps healthcare organizations navigate complex regulatory requirements and implement proper security controls. Free HIPAA email platforms cannot offer the specialized compliance expertise that healthcare organizations need to maintain proper HIPAA adherence and respond appropriately to regulatory inquiries.

Migration Costs Offset Initial Savings

Healthcare organizations that initially choose free HIPAA email / cheap email solutions eventually face expensive migration projects when they discover compliance inadequacies or operational limitations. Moving years of email archives and reconfiguring integrated systems creates substantial costs that proper initial platform selection could have avoided.

Staff retraining requirements for multiple email platform changes create productivity losses and resistance to new systems that affect overall operational efficiency. Healthcare organizations benefit from selecting appropriate email solutions initially rather than cycling through multiple inadequate platforms over time.

Investment in Proper Email Solutions Provides Long-Term Value

Purpose-built healthcare email platforms provide compliance capabilities, security controls, and operational features that justify their costs through reduced regulatory risks and improved staff productivity. The total cost of ownership for compliant email solutions often proves lower than seemingly cheaper alternatives when organizations account for all implementation, maintenance, and risk factors.

Healthcare organizations that invest in proper email infrastructure from the beginning avoid the disruption and expense of multiple platform changes while maintaining consistent compliance posture throughout their growth and evolution. Reliable email communication supports better patient care and more efficient operations that contribute to organizational success over time.

What Is The Best Secure Email Provider For Healthcare Organizations?

June 12, 2025
Erik Kangas

The best secure email provider for healthcare organizations offers end-to-end encryption, HIPAA compliance features, audit logging capabilities, and integration options that meet the specific communication needs of providers, payers, and suppliers handling protected health information. Healthcare organizations need email solutions that protect patient data during transmission and storage while maintaining usability for clinical and administrative workflows. Finding the best secure email provider requires evaluating security features, compliance capabilities, integration options, user experience, and total cost of ownership across different platform types.

Security Features That Define The Best Secure Email Provider

The best secure email provider implements multiple layers of security protection to safeguard healthcare communications from unauthorized access and cyber threats. End-to-end encryption protects messages and attachments during transmission, ensuring that only intended recipients can decrypt and read email content. Transport Layer Security protocols secure connections between email servers, while message-level encryption protects content even when stored on email servers. Multi-factor authentication verifies user identities before granting access to email systems, requiring additional verification beyond standard passwords to prevent unauthorized account access. Access controls allow administrators to define which users can send emails to external recipients and specify what types of information can be included in different message categories. Data loss prevention features scan outgoing emails for protected health information and apply appropriate security measures or block transmission of potentially sensitive content.

HIPAA Compliance Capabilities And Administrative Controls

Administrative tools specifically designed for healthcare organizations help maintain HIPAA compliance while managing email communications efficiently. Centralized administration allows IT teams to configure security policies, manage user permissions, and monitor compliance across the entire organization from a single interface. Role-based access controls ensure that staff members can only access email functions appropriate to their job responsibilities. Automated policy enforcement applies security settings based on message content, recipient types, and organizational rules without requiring manual intervention from users. The best secure email provider generates compliance reports that demonstrate adherence to HIPAA requirements and provide documentation for regulatory audits. Business associate agreement templates help healthcare organizations establish appropriate contractual relationships with their email service providers.

Integration Options With Healthcare Systems

The best secure email provider integrates seamlessly with electronic health record systems, practice management platforms, and other healthcare applications to minimize workflow disruptions. Application programming interfaces enable custom integrations that allow users to send secure emails directly from patient records or billing systems without switching between multiple platforms. Single sign-on capabilities let users access email functions using their existing healthcare system credentials.

Integration with patient portal systems enables secure two-way communication between healthcare organizations and their patients through familiar interfaces. Automated triggers generate secure email notifications for appointment reminders, lab results, billing communications, and other routine patient interactions. Mobile device integration allows healthcare professionals to access secure email communications from smartphones and tablets while maintaining security protections.

User Experience And Patient Communication Features

Balancing security requirements with user-friendly interfaces encourages adoption and proper use across healthcare organizations. Intuitive design reduces training requirements and helps staff members quickly learn to use secure email features effectively. Message composition tools make it easy to create compliant emails with appropriate security settings without requiring extensive technical knowledge.

Patient communication features enable healthcare organizations to send secure messages that patients can access through user-friendly portals or secure email clients. Patient-facing interfaces work well for individuals with varying levels of technical expertise and diverse communication preferences. Message delivery confirmation and read receipts help healthcare staff verify that important communications reached intended recipients and were accessed appropriately.

Cost Considerations And Deployment Models

Flexible pricing models accommodate different organizational sizes and usage patterns while providing predictable costs for budget planning. Per-user subscription models allow healthcare organizations to scale email security based on their actual workforce size and communication needs. Cloud-based deployment reduces infrastructure costs and maintenance requirements while providing enterprise-grade security features.

Implementation costs include initial setup, data migration, staff training, and system integration expenses that should be factored into total cost evaluations. Return on investment calculations should consider potential savings from avoiding HIPAA violation penalties, reduced risk of data breaches, and improved operational efficiency from streamlined secure communication processes. Long-term cost analysis includes subscription fees, storage costs, and upgrade expenses that affect ownership calculations.

Evaluation Criteria For Selecting The Best Secure Email Provider

Healthcare organizations should evaluate potential secure email providers based on their specific communication patterns, technical infrastructure, regulatory requirements, and budget constraints. Security assessment criteria include encryption methods, access controls, audit capabilities, and threat protection features that address the organization’s risk profile. Compliance evaluation should verify that providers maintain appropriate certifications, business associate agreements, and documentation to support HIPAA compliance efforts.

Feature comparison helps identify which platforms offer the integration options, user experience elements, and administrative tools needed for specific use cases. Reference checks with similar healthcare organizations provide insights into real-world performance, implementation experiences, and ongoing support quality. Decision frameworks that consider security requirements, usability needs, integration capabilities, and budget constraints help organizations select secure email solutions that will serve their communication and compliance objectives effectively.

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.
