SMTP TLS encryption is popular because it provides adequate data protection without creating a complicated user experience for email recipients. Sometimes, though, the experience is too seamless, and recipients may wonder if the message was protected at all.

Luckily, there is a way to tell if an email was encrypted using TLS. To see if a message was sent securely, we can look at the raw headers of the email. However, it requires some knowledge and experience to understand the text. It is actually easier to tell if a recipient’s server supports TLS than to tell if a particular message was securely transmitted.

To analyze a message for transmission security, we will look at an example email message sent from Hotmail to LuxSci. We will explain what to look for when decoding the message headers and how to tell if the email was transmitted using TLS encryption.

An Example Email Message

First, we must understand how an email message typically travels through several machines on its way from the sender to the recipient. Roughly speaking:

The sender’s computer talks to the sender’s email or WebMail server to upload the message.
The sender’s email or WebMail server then talks to the recipient’s inbound email server and transmits the message to them.
Finally, the recipient downloads the message from their email server.

It is step 2 that people are most concerned about when trying to understand if their email message is transmitted securely. They usually assume or check that everything is secure and OK at the two ends. Indeed, most users who need to can take steps to ensure that they are using SSL-enabled WebMail or POP/IMAP/SMTP/Exchange services so that steps 1 and 3 are secure. The intermediate step, where the email is transmitted between two different providers, is where messages may be sent insecurely.

To determine if the message was transmitted securely between the sender’s and recipient’s servers (over TLS), we need to extract the “Received” header lines from the received email message. If you look at the source of the email message, the lines at the top start with “Received.” Let’s look at an example message from a Hotmail user below. The email addresses, IPs, and other information are obviously fake.

LuxSci:

The Outlook email was sent to a LuxSci user. The Received headers appear in reverse chronological order, starting with the server that touched the message last. Therefore, in this example, we see the LuxSci servers first.

Received: from abc.luxsci.com ([1.1.1.1])
	by def.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfLgH003867
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 10:41:21 -0400
Received: from abc.luxsci.com (localhost.localdomain [127.0.0.1])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfK0Z030182
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 09:41:20 -0500
Received: (from mail@localhost)
	by abc.luxsci.com (8.14.4/8.13.8/Submit) id r7JEfKXD030178
	for user-xyz@def.luxsci.com; Mon, 19 Aug 2019 09:41:20 -0500

Received: from dispatch1-us1.ppe-hosted.com (dispatch1-us1.ppe-hosted.com [2.2.2.2])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfIkK030002
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <someone@luxsci.net>; Mon, 19 Aug 2019 09:41:19 -0500

Proofpoint:

LuxSci uses an email filtering service, Proofpoint. Messages reach Proofpoint’s servers before being delivered to LuxSci. Here’s what their servers report about the email transmission:

Received: from unknown [65.54.190.216] (EHLO bay0-omc4-s14.bay0.hotmail.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (envelope-from <someone@hotmail.com>);
	Mon, 19 Aug 2019 08:41:18 -0600 (MDT)

Outlook:

And finally, here’s what we see from Oultook’s server.

Received: from BAY403-EAS373 ([65.54.190.199]) by bay0-omc4-s14.bay0.outlook.com
       with Microsoft SMTPSVC(6.0.3790.4675); 
       Mon, 19 Aug 2019 07:41:19 -0700

How to Use Received Message Headers to Tell if the Email is Encrypted

The message headers contain information that can help us determine if an email is encrypted. Here are a few helpful notes to help you decode the text:

We said this above, but the message headers appear in reverse chronological order. The first one listed shows the last server that touched the message; the last one is the first server that touched it (typically the sending server).
Each Received line documents what a server did and when.
There are three sets of servers involved in this example: one machine at Hotmail, one machine at Proofpoint, where our Premium Email Filtering takes place, and some machines at LuxSci, where final acceptance of the message and subsequent delivery happened.

Presumably, the processing of email within each provider is secure. The place to be concerned about is the hand-offs between Hotmail and Proofpoint and between Proofpoint and LuxSci, as these are the big hops across the internet between providers.

In the line where LuxSci accepts the message from Proofpoint, we see:

(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)

This section, typical of most email servers running “sendmail” with TLS support, indicates that the message was encrypted during transport with TLS using 256-bit AES encryption. (“Verify=not” means that LuxSci did not ask Proofpoint for a second SSL client certificate to verify itself, as that is not usually needed or required for SMTP TLS to work correctly). Also, “TLSv1/SSLv3” is a tag that means that “Some version of SSL or TLS was used;” it does not mean that it was SSL v3 or TLS v1.0. It could have been TLS v1.2 or TLS v1.3.

So, the hop between Proofpoint and LuxSci was locked down and secure. What about the hop between Hotmail and Proofpoint? The Proofpoint server’s Received line makes no note of security at all! This means that the email message was probably not encrypted during this step.

Hotmail either did not support opportunistic TLS encryption for outbound emails, or Proofpoint did not support receipt of messages over TLS, and thus, TLS could not be used. With additional context, you can know which server supports TLS and which does not.

In this case, we know that Proofpoint supports inbound TLS encryption. In fact, from another example message where LuxSci sent a message to Proofpoint, we see the Received line:

Received: from unknown [44.44.44.44] (EHLO wgh.luxsci.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits))
	with ESMTP id b-022.p01c11m003.ppe-hosted.com
        (envelope-from <from@domain.com>);
	Mon, 02 Feb 2009 19:28:27 -0700 (MST)

The red text makes it clear that the message was indeed encrypted. Based on the additional context, we can deduce that the Hotmail sending server did not securely transmit the email using TLS.

How To Tell if an Email is Encrypted With TLS

When analyzing your message headers, consider the following items to determine if the email is encrypted:
1. The receiving server will log what kind of encryption, if any, was used in receiving the message in the headers.
2. Different email servers use different formats and syntax to display the encryption used. Look for keywords like “SSL,” “TLS,” and “Encryption,” which will signify this information.
3. Not all servers will record the use of encryption. While LuxSci has always logged encryption use, not every email service provider does. It is possible to use TLS encryption and not log it. Sometimes, there is no way to tell from the headers if a message is encrypted if it is not logged.
4. Messages passed between servers at the same provider do not necessarily need TLS encryption to be secure. For example, LuxSci has back-channel private network connections between many servers so that information can be securely passed between them without SMTP TLS. So, the lack of TLS usage between two servers does not mean the transmission between them was “insecure.” You may also see multiple received lines listing the same server: the server passes the message between different processes within itself. This communication also does not need to be TLS encrypted.
5. If you are a LuxSci customer, you can view online email delivery reports to see if TLS was used for any particular message. We record the kind of encryption in the delivery reports, so it’s easy to see which emails were encrypted.

How can you Ensure Emails Are Securely Transmitted?

With some servers not recording TLS in message headers, how can you determine if a message was transmitted securely from sender to recipient?

To answer this question accurately, you must understand the properties, servers, and networks involved. It may be easy to determine that the message was transmitted securely if included in the header information. However, the absence of information does not necessarily mean the message was insecurely transmitted. You can only know this if you know what each system’s servers record.

In our example of a message from Hotmail to LuxSci, you need to know that:

Proofpoint and LuxSci will always log the use of TLS in the headers. We can infer that the Hotmail to Proofpoint transmission was not secure as nothing was recorded there.
The transmission of messages within LuxSci’s infrastructure is secure due to private back channel transmissions. So, even though there is no mention of TLS in every Received line after LuxSci accepts the message from Proofpoint (in this example), transferring the messages between servers in LuxSci is as secure as using TLS. Also, the same server can add multiple received lines as it talks to itself. Generally, these hand-offs on the same server will not use TLS, as there is no need. In the LuxSci example, we see this as “abc.luxsci.com” adds several headers.
We don’t know anything about Hotmail’s email servers, so we don’t know how secure the initial transmissions within their network are. However, since we know they did not securely transmit the message to Proofpoint, we are not confident that the transmissions and processing within Hotmail (which may have gone unrecorded) were secure.

Was the email message sent and received using encryption?

We skipped steps 1 and 3 and focused on step 2 – the transmission between servers. Steps 1 and 3 are equally, if not more, necessary. Why? Because eavesdropping on the internet between ISPs is less of a problem than eavesdropping near the sender and recipient (i.e., in their workplace or local wireless hotspot). So, it’s essential to ensure messages are sent securely and received securely. This means:

Sending: Use SMTP over SSL or TLS when sending messages from an email client or use WebMail over a secure connection (HTTPS).
Receiving: Ensure your POP or IMAP connection is secured via SSL or TLS. If using WebMail to read your email, be sure it is over a secure connection (HTTPS).
WebMail: There is generally no record in the email headers to indicate if a message sent using WebMail was transmitted from the end-user to WebMail over a secure connection (SSL/HTTPS).

You can typically control one side and ensure it is secure; you can’t control the other without taking extra steps. So, what can you do to ensure your message is secure even if it might not be transmitted with encryption or if the recipient tries to access it insecurely?

You could use end-to-end email encryption (like PGP or S/MIME, which are included in SecureLine) or a secure web portal that doesn’t require the recipient to install or set up anything to get your secure email message. These methods meet HIPAA and other regulatory compliance requirements for secure data transmission and provide complete confidence that the message will be sent and received securely.

LuxSci’s SecureLine offers flexible encryption options, including TLS, secure web portal, PGP, and S/MIME. Its dynamic capabilities can determine what types of encryption the recipient’s server supports to ensure your emails are always sent securely.

What you’ll learn:

Rethinking HIPAA Compliant Email – Not Just a Checkbox

January 20, 2026
Pete Wermter

The compliance-only mentality is outdated.

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

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

What Makes Email Truly HIPAA Compliant?

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

Use encryption at all times

Be access-controlled

Include audit logs

Be stored and transmitted in a secure manner

Provide a Business Associate Agreement

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

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

The Real Opportunity – Secure, Personalized Email with PHI

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

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

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

Real Business Results from Secure Email

Here’s how secure, personalized email can drive improved results across a range of healthcare communications, including:

Increased Patient Appointments and Follow-ups – Sending encrypted, personalized appointment reminders and follow-up notices can reduce no-shows and boost overall appointment volume.
Boosting Preventative Care with Outreach Campaigns – Preventative campaigns (think flu shots or cancer screenings) sent securely to the right segments can lead to higher response rates, better health outcomes, and a lower cost of care.
Improving Health Plan Enrollments – Targeted email outreach during open enrollment, tailored by eligibility or plan type, and powered by automated workflows leads to higher enrollments and lower call center costs.
Driving Awareness and Sales of New Services or Products – Have a product upgrade offer, new wellness program or telehealth service? Send secure, PHI-informed HIPAA compliant email to the right audience for increased sales and faster adoption.
Optimize Explanation of Benefits Notices – Replace snail mail with email that’s fast, reliable and trackable, ensuring customers are informed and compliance is met.

The Healthcare Marketer’s Secret Weapon: Using PHI Responsibly

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

Meeting the Personalization Demands of Today’s Patients and Customers

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

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

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

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

- Building Trust Through Secure Communication – Each secure, personalized message sent is a trust-building moment with your patients and customers.

How Secure Texting for Healthcare Improves Patient Portals

October 3, 2024
LuxSci

Patient portals were once hailed as a game-changing tool for healthcare companies to engage patients throughout their healthcare journey. In theory, they offer a convenient platform where patients and customers can access their medical records, communicate with their providers or suppliers, book appointments, and even pay bills—safely and securely. But despite the optimism around patient portals, the reality is much more complex. Adoption rates remain stubbornly low, and many patients simply don’t like using them.

So, why is this the case? More importantly, how does the relatively mediocre adoption of patient portals impact patient engagement, outcomes, and overall cost?

In this post, we’ll take a closer look at the shortcomings of patient portals, share current trends in patient and customer communication preferences, and explore how text communication can improve portal adoption and patient engagement.

Why Patient Portals Aren’t Enough

At their core, patient portals are online platforms that provide access to a range of healthcare-related services. These services typically include:

Access to medical records
Secure messaging with healthcare providers
Appointment scheduling
Prescription refill requests
Bill payments

These portals were designed with good intentions, but as we’ll discuss, they often fall short of delivering the seamless, user-friendly experience that people expect today.

Preferences for Healthcare Communications

Healthcare communication preferences have shifted. Today’s patients don’t just want portals—they want a range of communication options, from phone calls and emails to secure texts. According to a 2023 survey by Accenture, patients’ preferred communication channels include:

Phone Calls: 62% of patients still prefer phone conversations with their healthcare providers.
Email: 44% like receiving emails for lab results, appointment reminders, and other updates.
Text Messaging: 37% of patients prefer receiving healthcare communications via text, particularly for reminders and follow-ups.
Patient Portals: Only 28% of patients prefer using portals for routine interactions.

There are several reasons why people are reluctant to adopt patient portals, including:

Complexity: Many portals can be clunky, difficult to navigate, and not user-friendly. Patients and customers often find it difficult to log in, locate their information, or contact their provider or supplier through the portal.
Lack of Engagement: Patients are rarely encouraged to use these portals consistently, and some are unaware they even exist.
Concerns About Security: While patient portals are designed to be secure, many patients still harbor concerns about their personal health information being compromised.
Limited Access: Some portals only provide limited access to medical records, appointment scheduling, or other information, making them less useful.

Relying solely on patient portals leaves a significant portion of patients and customers under-served. By integrating secure texting apps into their engagement strategies, healthcare providers, payers and suppliers can diversify their communication methods and connect with patients and customers more effectively across the channels they prefer.

How Secure Texting Complements Patient Portals

Secure texting apps for healthcare solve many of the issues patient portals alone cannot. By offering an additional, patient-friendly communication channel, these apps improve patient engagement and streamline interactions.

Here’s how secure texting apps work:

Secure Access to Patient Portals: Secure texting apps allow patients to access ePHI and other sensitive information directly from mobile devices via regular SMS text messages.
Instant Notifications & Alerts: Patients and customers can click on a link in text messages and view information in a secure mobile web browser on their smartphones or tablets, including appointment reminders, updates, product upgrades and promotions.
User-friendly: Most secure texting apps are designed with usability in mind, offering an intuitive, seamless experience – with no new applications required.

By offering secure texting as an additional communication channel, healthcare organizations can reach more patients and customers, and improve engagement by offering patients multiple channel options for communication and easier access to portals.

Security and HIPAA Compiance

It’s essential to note that not all texting apps are appropriate for healthcare use. Traditional text messaging services don’t offer the level of encryption and security required by HIPAA regulations, making them risky for exchanging protected health information (PHI).

LuxSci’s secure texting for healthcare ensures that patient and customer communications comply with HIPAA’s strict privacy and security standards. Our secure texting solution offers encryption, authentication, and data protection, ensuring that patients can directly and safely access portals for viewing health information, treatment plans, payments, promotions and more.

Benefits of Secure Texting for Healthcare

Adopting secure texting apps for healthcare, alongside other communication tools, including email and web forms, brings numerous benefits to both patients and providers, including:

Increased Engagement: Patients and customers are more likely to respond and engage with providers through their preferred communication method, not just a portal.
Improved Outcomes and Results: Engaged patients are more likely to adhere to their treatment plans, stay informed and use the right products, improving overall health outcomes.
Lower Costs and Greater Efficiency: Better communication leads to fewer missed appointments, more efficient processes and greater patient participation in their healthcare journeys.
Greater Satisfaction: Patients and customers appreciate having a choice in how they communicate with their providers and healthcare suppliers, leading to higher satisfaction, loyalty and trust.
Reduce Missed Appointments: Instant notifications and reminders via text can help patients stay on top of their appointments and follow-ups.

Secure Texting is Key to Modern Healthcare Communication

Patient portals alone are no longer enough to drive the kind of patient engagement needed for optimal healthcare outcomes. By integrating secure texting apps for healthcare with other communication tools like email and web forms, providers can offer a more patient-centric approach to healthcare communication.

At LuxSci, we’re committed to helping healthcare providers offer secure, HIPAA-compliant communication solutions that improve patient engagement, outcomes and results. By giving patients the flexibility to choose their preferred communication channel—whether it’s secure texting, email, phone, or a patient portal—you can increase engagement, improve outcomes, and lower costs.

HIPAA compliant hosting requirements include administrative policies for workforce training and access management, physical controls for data center security and equipment protection, and information protections for data encryption, access controls, and audit logging. Healthcare organizations using hosting services must ensure providers implement appropriate business associate agreements, security measures, and compliance documentation that meet Privacy and Security Rule obligations for protecting electronic PHI. Healthcare organizations increasingly rely on cloud hosting and managed services to support their operations while reducing internal IT infrastructure costs. Outsourcing hosting responsibilities does not eliminate HIPAA compliant hosting requirements, requiring careful vendor selection and ongoing oversight.

Administrative Protection Standards

Workforce training requirements mandate that hosting providers educate their personnel about HIPAA obligations and PHI handling procedures. All staff with potential access to healthcare client data must understand privacy requirements and security protocols before gaining system access. Access management procedures ensure that hosting provider personnel receive appropriate permissions based on their job responsibilities and healthcare client needs. Role-based access controls limit employee exposure to PHI while enabling necessary system administration and support activities. Security officer designation requires hosting providers to appoint qualified individuals responsible for developing and implementing security policies that protect healthcare client data. Officers must have appropriate authority and expertise to ensure comprehensive compliance across hosting operations.

Infrastructure & HIPAA Compliant Hosting Requirements

Data center security controls must protect servers and network equipment from unauthorized physical access through multiple layers of security including perimeter controls, biometric access systems, and surveillance monitoring. These protections help prevent unauthorized individuals from accessing systems containing PHI. Equipment disposal procedures ensure that storage devices and servers containing healthcare client data receive appropriate destruction when they reach end of life. Hosting providers must implement certified data destruction methods that prevent PHI recovery from disposed equipment. Environmental protections including fire suppression, climate control, and power management help ensure that healthcare client data remains available and protected from physical threats. Systems of this nature support business continuity while maintaining data integrity and accessibility.

Control Measures for HIPAA Compliant Hosting Requirements

User authentication systems verify the identity of individuals accessing hosting infrastructure before granting permissions to view or modify healthcare client data. Multi-factor authentication provides additional security layers for privileged access to systems containing PHI. Unique user identification ensures that hosting provider activities can be traced to specific individuals through comprehensive account management and monitoring systems. These controls support accountability and enable investigation of potential security incidents involving healthcare client data. Emergency access procedures provide alternative authentication methods when normal access controls might delay urgent system maintenance or security response activities. These procedures must include enhanced monitoring and documentation requirements to maintain security while enabling necessary operations.

Audit Controls and Activity Monitoring

Comprehensive logging systems capture detailed records of all activities affecting healthcare client data including user access, system modifications, and data transfers. These logs must be protected from unauthorized modification and preserved for appropriate periods to support compliance demonstrations. Regular log analysis helps hosting providers identify unusual activity patterns that might indicate security threats or compliance violations. Automated monitoring tools can detect suspicious behavior and alert security personnel to potential incidents requiring investigation. Audit trail preservation ensures that activity records remain available for compliance reviews and incident investigations throughout required retention periods. Hosting providers must maintain secure log storage while providing healthcare clients with access to relevant audit information.

Data Integrity and Transmission Security

Encryption implementation protects healthcare client data during storage and transmission through approved cryptographic methods and key management practices. Hosting providers must maintain current encryption standards while ensuring that decryption capabilities remain available for legitimate access needs. Data validation procedures verify that healthcare client information maintains accuracy and completeness throughout processing and storage activities. These procedures help detect unauthorized modifications or corruption that could compromise data integrity or patient care. Backup and recovery systems maintain additional copies of healthcare client data while preserving security protections and access controls. Frequent testing ensures that backup systems function properly and can restore data without compromising compliance requirements.

Network Security and Communication Controls

Firewall configuration creates secure network boundaries that control traffic between healthcare client systems and external networks. These controls help prevent unauthorized access while enabling necessary communication for healthcare operations and patient care. Intrusion detection systems monitor network traffic for potential security threats and unauthorized access attempts involving healthcare client data. Automated alerting helps hosting providers respond quickly to potential incidents while maintaining comprehensive security coverage. Secure communication channels protect data transmission between healthcare clients and hosting infrastructure through encrypted connections and authenticated access methods. These channels help ensure that PHI remains protected during transfer and remote access activities.

Business Associate Agreement Obligations

Contractual requirements establish hosting provider responsibilities for PHI protection including specific security measures, incident response procedures, and compliance monitoring activities. These agreements must address all applicable HIPAA compliant hosting requirements while defining clear performance expectations. Liability allocation between healthcare organizations and hosting providers depends on their respective roles in PHI protection and which party controls different aspects of data security. Clear contractual provisions help define responsibility for various compliance obligations and potential violations. Termination procedures address how healthcare client data is handled when hosting relationships end including data return, destruction, or transfer requirements.

Compliance Monitoring and Vendor Oversight

Risk assessment procedures help healthcare organizations evaluate hosting provider security practices and identify potential vulnerabilities that could compromise PHI protection. These assessments should be conducted regularly and documented to demonstrate due diligence in vendor oversight. Performance monitoring tracks hosting provider compliance with contractual obligations and HIPAA requirements through security audits, incident reviews, and service level assessments. Healthcare organizations must maintain ongoing oversight rather than relying solely on initial vendor evaluations. Documentation requirements ensure that hosting providers maintain records demonstrating their compliance efforts including policies, training materials, audit results, and incident reports. Well kept records support healthcare client compliance demonstrations and regulatory reviews when requested.

How To Overcome Email Encryption Challenges in Healthcare

April 14, 2025
Pete Wermter

Encryption is a critical security measure for protecting electronic protected health information (ePHI) included within email communications, and a key technical safeguard under the HIPAA Security Rule. However, despite its efficacy in helping protect sensitive patient data from malicious actors, encryption can be difficult to successfully implement.

Technical complexity, user resistance, and compatibility issues across different email systems can emerge as persistent problems, leading to frustration, risky workarounds, and, ultimately, increased risk of ePHI exposure and compliance violations. Without thoughtful deployment and support, encryption can become a barrier to successful secure email communication in healthcare, as opposed to a measure that underpins it.

To help you ensure secure, HIPAA compliant email communication, this post discusses the main encryption challenges you’re likely to encounter, how they can diminish your email security posture, and the measures you can take to overcome them.

What Is Email Encryption?

Before we discuss the most frequent email encryption challenges faced by healthcare organizations, here’s a quick refresher on what email encryption is and why it’s so important for securing sensitive patient data.

Email encryption is the process of scrambling the content of a message to make it unreadable as it’s sent to recipients or stored in a database. Only the intended recipient, who has the encryption key, can decrypt the email and access the data within.

Consequently, in the event an encrypted message is intercepted by malicious actors in transit or exfiltrated from a data store during a security breach, they won’t be able to make sense of it. This renders any ePHI included in the message unintelligible and, therefore, worthless, adding another layer of security that preserves patient privacy – and keeps your business safe.

Common Email Encryption Challenges

Let’s move on to detailing some of the most frequent encryption challenges that must be overcome by healthcare organizations to ensure secure email communication and HIPAA compliance.

Decrypting Messages Is Too Difficult

The more difficult or drawn out it is for recipients to decrypt their email messages, the more likely they’ll simply go unread or end up deleted. If the decryption process is too cumbersome, which could include requiring a user to log into a separate site (i.e., a web portal), verify their identity multiple times, create a new account, or install additional software, it adds complexity. This can drive users to seek workarounds or cut corners, such as having information sent to them through unsecured channels, which puts your company at risk.

Similarly, email clients, browsers, and security settings may impact the decryption process, causing compatibility issues that prevent users from accessing their messages. Within a healthcare setting, where timely communication is crucial, such obstacles can disrupt workflows, slow down patient care, and lead to HIPAA compliance violations if users resort to unencrypted alternatives.

Encryption that Requires Manual Intervention

Some email encryption tools require users to manually encrypt messages. If users forget to apply encryption or misconfigure settings, sensitive patient data could be exposed, leading to compliance violations and ePHI exfiltration.

For employees who handle ePHI and need to send encrypted emails, remembering to enable encryption (vs. automated encryption) is an extra step that introduces the risk of human error into the process. To offer a related, and more relatable, example: how many times have you forgotten to include an attachment when sending an email, even when referencing the attachment in the message? It’s all too easily done. In the same way, an inexperienced, tired, or distracted user could simply neglect to turn on or correctly configure encryption before sending an email, putting patient data at risk.

Increased IT and Administrative Overhead

The two email encryption challenges outlined above contribute to a third overarching difficulty for healthcare organizations: an increased workload for its IT, security and operations teams.

First of all, IT, security and operations must establish and continuously enforce encryption policies, configuring rules that ensure sensitive patient data is encrypted while non-sensitive, business communication continues to flow unobstructed. Misconfigured policies can cause over-encryption, resulting in user inaccessibility and disruptions, or under-encryption, leading to exposure of ePHI and HIPAA compliance violations.

Second, IT support teams must troubleshoot user issues: namely employees and external recipients who are unfamiliar with encryption protocols and need support in overcoming difficulties in message decryption. These could be caused by compatibility issues between different email clients or systems, expired or missing digital certificates, incorrect key exchanges, or confusion surrounding accessing encrypted messages through portals or attachments.

Lastly, IT and governance teams must keep up-to-date with changing regulatory updates and email security threats. As compliance requirements evolve, healthcare organizations must reassess encryption standards, upgrade outdated protocols, and ensure that their workforce adheres to best practices. Without an adequate strategy and the right systems in place, managing encryption can become a constant drain on IT bandwidth, taking personnel away from other aspects of their work that contribute to patient care.

Effective Strategies For Email Encryption

Having discussed the most common encryption challenges and how they can impact a company’s email security posture, let’s look at some of the most powerful mitigation strategies, which will improve the email encryption experience for both senders and recipients.

Balance Security With Ease of Use

To overcome the challenges of user inaccessibility, human error, and excessive administrative overhead, healthcare organizations must balance the ease of use of their encryption solutions with the level of security they provide.

While opting for the most secure encryption protocols intuitively seems like the best option, extra security often comes at the expense of usability, which can render the encryption irrelevant if users decide to circumvent it altogether, as outlined earlier. Instead, it’s essential to evaluate the sensitivity of message content and select a corresponding level of encryption.

Moving onto practical technical examples, Transport Layer Security (TLS) is a widely used email encryption standard, thanks to its ease of implementation and use, i.e., once activated, no further action is required by the user to encrypt the message content. However, TLS only encrypts ePHI in transit, i.e., when being sent to recipients, which may prove insufficient for highly sensitive patient data.

In contrast, encryption protocols such as Secure/Multipurpose Internet Mail Extensions (S/MIME), AES-256 and Pretty Good Privacy (PGP) provide more comprehensive encryption, safeguarding the ePHI contained in email communications both in transit and at rest, i.e., when stored in a database. Now, while this makes them more effective at securing patient data and achieving HIPAA compliance, these standards are more complicated to implement and to use than TLS encryption.

S/MIME requires users to obtain and install digital certificates from a Certificate Authority (CA), which verifies their respective identities and provides the public key for encryption. Consequently, both the sender and recipient must have valid certificates; if either party’s certificate is revoked or expires, they won’t be able to encrypt or decrypt the message, respectively.

With PGP, meanwhile, users must manually generate and exchange public/private keys. This offers greater flexibility than S/MIME but requires careful key management, which can be confusing for non-technical users. If a recipient doesn’t have the sender’s public key, they won’t be able to decrypt the message. Additionally, both S/MIME and PGP require a public key infrastructure (PKI), which can add considerable administrative overhead, particularly in regards to the management of certificates, public keys, and user credentials.

Accounting for this, healthcare organizations can balance security with accessibility by employing a tiered encryption strategy: using TLS for lower-risk communication while opting for S/MIME or PGP for more sensitive communications.

Enable Automatic Encryption

Subsequently, the challenge of balancing security with accessibility can be remediated by deploying an email delivery platform that not only removes the need for manual user intervention but also automatically applies the appropriate encryption standard based on message content and delivery conditions. Rather than relying on users to choose the correct method—or worse, bypass encryption altogether—modern email solutions like LuxSci can intelligently enforce encryption without affecting the user experience.

Many healthcare companies rely on TLS encryption because it eliminates the need for encryption keys or certificates, additional log-ins, etc. For this reason, it’s often referred to as ‘invisible encryption’ for its lack of effect on the user experience.

However, to be most effective, both the sender’s and recipient’s email servers must support enforced TLS (i.e., TLS 1.2 and above). In the event the recipient’s email server doesn’t support TLS, the email message will be delivered unencrypted or fail to send altogether, depending on the server configurations. Additionally, once the email is delivered to the recipient’s inbox, unless the recipient’s email infrastructure encrypts messages at rest, it will be stored in an unencrypted format.

Consequently, while TLS is ideal for email messaging that doesn’t contain highly sensitive ePHI, it’s insufficient for all healthcare communication. To ensure the secure and HIPAA compliant inclusion of patient data in emails, healthcare organizations should opt for an email solution that supports automated, policy-based encryption, which can upgrade to S/MIME or PGP when necessary. This offers the combined benefits of optimal ePHI security, minimal administrative burden, and removing the need for staff intervention.

Invest in Employee Education

While a flexible encryption policy and deploying email solutions that support automation will go a long way towards overcoming email encryption challenges, these efforts can still be undermined if users aren’t sufficiently educated on their benefits and use. For this reason, it’s crucial that healthcare companies take the time to educate their employees on both the how and why of email encryption.

Even the most advanced encryption systems can fail if employees don’t understand how to use them properly, as well as what to look out for in their day-to-day email use. Some aspects of email encryption, such as recognizing secure message formats or troubleshooting delivery issues, may still require user awareness. With this in mind, employee training programs should focus on recognizing when additional encryption measures are necessary, how to ask for assistance, the dangers of unsecured channels, and how to report suspicious activity in addition to the practical aspects of using your email delivery platform.

How to make Gmail HIPAA Compliant?

November 1, 2024
LuxSci

Gmail is not HIPAA compliant by default, but can become HIPAA compliant when properly configured within Google Workspace (formerly G Suite) with a Business Associate Agreement and additional security measures. Standard Gmail accounts lack the encryption, access controls, audit capabilities, and contractual protections required for handling protected health information. Healthcare organizations must implement proper security enhancements and policies to achieve Gmail HIPAA compliant status for email communications containing patient information.

Gmail HIPAA Compliant Security Limitations

The standard version of Gmail lacks several elements needed for HIPAA compliant email communications. While Gmail provides basic Transport Layer Security (TLS) encryption during transmission, this protection only works when the recipient’s email server also supports TLS. Free Gmail accounts cannot be covered by a Business Associate Agreement (BAA), which HIPAA regulations require for any third-party handling protected health information. Access control options in standard Gmail don’t provide the detailed permission settings and audit trails needed for healthcare environments. These limitations mean that using regular Gmail for patient communications puts healthcare organizations at risk of compliance violations and potential penalties.

Requirements for Gmail HIPAA Compliant Usage

Making Gmail HIPAA compliant requires several important steps and enhancements. Organizations must upgrade to Google Workspace (formerly G Suite) to access enterprise-level security features unavailable in free accounts. A Business Associate Agreement must be executed with Google, establishing their responsibilities for protecting healthcare information. Additional security layers like end-to-end encryption need implementation since Google’s BAA doesn’t make Gmail automatically HIPAA approved for all email communications. Staff training programs must cover proper handling of protected health information in emails, including avoiding sensitive information in subject lines. These combined measures create the foundation for using Gmail in HIPAA compliant healthcare communications.

Enhanced Security Configurations

Google Workspace includes security features that support HIPAA compliant email practices when properly configured. Advanced security settings allow administrators to enforce two-factor authentication for all users accessing healthcare information. Data loss prevention rules can identify and protect messages containing patient information patterns. Vault retention capabilities maintain email records according to healthcare requirements. Access controls restrict which staff members can view, send, or manage emails containing protected information. While these built-in features improve security, they often require additional enhancements to meet all HIPAA requirements for email communications containing patient information.

Email Gateway Solutions for Complete Compliance

Many healthcare organizations implement secure email gateways to bridge the compliance gap between Google Workspace and full HIPAA approved email status. These gateway solutions integrate with Gmail to provide stronger encryption that protects messages both in transit and at rest, regardless of recipient email systems. Automatic message scanning identifies and encrypts emails containing protected health information without requiring staff intervention. Detailed audit trails document who accessed what information and when these actions occurred. Gateway solutions help organizations maintain HIPAA compliant email practices while still benefiting from Gmail’s familiar interface and integration capabilities.

Staff Training and Policy Requirements

Technology alone cannot guarantee HIPAA compliant Gmail usage without proper human behavior guidelines. Organizations must establish clear policies about what patient information may be included in emails and how different types of messages should be secured. Staff training needs to cover recognizing protected health information and understanding when encryption must be used. Visual indicators help users identify when they’re composing secure versus standard emails. Regular refresher training addresses emerging threats and changing regulations affecting healthcare communications. Healthcare organizations must document that staff have completed training and understand email security policies to demonstrate compliance efforts.

Maintaining Ongoing Email Compliance

HIPAA compliant email practices require continuous monitoring and periodic reassessment. Regular security reviews verify that Gmail configurations and additional security measures remain effective as technologies and threats evolve. Audit log reviews help identify unusual patterns that might indicate security issues or policy violations. Compliance documentation needs updating as Google makes changes to workspace features or terms. Periodic testing ensures encryption and security measures function properly across all devices used for email access. These ongoing management practices help healthcare organizations maintain HIPAA approved email communications while leveraging Gmail’s productivity benefits.

Alternatives to Gmail for Healthcare Communications

Some healthcare organizations determine that alternatives to Gmail better meet their HIPAA compliant email needs. Specialized healthcare communication platforms include features designed specifically for medical environments and patient interactions. Email services with HIPAA compliance built into their core design may reduce the need for additional security layers and configurations. Patient portal messaging systems provide more controlled environments for healthcare communications than email. These alternatives may prove more cost-effective for organizations handling large volumes of protected health information, though they lack Gmail’s widespread adoption and familiarity. The right choice depends on each organization’s communication needs, technical capabilities, and compliance resources.
