Are Replies to Encrypted Emails also Secure?

Business Solutions, HIPAA Compliant Email

December 26, 2023

Sending HIPAA-compliant emails is easy when you use an encryption solution like LuxSci. But what happens when someone replies to an encrypted message? Are the replies also secure? This is primarily a concern when using SMTP TLS as a secure means of email delivery.

This article will explain how messages are sent securely, how replies behave, and whether they are secure and compliant. At the end, we provide some recommendations for how to balance security and usability.

How are HIPAA-compliant Secure Emails Sent?

In general, there are four ways to securely send HIPAA-compliant email messages to a recipient. The way the original message is encrypted will determine the nature of how secure the reply is.

PGP and S/MIME Encryption

LuxSci supports these highly secure email encryption methods for those who wish to use them. However, as they require more setup and coordination with your recipients, most HIPAA-compliant accounts use something other than PGP and S/MIME for business email communications.

To send messages using PGP and S/MIME encryption, you must exchange certificates with the recipient and install them in the mail client to encrypt and decrypt messages. Some organizations will use this technology for internal communications because they can manage the setup. However, this method is impractical for securing large-scale external communications. When most people talk about encrypted email messages, they refer to one of the methods: secure web portal or SMTP TLS encryption.

Secure Web Portal Encryption

Messages that utilize the secure web portal method of encryption are secured, stored, and accessed via a secure database. It works like this. The sender’s message is sent to a secure web portal, and a simple notification message (that does not contain PHI) is sent to the recipient. The recipient clicks on a link in this notice, verifies their identity by logging in, and then can access the message within the portal.

This is very secure and works with any recipient’s email address. However, accessing the message requires extra work on the recipient’s part. They must log into the portal to read the secure message.

SMTP TLS Encryption

Messages encrypted with SMTP TLS appear like any other email in the recipient’s inbox. They are only encrypted as they are transmitted from the sender’s servers to the recipient’s servers. Unless the recipient knows where to look in the metadata, they may not know TLS-encrypted messages are secured at all.

Unlike secure web portal encryption, which can send encrypted messages to any active email address, SMTP TLS can only be used to secure messages if the recipient’s email service supports the technology. Today, the majority of email providers support TLS. However, some older email service providers do not. If the recipient’s servers do not support TLS, you cannot send them encrypted messages using this technology.

Are Replies to Encrypted Emails Also Encrypted?

That brings us back to our original question: are replies to encrypted emails also secured? The answer will depend on what type of encryption was initially used. When your recipient replies to your HIPAA-compliant secure email message, here is what could happen:

PGP and S/MIME Replies

We won’t spend much time discussing PGP and S/MIME, but we will answer the question. Replies to email messages secured with PGP and S/MIME encryption will also be encrypted, assuming all certificates are correctly configured.

Secure Web Portal Replies

Most secure web portals offer an option for the recipient to reply directly within the portal. If the recipient replies in the portal, the message is automatically secured with the same high level of encryption it was sent with.

However, we can’t assume that the recipient will use the portal to reply. Some people could use their email program to reply to the notification message instead of using the portal. In that case, the reply may or may not be secure, depending upon whether their email system supports TLS or other email security measures. It’s best to assume these replies to the notification message will be insecure.

Replies to SMTP TLS Messages

When a recipient replies to an email sent using SMTP TLS, they use their regular email system to send that message. This may or may not be secure, depending on whether their email system supports TLS or other email security measures. For HIPAA compliance reasons, you should assume that the message will be sent insecurely.

If the Reply to an Encrypted Message is Insecure, Is the Email Non-Compliant?

That leads us to an interesting follow-up question- if replies to encrypted messages are not secure, does this mean the system is non-compliant?

The short answer is: No.

Why? HIPAA only applies to covered entities and their business associates. To comply with HIPAA regulations, these organizations must properly secure any PHI transmitted or stored in their systems. Patients are not subject to HIPAA regulations.

The patient can choose to send their information insecurely or use alternate channels like a phone call or in-person appointment to communicate their health information if concerned about the security of their account. When a patient replies to a message from their healthcare provider, they are transmitting their own information and do not have to do so securely.

Should SMTP TLS be Used to Send HIPAA-Compliant Secure Emails?

HIPAA is notoriously technology-neutral. It tells you what to do but not how to do it. As a result, what is minimally required and what is best are sometimes very different things. Because of that, customers have a wide range of expectations for how they would like things to work.

At LuxSci, HIPAA-compliant email accounts have SMTP TLS enabled automatically, so every message is sent with a base level of encryption. This is for maximum usability. Customers can turn off SMTP TLS as the sole method of secure email delivery or use it only for selected recipients (like their co-workers). It is up to the customer to choose which encryption methods they think are best for their organization. At a minimum, using TLS is better than using no encryption, but each organization will have different requirements and risk factors.

There are no compliance reasons why SMTP TLS should not be used. Still, organizations may want to reduce their risk by increasing the level of encryption when sending communications that contain PHI to patients.

Recommended Best Practices For Sending HIPAA-Compliant Secure Emails

The best practices for security are often at odds with the best user experience. This is often true in security and HIPAA compliance. Finding the right balance of security and usability is essential to protect patient data and meet business objectives. Utilizing TLS for some emails and secure web portal encryption for others is likely the best solution. When spreading awareness and engaging patients with low-sensitivity messages like appointment and vaccine reminders is the goal, using TLS (with some fallback or exclusion to avoid sending insecurely) is likely the right idea. When sending highly sensitive information like lab results, medical records, or billing statements, using a more secure form of encryption, like a secure web portal, is wise to reduce the risk of inappropriate disclosures.

Traditional MFA No Longer Qualifies as “Reasonable” Security

March 17, 2026
Pete Wermter

For years, multi-factor authentication (MFA) was considered one of the most effective ways to protect sensitive systems. By requiring a second verification step, such as a text message code or push notification, organizations could significantly reduce the risk of compromised passwords.

But the threat landscape has changed.

Today, attackers routinely bypass traditional MFA using techniques such as MFA evasion, token replay attacks, and consent phishing. These methods are no longer rare or highly sophisticated. They are widely used, automated, and increasingly effective.

As a result, regulators, auditors, and security frameworks are raising expectations for authentication security. For healthcare organizations in particular, traditional MFA alone may no longer satisfy the HIPAA requirement to implement “reasonable and appropriate safeguards.”

In the near future, email systems that rely only on basic MFA, without conditional access or phishing-resistant authentication, may increasingly be viewed as security gaps during risk assessments.

Why Traditional MFA Is No Longer Enough

Traditional MFA still improves security compared to passwords alone. However, many common MFA methods were designed before today’s phishing techniques and cloud authentication attacks became widespread.

Common MFA methods include:

SMS verification codes
Email-based authentication codes
Push notifications to mobile apps

While these mechanisms add friction for attackers, they can still be intercepted or manipulated during sophisticated phishing attacks. Because modern attackers now target authentication workflows directly, organizations relying solely on traditional MFA may be more vulnerable than they realize.

How Attackers Bypass MFA Today

Cybercriminals increasingly rely on tools that capture credentials and authentication tokens during login sessions. Three attack techniques are now especially common.

MFA Evasion and Phishing Proxies – Attackers frequently deploy adversary-in-the-middle phishing kits that sit between the user and the real login service. When users enter their credentials and MFA code on a phishing page, the attacker forwards the information to the legitimate site and captures the authentication session. The user successfully logs in—but the attacker gains access as well. If attackers capture those tokens, they can reuse them to access the account directly.
Token Replay Attacks – After successful authentication, systems typically issue session tokens that allow users to remain logged in without repeated MFA prompts. This technique has been widely observed in attacks targeting cloud email platforms such as Microsoft 365, allowing attackers to access email data even when MFA is enabled.
Consent Phishing – Consent phishing bypasses MFA entirely. Instead of stealing passwords, attackers trick users into granting permissions to malicious applications that request access to their mailbox or files. If users approve the request, the attacker’s application receives persistent access to the account through APIs—often without triggering security alerts.

Why Email Authentication Matters Most in Healthcare

Email remains one of the most critical systems in healthcare organizations. It supports patient communication, internal collaboration, and the exchange of sensitive information. Unfortunately, it is also the most frequently targeted entry point for cyberattacks.

Once attackers gain access to an email account, they can:

Impersonate healthcare staff
Launch internal phishing attacks
Access sensitive patient communications
Extract protected health information (PHI)

Because of this, email authentication controls are becoming a major focus for security teams and compliance auditors alike.

Evolving Regulatory Expectations

HIPAA does not prescribe specific technologies, but it requires organizations to implement safeguards that are “reasonable and appropriate” based on risk. As new attack methods emerge, the definition of reasonable security evolves.

Today, many security frameworks and regulatory bodies are emphasizing stronger identity protections, including:

Phishing-resistant authentication
Conditional access policies
Monitoring for suspicious login behavior
Controls for third-party application permissions

Organizations that rely solely on basic MFA may increasingly struggle to demonstrate that their authentication protections are sufficient.

The Shift Toward Phishing-Resistant Authentication

To address the weaknesses of traditional MFA, many organizations are adopting phishing-resistant authentication technologies, which can be enabled with tools like Duo and Okta. These solutions rely on cryptographic authentication tied to trusted devices, which prevents attackers from capturing or replaying login credentials.

Examples include:

Hardware security keys
Passkeys
Certificate-based authentication

Because authentication is tied to both the device and the legitimate website domain, these technologies significantly reduce the success rate of phishing attacks.

Why Conditional Access Is Becoming Essential

Conditional access adds another layer of protection by evaluating context and risk before granting access. Instead of treating every login the same, conditional access policies analyze signals such as:

Device security status
Geographic location
Network reputation
User behavior patterns

If something appears unusual, such as a login from a new country, the system can require stronger authentication or block the attempt altogether. This risk-based approach to authentication helps prevent many account compromise scenarios.

The Future of HIPAA Risk Assessments

As authentication threats evolve, healthcare security assessments are increasingly focusing on identity protection maturity. Organizations may begin seeing findings related to:

Weak or outdated MFA methods
Lack of conditional access policies
Insufficient monitoring of login activity
Unrestricted third-party application permissions

In particular, email systems without advanced authentication protections may be flagged as high-risk vulnerabilities, especially when PHI is accessible.

LuxSci’s Modern Approach to MFA

Modern threats require more than a simple second login factor. LuxSci approaches authentication security with layered identity protection designed specifically for healthcare environments.

Instead of relying solely on basic MFA methods like SMS codes or email verification, LuxSci supports stronger authentication controls and policies that align with evolving security expectations. These protections can include:

Strong multi-factor authentication options
Monitoring for unusual login behavior
Enhanced identity verification mechanisms

By combining multiple security layers within its HIPAA-compliant secure communications email and marketing solutions, LuxSci helps healthcare organizations protect sensitive email communications while maintaining usability for providers, health plan administrators, payment providers, and patient engagement teams.

Conclusion

Multi-factor authentication remains an important security control—but not all MFA is created equal. Attack techniques such as phishing proxies, token replay, and consent phishing have demonstrated that traditional MFA methods can be bypassed. As a result, regulators and auditors are increasingly expecting stronger identity protections.

For healthcare organizations that rely heavily on email communications, the implications are significant. Weak authentication controls can expose sensitive patient data and may soon appear as high-risk findings during HIPAA risk assessments. The organizations best positioned for the future will be those that modernize authentication strategies now, moving toward phishing-resistant methods, conditional access policies, and layered identity protection.

Reach out to LuxSci today to learn how HIPAA compliant email can support both your organization’s engagement and cybersecurity needs.

Encryption Optional Email Will Fail Audits in 2026 and Beyond

February 24, 2026
Pete Wermter

For years, healthcare organizations have relied on click-to-encrypt email workflows and secure portals as a practical compromise between usability and compliance. Or in some cases, they simply thought most of their emails did not need to be compliant. In regulated industries where data security and privacy are paramount, this approach was still considered “good enough.”

That era is ending.

As we progress into 2026 and beyond, regulators, auditors, and cyber insurers are sending a clear and consistent message: encryption that depends on human choice is no longer acceptable. It’s already happening. Encryption optional email isn’t merely raising concerns, it’s failing audits outright.

An Email Threat Landscape That’s Changing Faster Than Email Habits

Historically, email encryption was treated as a best practice rather than a hard requirement. If an organization could demonstrate that encryption tools existed and that employees had access to them, auditors were often satisfied. The box was checked, everybody moved on.

Today, the questions auditors ask are fundamentally different. Instead of asking whether encryption is available, they are asking whether sensitive data can ever leave the organization unencrypted. If the answer is yes, even in rare cases, or even accidentally, that’s no longer viewed as an acceptable gap. It’s viewed as inadequate control.

Why 2026 Is a Tipping Point for Email Security

Several forces are converging here in 2026 that make optional encryption increasingly untenable. Regulatory scrutiny around PHI and PII exposure continues to intensify. Breach costs and litigation are rising, with email remaining one of the most common vectors for data exposure and breaches. AI is also changing the game for cybercriminals, and attacks will continue to increase and be more sophisticated. As a result, cyber insurers are tightening underwriting requirements and demanding stronger, more predictable controls.

At the same time, email user behavior is unpredictable and inconsistent, which is a non-starter for data security in today’s world.

Taken together, these trends and behaviors point to a single requirement: email security controls must be automated. They must be enforced by systems, not dependent on employee memory, judgment, or good intentions.

The Reality of “Encryption Optional” in Practice

On paper, optional encryption can sound reasonable. In practice, it creates gaps large enough to open you up to a breach.

Secure portals are a good example. They require recipients to click a link, authenticate, and access content in a controlled environment. While this protects data in transit, and is a better approach than no security at all, it also introduces friction. And people don’t like friction. Senders forget to use the portal. Recipients ask for “just a quick email instead.” Shortcuts are taken to save time. And every shortcut becomes a risk.

Click-to-encrypt systems suffer from a similar problem. They rely on users to correctly identify sensitive data and remember to take action. But people often misclassify information, forget to click the button, or assume someone else has already secured the message. From an auditor’s perspective, this isn’t a training failure. It’s a set-up and control failure.

Email Security Defaults Are the New Normal

The latest message from regulators, auditors, and insurers is clear. If encryption is optional, data vulnerabilities become inevitable.

What can you do?

Below is a quick email security checklist to help you get started. Cyber insurers may require or recommend the following safeguards during the underwriting process, such as:

Multi-factor authentication (MFA)
Endpoint protection
Encrypted backups
Incident response planning
Encryption protocols for sensitive data in transit and at rest, including PHI in emails

In 2026 and beyond, healthcare organizations and regulated industries will be judged not by what they allow, but by what they prevent. Automated, encrypted email is the new. normal.

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.

What is the Cheapest HIPAA Compliant Email?

November 11, 2024
Pete Wermter

The cheapest HIPAA compliant email options include budget-friendly plans from Paubox, Virtru, and Google Workspace when properly configured with security add-ons. Healthcare organizations should consider total costs including implementation, training, and ongoing management expenses. While consumer email services cost less, they lack the security features and Business Associate Agreements necessary for HIPAA compliant email communications with patients.

Entry-Level HIPAA Compliant Email Services

Several providers offer affordable HIPAA compliant email options for smaller healthcare practices and organizations with limited budgets. LuxSci and Paubox provide encrypted HIPAA compliant email with a Business Associate Agreement included, including support for securing Google Workspace and Microsoft 365. Virtru also offers email encryption for small teams. ProtonMail Professional includes encryption, though healthcare organizations must verify BAA availability. Google Workspace and Microsoft 365 Business provide foundational platforms, but require additional security configurations and add-ons to achieve full HIPAA compliance. These baseline services provide encryption and security features while keeping monthly costs manageable for smaller healthcare entities.

Non Subscription Fee Budget Considerations

The true cost of HIPAA compliant email extends beyond monthly subscription prices. Implementation expenses include configuration time, security testing, and integration with existing systems. Staff training introduces both direct costs and productivity impacts during the learning period. Ongoing management requires dedicated IT resources or outsourced support services. Audit preparations and compliance documentation demand administrative attention. Organizations also face potential costs from security incidents if they choose inadequately protected budget options to save money. Many healthcare providers discover that selecting email services based solely on subscription prices leads to higher overall expenses. A thorough cost analysis should include all implementation and operational factors rather than focusing exclusively on monthly fees, and also should consider the vendor’s customer support practices and reputation.

Security Features and Compliance Trade-offs

Less expensive HIPAA compliant email services may offer fewer security features than premium alternatives. Basic plans typically provide essential encryption during transmission but might lack advanced access controls or comprehensive audit logging. Less costly options often exclude data loss prevention tools that automatically detect and secure messages containing patient information. Mobile device security features may be limited in budget-friendly plans. Archive and retention capabilities might require additional paid add-ons. Password management and multi-factor authentication options vary considerably between providers. Healthcare organizations must carefully evaluate whether security limitations in less expensive services align with their risk management requirements. Finding the right balance between cost and protection depends on each organization’s specific patient communication needs.

Provider Reliability and Support Quality

Lower-priced HIPAA compliant email providers differ substantially in reliability and customer support quality. Some lower cost services experience more frequent outages or performance issues than premium alternatives. Customer support availability ranges from 24/7 assistance to limited business hours only. Support channels vary from direct phone access to email-only communications. Implementation assistance might be comprehensive or nearly non-existent depending on the provider. Security update frequency and speed of vulnerability patching also differs between services. Healthcare organizations should investigate reliability statistics and read customer reviews about support experiences before selecting a provider. The operational impact of service disruptions or delayed support responses can quickly outweigh small differences in monthly subscription costs.

Cost-Effective HIPAA Compliant Email Implementation

Healthcare organizations can reduce HIPAA compliant email expenses through strategic implementation approaches. Tiered and role-based access limits higher-cost security features to staff who routinely handle protected health information while providing basic service to other employees. Negotiating multi-year contracts often yields substantial discounts compared to month-to-month arrangements. Starting with pilot projects allows testing services before full organizational commitment. Exploring whether existing IT infrastructure can support secure email reduces the need for completely new systems. Selecting services that integrate with existing systems minimizes implementation costs and training requirements. These practical approaches help organizations achieve HIPAA compliance while controlling email expenses.

Long-Term Value Assessment

Evaluating HIPAA compliant email options requires looking beyond initial price tags to assess long-term value. Less expensive services may lack scalability for organizational growth, necessitating costly migrations later. Budget options sometimes require more staff time for management and security monitoring, creating hidden operational costs. Cheaper services might provide fewer automation features that could otherwise reduce administrative burdens. Integration capabilities with electronic health records and practice management systems vary considerably between providers. Forward-looking healthcare organizations consider how email solutions will adapt to changing regulations and emerging security threats. While immediate budget constraints matter, the most cost-effective HIPAA compliant email solution often depends on an organization’s growth trajectory and long-term communication strategy.

With email communication playing a critical role in the customer engagement strategies of virtually every organization, high email deliverability rates are vital to success across all industries. In the healthcare sector, however, the stakes can be far higher. An undelivered email isn’t merely an inconvenience or a lost sales opportunity; it could mean a missed appointment, a delay in a prescription refill, or a failure to get a patient critical healthcare information. Or worse, the email could end up in the hands of an unintended recipient, including bad actors and cybercriminals.

With this in mind, this post details why high email deliverability is essential for healthcare companies, as well as how your organization benefits from reliable and rapid email delivery.

Speed and Efficiency

The primary reason that high email deliverability is crucially important to healthcare organizations is to best guarantee essential communications that directly impact an individual’s healthcare journey reach them promptly. These transactional emails can include appointment reminders, prescription renewals, product order confirmations, test results, explanation of benefits notices, payment reminders, and invoices. Administrative notifications related to software or systems that a patient might use, such as a password reset for an online portal, also fall under the category of transactional emails.

When transactional emails are delayed or fail to reach people altogether, they can compromise a patient’s ability to access care, adhere to treatment plans, stay informed on key facets of their healthcare journey, and, ultimately, achieve optimal health outcomes.

When a patient fails to receive an expected email, such as a prescription confirmation, for example, it can leave them feeling confused and unsure of what to do next. For individuals who are sick, elderly, or managing chronic conditions, this can cause unnecessary stress, anxiety, and even compromise adherence to care plans.

In contrast, high email delivery rates create the opposite effect, helping patients get the communications and information they need. This increases their trust in your company and gives them a firmer sense of control over their healthcare journey.

Compliance with HIPAA Regulations

While the above point stresses the importance of reliable email delivery for the patient’s and customer’s benefit, healthcare companies also have a vested interest in ensuring communications reach the intended recipient for regulatory and patient privacy reasons.

To comply with the Health Insurance Portability and Accountability Act (HIPAA), emails that contain sensitive patient data, i.e., electronic protected health information (ePHI), must be securely delivered to the intended recipient. If, on the other hand, a communication containing ePHI fails to reach the intended recipient patient, that represents a failure in secure communications and a potential HIPAA violation for your organization.

After all, where did the patient’s data go? Was it delivered to the wrong person? Was it blocked by a spam filter and is left sitting unencrypted on a server somewhere?

If you can’t answer these questions, you could be exposed to a data breach, and it could result in a HIPAA violation, meaning your organization incurrs the associated consequences, including financial penalties and reputational damage. Conversely, deploying a fully HIPAA compliant email solution, such as LuxSci, supported by a dedicated infrastructure and designed for high email delivery enables your organization to include patient data in communications with confidence and ensure you messages land in the recipient’s inbox.

Greater Levels of Personalization and Engagement

Finally, high email deliverability rates are essential for healthcare organizations because they help drive greater levels of engagement with patients and customers. Higher email deliverability means better inbox placement, leading to more emails being opened, more links being clicked, and more conversions for your communications and campaigns.

In the case of healthcare retailers, for example, this equates to converting more prospects into customers and, consequently, maximizing the ROI of email marketing campaigns, in some cases with up to 80% better results.

While healthcare marketers, understandably, focus most of their efforts on crafting attention-grabbing headlines, personalizing the message content, and the email’s design elements, these factors are rendered irrelevant if the message fails to reach the recipient in the first place! When you take this into account, high email deliverability is a crucial component in optimizing the ROI of email communications and campaigns, and an all too often overlooked component at that.

Is the Email Encrypted? How to Tell if an Email is Transmitted Using TLS

January 9, 2024
LuxSci

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);

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.
