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 Is Secure Email? The Complete Guide for Healthcare Organizations

July 29, 2026
Pete Wermter

Key Takeaways

Secure email is not the same as “email with encryption turned on.” True secure email requires enforced automated encryption, a signed BAA, access controls, audit logs, and documented processes — not just a feature toggle.
Standard email platforms like Gmail and Microsoft 365 rely on opportunistic TLS by default, which can silently fall back to unencrypted delivery if the recipient’s server doesn’t support encryption.
HIPAA’s encryption safe harbor means a misdirected but properly encrypted email is a non-event. The same email sent unencrypted is a presumed breach unless a risk assessment shows otherwise.
A signed Business Associate Agreement (BAA) with your email provider is non-negotiable — without one, you cannot legally send or store PHI through that provider.
The proposed 2025 HIPAA Security Rule update, planned for finalization in 2027, would make encryption of ePHI in transit and at rest a mandatory requirement rather than “addressable,” raising the stakes for organizations still relying on opportunistic TLS.

Best for: Healthcare IT Directors, Compliance Officers, Privacy Officers, and Marketing Managers at provider, payer, and supplier organizations that handle protected health information (PHI).

In healthcare IT, the term “secure email” gets thrown around loosely. Vendors slap the label on anything with a padlock icon, and internal teams often assume that because their provider offers TLS, they’re covered. They’re not, and the gap between what’s assumed and what’s actually required is where data breaches occur and HIPAA violations happen.

This guide breaks down exactly what secure email means from a technical and regulatory standpoint, why the email platform your staff uses every day probably isn’t compliant out of the box, and what to look for when evaluating a provider that needs to protect PHI at scale. If you want the full picture of what compliance requires beyond email specifically, our HIPAA Compliance Checklist is a useful companion read.

What Is Secure Email?

Secure email refers to an email system that protects the confidentiality, integrity, and availability of message content — specifically PHI — through a combination of technical safeguards and contractual protections. It’s not a single feature. It’s a stack of controls working together.

At minimum, secure email in a healthcare context includes:

Enforced encryption in transit, so messages can’t fall back to plaintext delivery
Encryption at rest, so stored messages remain protected on the server
Authentication protocols (SPF, DKIM, DMARC) that prevent spoofing and impersonation
Access controls and audit logs that track who accessed what, and when
A signed Business Associate Agreement (BAA) with the email provider

The distinction that trips up most organizations is this: encryption is a component of secure email, not the whole picture. A provider can offer encryption and still fail to meet HIPAA requirements if that encryption isn’t enforced, if there’s no BAA in place, or if audit logging doesn’t exist. Secure email is the combination of all these pieces functioning as a system, which is why it needs to be evaluated holistically rather than checked off feature by feature.

For healthcare provider, payer, and supplier organizations, this matters because email remains one of the highest-volume channels for PHI exposure, from clinical referrals to patient billing statements to routine staff communication. Getting the definition right is the first step toward closing the compliance gap.

Why Standard Email Is Not HIPAA-Compliant

Many healthcare organizations run on Gmail (Google Workspace) or Microsoft 365, and most assume they’re protected because encryption exists somewhere in the stack. That assumption is the single most common — and most dangerous — misconception in healthcare email security.

Here’s the problem: standard email services use opportunistic TLS by default. TLS is attempted between mail servers, but if the receiving server doesn’t support it, the message is delivered anyway — unencrypted, in plaintext. Neither the sender nor the recipient typically sees a warning. The email just goes through.

This isn’t a hypothetical edge case. IT professionals managing healthcare email infrastructure have flagged this exact issue directly: opportunistic TLS is often enabled by default and creates a false sense of security, since it offers no guarantee that a given message, including one containing PHI, won’t be transmitted in plaintext if the recipient’s mail server doesn’t support encryption. Organizations assume they’re protected simply because TLS is technically “on,” without realizing it isn’t enforced.

That gap has real consequences under HIPAA. The Security Rule currently treats transmission encryption as an “addressable” safeguard, meaning covered entities can, in theory, implement an equivalent alternative measure instead. In practice, regulators and auditors from the Office for Civil Rights (OCR) expect enforced encryption as the standard of care. “Addressable” has never meant optional — it means an organization needs a documented, defensible reason if it isn’t doing enforced encryption, and few reasons hold up under scrutiny. Finally, under OCR’s proposed changes to the HIPAA Security Rule for ePHI, scheduled for final publication in July 2027, email encryption moves from addressable to mandatory.

Beyond the encryption gap, standard consumer and even most business email plans typically lack:

A BAA that’s actually offered and signed (available on some enterprise tiers, but not automatic)
Enforced access controls beyond basic password authentication
Audit logging sufficient to meet HIPAA Security Rule requirements
Built-in encryption at rest guarantees for stored messages

None of this means Gmail or Microsoft 365 are inherently insecure products. It means their default configuration is built for general business use, not for an environment where every misrouted or intercepted message carries breach notification liability. Making either platform HIPAA-appropriate requires layering on additional tools, policies, and critically, a provider relationship that includes a signed BAA covering the exact services in use.

The Technical Components of Secure Email

Secure email is built upon five technical layers. Understanding each one, and where it fails in standard email, clarifies exactly what a compliant solution needs to deliver.

Encryption in Transit (TLS)

Transport Layer Security (TLS) encrypts the connection between mail servers as a message travels from sender to recipient. There are two flavors, and the difference between them is the crux of most healthcare email compliance failures:

Opportunistic TLS attempts an encrypted connection but falls back to unencrypted delivery if the receiving server doesn’t support it. This is the default across most consumer and business email platforms.
Enforced TLS requires an encrypted connection for delivery to succeed. If encryption can’t be established, the message fails to send rather than going out in plaintext, or a link to secure portal can be sent to securely access the information.

HIPAA’s Security Rule lists encryption as addressable, but enforced TLS has become the de facto standard that auditors and OCR expect from covered entities and business associates handling PHI over email. As one healthcare IT professional put it while debating this exact tradeoff internally: the goal is to require TLS for all outbound email and then document the remaining controls around it, treating enforced TLS as the technical baseline, with policy and process built on top.

Encryption at Rest

Transit encryption only protects a message while it’s moving. Once it lands on a mail server — sender’s outbox, recipient’s inbox, backups, archives — it needs to remain encrypted in storage. This is encryption at rest, and it’s where many organizations underestimate their exposure.

Encryption in transit alone offers zero control over a message after it’s been delivered. If the destination server isn’t itself encrypting stored data, or if a backup snapshot is taken without encryption, PHI sitting in an inbox is exposed regardless of how securely it arrived. HIPAA’s Security Rule requires safeguards for ePHI both in transit and at rest, a compliant secure email provider needs to guarantee both, not just one.

End-to-End Encryption (S/MIME, PGP)

End-to-end encryption (E2EE) encrypts message content itself, not just the connection it travels over — meaning even the email provider can’t read the content. Two standards dominate here:

S/MIME uses certificate-based encryption and is common in enterprise environments, such as healthcare, particularly where organizations already manage a public key infrastructure.
PGP (Pretty Good Privacy) uses a public/private key model and is more common in technical or security-conscious communities, though it’s less frequently deployed at scale in healthcare due to key management complexity.

E2EE isn’t a baseline requirement for every PHI-containing email, enforced TLS plus encryption at rest satisfies most use cases. But it becomes necessary for especially sensitive communications, cross-organization data sharing where you don’t control the recipient’s infrastructure, or when a business associate agreement specifically requires it.

Authentication (SPF, DKIM, DMARC)

These three protocols work together to prevent domain spoofing and email impersonation, a growing attack vector against healthcare organizations specifically, given how often phishing campaigns impersonate providers, payers, or patients.

SPF (Sender Policy Framework) specifies which mail servers are authorized to send email on behalf of a domain.
DKIM (DomainKeys Identified Mail) adds a cryptographic signature verifying a message wasn’t altered in transit.
DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do when SPF or DKIM checks fail, and provides reporting visibility.

Without these configured correctly, an organization’s domain can be spoofed to send convincing phishing emails to patients or staff, creating a security failure that compounds the compliance risk of email interception.

Digital Signatures

Digital signatures verify sender identity and confirm a message hasn’t been tampered with between sending and receipt. Paired with encryption, they close the loop on message integrity, confirming not just that content was protected, but that it came from who it claims to have come from and arrived unaltered.

Standard Email vs. Secure Email: Feature Comparison

Feature	Standard Email	Secure Email (HIPAA-Compliant)
Encryption in Transit	Opportunistic TLS — attempted but not enforced	Enforced TLS — connection fails if encryption unavailable, can include delivery via secure portal option
Encryption at Rest	Not guaranteed; provider-dependent	Required — server-side encryption of stored messages
End-to-End Encryption	Not available	Supported via S/MIME and/or PGP
Digital Signatures	Not available	Included — verifies sender identity and message integrity
Authentication (SPF / DKIM / DMARC)	Optional, rarely enforced	Required — spoofing and impersonation protection
Business Associate Agreement (BAA)	Not provided on standard plans	Required — must be signed before sending PHI
Audit Logs	Basic or none	Full audit trail — required under HIPAA Security Rule
Access Controls	Basic password only	Role-based access, MFA, admin controls
Misdirected Email	Reportable HIPAA breach	Non-reportable if properly encrypted (safe harbor)
HIPAA Compliant by Default	No	Yes

What Makes Email HIPAA-Compliant Specifically

Technical safeguards alone don’t make email HIPAA-compliant. Compliance is a combination of technology, contracts, and documented processes — all four need to be in place simultaneously. This includes:

A signed BAA with your email provider – Any vendor that transmits, processes, or stores PHI on your behalf is a business associate under HIPAA, and business associates are legally required to sign a BAA before handling that data. Email providers have persistent access to ePHI — even end-to-end encrypted messages pass through their infrastructure at some point — which makes this requirement absolute, not situational. If a provider won’t sign a BAA, using them to send or store PHI isn’t a compliance risk you can mitigate; it’s a violation from the start.

Encryption as an addressable safeguard – Under 45 CFR §164.312(e)(2)(ii), the HIPAA Security Rule lists encryption of ePHI in transit as “addressable” rather than strictly “required.” In practice, this doesn’t mean optional, it means an organization must implement it, or document and justify an equivalent alternative safeguard. Enforced encryption has become the expected standard, and with the newly proposed HIPAA Security Rule planned for July 2027 publication, NPRM would formalize that expectation by making encryption of ePHI in transit and at rest mandatory rather than addressable. Organizations still relying on opportunistic TLS as their “equivalent alternative” should treat this as a closing window.

Access controls and audit logs – HIPAA requires the ability to track who accessed PHI, when, and what they did with it. This means role-based access permissions, multi-factor authentication, and a complete, retained audit trail — not just for compliance reporting, but for identifying and responding to incidents quickly.

The encryption safe harbor – This is one of the most consequential, and most underused, provisions in HIPAA. If PHI is sent via properly encrypted email and ends up misdirected to the wrong recipient, it is not a reportable breach under the Breach Notification Rule, because the encrypted content is considered unreadable and therefore not “unsecured PHI.” The exact same misdirection with unencrypted email is a reportable breach, triggering notification obligations to the individual and to HHS/OCR. Encryption isn’t just a security best practice here, it’s the line between a non-event and a formal breach investigation.

HITRUST certification as a trust signal – When evaluating vendors, HITRUST CSF certification is a strong external indicator that a provider’s security controls have been independently assessed against a recognized healthcare-specific framework. It’s not a HIPAA requirement in itself, but it meaningfully reduces the diligence burden on your side when vetting a provider.

Types of Healthcare Email That Must Be Secure

Not all internal debate here is about “should we secure email” — it’s about scope. Which specific email flows actually carry PHI, and therefore need to run through a compliant channel? In practice, the answer is broader than most teams initially assume.

Screenshot 2026 07 29 at 9.47.13 AM What Is Secure Email? The Complete Guide for Healthcare Organizations

The common thread: if a message references anything that could identify a patient in connection with health information — a name next to a diagnosis, an account number tied to a service date, an annual test reminder — it needs to move through a secure channel, regardless of whether it’s clinical, financial, or administrative in nature.

How to Evaluate a Secure Email Provider for Healthcare

Vendor evaluation in this category tends to go one of two ways: teams either take a provider’s “HIPAA-compliant” label at face value, or they get buried in RFP questions without knowing which answers actually matter. Ask these key questiosn to focus the evaluation on what’s operationally and legally significant.

“Does the provider sign a BAA? This is the first filter, not the last. If a vendor won’t sign a BAA — or offers a heavily limited one — everything else is irrelevant. Some organizations go a step further and negotiate indemnity or make-whole clauses into the BAA itself, seeking financial protection beyond the baseline liability allocation.

What encryption methods are supported? Confirm specifically whether the provider offers TLS only, or also supports S/MIME and/or PGP for end-to-end encryption where needed. TLS-only coverage is sufficient for most standard PHI communication; organizations with cross-border data sharing or especially sensitive use cases may need E2EE options available.

Is encryption enforced or opportunistic? This is the single most important technical question to ask directly, in those terms. A vendor that describes its encryption vaguely, without distinguishing enforced from opportunistic delivery, hasn’t answered the question. Push for specifics.

How are large attachments handled? Lab results, imaging files, and clinical documents often exceed standard attachment size limits. Confirm the provider has a secure, compliant method for large file transfer that doesn’t force users onto an unencrypted workaround.

What audit logging and reporting capabilities exist? You need visibility into delivery, access, and any failed encryption attempts, not just a generic sent/received log. Ask whether logs are retained for a period consistent with your organization’s HIPAA documentation requirements.

Do they support high-volume transactional email? Appointment reminders, billing notices, and patient communications at scale require infrastructure built for volume without sacrificing per-message compliance. Confirm the provider’s platform is built for this your specific pattern, not just person-to-person messaging.

Is the platform US-based with US data residency? For many healthcare organizations, where data physically resides — and under which jurisdiction — is a material factor in vendor risk assessment, particularly for payers and larger provider organizations with strict data governance policies.”

One operational factor worth weighing alongside these questions: secure email portals — the kind that require recipients to click through to a separate web page to read a message — solve the encryption problem but often create a real adoption problem. IT teams have reported a direct conflict between phishing-awareness training and portal-based workflows: staff and patients trained not to click suspicious links in emails are, understandably, reluctant to click the “secure link” a portal email contains. This is a legitimate reason many organizations increasingly prefer platforms that enforce encryption transparently in the background — like LuxSci’s SecureLine encryption technology — rather than routing every message through a separate portal experience.

Secure Email Checklist for Healthcare Organizations

Every safeguard covered in this guide comes down to a handful of concrete, verifiable actions. Use the checklist below as a working reference for what needs to be in place across your legal agreements, technical controls, and internal processes. This is not a one-time setup task, but something worth revisiting as your email volume, vendors, and regulations evolve. Share it across your compliance and IT teams as a starting point for an internal audit.

Legal and Contractual – BAA signed with email provider and all third-party vendors handling PHI.
Encryption – Forced TLS, not opportunistic only for emails in transit and all stored data encrypted with AES-256 bit encryption.
Access and Audit – Unique user IDs, role-based access, and login monitoring with advanced MFA enabled for all email accounts; audit logs active and maintained.
People and Processes – Staff trained in PHI handling, established breach response plan, annual email security policy review.

What Should I Do Now?

Secure email isn’t a single setting you switch on — it’s a combination of enforced encryption, a signed BAA, access controls, and documented process working together. Get any one piece wrong, and the rest doesn’t hold up under an OCR audit or a breach investigation.

If your organization is still relying on opportunistic TLS, an unsigned or incomplete BAA, or a patchwork of workarounds to move PHI through email, now is the time to close that gap, especially with the proposed 2025 HIPAA Security Rule update poised to make encryption a mandatory requirement rather than an addressable one in 2027.

FAQs

1. Is email HIPAA compliant?

Email can be HIPAA compliant, but only when the right safeguards are in place — enforced encryption, a signed BAA with your email provider, access controls, audit logs, and staff training on PHI handling. Standard email without these safeguards is not compliant.

2. Do I need to sign a BAA with my email provider?

Yes. Email providers have persistent access to ePHI — even encrypted messages pass through their servers — making them Business Associates under HIPAA. A signed BAA is required. If your provider won’t sign one, you cannot legally use them to send or store PHI.

3. What is the difference between opportunistic TLS and enforced TLS — and which does HIPAA require?

Opportunistic TLS attempts encryption but falls back to plaintext if the recipient’s server doesn’t support it. Enforced TLS stops delivery rather than sending unencrypted. HIPAA’s Security Rule treats transmission encryption as an addressable specification, in practice, enforced TLS is the standard auditors and OCR expect. The proposed 2025 HIPAA Security Rule NPRM would make encryption of ePHI in transit a mandatory requirement in 2027.

4. What happens if I send PHI in an unencrypted email?

It is an impermissible disclosure under HIPAA’s Privacy Rule and triggers the Breach Notification Rule, requiring you to notify the individual and HHS/OCR within 60 days. Penalties range from $100 to $50,000 per violation. Had the email been properly encrypted, the same incident would qualify for HIPAA’s encryption safe harbor, meaning no notification required.

5. Is Gmail or Microsoft 365 HIPAA compliant for sending patient emails?

Neither is compliant in their default configuration. Both use opportunistic TLS, meaning PHI can be sent in plaintext if the recipient’s server doesn’t support encryption. A signed BAA is available on enterprise plans but doesn’t close the technical gap alone. A purpose-built HIPAA-compliant email platform is the reliable solution.

HIPAA Security Rule Update: Email Encryption Rule Delayed to 2027

If you’ve been waiting for the final word on the new HIPAA Security Rule before you touch your email encryption strategy, you now have an official reason to keep waiting.

Our advice: Don’t do it.

What is the new HIPAA Security Rule for ePHI?

The Department of Health and Human Services’ Office for Civil Rights had targeted May 2026 for a final rule implementing the most significant update to the HIPAA Security Rule in over two decades. The proposal eliminates the “addressable” standard and makes encryption of ePHI in transit and at rest mandatory for every covered entity and business associate. That deadline came and went quietly. Now we know why: an updated federal regulatory agenda shows OCR’s timeline has moved to July 2027, with the rule-making downgraded from “final rule stage” to “long-term action.” OCR is still working through more than 4,700 public comments on the January 2025 proposal.

For an industry that had been expecting a tighter deadline, a year-plus delay is the kind of news that invites a collective exhale — and a shelved project plan. At LuxSci, we think that would be a mistake, for three reasons:

The current rule already requires you to address encryption. “Addressable” was never “optional.” It has always meant you must implement the safeguard, implement an equivalent alternative, or document in writing why neither is reasonable for your organization. Most healthcare organizations have never done that documentation rigorously, and OCR’s existing enforcement authority applies today, not in 2027.
Breach costs haven’t waited for the rule. IBM’s 2025 Cost of a Data Breach Report puts the average healthcare breach at $7.42 million, still the highest of any industry. At the same time, email remains the number one attack vector into healthcare organizations. None of that risk is paused by a regulatory delay.
Delay is not withdrawal. OCR has not signaled it’s abandoning the encryption mandate, only that it’s taking longer to finalize it. Organizations that build now toward the standard already proposed will be ahead (and more secure) regardless of exactly when, or in what final form, the rule lands. Organizations that wait risk a compressed scramble once it does.

What should healthcare IT and compliance leaders actually do with this news?

Reevaluate your ePHI security posture, recalibrate its urgency, and use the extra runway to do the job right, instead of racing against a deadline. This includes:

Getting a real inventory of where ePHI moves by email today, inbound and outbound, and where encryption is inconsistent or absent.
Closing the documentation gap on “addressable” now, while you have time to do it well rather than defensively.
Pushing your email vendor for concrete answers on encryption standards, MFA enforcement, audit logging, and breach notification — the same technical controls the proposed rule would make mandatory.
Building (or updating) a written, enforcement-ready posture: policies, vendor agreements, certifications and verifications, test results, and training records that would hold up under an OCR investigation today, not just in a future compliance deadline.

HIPAA Security Rule Email Encryption Requirements

Your Email Platform Is Becoming Critical Healthcare Infrastructure

July 1, 2026
Pete Wermter

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

Today, however, that view is rapidly becoming outdated.

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

Email Is No Longer Just a Messaging Tool

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

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

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

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

The Stakes Continue to Rise

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

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

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

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

AI Is Raising the Bar Even Higher

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

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

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

Generating more personalized emails means little if organizations cannot:

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

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

Infrastructure Matters More Than Features

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

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

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

Questions increasingly include:

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

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

Email and the Future Of Secure Healthcare Communications

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

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

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

LuxSci vs. Paubox: How to Choose the Right HIPAA-Compliant Email Provider

January 29, 2025
LuxSci

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

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

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

LuxSci vs. Paubox: Evaluation Criteria

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

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

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

LuxSci vs. Paubox: How They Compare

Data Security and Compliance

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

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

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

Performance and Scalability

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

Infrastructure

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

Marketing capabilities

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

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

Ease of use

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

Other HIPAA-compliant Products

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

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

HIPAA-Compliant Email: 7 Use Cases for In-Home Care

February 3, 2025
Pete Wermter

The demand for in-home care is growing as patients increasingly seek personalized, convenient healthcare in the comfort of their homes. A key reason for this increase is the rise in the number of baby boomers, i.e., people aged 65 and older, opting for in-home care.

In fact, as of 2020, there were approximately 76.4 million Baby Boomers in the United States, with projections indicating that by 2040, there will be roughly 80.8 million Americans over the age of 65. Consequently, the need for in-home care services will only grow to accommodate the health needs of this expanding demographic.

For in-home care providers, remaining competitive in this space requires increased levels of patient engagment over digital channels and the inclusion of protected health information (PHI) to personalize communications. As a result, incorporating secure, HIPAA-compliant email communications and campaigns into your in-home patient outreach efforts both enhances engagement and yields significant operational and financial benefits.

In this post, we explore 7 impactful use cases for HIPAA-compliant secure communications for in-home care, including how providers can harness them to achieve their efficiency goals and growth objectives, while improving health outcomes for patients.

What Are the Benefits of HIPAA-Compliant Email for In-Home Care Providers?

Before we dive into the most common email use cases for in-home care providers, let’s look at why adopting secure, personalized communication strategies offer several advantages:

Avoiding the Consequences of HIPAA Non-compliance: including sensitive patient data in communications without implementing the security measures required by HIPAA can incur financial (fines, compensation), operational (time spent mitigating security threats), and reputational (being seen as untrustworthy with PHI) consequences.
Enhanced Efficiency and Outcomes: streamlined communications, such as automated appointment reminders, reduce administrative tasks and missed appointments, allowing staff to spend more of their time engaging patients to drive better health outcomes.
Improved Patient Satisfaction: timely, relevant, and personalized communications demonstrate a commitment to patient well-being and positive engagements, fostering trust and loyalty.
Cost Savings: Secure, personalized communications lead to significant cost reductions by preventing miscommunications and the resulting complications.
Increased brand connection: with HIPAA-compliant communications, you can foster a better understanding of the full extent of your capabilities, the value you provide, and, ultimately, the vital role you play in your patients’ healthcare journey.

High-Impact HIPAA-Compliant Use Cases for In-Home Care

1. Appointment Reminders

Missed appointments are a substantial financial burden on healthcare organizations. In the U.S., they result in an estimated $150 billion in losses annually, with each no-show costing businesses approximately $200 per hour.

Sending personalized, secure appointment reminders via HIPAA-compliant email and text messaging can significantly reduce no-show rates, cutting costs, boosting revenue, and, most importantly, increasing patient adherence to care. Better still, appointment reminders can be automated, e.g., with confirmations sent at the time of booking and reminders scheduled to go out a few days before the appointment. This not only ensures consistent communication, with minimal additional administrative overhead, but also increases the utility and value of the in-home care service.

2. Follow-Up Communications

Frequent follow-up email communications are an effective way to monitor a patient’s progress, ensuring adherence to treatment plans and enabling them to adapt a health regime according to potential changes in their condition.

A few examples of situations that warrant a follow-up email include:

After an initial consultation
After an appointment with an in-home care professional
After a treatment or surgery
After in-home medical equipment training
After a patient has started a new course of medication

Follow-up email communications could include advice on booking a subsequent appointment, aftercare advice, or guidelines for taking medication. Again, as with appointment reminders, follow-up emails can be automated to streamline the process.

3. Personalized Treatment Plans

Tailoring treatment plans to fit a patient’s specific needs enhances treatment efficacy and reduces the likelihood of adverse effects. Secure email plays a crucial role in the development and distribution of treatment plans, which always include PHI, providing a channel by which healthcare providers can share sensitive patient data quickly and coordinate on any courses of action.

Email security measures, such as encryption, access control, and user authentication protect patient data from the malicious efforts of cybercriminals, while ensuring compliance with HIPAA’s Security Rule.

4. Care Coordination

Effective care coordination is essential for in-home care success where multiple healthcare professionals, such as nurses, therapists, and caregivers, must consistently collaborate to deliver high levels of patient care.

Offering critical functions such as treatment updates and emergency alerts, HIPAA-compliant email communications can ensure that all necessary parties remain in the loop about any situations regarding their shared patients. Additionally, integrating HIPAA-compliant email with a customer data platform (CDP) solution, electronic health record (EHR) systems, or any other system where PHI resides, allows in-home care providers to access and update patient records in real time, ensuring access to up-to-date information across the care team.

5. Proactive Patient Education

Educating patients through secure, personalized communications helps to enhance their competence in matters regarding their health, thereby increasing confidence in their ability to manage their healthcare journey more effectively, and resulting in greater engagement. Using PHI to segment patients by their condition or certain demographics (e.g., age, gender, lifestyle factors) and send them relevant educational materials is a powerful way for in-home care providers to offer additional value. This could include:

Advice on managing a particular condition of injury, e.g., chronic disease management
Informing patients and customers of events related to their present state of health, e.g., classes for expectant mothers, support groups for cancer patients, etc.
Tips related to improving their health according to recent diagnoses and known lifestyle factors, e.g., smoking cessation strategies, dietary advice, etc.

Patient education is such an effective use of HIPAA-compliant email because it can be done frequently. Plus, it offers the additional benefits of helping to position the in-home care provider as an expert, increasing patient trust and boosting adherence to prescribed health advice.

6. Collecting Patient and Customer Feedback

Another simple, yet powerful use of secure email communication is to collect feedback and intelligence from patients, via integrated, secure email and forms, for review requests, surveys, and polls. By gaining insight into how your patients and customers feel about the quality of your in-home care products and services, you can pinpoint areas for improvement. As well as increasing customer satisfaction levels, this will also present opportunities to root out inefficiencies and cut costs in the process.

Additionally, asking for feedback helps increase patient trust, because you’ve displayed a commitment to improving your service and that you’re interested in the opinion of your patients and customers.

7. Health Alerts

HIPAA-compliant email is a helpful tool for making patients aware of situations or circumstances that could adversely affect their health. This could include alerts about virus outbreaks in their area or adverse weather events that could affect their in-home healthcare provision. To maximize value, these email alerts can be paired with advice to help patients through potential health emergencies, such as information on vaccine drives, activities to avoid during a period of rough weather, and support resources should they require more assistance.

Is SendGrid HIPAA-Compliant?

January 23, 2025
LuxSci

Twilio’s SendGrid is a cloud-based email marketing platform that contains the tools and resources that organizations need to carry out bulk email marketing campaigns. By providing companies with a robust, scalable email infrastructure, SendGrid reduces the technical and management overhead from delivering emails at scale.

SendGrid’s capabilities and benefits are undeniable – and are the reason why the popular platform is the email delivery service of choice for prominent companies like Spotify and Airbnb. For healthcare organizations, however, while reliability and scalability are essential for large-scale patient engagement campaigns and communications, security is another crucial concern. More specifically, for a healthcare company to send electronic protected health information (ePHI) through an email services platform, the service must be HIPAA-compliant.

This then begs the question, is SendGrid a HIPAA compliant email service? Subsequently, can companies use SendGrid to transmit ePHI?

The short answer is no, they are not. Let’s take a closer look…

Is SendGrid HIPAA-Compliant?

SendGrid is not a HIPAA-compliant email service. There are two key reasons for this:

It lacks sufficient encryption measures
SendGrid does not sign business associate agreements (BAAs)

Let’s discuss each reason in greater detail.

Basic Encryption

SendGrid only offers the basic encryption provided by the Simple Mail Transmission Protocol (SMTP), i.e., the standard mechanism used to transmit emails.

Unfortunately, this level of encryption leaves ePHI vulnerable to cyber threats such as business email compromise (BEC) attacks, ransomware, and device loss or theft. In contrast, for an email services platform to be HIPPA-compliant, it must protect ePHI in transit and at rest, using security measures like Transport Layer Security (TLS) encryption and end-to-end encryption.

Refreshingly, SendGrid is clear and upfront about this (in contrast to, Mailchimp, for example, who make you dig a little deeper to determine their non-compliance) – as Twilio’s documentation explicitly says that they do not offer HIPAA-compliant data transmission. Stating, “SendGrid does not natively support HIPAA-compliant data transmission. We do not offer any encryption or security measures surrounding message transmission beyond those included in the SMTP RFC, which was not designed with HIPAA compliancy in mind.”

In short, SendGrid wasn’t designed to withstand the increased cyber risk that accompanies handling ePHI and isn’t HIPPA-compliant as a result.

No Business Associate Agreement

Additionally, in addition to lower levels of encryption, SendGrid does not sign the business associate agreements (BAA) required to be HIPPA-compliant.

A business associate agreement (BAA) is a written contract between a covered entity (your company) and a business associate (a service provider, such as an email services or email marketing platform) that’s an essential requirement of HIPAA compliance. A BAA details how two organizations can share data and the legal responsibilities of each party.

This is again stated on Twilio’s website that says, “Twilio SendGrid does not intend uses of the Service to create obligations under The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), the Gramm-Leach-Bliley Act (“GLBA”) or similar laws and makes no representations that the Service satisfies the requirements of such laws. If You are (or become) a Covered Entity or Business Associate (as defined in HIPAA) or a Financial Institution (as defined in GLBA), You agree not to use the Service for any purpose or in any manner involving Protected Health Information (as defined in HIPAA) or Nonpublic Personal Information (as defined in GLBA).”

Here, Twilio is explicitly telling you that SendGrid does not fit the requirements of HIPPA-compliant and that you should not use their service to transmit ePHI.

HIPAA-Compliant Alternatives to SendGrid

While healthcare companies cannot rely on popular options like SendGrid if they want to utilize ePHI in their patient outreach campaigns, fortunately, there are HIPAA-compliant email platforms that are specifically designed for organizations that have to comply with the regulations.

As the most experienced HIPAA-compliant email provider, LuxSci specializes in providing secure and scalable HIPAA-compliant services for companies aiming to send hundreds of thousands – or millions – of emails. In light of this, we place security, regulatory and practical considerations front and center when building our solutions – from their early planning stages until final deployment.

Our approach results in tailor-made tools and services like HIPAA-compliant bulk email, secure text and secure marketing. This includes flexible encryption functionality, such as TLS, end-to-end, or role-based access encryption, that enable healthcare organizations to align their security with the sensitivity of the transmitted and their specific business requirements – all while remaining HIPAA compliant.
