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

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.

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

May 12, 2026
Pete Wermter

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

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

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

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

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

For healthcare email security, the implications are significant.

Email = Healthcare Cybersecurity Risk

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

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

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

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

Recent OCR enforcement actions increasingly reflect these realities.

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

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

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

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

Email Encryption Is Moving From Addressable to Required

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

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

For healthcare email specifically, this creates several growing expectations:

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

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

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

Traditional MFA May No Longer Be Enough

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

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

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

For email environments, organizations should increasingly evaluate:

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

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

OCR Wants Proof, Not Just Policies

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

For email systems, organizations should be prepared to demonstrate:

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

This represents a broader shift in healthcare cybersecurity expectations.

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

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

Healthcare Organizations Need a New Email Security Strategy

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

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

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

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

Patient Engagement ROI: The Business Case for Secure Email in Healthcare

April 28, 2026
Pete Wermter

Every IT investment in healthcare today is being evaluated through a sharper lens.

Budgets are tighter. Expectations are higher. AI is the shiny object. Across healthcare organizations, leadership is asking the same question: how does this investment drive measurable results?

That’s where Patient Engagement ROI comes in, and where many traditional approaches fall short.

The Hidden Cost of Ineffective Communication

Patient engagement isn’t just a healthcare priority. It’s a financial one.

Missed appointments, gaps in care, and low response rates all translate directly into increased costs, operational inefficiencies, and a poor patient experience. Yet many organizations still rely on fragmented, manual, or non-personalized communication strategies.

Why?

For many, it’s because of uncertainty around HIPAA compliance, and what’s allowed and not allowed. Too often, healthcare IT and marketing teams avoid using valuable patient data to avoid security and compliance risks, especially over the email channel. The result is often generic outreach that fails to connect, and fails to deliver meaningful results, such as better health outcomes, fewer missed appointments, and increased sales.

How Secure Email Delivers ROI in Healthcare

Among all healthcare IT investments, secure email stands out for one reason: it directly impacts both patient engagement and staff and process efficiency.

With the right HIPAA-compliant marketing automation platform, secure email enables organizations to:

Deliver personalized, relevant messages using PHI data in their emails
Automate outreach at scale with triggered, engagement-driven campaigns
Improve patient response rates and adherence for better outcomes
Reduce manual workload across teams for greater productivity

This is where patient engagement ROI becomes tangible.

Instead of one-size-fits-all messaging, organizations can connect with patients based on unique needs and health conditions, such as appointments, care plans, preventative care reminders, new product needs, and more. And because it’s automated, these improvements scale without adding to workloads.

Turning Compliance into Better Outcomes and Growth

HIPAA is often viewed as a constraint. In reality, it’s an opportunity. If you have the right tools.

At LuxSci, we focus exclusively on secure healthcare communications, helping organizations safely unlock the value of their data and communications. Our solutions are designed to remove the friction between compliance and communication, so you don’t have to choose between security and growth.

With capabilities like flexible encryption, advanced segmentation, and high-volume delivery, secure email marketing becomes more than a safeguard, it becomes a growth driver.

And with industry-leading security performance and recognition, organizations can trust that their communications are protected at every level with LuxSci.

Scaling Patient Engagement ROI with Automation

The real power of secure email comes when it’s combined with automated healthcare workflows.

HIPAA compliant marketing automation allows you to build multi-step, data-driven patient journeys that run continuously in the background, taking adaptive steps based on each individual’s email engagement activity. This can include:

Appointment reminders that reduce no-shows
Follow-up communications that improve outcomes
Preventative care outreach for check-ups, annual test and care reminders
New product offers, upgrades and promotions
Educational email campaigns that drive long-term engagement and better health

Each interaction is an opportunity to improve both patient experience and your financial performance. Over time, these incremental gains compound, resulting in significantly higher patient engagement that delivers real value to your business.

Why Act Now?

Healthcare organizations can no longer afford IT investments that don’t deliver clear, measurable value. Secure email, powered by HIPAA compliant marketing automation, offers one of the most direct paths to improving engagement, efficiency, and outcomes, all while maintaining the highest standards of security.

Ready to see how LuxSci secure email can transform your patient engagement into real ROI?

What Is B2B Marketing in Healthcare?

April 27, 2026
Erik Kangas

B2B marketing in healthcare describes the promotion of products and services to healthcare businesses rather than to patients or the public. The audience can include provider groups, payers, laboratories, medical suppliers, health technology firms, and service companies working across the sector. The work calls for a more measured approach than many other business categories because buying decisions tend to involve several stakeholders, internal review, and close attention to data handling, workflow impact, and commercial fit. Good execution depends on clear communication, useful content, and a strong sense of how healthcare organizations evaluate change.

Why healthcare buying requires a different approach

Healthcare companies rarely move through a buying process in a straight line. One person may open the conversation, though several others can influence whether it goes any further. Finance may want a clearer commercial case. Operations may focus on staffing, efficiency, and implementation pressure. IT may look at access, system fit, and data management. Compliance teams may review privacy implications or contractual language. B2B marketing in healthcare works better when the writing reflects those realities early. Buyers are looking for material that helps them assess risk, discuss options internally, and move forward with fewer unanswered questions.

A Difference in stakeholder priorities

A single account can contain several audiences at once. That is part of what makes this area demanding. A hospital operations leader may care about throughput and day to day workflow. A payer executive may be more interested in administrative efficiency or review times. A supplier may focus on coordination, ordering processes, or communication across partner relationships. Content becomes stronger when it takes those different perspectives seriously. The message does not need to become overly technical. It needs enough accuracy and relevance for each reader to feel that the company understands the conditions attached to their role.

Why credibility matters in every channel

Healthcare buyers tend to read promotional material carefully. They notice vague claims, inflated language, and unsupported promises very quickly. That is why credibility has to be built into the writing itself. A clean explanation of a business problem can carry real weight. A grounded case example can help a reader picture how a solution would work in practice. Clear language around implementation, support, privacy, or service structure can also help keep the conversation moving. When protected health information enters the picture, HIPAA may become part of the review as well, especially for companies handling regulated data or supporting covered entities and business associates.

Content to support real decisions

The most useful assets in this space are the ones that help buyers think more clearly. An article can frame a problem in a way that supports internal discussion. An email sequence can keep a company visible while review is taking place. A service page can answer practical questions before a meeting is booked. B2B marketing in healthcare gains traction when content has a clear job and a clear reader. That focus usually produces stronger engagement than broad copy built around generic thought leadership language. Buyers respond well to material that respects their time and gives them something worth passing along.

What strong performance looks like

Success in healthcare is rarely captured by surface numbers alone. Traffic and opens may show that content has reached people, though those signals do not say much on their own about buying intent. Better indicators include repeat visits from the same organization, replies from relevant contacts, deeper engagement with security or implementation pages, and growing activity across several stakeholders in one account. Those patterns can tell commercial teams where interest is becoming more serious. B2B marketing in healthcare proves its value when it helps those teams follow up with better timing, better context, and material that fits the next stage of evaluation.

Is Mailchimp HIPAA Compliant?

October 10, 2024
LuxSci

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

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

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

IS MAILCHIMP HIPAA COMPLIANT?

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

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

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

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

MAILCHIMP: NO BUSINESS ASSOCIATE AGREEMENT

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

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

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

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

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

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

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

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

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

Understanding Business Associate Agreements (BAAs) and Shared Responsibility

September 9, 2025
Pete Wermter

Modern-day healthcare organizations rely on a growing array of partners and vendors to provide them with the tools they need to effectively serve patients and customers.

However, while new digital solutions and healthcare ecosystems often result in greater productivity and efficiency, they also increase the number of third parties a company must communicate with and share protected health information (PHI), requiring a business associate agreement (BAA). Unfortunately, this increases the risk of PHI being exposed, as it increases a healthcare organization’s supply chain network and the number of external organizations with access to their data, significantly raising the risk of a security breach.

This is where the concept of shared responsibility comes in.

In this article, we explore the shared responsibility model for data security, explaining the concept, the role of a BAA in shared responsibility, and why healthcare companies need to know how it works and where it factors into their HIPAA compliance efforts.

What Is The Shared Responsibility Model?

Shared responsibility is a core data security principle that divides the responsibility for protecting data between a company that collects the data and a vendor that supplies the infrastructure or systems used to process said data.

The shared responsibility model grew in prominence as more companies moved to cloud-based environments and applications. In the past, when companies kept their systems and data onsite, they had more control over who could access their data and, subsequently, a better ability to mitigate data security risks.

However, in adopting cloud-based infrastructure and applications, companies have to process and store their data in the cloud – often in shared infrastructure with other vendors using the same cloud – which consequently shifts some of the responsibility of information security to the cloud service provider (CSP) itself. This marked a profound shift in the way data was handled, transmitted, and stored – necessitating an evolved approach to data security.

This fundamental shift in the way companies consume infrastructure and use apps ushered in the shared responsibility model: Where the cloud vendor provides the infrastructure or application, including HIPAA compliant and high secure environments, but it’s still the responsibility of the client to configure and use it securely.

Business Associate Agreements (BAAs) and Shared Responsibility

By detailing the respective responsibilities of healthcare companies or Covered Entities (CEs) and their vendors or Business Associates (BAs) in securing PHI, a Business Associate Agreement is a prime example of shared responsibility.

For example, the Business Associate shoulders the responsibility of providing the data safeguards required by HIPAA to secure patient data, such as infrastructure, encryption, audit logging, and even physical onsite security.

The Covered Entity, meanwhile, is responsible for conducting risk assessments, defining access control policies and processes, configuring services accordingly, workforce training, and continuous monitoring.

Additionally, both parties have the obligation to report security incidents to each other, as well as being independently accountable to the U.S. Department of Health and Human Services (HHS).

Why Shared Responsibility Is Essential for HIPAA Compliance

For healthcare companies, having a firm grasp of the shared responsibility model for safeguarding and securing PHI, and how they fit within your overall security posture is essential (for two key reasons).

Security Gaps

Firstly, clearly understanding the shared responsibility decreases the likelihood of security gaps. If CEs are under the impression that the vendor handles all aspects of data security, they won’t be as vigilant. They’ll be less inclined to configure services, educate their staff accordingly, pay appropriate attention to vendor security alerts, etc.

But the same is also true for BAs: If they assume their client does most of the heavy lifting in securing the data disclosed to them, they could be remiss in their duties to protect it. Without shared responsibility, each side simply assumes the other is covering a safeguard, opening the door for security gaps that malicious actors can exploit.

Fortunately, by detailing both parties’ (CEs and BAs) responsibilities and liabilities regarding data protection, a BAA removes this ambiguity and, more importantly, reduces the risk of security gaps. It’s critical to know the details and work with vendors building products for compliance versus implementing a tick-box approach to compliance that places too much burden on the CE.

Covered Entities (CEs) Are Ultimately Accountable

Subsequently, the second reason why it’s essential for CEs to understand the shared responsibility model, and increase their cybersecurity readiness accordingly, is that it’s the CE that’s ultimately held accountable for data breaches.

Mistakenly thinking that a BAA automatically makes them compliant may result in healthcare companies underinvesting in training, monitoring, and incident response. Conversely, understanding that even with a BAA in place, they’re the ones primarily accountable for protecting PHI gives them a greater sense of urgency to properly implement HIPAA compliant security measures.

The Covered Entity’s Role Within Shared Responsibility

Let’s look at the ways that healthcare companies have to hold up their end in the shared responsibility model.

Choose Compliance-Conscious Vendors

First and foremost, companies have to choose the right vendors to supply them with HIPAA compliant services and solutions.

Look for companies that market themselves as HIPAA compliant and display a detailed understanding of HIPAA requirements, particularly the HIPAA Security Rule. Do your due diligence and perform deeper dives on potential vendors, researching their stated security features, reviews from existing clients, whether they have certifications like HITRUST – and if they’ve been involved in any data breaches.

Naturally, a core prerequisite of being a HIPAA compliant vendor is being willing to sign a BAA, so you can immediately rule out any vendors not willing to do so. For instance, some healthcare companies may assume they can use widely adopted solutions such as SendGrid, Mailchimp, but they don’t offer a BAA.

Once you’ve confirmed a vendor offers a BAA, look through it to establish its terms and determine if it covers the services you’re interested in.

Configuration

Another core component of shared responsibility is comprehensive configuration management. While the BA’s responsibility is to provide a secure solution that satisfies HIPAA requirements, it’s the CE’s responsibility to configure it securely to fit within their IT ecosystem.

Features that often require configuration include:

Access control: Role-based access, Zero Trust, Multi-Factor Authentication (MFA).
Encryption settings: Enabling encryption, choosing encryption type, enforcing forced TLS, enabling storage encryption.
Feature restrictions: Disabling default configurations that enable integration with non-compliant tools.
Audit logging: Enabling audit logging and configuring log formats.
Retention settings: How long to retain audit logs and who is permitted to review them.

Finally, establishing a patch management strategy, i.e., when and how your organization applies software updates, is an important element of configuration. While the vendor must release updates to fix security vulnerabilities discovered in their solutions, it’s up to healthcare companies to deploy the patches.

Training

Regardless of how many security features a vendor bakes into their solutions, once deployed by a healthcare company, the tool is only as secure as the practices of their least security-conscious employee. Consequently, companies must train their staff on how to properly use a solution to process protected health information and sensitive data. The more an employee is required to handle PHI, the more thorough and frequent their training should be.

Key aspects of comprehensive cybersecurity training include:

Common cyber threats: what the most prevalent cyber threats are and how to recognize them.
Incident response: how to report a suspected security incident, i.e., who to contact and when.
Specific solution training: how to securely use systems that process PHI
Scope awareness: knowing which services within your organization’s IT ecosystem are HIPAA-compliant and which are not

Reporting

Although both healthcare companies and BAs have notification obligations to the HHS in the event of a data breach involving PHI, it’s the CE that bears most of the investigative burden.

Firstly, while a BA may report a security incident, it’s the CE’s responsibility to conduct a risk assessment to determine the probability of compromise of PHI, assess risk, and determine whether an official notification of a breach to HHS is necessary.

Secondly, BAs must notify the CE without unreasonable delay and no later than 60 days after discovery. Although BAs often wait to complete internal investigations before notifying the CE, the CE’s 60-day clock starts upon the BA’s discovery, not upon the BA’s report. Therefore, BA delays can create compliance risks for the CE.

To prevent this, where possible, you can include stricter contractual reporting timelines in the BAAs. This constantly keeps your company in the loop, ensuring you have sufficient lead time to complete your own investigations and your HIPAA-regulated deadlines.

What Is HIPAA Email Marketing?

May 13, 2025
Pete Wermter

HIPAA email marketing involves digital promotional communications sent by healthcare organizations that must comply with federal privacy regulations when using Protected Health Information (PHI) to reach patients and prospects. Healthcare providers can engage in email marketing activities, but they encounter strict limitations when using patient contact information obtained through clinical encounters or when targeting recipients based on health conditions. The HIPAA Privacy Rule requires written authorization for most email marketing that involves individually identifiable health information, while permitting certain treatment-related communications and health plan activities without patient consent.

Healthcare organizations increasingly rely on email communication to reach patients efficiently while managing costs and improving engagement. Carrying out effective digital marketing while adhering to privacy compliance requires understanding when authorization is needed and how to implement compliant email marketing strategies.

Why Healthcare Organizations Use Email Marketing

Cost efficiency drives healthcare email marketing adoption as organizations seek affordable ways to communicate with large patient populations. Email campaigns cost significantly less than direct mail, print advertising, or telephone outreach while providing measurable engagement metrics. Healthcare systems can reach thousands of patients instantly with preventive care reminders, health education materials, or service announcements at minimal expense per recipient.

Patient engagement improves through targeted email communications that provide relevant health information and service updates. Email marketing allows healthcare organizations to segment audiences based on demographics, health interests, or service utilization patterns. Personalized email content generates higher open rates and click-through rates than generic mass communications, leading to better patient response and participation in health programs.

Competitive positioning requires healthcare organizations to maintain visibility in patient inboxes alongside other service providers and health information sources. Patients receive numerous health-related emails from insurance companies, pharmaceutical manufacturers, wellness apps, and other healthcare entities. Organizations that do not engage in compliant email marketing may lose mindshare and patient loyalty to more communicative competitors.

Revenue generation opportunities emerge from email marketing campaigns that promote elective services, wellness programs, or expanded care offerings. Healthcare organizations can use email to announce new service lines, highlight specialist capabilities, or educate patients about treatment options. Revenue-generating email marketing requires careful attention to HIPAA authorization requirements to avoid compliance violations.

Healthcare Emails Requiring Patient Authorization

Promotional emails for elective services or non-treatment programs require written patient authorization when using contact information obtained through clinical encounters. Healthcare organizations cannot email patients about cosmetic procedures, weight loss programs, or wellness services without explicit consent, even when using their own patient databases. The authorization must specifically address email marketing and describe the types of services being promoted.

Third-party product promotions sent via email require patient authorization regardless of the healthcare organization’s relationship with the product manufacturer. Organizations cannot send emails promoting pharmaceutical products, medical devices, or health-related consumer goods without written patient consent.

Targeted health campaigns that use diagnostic or treatment information to select email recipients require authorization under HIPAA marketing rules. Healthcare organizations cannot send diabetes management emails to patients with diabetes diagnoses or cardiac health information to patients with heart conditions without written permission. The targeting based on health status distinguishes these campaigns from general health education communications.

Social event invitations and fundraising appeals sent via email may require authorization depending on how recipient lists are compiled and whether health information influences targeting decisions. Healthcare organizations can send general fundraising emails to broad patient populations but need authorization when targeting based on specific conditions, treatments, or service utilization patterns.

HIPAA Compliant Treatment-Related Emails

Appointment communications qualify as treatment-related emails that do not require marketing authorization under HIPAA regulations. Healthcare organizations can send appointment confirmations, reminders, and rescheduling notices without patient consent because these communications support ongoing care relationships. Follow-up appointment scheduling and routine care reminders also fall under permissible treatment communications.

Care coordination emails between healthcare providers remain exempt from marketing restrictions when they facilitate patient treatment. Primary care physicians can email specialists about patient referrals, and care teams can coordinate treatment plans via email without authorization requirements. The communications must relate directly to patient care rather than promoting additional services or programs.

Health education materials related to conditions that patients are receiving treatment for do not require marketing authorization. Healthcare organizations can email diabetes management tips to diabetic patients currently receiving care or send cardiac rehabilitation information to patients enrolled in cardiac programs. The education must relate to active treatment relationships rather than general health promotion.

Prescription and laboratory result communications via email support treatment activities and do not trigger marketing restrictions. Healthcare organizations can notify patients about prescription readiness, laboratory result availability, or medication adherence reminders without written authorization. Patient portal notifications about available health information also qualify as treatment communications.

HIPAA Email Marketing Compliance Supports

Encryption protection is necessary for all email communications containing PHI, whether for treatment or marketing purposes. Healthcare organizations must implement appropriate safeguards to protect patient information during email transmission and storage. Email marketing platforms used by healthcare organizations need encryption capabilities and security controls that meet HIPAA Security Rule requirements.

Access controls within email marketing systems ensure that only authorized personnel can access patient contact information and send marketing communications. Role-based permissions limit which staff members can create marketing campaigns, access patient lists, or modify email content. Multi-factor authentication adds security layers that protect against unauthorized access to email marketing platforms containing patient data.

Audit logging capabilities track all activities within HIPAA email marketing systems to create compliance documentation. The systems must log campaign creation, email sends, list access, and user activities to provide audit trails for regulatory reviews. Automated reporting features help healthcare organizations monitor email marketing compliance and identify potential privacy violations.

Opt-out mechanisms are required for all healthcare email marketing communications to provide patients with control over future messaging. Unsubscribe processes must be easy to use and honor patient requests promptly to maintain compliance with both HIPAA and CAN-SPAM regulations. Email marketing systems need automated processing of opt-out requests and suppression list management capabilities.

Obtaining Valid Email Marketing Authorization

Authorization documents for email marketing must include specific elements required by HIPAA Privacy Rule regulations. The authorization must describe what patient information will be used, identify who will receive the information, and explain the purpose of the email marketing communications. Patients must understand their right to revoke authorization and any consequences of refusing to provide consent for marketing activities.

Timing considerations affect when healthcare organizations can request email marketing authorization from patients. Authorization requests should not be bundled with treatment consent forms or presented during medical emergencies when patients cannot provide informed consent. Organizations need separate processes for obtaining marketing authorization that do not interfere with treatment decisions or patient care activities.

Electronic signature capabilities allow healthcare organizations to collect email marketing authorization digitally while meeting HIPAA documentation requirements. Patient portal systems, website forms, or tablet-based signature capture can facilitate authorization collection. Electronic authorization systems must provide adequate authentication and maintain signed documents for audit purposes.

Renewal procedures help healthcare organizations maintain current authorization for ongoing email marketing campaigns. Authorization documents should specify expiration dates or renewal requirements to ensure patient consent remains valid. Entities need systems to track authorization status and remove patients from marketing lists when consent expires or is revoked.

Compliance Challenges Affecting HIPAA Email Marketing

List management complexity creates compliance risks when healthcare organizations use multiple sources of patient contact information for email marketing. Patient lists derived from treatment encounters require different handling than lists compiled from website registrations or health screenings. Organizations need clear policies about which lists can be used for marketing purposes and which require patient authorization.

Content classification challenges arise when determining whether specific email communications qualify as treatment-related or marketing activities. Healthcare organizations may struggle to distinguish between educational content that supports treatment and promotional content that requires authorization. Legal review processes help organizations evaluate email content and determine appropriate compliance requirements.

Vendor management issues emerge when healthcare organizations use third-party email marketing platforms that may not understand healthcare compliance requirements. Marketing vendors need Business Associate Agreements and must implement appropriate safeguards to protect patient information. Organizations remain responsible for vendor compliance with HIPAA requirements even when using external email marketing services.

Cross-platform integration difficulties occur when healthcare organizations attempt to coordinate email marketing with other communication channels or healthcare systems. Patient authorization status must be synchronized across email platforms, patient portals, and electronic health record systems. Data synchronization challenges can create compliance gaps or duplicate communication efforts that frustrate patients and waste resources.

Enhanced Security: AES-256 Encryption for SSL and TLS

December 1, 2020
LuxSci

SSL and TLS play critical roles in securing data transmission over the internet, and AES-256 is integral in their most secure configurations. The original standard was known as Secure Sockets Layer (SSL). Although it was replaced by Transport Layer Security (TLS), many in the industry still refer to TLS by its predecessor’s acronym. While TLS can be relied on for securing information at a high level—such as US Government TOP SECRET data—improper or outdated implementations of the standard may not provide much security.

Variations in which cipher is used in TLS impact how secure TLS ultimately is. Some ciphers are fast but insecure, while others are slower, require a greater amount of computational resources, and can provide a higher degree of security. Weaker ciphers—such as the early export-grade ciphers—still exist, but they should no longer be used.

The Advanced Encryption Standard (AES) is an encryption specification that succeeded the Data Encryption Standard (DES). AES was standardized in 2001 after a five-year review and is currently one of the most popular algorithms used in symmetric-key cryptography. It is often seen as the gold standard symmetric-key encryption technique, with many security-conscious organizations requiring employees to use AES-256 for all communications. It is also used prominently in TLS. (more…)
