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

encrypted email transmission

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:

  1. The sender’s computer talks to the sender’s email or WebMail server to upload the message.
  2. The sender’s email or WebMail server then talks to the recipient’s inbound email server and transmits the message to them.
  3. 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:

  1. 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).
  2. Each Received line documents what a server did and when.
  3. 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

  1. 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:

  1. 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.
  2. 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.
  3. 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.

HIPAA Compliant Email

Here’s What HIPAA Compliant Email Salespeople Don’t Tell You

With email security threats continuously increasing in number and sophistication, as well as healthcare companies requiring secure solutions to communicate with patients and customers, the need for HIPAA compliant email solutions has never been greater. 

However, when looking for the right secure email services provider (ESP), healthcare organizations run the risk of making inaccurate assumptions about HIPAA compliance via what they learn from prospective vendors. This is due to the tendency for sales materials for HIPAA compliant email services, such as web pages or promotional videos, to highlight the strengths of the platform, while downplaying a healthcare company’s own role and responsibilities in securing protected health information (PHI). 

With this firmly in mind, here are six key things that HIPAA compliant email salespeople don’t tell you about securing communications and achieving compliance. 

1. The Shared Responsibility Model

Firstly, HIPAA compliant email salespeople are unlikely to emphasize the idea of shared responsibility when it comes to data security. This is the idea that two entities that share access to data, e.g., a healthcare company and their ESP, have a shared responsibility to preserve the privacy of that data.

In reality, most sales pitches explain the benefits and features of the solution, as opposed to stressing that compliance truly depends on how it’s configured and used. Now, that’s not to say that a salesperson is trying to hide this fact, as they’ll probably allude to training and configuration requirements. But, they’ll be less likely to make light of this and, more broadly, how shared responsibility factors into compliance.

2. A BAA Doesn’t Automatically Make You HIPAA Compliant

A business associate agreement (BAA) is essential for HIPAA compliance, but signing one doesn’t automatically make you compliant. Your organization still has to use the email delivery solution in a way that aligns with HIPAA regulations, which involves proper configuration, training, oversight, and reporting.

The misconception among some healthcare companies that a BAA equals compliance may be perpetuated by the term “HIPAA compliant email services provider”.  This could give some the impression that the vendor is fully HIPAA compliant and, subsequently, in signing a BAA with them, the use of their services is fully compliant.

But, it’s not that simple.

Simply signing a BAA obscures the real effort involved in achieving compliance. There’s no official HIPAA seal of approval, and HIPAA compliant means that the solution is capable of being configured for compliant use, which is a shared responsibility. HIPAA compliant email salespeople are unlikely to volunteer this nuance, especially if their email solution requires considerable configuration or has a steep learning curve to use it securely.

3. Not All Solutions or Features Are HIPAA Compliant

Another key detail often underplayed by vendor sales materials of HIPAA compliant email solutions is that some of their features, or even entire services, aren’t covered by their BAAs, so they can’t be used to handle PHI. 

These tools are referred to as “out of scope” and may include tools capable of integration with the email service, such as analytics or AI capabilities, but they don’t possess the cyber risk mitigation measures that align with HIPAA regulations. Perhaps the main reason for this is that many mass-market email delivery solutions, such as Microsoft 365 or Google Workspace, are designed for companies across all sectors. Consequently, while they can be HIPAA compliant, they weren’t developed from the ground up with the stringent regulatory demands of the healthcare industry in mind.

4. Solutions Are Not HIPAA Compliant “Out of The Box”

HIPAA compliant email salespeople may suggest that compliance is built into their platform, and healthcare organizations can use it to transmit PHI straight away, but this isn’t the case. Healthcare companies must still configure the email platform accordingly, as per the security requirements determined by their risk assessment, e.g., applying the right level of encryption. 

Also, if the email service is difficult to configure for HIPAA compliance or if the vendor’s configuration documentation lacks detail, that presents another obstacle to its compliant use. 

In addition to configuration, healthcare companies also have to implement access management controls and policies, establishing the extent to which each employee can access PHI in respect to their roles and responsibilities. From there, they will have to train their workforce on how to use the HIPAA compliant email solution securely, which may include those tools that fall outside the scope of your BAA with the vendor, and must not be used for the disclosure of patient data.

5. Essential Security Features Cost Extra 

Another more egregious version of an ESP not being HIPAA compliant out of the box is having features required for compliance, such as encryption or audit logging, as premium add-ons and not included in the solution’s base pricing. 

A vendor’s sales materials for its email service might list the necessary safeguards, but underemphasize the fact that only some versions of their platform are truly HIPAA compliant. Consequently, healthcare companies must confirm that the features required for HIPAA compliant email communications are included in the plan they’re purchasing. 

6. The Importance of Staff Training on HIPAA

HIPAA compliant email salespeople are often remiss in stressing the need for additional workforce training alongside the deployment of their platform. A healthcare company’s employees must be trained on how to securely use the email client, how to ID potential threats, and best practices for including PHI in email communications, as well as the regulations tied to HIPAA and data security.

This includes educating users on the differences between regular and secure email, and what they must do to safeguard patient and customer data. Fortunately, secure email solutions from providers like LuxSci enable automated email encryption, and users do not need to take any additional actions to ensure encryption when sending emails.

Additionally, in some cases, employees will need to be trained on which tools or features do not align with HIPAA guidelines and must not be used to process PHI.

LuxSci: Fully HIPAA Compliant – No Hidden Surprises

b2b medical marketing

What Does b2b Medical Marketing Help Healthcare Vendors Accomplish?

B2b medical marketing helps healthcare vendors to explain the practical value of a product to clinical and administrative buyers by presenting clear information that supports decision making across operational and regulatory domains. Buyers respond to communication that describes how a tool fits into routine workflows and how it handles information, and the process depends on steady explanations rather than promotional language.

Early Movement in the Buyer Relationship

The first stage of communication gives prospective buyers a clear sense of what the service does and why it belongs in their setting. Healthcare groups rely on predictable routines and they look for products that support those routines without creating unnecessary strain on staff. When an introduction explains how a tool fits into patient movement, documentation demands, or coordination between departments, readers can place the service into a familiar context. This lowers the cognitive effort required to evaluate whether further consideration is worthwhile and creates a smoother path for later discussions, which is why many vendors treat early stage explanations as the base of effective b2b medical marketing in this environment.

The Influence of Operational Structure

Clinical and administrative environments are shaped by long standing systems, varied software tools, and staff roles that have developed around known constraints. Vendors using b2b medical marketing describe how a product enters this environment so that the buyer can picture the transition from interest to adoption. Extended explanations of onboarding steps, data migration choices, and staff training routines help readers understand how daily operations shift when a new tool is introduced. These explanations allow decision makers to forecast workload changes rather than relying on assumptions, and they reflect the broader goal of b2b medical marketing which is to reduce uncertainty.

Regulatory Considerations in Vendor Communication

Healthcare buyers place great weight on regulatory matters, which is why clear descriptions of data handling are central to this type of communication. Readers look for information about access management, retention practices, audit preparation, and the path information takes through each component of a system. When vendors describe these areas in detail, compliance teams can perform early assessments and avoid long chains of clarification requests. This approach supports efficient internal review because the buyer gains confidence that the vendor maintains structured processes rather than improvised arrangements, and this clarity strengthens the overall impact of b2b medical marketing.

Reliability Expectations Within Clinical Settings

Healthcare settings cannot tolerate uncertainty in the systems that support patient care. B2b medical marketing provides insight into how a vendor manages service interruptions, planned updates, backup routines, and recovery efforts. A description of past events or internal procedures gives readers a sense of how the vendor behaves when conditions are difficult. Buyers place great value on this type of detail because it helps them differentiate between systems that hold up under stress and systems that falter when routine performance is disrupted, and these reliability discussions form a core thread in b2b medical marketing for clinical tools.

Perspectives That Influence Internal Decision Making

Each participant in the purchasing process evaluates a product through a different lens. Financial leaders consider long term spending patterns, clinical managers look for ease of use and effects on staff time, and compliance teams examine information practices. Communication that attends to these perspectives without shifting tone allows the reader to share information across departments with minimal friction. This prevents internal delays because each group can assess the service using information that relates to its role in the organisation, and thoughtful navigation of these viewpoints reinforces the strength of b2b medical marketing across healthcare markets.

The Role of Educational Content in Vendor Outreach

Healthcare groups respond well to educational material that speaks to challenges in clinical settings. Articles and guides that explain regulatory shifts, workflow bottlenecks, or mistakes observed in comparable organisations allow readers to examine their own processes. This form of communication helps buyers understand the vendor’s approach to problem solving and creates familiarity before any formal evaluation begins. Educational content performs well in this field because it demonstrates practical awareness rather than relying on abstract claims, making it a central component of many b2b medical marketing programs.

Use After Adoption

Decision makers frequently look beyond the moment of purchase and seek a clear view of the daily relationship that follows implementation. Communication describing staff support, update patterns, training formats, and communication channels helps buyers picture how the tool will fit into routine operations. Long paragraphs that describe the lived experience of using the service allow internal champions to advocate for the product with fewer unknowns, which supports faster movement through approval stages. This expectation of clarity after adoption aligns with the wider goals of b2b medical marketing which encourage predictable cooperation between vendor and buyer.

Documentation Supporting Review Processes

Healthcare organisations rely heavily on documentation during evaluation. Guides, records, administrative instructions, and explanations of data controls enable teams to examine the product without repeated requests for further detail. B2b medical marketing that introduces these documents early in the conversation reduces internal delays because reviewers can move through their procedures with all necessary information available at the outset. This transparent approach helps build trust between the vendor and the buyer and underscores the value of documentation as a recurring theme within b2b medical marketing.

B2b medical marketing works most effectively when vendors show an accurate grasp of clinical pressures and administrative realities. When communication reflects these conditions and acknowledges the challenges that healthcare groups experience during busy periods, readers gain confidence that the vendor understands the world they operate in. This supports deeper conversations about integration, performance, and long term cooperation across the organisation.

Understanding HIPAA Email Retention Requirements

HIPAA email retention requirements mandate that healthcare organizations preserve electronic Protected Health Information (ePHI) contained in email communications for specific time periods based on state and federal regulations. The HIPAA Privacy Rule requires covered entities to maintain documentation and policies related to patient information for at least six years from the date of creation or when last in effect. Email messages containing patient data become part of designated record sets and must be retained according to the same standards that apply to other medical records and administrative documents.

Healthcare organizations deal with complex retention obligations that vary by state, with some requiring longer preservation periods than the federal minimum. Understanding HIPAA email retention requirements helps organizations develop compliant policies while managing storage costs and operational efficiency.

Why Do Healthcare Entities Need Email Retention Policies?

Healthcare organizations need email retention policies to comply with legal obligations and support patient care continuity. Medical record laws in most states require healthcare providers to maintain patient information for specific periods, ranging from three years to indefinitely depending on the jurisdiction and type of information. Email communications that contain treatment discussions, appointment scheduling, or billing information become part of the medical record and fall under these retention requirements.

Litigation and regulatory investigations create additional drivers for email retention. Healthcare organizations may face lawsuits, malpractice claims, or regulatory audits that require access to historical communications. Courts can impose sanctions on organizations that fail to preserve relevant electronic communications, including email messages that contain patient information. The legal hold process requires organizations to suspend normal deletion procedures when litigation is anticipated or pending.

Patient care coordination benefits from accessible historical communications between providers, patients, and care teams. Retained email messages can provide context for treatment decisions, document patient preferences, and track care transitions between different providers or facilities. Quick access to communication history helps healthcare workers make informed decisions and avoid repeating previous discussions or recommendations.

Audit and compliance verification depend on comprehensive record retention that includes email communications. Regulatory agencies like the Office for Civil Rights may request documentation during HIPAA compliance investigations. Organizations that cannot produce required communications face potential violations and penalties. Strong retention policies ensure that audit trails remain intact and compliance documentation stays accessible throughout required timeframes.

Minimum Retention Period of HIPAA Emails

Federal HIPAA requirements establish a minimum retention period of six years for policies, procedures, and documentation related to patient information protection. This timeframe applies to administrative records rather than medical records themselves. Email communications that contain ePHI may need longer retention based on state medical record laws and the type of information contained in the messages.

State regulations create varying retention requirements that healthcare organizations must navigate. Some states require medical records to be retained for seven to ten years after the last treatment date, while others mandate longer periods for specific patient populations such as minors. Email communications that become part of the medical record inherit these extended retention requirements regardless of the federal HIPAA minimum.

Patient age considerations affect retention calculations for pediatric healthcare providers. Many states require medical records for minors to be retained until the patient reaches majority age plus an additional period, potentially extending retention requirements by decades. Email communications involving pediatric patients fall under these extended requirements when they contain treatment-related information.

Specialty practice requirements may dictate longer retention periods for certain types of healthcare information. Mental health records, substance abuse treatment communications, and occupational health information often have specific retention requirements that exceed standard medical record timeframes. Healthcare organizations practicing in these areas need policies that address the longest applicable retention period for their email communications.

What Types of Email Require HIPAA Retention?

Treatment-related email communications between healthcare providers require retention when they contain patient information or clinical decision-making discussions. Messages about diagnosis, treatment plans, medication management, and care coordination become part of the medical record. Email consultations between specialists, primary care providers, and other members of the healthcare team need preservation to maintain complete treatment documentation.

Administrative email communications containing patient information also fall under retention requirements. Appointment scheduling messages, insurance verification communications, and billing inquiries that include patient identifiers become part of designated record sets. Staff discussions about patient care policies or quality improvement initiatives may require retention depending on their content and regulatory implications.

Patient communication emails need careful evaluation to determine retention requirements. Direct email exchanges between patients and providers about symptoms, treatment questions, or care instructions become part of the medical record. Portal notifications, appointment reminders, and educational materials sent to patients may also require retention based on their content and relationship to patient care.

Business partner communications involving patient information require retention consideration under Business Associate Agreement terms. Email exchanges with laboratories, imaging centers, billing companies, and other business associates may contain patient information that falls under retention requirements. Organizations need clear policies about which communications with external partners require preservation and for how long.

How to Implement HIPAA Email Retention Systems

Email archiving systems provide automated solutions for capturing and preserving healthcare communications that contain patient information. Modern archiving platforms can identify emails containing ePHI through content analysis, keyword detection, and sender/recipient patterns. The systems automatically route qualifying messages to secure storage while applying appropriate retention schedules based on content type and regulatory requirements.

Legal hold capabilities within email retention systems allow healthcare organizations to suspend normal deletion schedules when litigation or investigations require preservation of communications. The systems can place holds on specific custodians, date ranges, or keyword-identified communications while maintaining normal retention processing for other messages. Legal hold functionality helps organizations avoid spoliation sanctions while managing ongoing retention obligations.

Search and retrieval functionality enables healthcare organizations to locate specific communications quickly during audits, litigation, or patient care needs. Advanced search capabilities allow users to find messages by date ranges, participants, keywords, or patient identifiers. The systems maintain indexing that preserves search functionality even as message volumes grow over time.

Storage management features help healthcare organizations balance retention requirements with cost considerations. Tiered storage systems can move older communications to less expensive storage media while maintaining accessibility for audit or legal purposes. Compression and deduplication technologies reduce storage costs without compromising compliance or retrieval capabilities.

Challenges of HIPAA Email Retention?

Storage cost escalation creates ongoing financial pressure as email volumes grow and retention periods extend. Healthcare organizations generate substantial email volumes daily, and retaining communications for years or decades can require significant storage investments. Cloud storage costs continue to increase as data volumes expand, particularly for organizations in states with extended retention requirements.

Data classification complexity arises when determining which email communications require retention under HIPAA versus other regulatory frameworks. Healthcare organizations may need to apply different retention schedules to communications based on content, sender, recipient, and applicable regulations. Manual classification processes become impractical with large email volumes, requiring automated systems that can accurately categorize communications.

System integration challenges emerge when email retention platforms need to work with existing healthcare IT infrastructure. Electronic health record systems, practice management platforms, and communication tools may not integrate seamlessly with retention systems. Data synchronization between platforms can create gaps in retention coverage or duplicate storage requirements.

Compliance monitoring becomes complex when retention policies span multiple regulatory frameworks and state jurisdictions. Healthcare organizations operating across state lines may need to apply the most restrictive retention requirements to ensure compliance in all jurisdictions. Tracking compliance across different retention schedules, legal holds, and disposal requirements requires sophisticated policy management capabilities.

How To Optimize HIPAA Email Retention Strategies

Policy standardization helps healthcare organizations create consistent retention practices across different departments and communication types. Clear guidelines about what communications require retention, how long they must be preserved, and when disposal is appropriate reduce confusion and compliance gaps. Standardized policies also simplify training and help ensure that staff members understand their retention responsibilities.

Technology automation reduces the manual effort required to classify and retain healthcare email communications appropriately. Advanced systems can analyze message content, identify patient information, and apply retention schedules automatically. Machine learning capabilities improve classification accuracy over time while reducing the burden on IT staff and healthcare workers.

Regular policy review ensures that retention practices keep pace with changing regulations and organizational needs. Healthcare organizations examine their retention policies annually to verify compliance with current federal and state requirements. Policy updates may be necessary when organizations expand into new states, add practice specialties, or adopt new communication technologies.

Staff training programs help healthcare workers understand their roles in email retention compliance. Training covers what types of communications require retention, how to handle legal holds, and when to escalate retention questions to compliance teams. Regular refresher training ensures that staff members stay current with policy changes and retention best practices as communication patterns evolve.

HIPAA Compliant Marketing Automation Tools

What are the Infrastructure Requirements For HIPAA Compliant Email?

Healthcare providers, payers, and suppliers increasingly rely on email communication for a wide variety of purposes pertaining to their patients’ and customer’s healthcare journeys. However, ensuring email messaging is both effective and HIPAA compliant requires the right infrastructure, including dedicated environments, high throughput and low latency, end-to-end encryption, scalability and compliance monitoring.

The Health Insurance Portability and Accountability Act’s (HIPAA) regulations mandate a series of data security and privacy requirements to safeguard the electronic protected health information (ePHI) contained in emails, which is a good place to start. At the same time, however, healthcare organizations must also consider deliverability best practices to ensure their messages successfully reach the intended recipients. 

With all this in mind, this post discusses the infrastructure requirements for HIPAA compliant email. We’ll explore the differences between transactional and marketing emails, as well as infrastructure and compliance considerations for each. 

What Are Transactional Emails?

Transactional emails are messages that correspond to a previous interaction between a healthcare organization and an individual. A patient or customer will trigger the delivery of a transactional email by taking a specific action – with the transaction email being confirmation of the action.  

Examples of transactional emails include:

  • Explanation of Benefits
  • Billing statements
  • Invoices
  • Appointment confirmations and reminders
  • Order updates and shipping notifications
  • Password resets and security notifications
  • Plan renewal confirmation 
  • Payment failure notifications
  • In-home care communications

Healthcare companies can also use transactional emails to communicate relevant instructions, next steps, or follow-up actions.

What Are Marketing Emails?

Marketing emails contain content designed to influence the recipient into taking a particular action, usch as ordering a new product or sign up for a new service. Subsequently, they often contain informational materials intended to educate the individual so they can make a more informed decision. 

Examples of marketing emails include:

  • New product or service launches
  • Promotional offers
  • Loyalty reward notifications 
  • Customer reviews and testimonials 
  • Educational materials or campaigns 
  • Preventative care outreach
  • Event Invitations
  • Re-engagement messages (e.g., “We Miss You!..”)

With the proper data safeguards and the effective use of ePHI, marketing emails can be personalized to be made more relevant to the recipient. This then allows patients or customers to be segmented into subgroups according to particular commonalities, e.g., age, gender, lifestyle factors, medical conditions, etc.

Opt-in Rules for HIPAA-Compliant Email Communication 

One significant difference between marketing and transactional emails is that recipients must explicitly opt-in to receive marketing emails. 

HIPAA requires explicit patient consent for marketing emails if they contain ePHI, requiring individuals to opt-in to receive email marketing communications from a healthcare organization. Neglecting to allow people to opt-in to your marketing communications leaves your company open to the consequences of HIPAA non-compliance, which include financial penalties and reputational damage. 

Conversely, healthcare organizations aren’t required to obtain opt-ins to send transactional emails, but these communications are still subject to other HIPAA regulations, such as encryption and audit logging. 

Additionally, marketing emails must comply with the CAN-SPAM Act: US legislation that governs commercial email communication and protects individuals from deceptive sales and marketing practices. The CAN-SPAM Act requires healthcare organizations to provide an opt-out mechanism in the event they no longer wish to receive marketing emails. Subsequently, you must always allow individuals to opt out of marketing emails to stay compliant.

Email Infrastructure Requirements For HIPPA-Compliance

As the vast majority of healthcare organizations need to send marketing and transactional emails, they must have the appropriate infrastructure to facilitate the optimal delivery of both types of emails. Consequently, for HIPAA compliant email, they need to establish the appropriate infrastructure configurations for each, according to their differing purposes, sending patterns, and compliance considerations. 

Let’s look at the infrastructure requirements for each email type in turn, before looking at considerations that pertain to both types of email.

Key Transactional Email Infrastructure Considerations

Transactional emails are sent to a sole patient or customer, with the information therein only intended for that specific individual. Additionally, they can be highly time-sensitive: for example, a password reset or similar emails related to logins and service use must be immediate, while order confirmations need to be delivered ASAP to reassure clients of a company’s reliability and trustworthiness. 

Accounting for this, the infrastructure requirements for transactional emails include: 

  • High Speed and Low Latency: servers that are optimized  for high IOPS (input/output operations per second) and minimal processing delays to ensure near-instant delivery
  • Dedicated IPs: this helps healthcare companies maintain a strong sender reputation to avoid blacklisting, being labelled as spam, etc. This is crucial for reliable, fast delivery. 
  • High Availability and Redundancy: this includes load balancers, failover servers, and geographically distributed data centers to ensure comprehensive disaster recovery and more robust business continuity protocols.  

Key Marketing Email Infrastructure Considerations

In contrast to transactional messages, marketing emails must often be sent out in high volumes, which could be as many as hundreds of thousands or millions per month. As a result, marketing email campaigns have different computational demands, i.e., CPU and storage, than transactional messages intended for a single person. 

Subsequently, the infrastructure requirements for marketing emails include: 

  • High Volume and Scalability: marketing messages require a larger throughput to facilitate the bulk delivery of email. Additionally, servers should scale easily to accommodate increasingly larger campaigns without suffering bottlenecks.
  • Queueing and Throttling: marketing email infrastructure must prevent sending surges that could trigger spam filters or overload recipient servers, which often results in blacklisting. 
  • Dedicated vs. Shared Infrastructure: it’s important to consider whether to opt for private versus shared infrastructure, depending on the size of your organization and the scale of your campaigns. Large senders often use dedicated IPs for better control, while smaller companies or campaigns might use shared pools with strict sender reputation management.

Key Infrastructure Considerations for Both Types of Email

Lastly, there are infrastructure requirements that apply to both types of email that will help facilitate their fast and reliable delivery, respectively. These include:     

  • Separate Infrastructure: consider hosting your transactional and marketing emails on separate servers. This benefits transactional emails in particular, as there are several factors inherent to marketing email campaigns, such as bounced emails and being flagged as spam, that affect an email IP’s reputation. Separate infrastructure maintains the integrity of a healthcare company’s IP address for transactional emails, ensuring they are delivered unimpeded. 
  • Encryption: the ePHI in all email communications must be encrypted in transit, i.e., when sent to individuals, and at rest, i.e., when stored in a database. This helps safeguard the patient data within the message, regardless of its nature. 
  • HIPAA Compliance Monitoring: remaining aware of what ePHI is included in email communications. This keeps data exposure to a minimum and mitigates the unintentional inclusion of patient data in email communications. 
  • Logging and Auditing: this not only allows you to track email activity, but you also can measure the efficacy of your email communications, who accessed ePHI, and what they did with it. This is an essential part of HIPAA compliance and will be subject to tighter regulation when the updates to HIPAA’s Security Rule come into effect in late 2025.

Multi-location organizations face unique challenges coordinating email security across different sites. The top HIPAA compliant email solutions provide centralized management capabilities while accommodating local operational requirements and varying technical infrastructures.

Choosing Between Cloud and On-Premises Options

Cloud-based email solutions offer rapid deployment and reduced internal IT requirements but require careful evaluation of vendor security practices and data location policies. Healthcare organizations must ensure cloud providers offer appropriate business associate agreements and maintain adequate security controls. On-premises solutions provide direct control over email infrastructure and data storage but require significant internal expertise for implementation and maintenance. Organizations choosing this approach must invest in security training, hardware maintenance, and software updates to maintain HIPAA compliance. Cost considerations extend beyond initial implementation expenses to include ongoing maintenance, security updates, and compliance monitoring activities. Cloud solutions offer predictable monthly expenses while on-premises deployments involve variable costs for hardware replacement and staff training.

Evaluating Vendor Capabilities and Track Records

Security certifications provide objective evidence of vendor compliance capabilities and commitment to protecting healthcare data. Organizations should look for certifications like SOC 2 Type II, HITRUST, or ISO 27001 that demonstrate comprehensive security management practices. Client references from similar healthcare organizations help evaluate how well solutions perform in real-world environments. Vendors should provide case studies and references that demonstrate successful HIPAA compliance implementations and ongoing customer satisfaction. Breach history and incident response capabilities reveal how vendors handle security challenges and protect client data. Healthcare organizations should investigate any past security incidents and evaluate vendor transparency and response procedures.

Implementation Planning and Change Management

User training programs must address both technical aspects of new email systems and HIPAA compliance requirements. Healthcare staff need to understand how to use new tools while maintaining proper PHI handling procedures throughout their daily communications. Data migration strategies ensure that existing email archives and contacts transfer securely to new HIPAA compliant email solutions. Organizations must plan for potential downtime and establish backup communication methods during transition periods. Policy updates help align organizational procedures with new email solution capabilities. Entities should review and revise their HIPAA policies to reflect new technical safeguards and user responsibilities for PHI protection.

Measuring Success and Return on Investment

Compliance metrics help organizations track their success in meeting HIPAA requirements and reducing violation risks. Key indicators include user adoption rates, security incident frequency, and audit finding trends that demonstrate improved PHI protection. Operational efficiency improvements often result from implementing modern HIPAA compliant email solutions. Healthcare organizations may experience reduced IT support requirements, faster communication workflows, and improved care coordination capabilities. Risk reduction benefits include lower potential for HIPAA violations, reduced liability exposure, and improved patient trust in organizational privacy practices. These intangible benefits can be impactful but may be difficult to quantify in traditional financial terms.

Future-Proofing Email Security Investments

Technology evolution requires email solutions that can adapt to changing security threats and regulatory requirements. Healthcare organizations should select vendors with strong research and development capabilities and track records of staying current with emerging threats. Scalability considerations ensure that HIPAA compliant email solutions can grow with healthcare organizations and accommodate changing communication needs. Solutions should support increasing user counts, message volumes, and integration requirements without requiring complete replacement. Regulatory changes may affect email compliance requirements over time.

Healthcare Email Marketing Best Practice

Can You Send HIPAA Through Email?

Yes, you can send protected health information (PHI) under HIPAA through email when using appropriate security measures and compliant email systems designed to protect protected health information during electronic transmission. Sending PHI through email requires encryption, access controls, audit logging, and other safeguards that meet regulatory standards for protecting patient information in digital communications. Healthcare providers, payers, and suppliers can transmit protected health information via email when they implement proper security protocols and use compliant email platforms. Understanding how to send HIPAA through email safely helps organizations maintain regulatory compliance while conducting routine business communications and patient care coordination activities.

Security Requirements for Sending HIPAA Through Email

Sending PHI through email requires end-to-end encryption that protects messages and attachments from unauthorized access during transmission and storage. Healthcare organizations cannot use standard email platforms like Gmail, Yahoo, or Outlook for transmitting protected health information without additional security measures. Encryption protocols transform readable text into coded format that only authorized recipients can decrypt and access. uthentication mechanisms verify the identity of both senders and recipients before allowing access to encrypted email content. Digital certificates provide additional verification that messages originated from legitimate healthcare organizations and have not been tampered with during transmission. Secure transmission protocols protect email communications from interception by unauthorized parties during delivery to intended recipients.

Permitted Uses When Sending HIPAA Through Email

Healthcare organizations can send HIPAA through email for treatment, payment, and healthcare operations without obtaining patient authorization. Treatment communications include sharing patient information between healthcare providers involved in care coordination, referrals, and consultation activities. Payment-related emails may include billing information, insurance claims, and financial communications with patients or payers. Healthcare operations encompass quality improvement activities, staff training materials, and administrative communications that support patient care delivery. Patient communications via secure email may include appointment reminders, lab results, and discharge instructions when appropriate safeguards are implemented. For business associate communications, HIPAA through email is permissible when vendors have signed the appropriate agreements and maintain compliant systems.

Prohibited Practices When Sending HIPAA Through Email

Regular email platforms without encryption cannot be used for sending HIPAA through email due to inadequate security protections. Healthcare organizations cannot send protected health information via text message, social media platforms, or other unsecured digital communication channels. Forwarding encrypted emails to non-compliant systems compromises security and violates HIPAA requirements. Sending protected health information to unauthorized recipients constitutes a privacy violation regardless of the security measures used. Healthcare staff cannot use personal email accounts for work-related communications involving patient information. Storing protected health information in unsecured cloud storage systems or sharing login credentials for secure email accounts creates compliance risks and potential security breaches.

Technical Implementation for HIPAA Through Email

Healthcare organizations implementing systems for sending PHI through email need secure email gateways that integrate with existing IT infrastructure. These systems automatically encrypt outgoing messages containing protected health information and provide secure delivery mechanisms for recipients. Message encryption occurs before transmission, ensuring that sensitive content remains protected throughout the delivery process. Recipient verification systems confirm that emails reach intended recipients and prevent unauthorized access to protected health information. Secure message retrieval processes may require recipients to authenticate their identity before accessing encrypted content. Audit logging capabilities track all email activities, including message transmission, recipient access, and any forwarding or reply activities involving protected health information.

Staff Training for HIPAA Through Email Compliance

Healthcare organizations must train staff on proper procedures for sending HIPAA through email and recognizing when additional security measures are needed. Training programs cover identification of protected health information, appropriate use of secure email systems, and policies for handling patient communications. Staff members learn to distinguish between communications that require encryption and those that can use standard email platforms. Policy education includes guidelines for password management, secure login procedures, and incident reporting requirements when security concerns arise. Regular refresher training keeps staff updated on changing regulations and organizational policies for email security. Competency assessments verify that staff members understand their responsibilities when handling protected health information in email communications.

Compliance Monitoring and Risk Management

Healthcare organizations need ongoing monitoring programs to ensure that practices for sending HIPAA through email remain compliant with regulatory requirements. Regular audits review email security configurations, user access controls, and compliance with organizational policies. Risk assessments identify potential vulnerabilities in email systems and communication processes that could lead to privacy violations. Incident response procedures address potential security breaches or unauthorized disclosures involving email communications. Documentation requirements include maintaining records of security training, policy updates, and compliance monitoring activities. Organizations benefit from establishing clear accountability structures and regular review processes that demonstrate ongoing commitment to protecting patient privacy in all email communications involving protected health information.
