New Email Tracking Features Deliver More Accurate Engagement Insights

LuxSci Email Tracking Features

Today, we’re excited to announce two new reporting features designed to help healthcare organizations improve reporting accuracy and the overall effectiveness of their email campaigns. The new features offer deeper insights into Apple Mail and Google email performance by distinguishing between opens and clicks performed by human actions and automated events — and by giving users control over how these events are reflected in LuxSci email campaign reporting.

Let’s dive into what these features are and how they can help you get more precise data from your healthcare email marketing and communications efforts.

Feature 1: Enhanced Open and Click Tracking – Human vs. Automated

One of the biggest challenges in email tracking today is the rise of automated systems that pre-load images and scan links in emails. Automated systems can trigger open or click events without the recipient actually interacting with the email, leading to inflated and misleading open/click rates.

With LuxSci’s new enhanced open and click tracking, you can now tell whether Apple Mail and Google emails (Gmail and Google Workspace) were opened or a link was clicked by a human or by an automated system. This crucial distinction allows you to have a much clearer picture of actual user engagement.

Here’s how it works:

  • When emails are sent with open tracking enabled, a small tracking image (also known as a pixel) is embedded in the email. When that image is loaded, the system tracks the email as “opened.”
  • Similarly, links in the email are encoded to track clicks. If a recipient clicks a link, it triggers a “clicked” event, but these events can also be triggered by automated systems.
  • LuxSci’s enhanced open and click tracking feature analyzes these events and reports whether the actions were performed by a human or an automated system, helping you sift through false positives.

Feature 2: Suppressing Automated Events in Your Reporting

In addition to tracking the source of open and click events, LuxSci’s second new feature gives you the option to exclude automated events from Apple Mail and Google email from your email engagement statistics altogether. This setting, available in account-wide outbound email settings, is a powerful tool for ensuring the accuracy of your reports and understanding true user engagement.

Here’s how it works:

  • Automated opens and clicks can be removed from email reporting for better accuracy. For example, if a security bot clicks a link, that event will be logged, but it won’t mark the email as “clicked” in your statistics.
  • Your open, click, and click-through rates can be set to only reflect real human actions, making these metrics much more reliable for evaluating campaign performance and actual patient engagement.

Why These Features Matter for Healthcare Email Marketing

For healthcare organizations, reliable metrics are essential. Emails often carry critical information related to patient care, transactions, or marketing, and understanding who is engaging with your content is critical to ongoing improvement and long-term success. At the same time, automated actions can inflate your open and click rates, leading to inaccurate conclusions about your email performance.

LuxSci’s new features give you the power to:

  • Track email engagement with precision: Know the difference between human engagement and automated actions, so your metrics reflect reality.
  • Customize your reporting: Decide whether you want to include or suppress automated events in your reports.
  • Improve deliverability strategies: By analyzing which emails are genuinely opened or clicked by real people, you can fine-tune your email campaigns to maximize their effectiveness.

Ready to Enhance Your Email Tracking?

Take control of your email deliverability insights with LuxSci’s newest email tracking tools. Whether you want to gain deeper insights into recipient behavior or eliminate noise from automated systems, these features are designed to help you improve your email reporting, performance and engagement.

HIPAA Compliant Email

Rethinking HIPAA Compliant Email – Not Just a Checkbox

The compliance-only mentality is outdated.

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

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

What Makes Email Truly HIPAA Compliant?

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

  • Use encryption at all times
  • Be access-controlled
  • Include audit logs
  • Be stored and transmitted in a secure manner
  • Provide a Business Associate Agreement

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

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

The Real Opportunity – Secure, Personalized Email with PHI

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

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

Breaking the One-Size-Fits-All Approach in Healthcare Email

  • Improving Health Plan Enrollments – Targeted email outreach during open enrollment, tailored by eligibility or plan type, and powered by automated workflows leads to higher enrollments and lower call center costs.
  • Driving Awareness and Sales of New Services or Products – Have a product upgrade offer, new wellness program or telehealth service? Send secure, PHI-informed HIPAA compliant email to the right audience for increased sales and faster adoption.
  • Optimize Explanation of Benefits NoticesReplace snail mail with email that’s fast, reliable and trackable, ensuring customers are informed and compliance is met.

The Healthcare Marketer’s Secret Weapon: Using PHI Responsibly

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

Meeting the Personalization Demands of Today’s Patients and Customers

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

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

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

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

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

HIPAA Compliance and Email Communications

How Does HIPAA Compliance and Email Communications Work?

HIPAA compliance and email communications require healthcare organizations to implement administrative, physical, and operational safeguards that protect patient information during electronic transmission and storage. Federal regulations mandate encryption protocols, access controls, audit logging, and business associate agreements for all email systems handling protected health information. Healthcare providers must balance security requirements with operational efficiency, ensuring that email communications enhance patient care without creating compliance vulnerabilities or exposing organizations to regulatory penalties.

Safeguards for Email Security

Policy development establishes the framework for how healthcare organizations handle patient information through email channels. Written policies must specify who can send patient data via email, what types of information are appropriate for electronic transmission, and what approval processes govern sensitive communications. Documentation requirements ensure that policies reflect current regulatory standards and organizational practices.

Training programs prepare healthcare staff to use email systems securely while maintaining patient privacy throughout all communications. Education should cover encryption activation procedures, recipient verification methods, and content appropriateness criteria that prevent inadvertent disclosures. New employee training timelines ensure staff understand email security requirements before accessing patient information systems.

Access management procedures control which staff members can use email systems to communicate about patients and what information they can access. Permission structures should align with job functions, ensuring that billing staff, clinical providers, and administrative personnel each have appropriate access levels. Regular access reviews identify outdated permissions that should be revoked when staff change roles or leave organizations.

Security incident procedures outline how organizations respond when email security breaches occur or when staff discover potential vulnerabilities. Response protocols should include immediate containment steps, breach scope assessment methods, and notification procedures for affected patients and regulatory authorities. Documented incident handling demonstrates organizational preparedness during compliance audits.

Encryption Standards That Meet Regulatory Requirements

Transport-level encryption protects email messages during transmission between servers, creating secure channels that prevent interception while communications travel across public networks. TLS 1.2 or higher protocols establish encrypted connections that meet current security standards for protecting healthcare data. Server certificates verify the identity of receiving systems before allowing message transmission to prevent misdirected communications.

Message-level encryption converts email content into unreadable code before transmission, ensuring that only intended recipients with proper decryption keys can access patient information. AES 256-bit encryption provides strong protection that satisfies regulatory expectations for securing electronic protected health information. Automatic encryption removes reliance on manual activation that busy healthcare staff might forget during patient care activities.

Storage encryption protects archived email communications containing patient information while messages reside on servers or backup systems. Encryption at rest prevents unauthorized access if physical storage devices are stolen or improperly disposed. Key management protocols ensure that encryption keys receive the same protection as the data they secure.

Digital signatures add authentication layers that verify message origin and detect any unauthorized modifications during transmission. Certificate-based systems confirm sender identity before allowing message delivery, reducing risks that fraudulent communications might compromise patient information. HIPAA compliance and email communications depend on multiple encryption layers working together to protect data throughout its lifecycle.

Access Controls and Authentication Mechanisms

Multi-factor authentication strengthens account security by requiring users to provide multiple forms of identification before accessing email systems containing patient data. Passwords combined with mobile verification codes, biometric scans, or hardware tokens create barriers that prevent unauthorized access even when credentials are compromised. Authentication strength should match the sensitivity of patient information accessible through email systems.

User provisioning processes establish email accounts for new staff members while defining their access permissions based on job functions and patient care relationships. Automated provisioning systems integrated with human resources databases ensure that access aligns with employment status and role requirements. Termination procedures immediately revoke access when employment ends to prevent former staff from accessing patient communications.

Session controls automatically log users out after inactivity periods, preventing unauthorized access from unattended workstations in busy healthcare environments. Timeout durations should balance security needs with operational efficiency, allowing sufficient time for thoughtful message composition without creating excessive vulnerability windows. Concurrent session monitoring detects unusual login patterns that might indicate account compromise.

Audit capabilities track all email system activities including message transmission, viewing, forwarding, and deletion actions performed by users. Comprehensive logs capture timestamps, user identities, and specific actions taken with patient information. Log retention periods should meet regulatory requirements while supporting security investigations and compliance demonstrations.

BAA Requirements

Contractual obligations between healthcare organizations and email service providers establish responsibilities for protecting patient information during transmission and storage. Written agreements must address encryption standards, security incident notification timelines, and data handling procedures when business relationships terminate. Liability provisions allocate financial responsibilities when breaches result from provider negligence or system failures.

Vendor security assessments verify that email providers maintain appropriate safeguards before organizations entrust them with patient communications. Evaluation procedures should examine provider certifications, data center security, and incident response capabilities. Due diligence documentation demonstrates that organizations selected vendors carefully rather than accepting inadequate security measures.

Performance monitoring ensures that providers maintain contracted security standards throughout business relationships. Regular audit report reviews, security assessment updates, and compliance certification renewals verify ongoing provider commitment to protecting healthcare information. Performance issues should trigger immediate corrective action discussions to prevent security degradation.

Subcontractor management addresses situations where email providers use third-party services for hosting, backup, or support functions. Agreements should require providers to obtain equivalent security commitments from subcontractors who might access patient information. Healthcare organizations need visibility into the complete chain of entities handling their patient communications.

Documentation and Compliance Evidence

Security configuration documentation records the specific settings that organizations implement to protect email communications containing patient information. Configuration records should detail encryption algorithms, authentication requirements, access control structures, and audit logging parameters. Documentation updates track changes over time, creating histories that support compliance demonstrations.

Training records demonstrate that organizations educate staff about secure email practices and HIPAA compliance and email communications requirements. Documentation should include training dates, participant names, content covered, and assessment results verifying comprehension. Record retention periods should extend beyond individual employment to support long-term compliance evidence.

Risk assessment documentation identifies vulnerabilities in email systems and describes mitigation measures implemented to reduce security threats. Assessment reports should evaluate encryption strength, access control effectiveness, and potential failure points that could compromise patient information. Annual assessment updates track how organizations adapt security measures as threats evolve.

Incident reports document security breaches involving email communications and describe organizational responses to contain damage and prevent recurrence. Detailed breach records should include discovery methods, scope determinations, notification procedures, and corrective actions implemented. Incident documentation provides evidence of appropriate breach handling during regulatory investigations.

Operational Considerations and Best Practices

Content appropriateness guidelines help staff determine which patient information is suitable for email transmission versus what requires more secure communication methods. Routine appointment confirmations and general health education may be appropriate for encrypted email while complex diagnoses warrant telephone or in-person discussions. Emergency communications should never rely solely on email that patients might not check promptly.

Recipient verification procedures ensure staff confirm email addresses before transmitting patient information to prevent misdirected communications. Double-check processes, automated address validation, and recent communication history reviews reduce human errors that could expose patient data. Organizations should implement technological controls that flag external recipients when sending patient information.

Mobile device management addresses security challenges when staff access email from smartphones and tablets outside secure healthcare facilities. Device encryption, remote wipe capabilities, and containerization technologies separate work communications from personal data on employee devices. Bring-your-own-device policies must ensure that personal devices meet organizational security standards before allowing patient information access.

Retention management balances regulatory requirements to preserve email communications with operational needs to manage storage capacity efficiently. Automated retention policies should archive messages for required periods while deleting expired communications to minimize data exposure risks. Legal hold procedures must override automated deletion when litigation or investigations require communication preservation.

Understanding HIPAA compliance and email communications enables healthcare organizations to leverage digital communication benefits while protecting patient privacy and avoiding regulatory penalties that could result from security failures or policy violations.

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:

  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

Received: from dispatch1-us1.ppe-hosted.com (dispatch1-us1.ppe-hosted.com [2.2.2.2])

	(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>);

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 Email Rules

HIPAA Email Rules: What You Need to Know

The Health Insurance Portability and Accountability Act (HIPAA) is a complicated law that defines the standards for the secure collection, transmission, and storage of protected health information (PHI). When information is stored or exchanged electronically, the HIPAA Security and Privacy Rules require covered entities, i.e., organizations that handle PHI, to safeguard its integrity and confidentiality.

One of the most common ways that PHI is shared electronically is via email, so understanding HIPAA email rules is essential for achieving compliance and protecting sensitive data.

The HIPAA Email Security Rule

It’s important to note that HIPAA does not require the use of any specific technology or vendor to meet its requirements. Generally speaking, the Security Rule requirements for email fall into four categories:

  1. Organizational requirements state the specific functions a covered entity must perform, including implementing policies, procedures and obligations concerning business associate agreements (BAAs).
  2. Administrative requirements relate to employee training, professional development, and management of PHI.
  3. Physical safeguards encompass the security of computer systems, servers, and networks, access to the facility and workstations, data backup and storage, and the destruction of obsolete data and HIPAA email archiving.
  4. Technical safeguards ensure the security of email data transmitted over an open electronic network and the storage of that data.

Let’s move on to discussing some of the main requirements that apply to email and the steps you need to take to secure email accounts that transmit and store PHI.

HIPAA Email Rules: Compliance Checklist

While encryption gets most of the spotlight during discussions on email security, the HIPAA email rules, in contrast, cover a range of behaviors, controls, and services that work together to address eight key areas:

  1. Access
  2. Encryption
  3. Backups and Archival
  4. Defense
  5. Authorization
  6. Reporting
  7. Reviews and Policies
  8. Vendor Management

Let’s look at each aspect of HIPPA’s email rules in greater detail.

1. Access

Access controls help safeguard access to your email accounts and messages. Implementing access controls is essential to keep out unauthorized users and secure your data, with key steps including:

  • Using strong passwords that cannot be easily guessed or memorized – and changing them frequently, e.g. every 30 days.
  • Creating different passwords for different sites and applications.
  • Enabling multi-factor authentication (MFA).
  • Securing connections to your email service provider using TLS and a VPN.
  • Blocking unencrypted connections.
  • Pre-emptively installing software that remotely wipes sensitive email off your mobile device when it is stolen or misplaced.
  • Logging off from your system when it is not in use and when employees are away from workstations.
  • Emphasizing opt-out email encryption to minimize breaches resulting from human error.

2. Encryption

Email is inherently insecure and at risk of being read, stolen, intercepted, modified, and forged (repudiated). Covered entities should go beyond the technical safeguards of the HIPAA Security Rule and take steps that exceed what is required to futureproof their communications. Email encryption features to adopt include the following:

  • The ability to send secure messages to anyone with any email address.
  • The ability to receive secure messages from anyone.
  • Implementing measures to prevent the insecure transmission of sensitive data via email.
  • Exploring message retraction features to retrieve email messages sent to the wrong address.
  • Avoiding opt-in encryption to satisfy HIPAA Omnibus Rule.

3. Backups and Archival

HIPAA email rules require copies of messages containing PHI to be retained for at least six years. In light of this, organizations must consider the following:

  • How are email folders backed up?
  • Are there at least two different backups at two different geographical locations? Additionally, the processes updating these backups should be independent of each other as a measure against backup system failures.
  • Have you maintained separate, permanent, and searchable archives? While the emails should be tamper-proof, with no way to delete or edit them, they should be easily retrievable to facilitate discovery, comply with audit requests, and support business-critical scenarios.

4. Defense

Cyber threats against healthcare organizations are continually on the increase. Some may be surprised to learn that HIPAA compliant email rules mandate that organizations take steps to defend against possible malicious actors. With this in mind, consider implementing the following technologies:

  • Server-side inbound email malware and anti-virus scanning to detect phishing messages and malicious links.
  • Showing the sender’s email address by default on received messages.
  • Email filtering software to detect fraudulent messages and ensure it uses Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting and Conformance (DMARC) information to classify messages.
  • Scanning outbound email.
  • Scanning workstations for malware, i.e., viruses, ransomware, etc.
  • Using plain text previews of your messages.

5. Authorization

A critical aspect of HIPAA’s email rules is ensuring that cybercriminals cannot impersonate your company or employees. Configuring your domains with SPF and DKIM is essential to verify your identity as an authorized sender of mail from your domains. Also, ensure that users cannot send messages through your email servers without authentication and encryption.

6. Reporting

Setting accountability standards for email security is essential to establishing and strengthening your HIPAA compliance posture. Important steps to take include:

  • Creating login audit trails.
  • Receiving login failure and success alerts.
  • Auto-blocking known attackers.
  • Maintaining a log of all sent messages.

7. Reviews and Policies

Humans are the greatest vulnerability to any security and compliance plan, so creating policies and procedures that focus on plugging vulnerabilities and preventing human errors is essential. Strategies for reducing risk include:

  • Inviting independent third parties to review your email policies and user settings. Fresh, unbiased eyes can discover existing issues quickly.
  • Preventing devices that connect to sensitive email accounts from connecting to public WiFi networks.
  • Creating email policies prohibiting users from clicking on links or opening attachments that are not expected or requested.

8. Vendor Management

Most companies do not manage their email in-house, so it’s crucial to thoroughly research and vet whoever will be responsible for your email services. Perform an annual review of your email security and stay on top of emerging cybersecurity threats to take proactive action and for continued compliance with HIPAA email rules.
