As the healthcare industry moves toward delivering more efficient, value-driven care, the effective use of patient data, including Protected Health Information (PHI), to personalize communications is an essential component of data-driven care: strategies for improving engagement, fostering trust, and promoting healthier patient outcomes.

However, using PHI in email and communications to facilitate data-driven care requires careful attention to implementing the appropriate security measures required to safeguard sensitive patient data and satisfy HIPAA compliance requirements.

In this article, we detail how healthcare providers, payers, and suppliers can securely use PHI to tailor email messages and improve patient relationships using a data-driven approach, delivering greater efficiency and a greater experience for all.

What is data-driven care?

Data-driven care involves the use of patient data, analytics, and, in recent years, AI-driven insights to improve decision-making, personalize treatments, and improve health outcomes for patients.

In the past patient care was driven by clinical experience, generalized treatment protocols, and, the comparatively limited data kept on paper records. Naturally, despite healthcare professionals doing their best, this approach had several limitations. Clinical experience can easily be defied by unique health circumstances. Patients may not respond to general treatment plans, and paper records are prone to loss, damage, and human error, as well as being often slow and/or complicated to transfer.

Fortunately, the digitization of patient data (transforming it from PHI to ePHI (electronic protected health information) marked the advent of data-driven care. With patient data stored in Electronic Health Record (EHR) systems, customer data platforms (CDP), and revenue cycle management platforms (RCM), it became easier for healthcare organizations to store, update and, most importantly, back up and share patient data.

Additionally, advanced analytics has made it easier for healthcare companies to offer more effective proactive outreach and engagement, based on pertinent data points, as opposed to merely reacting to symptoms that a patient may display over time.

Better still, technological advancements have shown that we’re just scratching the service when it comes to the advancement and potential of data-driven care. For example, AI models are becoming increasingly effective at designing personalized treatment plans for patients: using the ePHI collected by their healthcare providers.

As these digital solutions grow in sophistication and dependability, they’ll be able to consistently assist healthcare professionals in treating, engaging and marketing to patients effectively. Should these technologies reach their potential, patients will better respond to their personalized treatment plans, and healthcare providers will be able to treat more patients in less time – and a greater number of people will enjoy positive health outcomes and a better quality of life.

What Are the Benefits of Data-Driven Care?

Better Decision-Making: the more information a healthcare professional any segment of the industry has at their disposal, the better their ability to make decisions about potential treatment options, education and communications, and ongoing care.
Personalized Treatment Plans: using patient history, genetics, and lifestyle data, applications can tailor treatments to an individual’s state of health.
Early Disease Detection: predictive analytics help identify health risks before symptoms appear, increasing the chances of a condition being caught early and becoming more detrimental to the patient’s health
Operational Efficiency: better decision-making saves time, preserves scarce resources, and helps ensure healthcare practitioners are employed to their full capabilities.
Better Patient Engagement: data-driven insights promote proactive patient communication, such as appointment reminders, annual check-up or test reminders, and preventative care advice.

How Does Data-Driven Care Relate to HIPAA Compliance?

Data-driven care depends on collecting, storing, and sharing sensitive patient data, which must comply with HIPAA’s Privacy and Security Rules, both of which are designed to ensure that the proper safeguards are put in place to secure ePHI. With this in mind, key compliance concerns surrounding data-driven care include:

Data Security: ensuring end-to-send PHI encryption in transit and at rest.
Access Controls: limiting PHI access to authorized personnel only, i.e., those who have reason to access it as part of their jobs.
Third-Party Risk Management: ensuring you have Business Associate Agreements (BAAs) in place with any third parties with access to the PHI under your care, e.g., email platforms, equipment suppliers, online pharmacists, etc.
Audit Trails & Compliance Reporting: tracking who accesses patient data and how it’s used. Additionally, retaining copies of these logs for extended periods as per differing compliance regulations (e.g., retaining them for six years as per HIPAA regulations).

What Types of PHI Can Be Used in Email Communications?

When it comes to using PHI for personalized emails, healthcare organizations need to be clear about what information can be included. PHI can encompass a wide range of data, including:

Personal Identifiers: these identifiers include a patient’s name, address, contact details, Social Security number, and other personal information. On their own, they may not necessarily count as PHI, but when medical-related data, it must be secured as per HIPAA regulations.
Medical History: conditions, diagnoses, treatment plans, lab results, and medications.
Clinical Data: this includes test results, imaging reports, medical procedures, surgical history, and appointment information.
Treatment Information: recommendations for medications, treatments, and care plans, which can be personalized based on the patient’s health needs and the PHI held by their healthcare providers.
Insurance and Billing Information: Information related to insurance coverage, claims, and billing.

These valuable data insights of PHI can be included in email communications to craft relevant, tailored content that resonates with the patient or customer, but only of you’re email is HIPAA compliant.

For example, a healthcare provider might send an email about a new medication to a patient who has been recently diagnosed with a specific condition. Similarly, an insurance provider could send a tailored wellness program and preventative care tips based on the patient’s health data.

Benefits of Using PHI for Personalized Patient Engagement

When used effectively, and, above all, securely, personalized communication based on the intelligent use of PHI can lead to numerous benefits for healthcare providers, payers, and suppliers, which include, but aren’t limited to:

Improved Engagement: patients and customers are more likely to open and engage with email communications that are relevant to their health needs and concerns. Personalized email messaging that uses PHI, including treatment suggestions, appointment reminders, or wellness tips, increases the likelihood of the recipient engaging with the message.
Timely and Relevant Information: Sending timely messages, like reminders for health screenings, prescription refills, or post-operative care, keeps patients engaged with their care plan, ensures better adherence to prescribed medical advice, and takes a more active role in their overall healthcare journey. This is particularly important for chronic disease management, where proactive communication can help prevent complications and reduce hospital readmissions.
Better Relationships with Payers and Suppliers: healthcare payers and suppliers can also leverage PHI for personalized communications. For example, insurers can send targeted messages about new health plan options, plan renewals, claims processes, or wellness programs tailored to the patient’s health needs. Suppliers, meanwhile, can use data to communicate directly with patients about new product offerings, adherence tools, or therapies based on their present state of health. This personalized engagement can enhance customer satisfaction and loyalty.
Stronger Brand Loyalty: all combined, consistently engaging with patients and customers about topics related to their health needs and concerns – subjects, in some cases, they may not be discussing with anyone else – helps them develop trust in their healthcare providers. This, subsequently, makes them more receptive to future email communications, resulting in better adherence to treatment plans, better healthcare outcomes, and higher levels of satisfaction with their healthcare provision.

Ensuring HIPAA-Compliant Data-Driven Care

Before any PHI is included in email communications, healthcare organizations must follow proper security protocols to ensure HIPAA compliance. Here are some of the most fundamental ways to ensure HIPAA compliance when implementing data-driven care practices.

1. Patient Consent

First and foremost, healthcare organizations must obtain explicit consent from patients before sending their PHI via email. HIPAA compliant email marketing requires that all recipients opt-in before receiving emails. Patients should be informed about the types of communications they will receive and should have the option to opt in or opt out of receiving different types of communications containing PHI.

2. Encryption

Encrypting email communications is essential to protecting PHI. Email encryption ensures that the message is unreadable to a malicious actor if it’s intercepted during transmission. Any email that contains PHI must be encrypted end-to-end, i.e., in transit and at rest, which includes both the message content and any attachments. It’s also important that the email service being used is fully HIPAA-compliant, meaning it must have the technical safeguards required under its stringent regulations.

3. Secure Email Solutions

HIPAA compliant email platforms, such as LuxSci, offer built-in, automated encryption, authentication, and access controls to safeguard patient data. These solutions ensure that PHI is only accessible to authorized individuals and that the integrity and privacy of the data are maintained.

4. Access Control and Authentication

To protect PHI, email systems must be configured with strict access control measures. This includes setting up multi-factor authentication (MFA) for accessing email accounts or documents that contain sensitive data. MFA adds an additional layer of security, ensuring that even if a password is compromised, the account cannot be accessed without additional verification methods, e.g., a security access token, or biometric scan.

5. Data Minimization

When sending PHI via email, it’s important to limit the amount of information shared to what is necessary for the communication. For instance, while treatment instructions may be relevant, healthcare organizations must avoid sharing overly detailed medical histories or unnecessary personal identifiers when it’s outside the scope of the communication, or the topic being discussed.

By the same token, data minimization must also apply to access control privileges, ensuring that those who handle PHI only have access to the patient data they require for their job role.

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

November 18, 2025
Pete Wermter

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.

What Does b2b Medical Marketing Help Healthcare Vendors Accomplish?

November 4, 2025
Erik Kangas

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.

How Insurers Can Save Millions Per Month with Secure Email EOBs

June 10, 2025
Pete Wermter

Have you looked into what it’s costing your company to snail mail EOBs these days?

EOBs give an individual an increased understanding of their insurance coverage, the cost of care, and their out of pocket expenses. As a result, it’s absolutely critical that health insurers deliver EOBs quickly and effectively.

However, the most commonly used method for sending out EOBs, traditional mail or snail mail, has several drawbacks that can prevent important information about healthcare coverage from reaching people in a timely manner – not to mention the high cost insurers take on to send them. This can leave policyholders in the dark about their healthcare coverage, which can lead to confusion and dissatisfaction with their insurance provider when they receive an unexpected medical bill.

Furthermore, because EOBs contain the protected health information (PHI) of policyholders or members, insurers are bound by HIPAA (the Health Insurance Portability and Accountability Act) regulations to ensure their secure delivery. Consequently, the risks inherent to sending paper EOB statements in the mail not only have security implications but also potential consequences for non-compliance.

With all this in mind, this post discusses why healthcare insurers should send EOBs to their policyholders via secure email instead of traditional mail. We detail the various benefits of making the switch to email EOBs, which include enhanced security, better adherence to compliance regulations, higher deliverability rates, and significant cost savings.

Security Benefits

Insurance companies that send out EOBs via email as opposed to traditional mail are less likely to be at risk for a data breach or leak of PHI. Firstly, sending an EOB via email drastically decreases the risk of interception. When sent in paper form, an EOB could be:

Lost, stolen or damaged in transit
Delivered to the wrong address
Not properly deposited in a letter or mailbox, then stolen
Intercepted within the intended address by another individual who lives at or has access to the residence.

Conversely, as detailed later in this post, email allows for various controls and processes, which mitigate the risks of unsuccessful message delivery.

Additionally, secure, HIPAA compliant email provides data encryption, which safeguards the sensitive patient data within EOBs during transmission and at rest by rendering it unreadable to malicious actors who might intercept it or gain access to it. Physical mail, in contrast, offers no such protection, as someone who intercepts a paper EOB notice can simply open it and freely read its contents.

Finally, secure email delivery platforms, such as LuxSci, feature identity verification and access controls that enable healthcare insurers to restrict access to PHI, limiting its exposure. Similarly, HIPAA compliant email also provides auditing logging capabilities to track access to patient data, to quickly identify the source of security breaches.

Increased Delivery

Once a person opts-in, sending an EOB by email greatly increases its deliverability, up to 98% or more – almost instantly. By better ensuring a policyholder receives their EOBs, healthcare insurers increase the chance of successfully communicating the intended information they contain, namely, the cost of a service and how much they’re required to cover.

Additionally, the ability to track secure email in near real-time also enhances its deliverability, as it allows organizations to determine the cause of delivery failure and make subsequent attempts to get the EOB delivered. At the same time, the process of determining the reason for the message failure may also reveal security concerns; a process that is very difficult, if not impossible, to achieve with traditional physical mail.

Radical Cost Savings

Simply put, sending EOBs via email instead of traditional mail can save health insurers massive amounts of money. By saving a dollar or more per EOB, the cost savings can quickly add up to millions of dollars per month in savings.

If you’re curious about just how much you can save with email EOBs, try our just-released email EOB ROI calculator. You can see how much your company can save with just a 30 percent shift from physical mail EOBs to email, in a few seconds.

Try the EOB Calculator here

The most significant cost reduction is the money saved on printing and mailing paper EOB statements. Additionally, the cost of administering the delivery of EOB notices is lowered when it’s done electronically. Resending EOBs in the event of their non-delivery also is much easier, faster and cheaper via email.

Compliance Benefits

Because sending an EOB via email requires HIPAA compliance, your communications are encrypted by default, protecting patient privacy and keeping PHI out of the hands of malicious actors, all while reducing the risk of HIPAA compliance violations. The security features built into HIPAA compliant email platforms, such as encryption, access control, and audit logs, help insurers satisfy the requirements of HIPAA’s Privacy and Security Rules in their compliance efforts.

Another considerable benefit of using secure email to send policyholders their EoBs, or, in fact, any communication containing PHI, is that it’s far easier to implement breach notification protocols. HIPAA compliant email delivery platforms provide real-time tracking, so companies can pinpoint email message failures quickly and act accordingly. Similarly, intrusion detection systems and other cybersecurity measures that support email systems enable the faster detection and containment of data breaches.

In stark contrast, physical mail is far more difficult to track. Consequently, security breaches via mail could go unnoticed for days or even weeks. If you’re unaware of a data breach, let alone have not yet contained or mitigated it, you’re unable to inform all affected parties, resulting in further HIPAA violations and a loss of customer trust.

Reduced Carbon Footprint

It’s difficult to highlight the cost benefits of sending EOBs to policyholders by email without recognizing the positive environmental impact, too. Email EOBs cuts down on paper usage, for both the notices themselves and the envelopes they’re mailed in. Then there’s the matter of the electricity and ink involved in printing them, the emissions produced in their delivery, etc. Opting to send EOBs via email reduces all these factors, which enables healthcare organizations to lower their carbon footprint and, where applicable, meet their sustainability obligations.

Now’s the Time to Move to Email EOBs

LuxSci’s HIPAA compliant Secure High Volume Email solution enables healthcare insurers to instantly send EOBs to policyholders securely and at scale, extending into hundreds of thousands and millions of messages a month.

Our HIPAA compliant email delivery platform features:

Dedicated IPs that isolate critical transactional messages, such as EOBs, from other email traffic, allowing our clients to reach deliverability rates of 98% or more.
Real-time tracking for determining the delivery status of EOBs, as well as troubleshooting unsuccessful delivery attempts.
Flexible encryption through LuxSci’s proprietary SecureLine Technology, which automatically adjusts encryption according to the recipient to better ensure the protection of sensitive data, including for EOBs or any sensitive healthcare communication.

Understanding HIPAA Email Retention Requirements

May 22, 2025
Erik Kangas

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.

How To Send HIPAA Compliant Emails

January 6, 2025
Erik Kangas

Knowing how to send HIPAA Compliant Emails is a critical requirement for healthcare providers, payers and suppliers dealing with protected health information (PHI). With fines reaching into the millions, non-compliance isn’t something you want to risk when engaging with our customers and prospects. Unfortunately, many organizations fall into the trap of believing they’re sending HIPAA compliant email because they’ve applied what we call “self-certification” strategies—without fully understanding what’s required to be compliant.

Are you 100% sure that you’re sending HIPAA compliant emails and understand HIPAA email rules?

In this blog post, we’ll delve into the risks of being non-compliant, explain why self-certification strategies often lead to problems, and provide a HIPAA-compliant email checklist to help ensure your organization avoids the pitfalls self-compliance.

The Importance of Sending HIPAA Compliant Emails

HIPAA (Health Insurance Portability and Accountability Act) was established to ensure the protection and privacy of patients’ PHI. This law mandates that any entity handling PHI must implement strict safeguards to prevent unauthorized access, breaches, and exposure of sensitive patient data.

In today’s digital world, where healthcare communications often take place over email and other digital platforms, maintaining HIPAA compliance becomes even more complex. It’s not enough to merely think you’re compliant; you must be able to prove it beyond a doubt.

What Is PHI and Why Does It Need to Be Protected?

As a quick reminder, PHI refers to any data that can be used to identify an individual and that relates to their past, present, or future health condition. This can include anything from personal identification info to medical records and billing information to email exchanges that reference patient care.

Examples of PHI include:

Names
Addresses
Birth dates
Social Security numbers
Medical history and diagnoses
Treatment plans & prescriptions
Medical device usage and services
Appointment information
Billing, payments and insurance information

The Risks of Not Being 100% Sure About HIPAA Compliance

In addition to losing sleep at night, the consequences of sending non-compliant emails can be significant. Non-compliance can result in hefty penalties, ranging from $100 to $50,000 per violation, depending on the severity and intent. In some cases, these fines can even surpass $1.5 million annually.

But it’s not just the fines—PHI exposure opens the door to a variety of serious risks, including the reputational damage that can stem from breaches of patient data that can impact peoples’ lives and the future of your business. Patients place immense trust in healthcare providers and organizations to safeguard their sensitive information, which stretches beyond HIPAA-compliance to overall data security and privacy. The loss of patient trust is difficult—if not impossible—to regain once compromised.

The Problem with DIY HIPAA Compliance

Simply put, self-certifying HIPAA compliance is a recipe for disaster. Many companies and healthcare organizations falsely believe that if they conduct an internal review or have implemented basic security measures, they’re fully compliant. But without the right expertise and the right HIPAA compliant infrastructure in place, especially encryption, it’s easy to overlook details.

Even if you have encryption in place or think your emails are safe, these minimal steps can create a false sense of security. True HIPAA compliance requires continuous monitoring, updating of policies, and regular training to address potential risks.

A Checklist for Sending HIPAA Compliant Email

Sending HIPAA compliant email means ensuring you’ve implemented the following safeguards:

1. Encryption Standards for HIPAA Compliance

All emails containing PHI must be encrypted both at rest and in transit—end-to-end. Ensure your email service provider offers high-grade encryption protocols, like TLS (Transport Layer Security), for sending and receiving messages, and flexible options, including dedicated cloud infrastuctures for the highest levels of data protection.

2. Secure Access and Authentication

Set up multi-factor authentication (MFA) and role-based access controls to limit who can access emails containing PHI.

3. Business Associate Agreements (BAA)

If you’re using a third-party email provider, you must have a signed BAA. This agreement ensures that the provider will uphold HIPAA’s security standards.

4. Data Backup and Recovery

Make sure your email system has a secure backup and recovery solution. Data breaches can happen, but having a recovery plan will minimize damage and maintain compliance.

5. Employee Training and Awareness

Ensure your employees are regularly trained on HIPAA guidelines. Human error is a leading causes of HIPAA violations, so proper education is key.

6. Regularly Audit Your HIPAA Compliance Strategy & Practices

HIPAA regulations evolve as technology advances. Conducting regular compliance audits ensures your security protocols are up to date with the latest best practices.

7. Avoiding Overconfidence in Your Own Processes

No matter how confident you are in your HIPAA strategy, bringing in an external auditor can provide an unbiased view of your compliance status and help identify overlooked vulnerabilities.

Don’t Let HIPAA Self-Certification Fool You!

HIPAA compliance is not something you can afford to be unsure about. The risks—both financially and reputationally—are too great. While it may be tempting to “self-certify” or assume your current measures are sufficient, doing so can leave your organization—and your patients and customers—vulnerable. Instead, ensure that you follow a comprehensive strategy that includes best-in-class email encryption, secure access, regular audits, employee training, and support from external experts.

Don’t take shortcuts when it comes to protecting sensitive health information and ensuring HIPAA compliance—get it right from the start.

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

January 9, 2024
LuxSci

SMTP TLS encryption is popular because it provides adequate data protection without creating a complicated user experience for email recipients. Sometimes, though, the experience is too seamless, and recipients may wonder if the message was protected at all.

Luckily, there is a way to tell if an email was encrypted using TLS. To see if a message was sent securely, we can look at the raw headers of the email. However, it requires some knowledge and experience to understand the text. It is actually easier to tell if a recipient’s server supports TLS than to tell if a particular message was securely transmitted.

To analyze a message for transmission security, we will look at an example email message sent from Hotmail to LuxSci. We will explain what to look for when decoding the message headers and how to tell if the email was transmitted using TLS encryption.

An Example Email Message

First, we must understand how an email message typically travels through several machines on its way from the sender to the recipient. Roughly speaking:

The sender’s computer talks to the sender’s email or WebMail server to upload the message.
The sender’s email or WebMail server then talks to the recipient’s inbound email server and transmits the message to them.
Finally, the recipient downloads the message from their email server.

It is step 2 that people are most concerned about when trying to understand if their email message is transmitted securely. They usually assume or check that everything is secure and OK at the two ends. Indeed, most users who need to can take steps to ensure that they are using SSL-enabled WebMail or POP/IMAP/SMTP/Exchange services so that steps 1 and 3 are secure. The intermediate step, where the email is transmitted between two different providers, is where messages may be sent insecurely.

To determine if the message was transmitted securely between the sender’s and recipient’s servers (over TLS), we need to extract the “Received” header lines from the received email message. If you look at the source of the email message, the lines at the top start with “Received.” Let’s look at an example message from a Hotmail user below. The email addresses, IPs, and other information are obviously fake.

LuxSci:

The Outlook email was sent to a LuxSci user. The Received headers appear in reverse chronological order, starting with the server that touched the message last. Therefore, in this example, we see the LuxSci servers first.

Received: from abc.luxsci.com ([1.1.1.1])
	by def.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfLgH003867
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 10:41:21 -0400
Received: from abc.luxsci.com (localhost.localdomain [127.0.0.1])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfK0Z030182
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 09:41:20 -0500
Received: (from mail@localhost)
	by abc.luxsci.com (8.14.4/8.13.8/Submit) id r7JEfKXD030178
	for user-xyz@def.luxsci.com; Mon, 19 Aug 2019 09:41:20 -0500

Received: from dispatch1-us1.ppe-hosted.com (dispatch1-us1.ppe-hosted.com [2.2.2.2])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfIkK030002
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <someone@luxsci.net>; Mon, 19 Aug 2019 09:41:19 -0500

Proofpoint:

LuxSci uses an email filtering service, Proofpoint. Messages reach Proofpoint’s servers before being delivered to LuxSci. Here’s what their servers report about the email transmission:

Received: from unknown [65.54.190.216] (EHLO bay0-omc4-s14.bay0.hotmail.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (envelope-from <someone@hotmail.com>);
	Mon, 19 Aug 2019 08:41:18 -0600 (MDT)

Outlook:

And finally, here’s what we see from Oultook’s server.

Received: from BAY403-EAS373 ([65.54.190.199]) by bay0-omc4-s14.bay0.outlook.com
       with Microsoft SMTPSVC(6.0.3790.4675); 
       Mon, 19 Aug 2019 07:41:19 -0700

How to Use Received Message Headers to Tell if the Email is Encrypted

The message headers contain information that can help us determine if an email is encrypted. Here are a few helpful notes to help you decode the text:

We said this above, but the message headers appear in reverse chronological order. The first one listed shows the last server that touched the message; the last one is the first server that touched it (typically the sending server).
Each Received line documents what a server did and when.
There are three sets of servers involved in this example: one machine at Hotmail, one machine at Proofpoint, where our Premium Email Filtering takes place, and some machines at LuxSci, where final acceptance of the message and subsequent delivery happened.

Presumably, the processing of email within each provider is secure. The place to be concerned about is the hand-offs between Hotmail and Proofpoint and between Proofpoint and LuxSci, as these are the big hops across the internet between providers.

In the line where LuxSci accepts the message from Proofpoint, we see:

(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)

This section, typical of most email servers running “sendmail” with TLS support, indicates that the message was encrypted during transport with TLS using 256-bit AES encryption. (“Verify=not” means that LuxSci did not ask Proofpoint for a second SSL client certificate to verify itself, as that is not usually needed or required for SMTP TLS to work correctly). Also, “TLSv1/SSLv3” is a tag that means that “Some version of SSL or TLS was used;” it does not mean that it was SSL v3 or TLS v1.0. It could have been TLS v1.2 or TLS v1.3.

So, the hop between Proofpoint and LuxSci was locked down and secure. What about the hop between Hotmail and Proofpoint? The Proofpoint server’s Received line makes no note of security at all! This means that the email message was probably not encrypted during this step.

Hotmail either did not support opportunistic TLS encryption for outbound emails, or Proofpoint did not support receipt of messages over TLS, and thus, TLS could not be used. With additional context, you can know which server supports TLS and which does not.

In this case, we know that Proofpoint supports inbound TLS encryption. In fact, from another example message where LuxSci sent a message to Proofpoint, we see the Received line:

Received: from unknown [44.44.44.44] (EHLO wgh.luxsci.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits))
	with ESMTP id b-022.p01c11m003.ppe-hosted.com
        (envelope-from <from@domain.com>);
	Mon, 02 Feb 2009 19:28:27 -0700 (MST)

The red text makes it clear that the message was indeed encrypted. Based on the additional context, we can deduce that the Hotmail sending server did not securely transmit the email using TLS.

How To Tell if an Email is Encrypted With TLS

When analyzing your message headers, consider the following items to determine if the email is encrypted:
1. The receiving server will log what kind of encryption, if any, was used in receiving the message in the headers.
2. Different email servers use different formats and syntax to display the encryption used. Look for keywords like “SSL,” “TLS,” and “Encryption,” which will signify this information.
3. Not all servers will record the use of encryption. While LuxSci has always logged encryption use, not every email service provider does. It is possible to use TLS encryption and not log it. Sometimes, there is no way to tell from the headers if a message is encrypted if it is not logged.
4. Messages passed between servers at the same provider do not necessarily need TLS encryption to be secure. For example, LuxSci has back-channel private network connections between many servers so that information can be securely passed between them without SMTP TLS. So, the lack of TLS usage between two servers does not mean the transmission between them was “insecure.” You may also see multiple received lines listing the same server: the server passes the message between different processes within itself. This communication also does not need to be TLS encrypted.
5. If you are a LuxSci customer, you can view online email delivery reports to see if TLS was used for any particular message. We record the kind of encryption in the delivery reports, so it’s easy to see which emails were encrypted.

How can you Ensure Emails Are Securely Transmitted?

With some servers not recording TLS in message headers, how can you determine if a message was transmitted securely from sender to recipient?

To answer this question accurately, you must understand the properties, servers, and networks involved. It may be easy to determine that the message was transmitted securely if included in the header information. However, the absence of information does not necessarily mean the message was insecurely transmitted. You can only know this if you know what each system’s servers record.

In our example of a message from Hotmail to LuxSci, you need to know that:

Proofpoint and LuxSci will always log the use of TLS in the headers. We can infer that the Hotmail to Proofpoint transmission was not secure as nothing was recorded there.
The transmission of messages within LuxSci’s infrastructure is secure due to private back channel transmissions. So, even though there is no mention of TLS in every Received line after LuxSci accepts the message from Proofpoint (in this example), transferring the messages between servers in LuxSci is as secure as using TLS. Also, the same server can add multiple received lines as it talks to itself. Generally, these hand-offs on the same server will not use TLS, as there is no need. In the LuxSci example, we see this as “abc.luxsci.com” adds several headers.
We don’t know anything about Hotmail’s email servers, so we don’t know how secure the initial transmissions within their network are. However, since we know they did not securely transmit the message to Proofpoint, we are not confident that the transmissions and processing within Hotmail (which may have gone unrecorded) were secure.

Was the email message sent and received using encryption?

We skipped steps 1 and 3 and focused on step 2 – the transmission between servers. Steps 1 and 3 are equally, if not more, necessary. Why? Because eavesdropping on the internet between ISPs is less of a problem than eavesdropping near the sender and recipient (i.e., in their workplace or local wireless hotspot). So, it’s essential to ensure messages are sent securely and received securely. This means:

Sending: Use SMTP over SSL or TLS when sending messages from an email client or use WebMail over a secure connection (HTTPS).
Receiving: Ensure your POP or IMAP connection is secured via SSL or TLS. If using WebMail to read your email, be sure it is over a secure connection (HTTPS).
WebMail: There is generally no record in the email headers to indicate if a message sent using WebMail was transmitted from the end-user to WebMail over a secure connection (SSL/HTTPS).

You can typically control one side and ensure it is secure; you can’t control the other without taking extra steps. So, what can you do to ensure your message is secure even if it might not be transmitted with encryption or if the recipient tries to access it insecurely?

You could use end-to-end email encryption (like PGP or S/MIME, which are included in SecureLine) or a secure web portal that doesn’t require the recipient to install or set up anything to get your secure email message. These methods meet HIPAA and other regulatory compliance requirements for secure data transmission and provide complete confidence that the message will be sent and received securely.

LuxSci’s SecureLine offers flexible encryption options, including TLS, secure web portal, PGP, and S/MIME. Its dynamic capabilities can determine what types of encryption the recipient’s server supports to ensure your emails are always sent securely.
