Data-Driven Healthcare: Leveraging PHI for Personalized Patient Engagement

Patient Engagement, Popular Posts

February 28, 2025

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.

What you’ll learn:

The HIPAA Security Rule Missed Its May Deadline — Here’s What We Know

June 9, 2026
Pete Wermter

The proposed HIPAA Security Rule update has become one of the most closely watched healthcare compliance developments in recent years. Designed to strengthen cybersecurity protections for electronic protected health information (ePHI), the proposal could significantly reshape how healthcare organizations approach risk management, ePHI encryption, and mandatory email encryption requirements.

A final rule was expected as early as May 2026. However, that deadline has now passed without publication from the U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR).

So, what happens next—and what should healthcare IT directors, CISOs, and compliance officers do now?

Where Things Stand Today

The HIPAA Security Rule Notice of Proposed Rulemaking (NPRM) was published on January 6, 2025, with the goal of strengthening cybersecurity protections for ePHI in response to escalating ransomware attacks, healthcare breaches, and growing concerns about cyber resilience across the healthcare sector.

The proposal generated thousands of public comments from healthcare providers, payers, business associates, technology vendors, and industry groups. OCR has spent much of the past year reviewing this feedback and evaluating the operational and financial impact of the proposed changes.

Although the Spring Unified Regulatory Agenda identified May 2026 as a target date for a final rule, that milestone came and went without publication. As of June 2026, the proposed HIPAA Security Rule update remains under review.

While some organizations may be tempted to take a wait-and-see approach, the missed deadline should not be interpreted as a signal that the initiative has stalled. If anything, the proposal offers valuable insight into the future direction of healthcare cybersecurity regulation.

The Growing Focus on Mandatory Email Encryption

One of the most discussed aspects of the proposed HIPAA Security Rule update is encryption.

Under the current HIPAA Security Rule, encryption is generally classified as an “addressable” implementation specification. Organizations can choose alternative safeguards if they document and justify their decisions through a risk analysis process.

The proposed changes would significantly reduce that flexibility. Instead, many security safeguards, including encryption controls, would become more prescriptive and difficult to avoid.

While the final language has not yet been released, healthcare organizations should pay close attention to the proposal’s clear message: protecting ePHI through encryption is increasingly viewed as a baseline cybersecurity requirement.

This is particularly important for email communications.

Email remains one of the most widely used communication channels in healthcare, supporting everything from patient engagement and care coordination to billing, scheduling, and marketing communications. As regulators continue to focus on reducing data breach risks, mandatory email encryption is emerging as a likely area of increased scrutiny.

What Healthcare Organizations Should Do Now

The current delay creates an opportunity, not a reason to postpone action.

Healthcare organizations can begin preparing for likely requirements today by evaluating the security controls highlighted throughout the proposed rule.

Key areas to review include:

Encryption of ePHI across systems and communications channels
Comprehensive asset inventories and ePHI data mapping
Enhanced risk analysis and risk management processes
Multifactor authentication (MFA)
Vulnerability scanning and penetration testing
Incident response planning and testing
Backup and recovery procedures
Email security and secure email encryption practices

Organizations that proactively strengthen these areas now will be better prepared regardless of the final rule’s implementation timeline.

Why Secure Email Encryption Should Be a Priority

For many healthcare organizations, email remains one of the largest compliance and security risks.

Human error, misdirected messages, phishing attacks, and inconsistent encryption practices continue to contribute to breaches involving protected health information. As a result, secure email encryption is increasingly becoming a foundational component of healthcare cybersecurity strategies.

Organizations that rely on manual encryption processes or employee judgment alone may find it difficult to meet evolving regulatory expectations.

Instead, healthcare organizations should look for solutions that automate encryption decisions, reduce user error, and provide flexibility based on the sensitivity of the communication.

At LuxSci, we have long believed that security and usability must work together. We are 100% focused on secure healthcare communications, helping healthcare providers, payers, and suppliers protect sensitive data while improving patient and customer engagement.

Our unique SecureLine encryption technology enables organizations to apply the appropriate level of protection while maintaining a seamless experience for patients, customers, and staff.

For organizations already using Microsoft 365 or Google Workspace, LuxSci Secure Email Gateway can add HIPAA-compliant email security and encryption without requiring users to change their existing workflows. This approach helps reduce risk, while preserving productivity and user adoption.

The Bottom Line

The HIPAA Security Rule final rule may have missed its anticipated May deadline, but the cybersecurity challenges driving the proposal remain very real.

The OCR is still expected to make the rule change, which could require mandatory encryption of ePHI by early 2027.

The time to prepare is now!

Healthcare organizations should view the proposed HIPAA Security Rule update as an advance warning of where regulatory expectations are heading. Stronger cybersecurity controls, enhanced risk management, ePHI encryption, and mandatory email encryption requirements are all likely to remain central themes in future compliance efforts.

The organizations that begin preparing now will not only be better positioned for future regulatory changes, but will also strengthen their ability to protect patient data, reduce risk, and build trust in an increasingly challenging threat landscape.

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

May 12, 2026
Pete Wermter

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

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

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

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

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

For healthcare email security, the implications are significant.

Email = Healthcare Cybersecurity Risk

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

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

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

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

Recent OCR enforcement actions increasingly reflect these realities.

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

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

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

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

Email Encryption Is Moving From Addressable to Required

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

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

For healthcare email specifically, this creates several growing expectations:

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

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

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

Traditional MFA May No Longer Be Enough

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

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

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

For email environments, organizations should increasingly evaluate:

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

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

OCR Wants Proof, Not Just Policies

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

For email systems, organizations should be prepared to demonstrate:

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

This represents a broader shift in healthcare cybersecurity expectations.

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

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

Healthcare Organizations Need a New Email Security Strategy

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

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

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

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

How Do Healthcare Email Marketing Campaigns Work?

May 15, 2025
Erik Kangas

Healthcare email marketing campaigns are targeted communication strategies that healthcare organizations use to engage patients, promote wellness programs, share educational content, and encourage preventive care while maintaining HIPAA compliance and patient privacy protections. These campaigns differ from standard marketing approaches because they must balance promotional objectives with regulatory requirements and patient trust considerations. Healthcare providers, payers, and suppliers use healthcare email marketing campaigns to improve patient engagement, increase appointment bookings, promote health screenings, and provide valuable medical information to their communities. Understanding how healthcare email marketing campaigns function helps organizations develop compliant communication strategies that support patient care objectives while respecting privacy regulations and building stronger patient relationships.

Compliance Requirements For Healthcare Email Marketing Campaigns

Healthcare email marketing campaigns must comply with HIPAA privacy regulations when using patient information or communicating with current patients about their health conditions or treatment options. Organizations cannot use protected health information for marketing purposes without obtaining specific patient authorization, except for face-to-face communications or promotional gifts of nominal value. This means that targeted campaigns based on diagnosis codes, treatment history, or medication usage require explicit patient consent.

The CAN-SPAM Act applies to all commercial email communications, including healthcare email marketing campaigns, requiring clear sender identification, truthful subject lines, and easy unsubscribe mechanisms. Healthcare organizations must include physical addresses in their emails and honor unsubscribe requests promptly. These requirements apply regardless of whether campaigns target existing patients or potential patients in the community.

State privacy laws may impose additional restrictions on healthcare email marketing campaigns, particularly regarding the use of patient information and consent requirements. Organizations must evaluate applicable state regulations and implement the most restrictive requirements when multiple jurisdictions apply. Some states have specific rules about marketing to minors or individuals with certain medical conditions.

Patient consent mechanisms should clearly explain how email addresses will be used, what types of communications patients can expect, and how they can modify their preferences or opt out completely. Healthcare email marketing campaigns benefit from granular consent options that allow patients to choose specific types of communications while declining others. Documentation of consent helps demonstrate compliance during regulatory reviews.

Content Strategy And Patient Education Focus

Healthcare email marketing campaigns should prioritize educational content and patient value over promotional messaging to build trust and encourage engagement. Educational newsletters featuring seasonal health tips, preventive care reminders, and wellness information provide value to recipients while maintaining professional credibility. Disease-specific education campaigns can help patients manage chronic conditions and understand treatment options when properly targeted and authorized.

Preventive care campaigns promote routine screenings, vaccinations, and wellness visits that benefit patient health while supporting organizational revenue objectives. These campaigns can highlight the importance of annual check-ups, cancer screenings, and immunizations without requiring patient authorization since they promote general health services. Timing campaigns around health awareness months or seasonal health concerns improves relevance and engagement rates.

Content personalization in healthcare email marketing campaigns must balance engagement benefits with privacy requirements and technical capabilities. Generic personalization such as first names and preferred appointment times can improve response rates without requiring extensive patient information use. More detailed personalization based on health conditions or treatment history requires specific patient authorization and careful data management.

Health promotion campaigns can address community health issues, public health emergencies, or population health initiatives that benefit entire patient populations. These campaigns support organizational missions while providing valuable community services. Content should be accurate, evidence-based, and culturally appropriate for the target audience demographics and health literacy levels.

Segmentation And Targeting Strategies

Patient segmentation for healthcare email marketing campaigns should focus on demographic factors, service interests, and communication preferences rather than protected health information whenever possible. Geographic segmentation allows organizations to promote location-specific services and events without requiring patient authorization. Age-based segmentation can support appropriate messaging for different life stages and health needs.

Service line segmentation enables healthcare email marketing campaigns to promote specific departments or specialties to patients who have expressed interest or attended related events. Orthopedic services, women’s health programs, and cardiac care can be promoted to relevant audience segments based on self-reported interests rather than medical history. This approach maintains engagement while respecting privacy requirements.

Communication preference segmentation allows patients to select email frequency, content types, and communication channels that match their individual preferences. Some patients may prefer monthly newsletters while others want immediate alerts about health topics of interest. Preference management systems help maintain engagement while reducing unsubscribe rates and complaints.

Behavioral segmentation based on website interactions, event attendance, or previous email engagement can inform campaign targeting without using protected health information. Patients who visit specific web pages or attend health education events may be interested in related services or information. This targeting approach uses publicly observable behaviors rather than confidential medical information.

Technology Platforms And Integration Considerations

Healthcare email marketing campaigns require platforms that support HIPAA compliance, patient privacy protections, and integration with existing healthcare systems. Email marketing platforms used by healthcare organizations should provide business associate agreements, data encryption, audit logging, and secure data handling procedures. These platforms must protect patient information during campaign creation, delivery, and performance tracking.

Integration with patient relationship management systems allows healthcare email marketing campaigns to leverage patient preferences and communication history while maintaining privacy protections. Automated workflows can trigger campaigns based on appointment scheduling, discharge events, or routine care intervals without exposing sensitive medical information. These integrations improve campaign relevance while reducing manual workload.

List management capabilities should support consent tracking, preference management, and compliance reporting for healthcare email marketing campaigns. Organizations need systems that can document when and how patients provided consent for marketing communications. Automated consent renewal and preference update processes help maintain compliance as regulations and patient preferences change over time.

Analytics and reporting features should provide campaign performance metrics while protecting patient privacy and complying with data retention requirements. Healthcare organizations need to track engagement rates, conversion metrics, and patient feedback without creating unnecessary privacy risks. Aggregate reporting and anonymized analytics help measure campaign effectiveness while maintaining patient confidentiality.

Performance Measurement And Optimization

Healthcare email marketing campaigns should be evaluated based on patient engagement, health outcomes, and organizational objectives rather than purely commercial metrics. Open rates and click-through rates provide basic engagement measurements, but healthcare organizations should also track appointment bookings, screening completions, and patient satisfaction scores. These metrics better reflect the campaign’s impact on patient care and organizational mission.

Patient feedback mechanisms allow healthcare organizations to understand how recipients perceive email communications and identify opportunities for improvement. Surveys, focus groups, and direct patient comments provide insights into content preferences, communication frequency, and messaging effectiveness. This feedback helps optimize future healthcare email marketing campaigns while maintaining patient-centered approaches.

A/B testing can improve campaign performance by comparing different subject lines, content formats, or call-to-action approaches while maintaining compliance requirements. Testing should focus on elements that affect engagement and patient value rather than manipulative tactics. Results should guide evidence-based improvements to campaign strategy and content development.

Long-term performance tracking helps healthcare organizations understand the cumulative impact of email marketing efforts on patient relationships, care utilization, and health outcomes. Regular analysis of campaign performance supports continuous improvement and demonstrates the value of patient communication investments to organizational leadership and stakeholders.

What Is HIPAA Compliant Marketing for Healthcare?

April 4, 2025
Erik Kangas

HIPAA compliant marketing for healthcare refers to promotional communications that follow HIPAA Privacy Rule requirements when using or disclosing protected health information (PHI). Healthcare organizations can conduct marketing activities while protecting patient privacy by obtaining proper authorizations, implementing security measures, and ensuring all marketing communications meet regulatory standards for PHI protection. Healthcare marketing has changed dramatically with digital communication channels, yet patient privacy remains paramount. Organizations must balance effective marketing strategies with strict compliance requirements to avoid violations that can result in hefty penalties and damaged reputations.

Understanding Marketing Under HIPAA Regulations

HIPAA defines marketing as communications that encourage recipients to purchase or use products or services, with certain exceptions for treatment communications and health care operations. The regulation distinguishes between communications that require patient authorization and those that fall under permitted uses without authorization. Face-to-face marketing communications between healthcare providers and patients do not require written authorization under HIPAA rules. Similarly, promotional gifts of nominal value given during these encounters are permitted without further consent. Most other marketing activities involving PHI require explicit patient authorization before implementation.

Healthcare organizations must understand when their communications cross from permissible patient care activities into regulated marketing territory. Educational materials about treatment options generally qualify as health care operations, while promotional emails about cosmetic procedures usually require marketing authorizations.

Authorization Requirements for Healthcare Marketing

Written authorization forms the foundation of HIPAA compliant marketing for healthcare organizations. Patients must provide explicit consent before their PHI can be used for marketing purposes, and these authorizations must meet specific regulatory requirements to remain valid. Authorization forms must clearly describe what PHI will be used or disclosed, the purpose of the marketing activity, and who will receive the information. The form must also explain that patients can revoke authorization at any time and that refusal to authorize marketing communications will not affect their treatment.

Healthcare organizations receiving financial remuneration for marketing activities face stricter authorization requirements. When third parties pay for marketing communications, authorization forms must disclose these financial relationships and explain how patient information will be shared with outside entities.

Permitted Marketing Activities Without Authorization

Certain healthcare communications that might appear to be marketing can proceed without patient authorization under HIPAA. These include communications about the covered entity’s own health-related products or services, or communications for treatment, case management, care coordination, or preventive health programs. For example, hospitals may send newsletters about their own diabetes management programs or wellness initiatives without obtaining individual authorization. However, if the communication involves financial payment from a third party to promote their products or services, patient authorization is required.

Case management and care coordination communications also receive authorization exemptions when they promote health or wellness activities. Healthcare organizations can recommend disease management programs, wellness initiatives, or preventive care services without obtaining separate marketing authorizations.

Technology Solutions for Compliant Email Marketing

Email marketing platforms designed for healthcare must incorporate security features that protect PHI during transmission and storage. These systems encrypt communications, maintain audit logs, and provide controls that help organizations manage patient authorizations and preferences. Segmentation capabilities allow healthcare marketers to target specific patient populations while maintaining privacy protections. Organizations can send diabetes education materials to patients with relevant diagnoses without exposing individual health conditions to unauthorized recipients.

Automated opt-out mechanisms help healthcare organizations respect patient preferences and maintain compliance with both HIPAA and CAN-SPAM requirements. These systems track authorization status and automatically exclude patients who revoke consent from future marketing communications.

Managing Patient Data in Marketing Campaigns

HIPAA compliant marketing for healthcare requires careful handling of patient data throughout campaign development and execution. Organizations must implement policies that limit PHI access to authorized personnel and document all data usage for compliance auditing.Marketing teams need training on HIPAA requirements and access controls that prevent unauthorized PHI disclosure. Role-based permissions ensure that only personnel with legitimate business needs can access patient information for marketing purposes.

Data retention policies must align with HIPAA requirements and organizational needs. Healthcare marketers should establish schedules for deleting PHI when it is no longer needed for marketing activities and maintain documentation of data destruction for compliance records.

Compliance Auditing and Risk Management

Regular compliance audits help healthcare organizations identify potential vulnerabilities in their marketing practices and address issues before they result in violations. These assessments should review authorization procedures, data handling practices, and technology security measures. Risk assessment processes must evaluate both internal marketing activities and third-party vendor relationships. Business associate agreements become necessary when outside marketing companies access PHI, and these contracts must include appropriate safeguards and liability provisions.

Documentation requirements include maintaining records diligently to demonstrate commitment to HIPAA compliant marketing for healthcare activities and their ability to respond appropriately to potential breaches or violations.

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.

How to Secure SMTP Email Delivery with TLS

August 29, 2023
Erik Kangas

Secure email sending is a priority for organizations that communicate sensitive data externally. One of the most common ways to send secure emails is with SMTP TLS. TLS stands for Transport Layer Security and is the successor of SSL (Secure Socket Layer). TLS is one of the standard ways that computers on the internet transmit information over an encrypted channel. In general, when one computer connects to another computer and uses TLS, the following happens:

Computer A connects to Computer B (no security)
Computer B says “Hello” (no security)
Computer A says, “Let’s talk securely over TLS” (no security)
Computers A and B agree on how to do this (secure)
The rest of the conversation is encrypted (secure)

In particular:

The conversation is encrypted
Computer A can verify the identity of Computer B (by examining its SSL certificate, which is required for this dialog)
The conversation cannot be eavesdropped upon (without Computer A knowing)
A third party cannot modify the conversation
Third parties cannot inject other information into the conversation.

TLS and SSL help make the internet a more secure place. One popular way to use TLS is to secure SMTP to protect the transmission of email messages between servers.

Secure SMTP Email Delivery with TLS

The mechanism and language by which one email server transmits email messages to another email server is called Simple Mail Transport Protocol, or SMTP. For a long time, email servers have had the option of using TLS to transparently encrypt the message transmission from one server to another.

When available, using TLS with SMTP ensures the message contents are secured during transmission between the servers. Unfortunately, not all servers support TLS! Many email providers, especially free or public ones, have historically not supported TLS. Thankfully, the trend is shifting. LuxSci found that most providers now support TLS- approximately 85% of domains tested as of July 2022.

Using TLS requires that the server administrators:

purchase SSL certificates
configure the email servers to use them (and keep these configurations updated)
allocate additional computational resources on the email servers involved.

For TLS transmission to be used, the destination email server must offer support for TLS, and the sending computer or server must be configured to use TLS connections when possible.

The sending computer or server could be configured for:

No TLS: never use it.
Opportunistic TLS: use it if available; if not, send it insecurely.
Forced TLS: use TLS or do not deliver the email at all.

How Secure is Email Delivery over SMTP TLS?

TLS protects the transmission of the email message contents. It does nothing to protect the security of the message before it is sent or after it arrives at its destination. For that, other encryption mechanisms may be used, such as PGP, S/MIME, or storage in a secure portal.

For sending sensitive information to customers, transmission security is the minimum standard for compliance with healthcare and financial regulations. TLS is appropriate to meet most compliance requirements and offers an excellent alternative to more robust and less user-friendly encryption methods (like PGP and S/MIME).

There are different versions of TLS- 1.0 and 1.1 use older ciphers and are not as secure, while TLS 1.2 and 1.3 use newer ciphers and are more secure. When an email is sent, the level of TLS used is as secure as can be negotiated between the sending and receiving servers. If they both support strong encryption (like AES 256), then that will be used. If not, a weaker grade of encryption may be used. The sending and receiving servers can choose the types of encryption they will support. If there is no overlap in what they support, then TLS will fail (this is rare).

What About Replies to Secure Messages?

Let’s say you send a message to someone that is securely delivered to their inbox over TLS. Then, that person replies to you. Will that reply be secure? This may be important if you are communicating sensitive information. The reply will use TLS only if:

The recipient’s servers support TLS for outbound email (there is no way to test this externally).
The mail servers (where the “From” or “Reply” email address is hosted) support TLS for inbound email.
Both servers support overlapping TLS ciphers and protocols and can agree on a mutually acceptable means of encryption.

Unless familiar with the providers in question, it cannot be assumed that replies will use TLS. So, what should you do? Ultimately, it depends on what compliance standards you must meet, the level of risk you are willing to accept, and the types of communications you send. There are two general approaches to this question:

Conservative. If replies must be secure in all cases, assuming TLS will be used is unreasonable. In this case, a more secure method should be used to encrypt the messages in transit and store them upon arrival. The recipient must log in to a secure portal to view the message and reply securely. Alternatively, PGP or S/MIME could be used for additional security.
Aggressive. In some compliance situations like HIPAA, healthcare providers must ensure that ePHI is sent securely to patients. However, patients are not beholden to HIPAA and can send their information insecurely to anyone they want. If the patient’s reply is insecure, that could be okay. For these reasons, and because using TLS for email security is so easy, many do not worry about the security of email replies. However, this should be a risk factor you consider in an internal security audit. Consider nuanced policies that allow you to send less sensitive messages with TLS while sending more sensitive messages with higher security.

What are the Weaknesses of SMTP TLS?

As discussed, SMTP TLS has been around for a long time and has recently seen a great deal of adoption. However, it has some deficiencies compared to other types of email security:

There is no mandatory support for TLS in the email system.
A receiver’s support of the SMTP TLS option can be trivially removed by an active man-in-the-middle because TLS certificates are not actively verified.
Encryption is not used if any aspect of the TLS negotiation is undecipherable/garbled. It is very easy for a man-in-the-middle to inject garbage into the TLS handshake (which is done in clear text) and have the connection downgraded to plain text (opportunistic TLS) or have the connection fail (forced TLS).
Even when SMTP TLS is offered and accepted, the certificate presented during the TLS handshake is usually not checked to see if it is for the expected domain and unexpired. Most MTAs offer self-signed certificates as a pro forma. Thus, in many cases, one has an encrypted channel to an unauthenticated MTA, which can only prevent passive eavesdropping.

The Latest Updates to Secure SMTP TLS

Some solutions help remedy these issues—for example, SMTP Strict Transport Security. SMTP STS enables recipient servers to publish information about their SMTP TLS support in their DNS. This prevents man-in-the-middle downgrades to plain text delivery, ensures more robust TLS protocols are used, and can enable certificate validation.

In addition, users can adopt TLS 1.3. NIST recommends that government agencies develop migration plans to support TLS 1.3 by January 1, 2024. LuxSci supports both SMTP MTA-STS and TLS 1.3.

How Secure SMTP TLS Email Works with LuxSci

Inbound TLS

LuxSci’s inbound email servers support TLS for encrypted inbound email delivery from any sending email provider that also supports that. For selected organizations, LuxSci also locks down its servers to only accept email from them if delivered over TLS.

Outbound Opportunistic TLS

LuxSci’s outbound email servers will always use TLS with any server that claims to support it and with whom we can talk TLS v1.0+ using a strong cipher. The message will not be sent securely if the TLS connection to such a server fails (due to misconfiguration or no security protocols in common). Outbound opportunistic TLS encryption is automatic for all LuxSci customers, even those without SecureLine.

Forced TLS

When Forced TLS is enabled, the message is either dropped or sent with an alternate form of encryption if the recipient’s server does not support TLS. This ensures that messages will never be sent insecurely. Forced TLS is also in place for all LuxSci customers sending to banks and organizations that have requested that we globally enforce TLS to their servers.

Support for strong encryption

LuxSci’s servers will use the strongest encryption supported by the recipient’s email server. LuxSci servers will never employ an encryption cipher that uses less than 128 bits (they will fail to deliver rather than deliver via an excessively weak encryption cipher), and they will never use SSL v2 or SSL v3.

Does LuxSci Have Any Other Special TLS Features?

When using LuxSci SecureLine for outbound email encryption:

SMTP MTA STS: LuxSci’s domains support SMTP MTA STS, and LuxSci’s SecureLine encryption system leverages STS information about recipient domains to improve connection security.
Try TLS: Account administrators can have secure messages “try TLS first” and deliver that way. If TLS is unavailable, the messages would fall back and use more secure options like PGP, S/MIME, or Escrow. Email security is easy, seamless, and automatic when communicating internally or with others who support TLS.
TLS Exclusive: This is a special LuxSci-exclusive TLS sending feature. TLS Exclusive is just like Forced TLS, except that messages that can’t connect over TLS are just dropped. This is ideal for low-importance emails that must still be compliant, like email marketing messages in healthcare. In such cases, the ease of use of TLS is more important than receiving the message.
TLS Only Forwarding: Account administrators can restrict any server-side email forwarding settings in their accounts from allowing forwarding to any email addresses that do not support TLS for email delivery.
Encryption Escalation: Often, TLS is suitable for most messages, but some messages need to be encrypted using something stronger. LuxSci allows users to escalate the encryption from TLS to Escrow with a click (in WebMail) or by entering particular text in the subject line (for messages sent from email programs like Outlook).
Domain Monitoring: When TLS delivery is enabled for SecureLine accounts, messages will never be insecurely sent to domains that purport to be TLS-enabled, i.e., TLS delivery is enforced and no longer “opportunistic.” The system monitors these domains and updates their TLS-compliance status daily.
Double Encryption: Messages sent using SecureLine and PGP or S/MIME will still use Opportunistic TLS whenever possible for message delivery. In these cases, messages are often “double encrypted.” First, they are encrypted with PGP or S/MIME and may be encrypted again during transport using TLS.
No Weak TLS: Unlike many organizations, LuxSci’s TLS support for SMTP and other servers only supports those protocol levels (e.g., TLS v1.0+) and ciphers recommended by NIST for government communications and which are required for HIPAA. So, all communications with LuxSci servers will be over a compliant implementation of TLS.

For customers who can use TLS to meet security or compliance requirements, it enables seamless security and “use of email as usual.” SecureLine with Forced TLS enables clients to take advantage of this level of security whenever possible while automatically falling back to other methods when TLS is unavailable.

Of course, using Forced TLS as the sole method of encryption is optional; if your compliance needs are more substantial, you can turn off TLS-Only delivery or restrict it so that it is used only with specific recipients.

If your email use cases are complicated, LuxSci’s flexibility enables the secure sending of emails to any recipient, regardless of their email service provider’s support for TLS. Contact the LuxSci sales team to learn more about our secure SMTP TLS email sending.
