What Is Email Marketing For Healthcare?

Healthcare Marketing Compliance

Email marketing for healthcare is targeted communication strategy that medical organizations use to engage patients, promote wellness services, share health education content, and encourage preventive care while maintaining regulatory compliance and patient privacy protections. This specialized approach helps healthcare providers, payers, and suppliers build stronger relationships with their communities through informative, valuable email communications. Email marketing for healthcare differs from traditional marketing because it must balance promotional objectives with medical ethics, patient trust, and strict privacy regulations. Understanding email marketing for healthcare helps medical facilities develop communication programs that support patient engagement, improve health outcomes, and grow their practices while respecting regulatory requirements and maintaining professional standards.

The Use of Email Marketing For Healthcare

Email marketing for healthcare encompasses several communication types including patient education newsletters, appointment reminders, wellness program promotions, and health screening campaigns. Patient education emails provide valuable health information, seasonal wellness tips, and disease management guidance that helps recipients make informed healthcare decisions. These educational communications build trust and establish healthcare organizations as reliable health information sources.

Appointment and follow-up communications use email to streamline patient care coordination, reduce no-show rates, and improve treatment adherence. Wellness program promotions encourage patients to participate in health screenings, fitness classes, vaccination clinics, and other preventive care activities. Event marketing emails promote health fairs, educational seminars, and community health initiatives that benefit both patients and the broader community. Service line marketing allows healthcare organizations to promote specific departments or specialties to patients who have expressed interest in related services. Women’s health programs, cardiac care services, and orthopedic treatments can be marketed to relevant audience segments based on demographic factors and self-reported health interests rather than protected medical information.

Patient retention campaigns use email to maintain ongoing relationships with existing patients, encouraging regular check-ups, annual screenings, and continued engagement with healthcare services. These campaigns focus on long-term health maintenance rather than immediate sales objectives.

Regulatory Framework and Privacy Considerations

Email marketing for healthcare must comply with HIPAA privacy regulations that govern how protected health information can be used for communication purposes. Healthcare organizations cannot use patient medical records, diagnosis codes, or treatment histories for marketing without explicit written authorization from patients. General health education content can be sent without authorization, but targeted campaigns based on specific health conditions require proper consent procedures.

The CAN-SPAM Act applies to all commercial healthcare emails, requiring truthful subject lines, clear sender identification, valid physical addresses, and functional unsubscribe mechanisms. Healthcare organizations must honor opt-out requests promptly and maintain suppression lists to prevent future unwanted communications. State privacy laws may impose additional requirements that healthcare organizations must research and implement. Business associate agreements become necessary when healthcare organizations use third-party email platforms or service providers to handle patient information during marketing activities. These agreements ensure that vendors maintain appropriate privacy protections and comply with healthcare industry regulations. Healthcare organizations remain responsible for ensuring their email marketing practices meet all applicable regulatory requirements.

Patient consent management requires systems to track when and how patients provided authorization for different types of marketing communications. Organizations need documentation showing patient consent for targeted campaigns and procedures for updating preferences when patients change their communication choices.

Technology Platforms and Integration Requirements

Email marketing for healthcare requires specialized platforms that provide HIPAA compliance features, data encryption, audit logging, and business associate agreements. These platforms must protect patient information during campaign creation, delivery, and performance tracking while maintaining security standards appropriate for healthcare data. Standard consumer email marketing platforms may not provide adequate privacy protections for healthcare communications.

Integration capabilities allow email marketing for healthcare systems to connect with electronic health records, patient management platforms, and appointment scheduling systems. These integrations enable automated campaign triggers based on appointment dates, discharge events, or routine care intervals without exposing sensitive medical information to unauthorized personnel. Single sign-on features allow staff to access email marketing tools using existing healthcare system credentials. List management functionality should support consent tracking, preference management, and compliance reporting requirements specific to healthcare organizations. Segmentation tools need to work with demographic and behavioral data rather than protected health information to maintain privacy compliance. Automated workflows can personalize communications based on publicly available information and patient preferences.

Security monitoring and audit trails provide detailed logging of who accesses patient information, what campaigns are created and sent, and how patient data is used for marketing purposes. These features support compliance demonstrations during regulatory reviews and help organizations investigate potential privacy incidents.

Patient Engagement and Content Strategies

Email marketing for healthcare should prioritize patient value and health outcomes over purely promotional messaging to build trust and encourage long-term engagement. Educational content performs better than sales-focused communications because patients appreciate receiving useful health information that helps them make better healthcare decisions. Content should be evidence-based, medically accurate, and reviewed by qualified healthcare professionals before distribution.

Personalization strategies must balance engagement benefits with privacy requirements and regulatory constraints. Basic personalization using names, preferred languages, and geographic information can improve response rates without requiring protected health information. More detailed personalization based on health interests or conditions requires explicit patient authorization and careful data management procedures. Timing and frequency considerations help healthcare organizations maintain patient engagement without overwhelming recipients with excessive communications. Different types of healthcare emails may require different sending schedules based on urgency, content type, and patient preferences. Appointment reminders need timely delivery, while educational newsletters can follow regular monthly or quarterly schedules.

Interactive content such as health assessment questionnaires, symptom checkers, and wellness challenges can increase patient engagement while providing valuable health information. These interactive elements should collect only necessary information and maintain appropriate privacy protections throughout the user experience.

Performance Measurement and Optimization

Email marketing for healthcare should be evaluated using metrics that reflect patient engagement, health outcomes, and organizational objectives rather than purely commercial success indicators. Appointment booking rates, health screening participation, and patient satisfaction scores provide more meaningful performance measurements than traditional marketing metrics alone. These healthcare-specific metrics demonstrate how email communications support patient care and organizational mission.

Patient feedback collection through surveys, focus groups, and direct communication helps healthcare organizations understand recipient preferences and identify areas for improvement. Regular feedback collection demonstrates commitment to patient-centered communication approaches and provides insights for optimizing future campaigns. Feedback should guide content development, timing decisions, and overall communication strategy adjustments. A/B testing can improve campaign performance by comparing different subject lines, content formats, sending times, and call-to-action approaches while maintaining compliance requirements. Testing should focus on elements that affect patient engagement and health outcomes rather than manipulative tactics that might undermine patient trust.

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

HIPAA Compliant Email

Rethinking HIPAA Compliant Email – Not Just a Checkbox

The compliance-only mentality is outdated.

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

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

What Makes Email Truly HIPAA Compliant?

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

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

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

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

The Real Opportunity – Secure, Personalized Email with PHI

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

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

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

Here’s how secure, personalized email can drive improved results across a range of healthcare communications, including:

  • Increased Patient Appointments and Follow-ups – Sending encrypted, personalized appointment reminders and follow-up notices can reduce no-shows and boost overall appointment volume.
  • Boosting Preventative Care with Outreach Campaigns – Preventative campaigns (think flu shots or cancer screenings) sent securely to the right segments can lead to higher response rates, better health outcomes, and a lower cost of care.
  • Improving Health Plan Enrollments – Targeted email outreach during open enrollment, tailored by eligibility or plan type, and powered by automated workflows leads to higher enrollments and lower call center costs.
  • Driving Awareness and Sales of New Services or Products – Have a product upgrade offer, new wellness program or telehealth service? Send secure, PHI-informed HIPAA compliant email to the right audience for increased sales and faster adoption.
  • Optimize Explanation of Benefits NoticesReplace snail mail with email that’s fast, reliable and trackable, ensuring customers are informed and compliance is met.

The Healthcare Marketer’s Secret Weapon: Using PHI Responsibly

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

Meeting the Personalization Demands of Today’s Patients and Customers

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

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

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

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

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

Can a Website Be HIPAA Compliant?

A website can be HIPAA compliant when it incorporates security measures, privacy protections, and data handling practices that meet HIPAA regulatory requirements. Healthcare organizations must implement encryption, access controls, audit logging, and secure data storage for websites that collect, store, or transmit protected health information. A well configured HIPAA compliant website helps healthcare providers maintain patient privacy while offering online services.

HIPAA Website Requirements

Websites handling protected health information must meet the standards established in the HIPAA Security Rule. These requirements include encryption for data transmission using protocols like TLS 1.2 or higher. Access controls limit website data viewing to authorized personnel with appropriate login credentials. Audit logging tracks all user activities and data access attempts across the website. Session timeouts automatically log out inactive users to prevent unauthorized access. Regular security testing identifies and addresses potential vulnerabilities. These measures work together to protect patient information from unauthorized access or disclosure.

Website Hosting and Infrastructure

HIPAA compliant hosting provides the foundation for a secure healthcare website. When selecting a hosting provider, healthcare organizations look for companies willing to sign a Business Associate Agreement (BAA). This legal document establishes the hosting provider’s responsibilities for protecting health information. The physical location of servers matters, with many HIPAA compliant services using data centers with restricted access, environmental controls, and monitoring systems. Network protection typically includes firewalls, intrusion detection, and regular security updates. Organizations often choose dedicated hosting environments rather than shared servers to maintain data separation.

Patient Data Collection and Forms

Most healthcare websites collect information through online forms. HIPAA compliant websites include appropriate authorization language on these forms before gathering protected health information. Well-designed websites explain how patient data will be used in clear, accessible language. Form data requires protection both during transmission and after submission. Many websites use secure database connections and encryption for stored information. Healthcare organizations determine what information they actually need to collect, following the minimum necessary standard from HIPAA regulations. User-friendly form design can improve completion rates while maintaining compliance.

Secure Patient Portals and Interaction

Patient portals on HIPAA compliant websites allow secure access to medical records, appointment scheduling, and provider communications. These portals employ authentication measures like password requirements and account recovery processes. Many implement automatic timeout features that log out inactive users after a set period. Secure messaging features enable patient-provider communication without using standard email. The best patient portals maintain detailed logs of all system access and actions. Healthcare organizations integrate these portals with their electronic health record systems for data consistency and accuracy.

Mobile Responsiveness and App Integration

Modern HIPAA compliant websites function across various devices while maintaining security protections. Mobile responsive design allows patients to access information securely from smartphones and tablets. When healthcare organizations develop companion mobile apps, these applications need the same HIPAA compliance measures as their websites. Integration between websites and mobile applications requires secure API connections and consistent authentication methods. Many healthcare providers test their digital platforms across multiple devices to ensure both functionality and security. The mobile experience influences patient satisfaction with digital healthcare services.

Compliance Maintenance

Healthcare websites require regular updates and monitoring to maintain HIPAA compliance over time. Technology changes quickly, and security measures that worked previously may become outdated. Website administrators perform regular security scans and vulnerability testing. Organizations document these maintenance activities as evidence of compliance efforts. Staff training helps ensure everyone handling website data understands privacy requirements. As regulations evolve, websites need corresponding updates to privacy notices and security features. Many healthcare organizations work with compliance consultants who specialize in digital healthcare requirements.

How to Secure SMTP Email Delivery with TLS

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:

  1. Computer A connects to Computer B (no security)
  2. Computer B says “Hello” (no security)
  3. Computer A says, “Let’s talk securely over TLS” (no security)
  4. Computers A and B agree on how to do this (secure)
  5. 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:

  1. purchase SSL certificates
  2. configure the email servers to use them (and keep these configurations updated)
  3. 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:

  1. No TLS: never use it.
  2. Opportunistic TLS: use it if available; if not, send it insecurely.
  3. 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:

  1. The recipient’s servers support TLS for outbound email (there is no way to test this externally).
  2. The mail servers (where the “From” or “Reply” email address is hosted) support TLS for inbound email.
  3. 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:

  1. 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.
  2. 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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).
  6. 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.
  7. 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.
  8. 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.

The Risks of Third-Party Email Integrations for Healthcare Companies

Today’s healthcare organizations heavily rely on a variety of third-party organizations for a range of services and products. This includes applications (i.e., SaaS solutions), suppliers, partners, and other companies depended upon to serve their patients and customers.

As the healthcare industry evolves, companies will need to increasingly collaborate with external parties, or business associates, which creates several dependencies and risks.

In particular, third-party email platforms are integral to the operations of healthcare companies, and the sensitive nature of protected health information (PHI) contained in email communications raises the stakes exponentially.

This post analyzes the main risks associated with third-party email integrations. From there, we detail the most effective measures for safeguarding your company from the dangers of an insecure integration with an email delivery platform.

What Are The Risks of Third-Party Email Integrations?

Email applications are a pillar of the modern workplace, enabling companies to communicate almost instantly and facilitating greater productivity and efficiency. Email has transformed the speed at which transactions can take place and individuals receive the product or service they’ve purchased.

Consequently, the importance of email communication and the vast amounts of sensitive data it encompasses, makes it a contrast target – or “attack vector” for cybercriminals. Hackers and other malicious actors know that if they can infiltrate an organization’s email system, they have the potential to steal vast amounts of private or proprietary data. Just as alarmingly, they may simply use an insecure email platform as a backdoor into a company’s wider network, assuming greater control over their systems in an effort to maximize their financial gain or inflict maximum damage to an organization.

For healthcare companies with ambitious patient engagement goals, sharing protected health information (PHI) with a reliable third-party email provider is mandatory. Unfortunately, this comes with a litany of risks, which include:

  1. Data Breaches: weak security features in third-party email providers can expose PHI. 
  2. Misconfigured Permissions: misconfigurations and a lack of oversight control can result in personnel at third parties having excessive access to PHI.
  3. HIPAA Non-Compliance – if the integration does not support encryption, audit logs and other features mandated by HIPAA, you may drift into non-compliant territory.
  4. Financial Implications: violating HIPAA regulations can result in financial penalties, including fines and compensation to affected parties. 
  5. Reputational Damage: companies that fall victim to cyber attacks, especially through negligence, become cautionary tales and case studies for cybersecurity solution vendors. Data exposure that comes from an insecure email platform integration can have disastrous effects on your company’s reputation. 

Therefore, mitigating the risks of integrating a third-party email platform into your IT infrastructure, platforms and systems is crucial. This includes customer data platforms (CDP), electronic health record systems (EHR) and revenue cycle management platforms (RCM). Let’s move on to specific strategies on how to do so and, subsequently, better safeguard your organization’s PHI. 

How To Mitigate Email Integration Risk

Now that you have a better understanding of the potential risks that come with integrating an insecure third-party email solution into your IT ecosystem, let’s look at risk prevention. Fortunately, several strategies will significantly lower the risk of malicious actors getting their hands on the sensitive patient data under your care. Let’s take a look:

Verify A Third-Party Vendor’s Security Practices

Before sharing PHI with a vendor, ensure they have a strong cybersecurity posture. This makes sure they have measures such as encryption, access control (or identity access management (IAM), and continuous monitoring solutions in place, in addition to conducting regular risk assessments.

Similarly, it’s crucial to research an email provider’s reputation, including how long they’ve been in operation, the companies they count among their clients, and their overall standing within the industry. 

Business Associate Agreements (BAAs)

A business associate agreement (BAA) is a legal document that’s required for HIPAA compliance, when sharing PHI with third-party vendors, such as email services. It ensures that both you and the vendor formally agree to comply with HIPAA regulations and your respective responsibilities in protecting patient data.

Without a BAA, the above point about verifying a vendor’s security practices is moot. If they’re not willing to sign a BAA, their security stance is irrelevant, as your organization would have violated HIPAA regulations by not signing a BAA. More to the point, a HIPAA compliant email vendor will be eager to highlight their willingness to sign a BAA, as it advertises their ability to safeguard PHI and aid companies in achieving compliance. 

Encrypting PHI

Encryption needs to be a major consideration when it comes to integrating a third-party email services provider. Adequate encryption measures ensure that sensitive data is protected even in the event of its exfiltration or interception. Sure, the hackers now have hold of the PHI, but with proper encryption policies and controls, it will be unreadable, preserving the privacy of the individuals affected by the data leak.

With this in mind, encryption measures that mitigate third-party email integrations include automated encryption, which ensures PHI is always encrypted without the need for manual configuration, and flexible encryption, which matches the encryption level with the security standards of your recipients. 

Threat Intelligence

Unfortunately, cybersecurity never stands still. With the ever-evolving nature of cyber threats, healthcare organizations must keep up with the latest dangers to patient data. This means creating a process for discovering, and acting upon, the latest threat intelligence.

This could entail signing up for a threat intelligence service, or retaining the periodic services of an external threat intelligence expert. 

Developing An Incident Response Plan For Vendor-Related Breaches

The alarming reality of securing PHI is that, even with robust safeguards in place, such as continuous monitoring, a process for acquiring the latest threat intelligence, and generally following the advice outlined in this post, data breaches are still a stark reality. Cyber criminals will always target healthcare organizations, due to the value and sensitivity of their data and systems. Worse, even as security measures grow more effective, the tools that malicious actors have at their disposal become more sophisticated. It’s an arms race, and one that’s only been exacerbated by the introduction of AI, with both security professionals and cyber criminals honing their use of it for their respective purposes.

Taking all this into consideration, having a comprehensive incident response plan in place ensures your organization responds quickly and effectively to cyber threats, or even suspicious activity. Your incident response plan should:

  • Detail what employees should do if they suspect malicious activity.
  • Outline steps for investigation and containment.
  • When and how to notify affected parties.
  • Processes for disaster recovery and retaining operational continuity.

While it’s vital to develop a general incident response plan, having a specific set of protocols for security breaches caused by third-party vendors is especially prudent.

Choose a HIPAA-Compliant Email Provider

An efficient and convenient way of mitigating the risks of third-party email integrations is to deploy a HIPAA compliant email delivery platform for communicating with patients and customers.

Being well-versed with the safety requirements of healthcare organizations, HIPAA compliant email software features all the security required to safeguard PHI. In deploying a HIPAA compliant email provider, you also implement several of the strategies outlined above, such as encryption and signing a BAA (as a HIPAA compliant will offer a BAA). Accounting for this, taking the time to select the right HIPAA compliant email provider for your organization’s needs and goals should be a key part of your overall cyber threat defense strategy. 

Train Staff on Secure Email Communication Practices

Your staff is a considerable part of securing third-party email communications, so they must know the best practices for email security and safeguarding PHI. Comprehensive cyber threat awareness training ensures your personnel understand the risks of HIPAA non-compliance and follow the procedures you’ve set in place. Furthermore, the more responsibility an employee has in regards to PHI, the more comprehensive and regular their training needs to be.

Additionally, training, or “drilling”, if you will, on their roles in the incident response process increases its efficacy considerably and optimizes your response to attempts at unauthorized access to data.
