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.

Why is High Email Deliverability Essential for Healthcare Companies?

June 30, 2025
Pete Wermter

With email communication playing a critical role in the customer engagement strategies of virtually every organization, high email deliverability rates are vital to success across all industries. In the healthcare sector, however, the stakes can be far higher. An undelivered email isn’t merely an inconvenience or a lost sales opportunity; it could mean a missed appointment, a delay in a prescription refill, or a failure to get a patient critical healthcare information. Or worse, the email could end up in the hands of an unintended recipient, including bad actors and cybercriminals.

With this in mind, this post details why high email deliverability is essential for healthcare companies, as well as how your organization benefits from reliable and rapid email delivery.

Speed and Efficiency

The primary reason that high email deliverability is crucially important to healthcare organizations is to best guarantee essential communications that directly impact an individual’s healthcare journey reach them promptly. These transactional emails can include appointment reminders, prescription renewals, product order confirmations, test results, explanation of benefits notices, payment reminders, and invoices. Administrative notifications related to software or systems that a patient might use, such as a password reset for an online portal, also fall under the category of transactional emails.

When transactional emails are delayed or fail to reach people altogether, they can compromise a patient’s ability to access care, adhere to treatment plans, stay informed on key facets of their healthcare journey, and, ultimately, achieve optimal health outcomes.

When a patient fails to receive an expected email, such as a prescription confirmation, for example, it can leave them feeling confused and unsure of what to do next. For individuals who are sick, elderly, or managing chronic conditions, this can cause unnecessary stress, anxiety, and even compromise adherence to care plans.

In contrast, high email delivery rates create the opposite effect, helping patients get the communications and information they need. This increases their trust in your company and gives them a firmer sense of control over their healthcare journey.

Compliance with HIPAA Regulations

While the above point stresses the importance of reliable email delivery for the patient’s and customer’s benefit, healthcare companies also have a vested interest in ensuring communications reach the intended recipient for regulatory and patient privacy reasons.

To comply with the Health Insurance Portability and Accountability Act (HIPAA), emails that contain sensitive patient data, i.e., electronic protected health information (ePHI), must be securely delivered to the intended recipient. If, on the other hand, a communication containing ePHI fails to reach the intended recipient patient, that represents a failure in secure communications and a potential HIPAA violation for your organization.

After all, where did the patient’s data go? Was it delivered to the wrong person? Was it blocked by a spam filter and is left sitting unencrypted on a server somewhere?

If you can’t answer these questions, you could be exposed to a data breach, and it could result in a HIPAA violation, meaning your organization incurrs the associated consequences, including financial penalties and reputational damage. Conversely, deploying a fully HIPAA compliant email solution, such as LuxSci, supported by a dedicated infrastructure and designed for high email delivery enables your organization to include patient data in communications with confidence and ensure you messages land in the recipient’s inbox.

Greater Levels of Personalization and Engagement

Finally, high email deliverability rates are essential for healthcare organizations because they help drive greater levels of engagement with patients and customers. Higher email deliverability means better inbox placement, leading to more emails being opened, more links being clicked, and more conversions for your communications and campaigns.

In the case of healthcare retailers, for example, this equates to converting more prospects into customers and, consequently, maximizing the ROI of email marketing campaigns, in some cases with up to 80% better results.

While healthcare marketers, understandably, focus most of their efforts on crafting attention-grabbing headlines, personalizing the message content, and the email’s design elements, these factors are rendered irrelevant if the message fails to reach the recipient in the first place! When you take this into account, high email deliverability is a crucial component in optimizing the ROI of email communications and campaigns, and an all too often overlooked component at that.

What is a HIPAA Email API?

June 25, 2025
Ian Snipper

A HIPAA email API is a programming interface that allows healthcare applications to send secure emails containing protected health information while maintaining compliance with HIPAA regulations. These APIs provide developers with tools to integrate encrypted email functionality into healthcare software systems while automatically handling security requirements, audit logging, and PHI protection measures. Healthcare software development increasingly requires email capabilities for patient notifications, care coordination, and administrative communications. Standard email APIs lack the security controls and compliance features necessary for healthcare applications that handle sensitive patient data.

Technical Architecture and Security Framework

REST and SOAP protocols provide the foundation for most HIPAA email APIs, enabling healthcare applications to integrate email functionality through standard web service interfaces. These protocols support secure authentication and encrypted data transmission while maintaining compatibility with diverse healthcare technology environments. Message queuing systems help manage email delivery during high-volume periods while maintaining security controls throughout the transmission process. Healthcare applications can submit emails to secure queues where they receive encryption and compliance validation before delivery to recipients. Error handling mechanisms ensure that failed email transmissions do not compromise PHI security or leave sensitive data exposed in log files. HIPAA email APIs must provide detailed error information to developers while protecting patient information from unauthorized disclosure.

Authentication and Authorization Protocols

API key management provides secure access control for healthcare applications using email services. These keys must include appropriate permissions and expiration policies that prevent unauthorized access while enabling legitimate healthcare communications, allowing healthcare applications to authenticate users and obtain appropriate permissions for sending emails on their behalf. These protocols help ensure that only authorized personnel can trigger email communications containing PHI.

LuxSci supports three industry-standard authentication methods—alongside its proprietary LuxSci Secure option. These include:

OAuth 2.0 – The modern standard. Secure, flexible, and ideal for enterprise-scale integrations.
API Key – Simple and efficient. Ideal for server-to-server use when convenience matters most.
Basic Authentication – Straightforward, widely supported. Good for internal systems and quick testing.

For those who want the tightest possible control over API sessions—including HMAC signatures and session revocation—LuxSci Secure authentication remains the best option for customers.

Message Formatting, Template Management, and Security

MIME and S/MIME encoding support enables healthcare applications to send rich-text emails with attachments while maintaining encryption and security controls. These capabilities allow inclusion of medical images, test results, and formatted reports within compliant email communications. Template engines help healthcare developers create standardized email formats that include dynamic patient data while preventing inappropriate PHI disclosure. These systems can validate content against organizational policies before message transmission. Attachment handling procedures ensure that medical documents and images receive appropriate encryption and access controls when included in email communications. HIPAA email APIs must provide secure upload and transmission capabilities for healthcare file attachments.

Delivery Tracking and Status Reporting

Real-time delivery status updates help healthcare applications track email transmission progress and identify potential delivery issues. These status reports must provide actionable information without exposing PHI to unauthorized systems or personnel. Read receipt capabilities enable healthcare applications to confirm that recipients have accessed important medical communications. These features help care coordination while maintaining appropriate privacy protections for patient email interactions. Bounce management systems handle failed email deliveries appropriately while protecting PHI from exposure through error messages or automated responses. Healthcare applications need visibility into delivery problems without compromising patient privacy.

Compliance Logging and Audit Features

Automated audit trails capture detailed information about all email activities initiated through HIPAA email APIs. These logs must include sender identification, recipient information, transmission timestamps, and delivery status while protecting actual message content from unauthorized access. Compliance reporting features help healthcare organizations track their email usage patterns and identify potential policy violations. These reports can highlight unusual sending volumes, unauthorized recipient addresses, or messages that might violate PHI handling policies. Data retention controls ensure that API logs and message metadata comply with healthcare record-keeping requirements while managing storage costs and system performance. Healthcare organizations can configure retention periods based on their regulatory and operational needs.

Integration Patterns for Healthcare Applications

Electronic health record system (EHR), customer data platform (CDP), and Revenue Capture Management (RCM) platform integrations can enable automatic email messages and notifications to be sent based on clinical events like lab result availability or appointment scheduling changes. These integrations must respect minimum necessary standards while providing timely patient communications. Workflow automation allows healthcare applications to trigger email sequences based on patient care milestones or administrative requirements, tailoring communications based on user actions taken with each email. For example, healthcare organizations might send automated email reminders about upcoming appointments or medication refills. Batch processing capabilities enable healthcare organizations to send large volumes of patient communications efficiently while maintaining security controls and HIPAA compliance. These features support activities like appointment reminders, wellness newsletters, or billing notifications that affect many patients simultaneously.

Performance Optimization and Scalability

Rate limiting controls help healthcare organizations manage email volumes while preventing abuse or accidental bulk sending that might violate patient communication policies and damage your IP reputation. These controls can be customized based on organizational needs and user roles. Caching mechanisms improve API performance by storing frequently used templates and configuration data while maintaining appropriate security controls. These optimizations help reduce response times for healthcare applications without compromising PHI protection. Load balancing systems ensure reliable email delivery during peak usage periods when healthcare organizations send high volumes of patient communications. These systems must maintain security controls while distributing processing loads across multiple servers.

Testing and Development Support

Sandbox environments enable healthcare developers to test email functionality without exposing real patient data or sending communications to actual patients. These testing systems provide realistic API responses while using protected data that supports thorough integration testing. Documentation and code samples help healthcare development teams implement HIPAA email API functionality correctly while understanding security requirements and compliance obligations. These resources should include examples for common healthcare use cases and integration scenarios.

Finally, support services provide healthcare developers with technical assistance and compliance guidance during implementation and ongoing operations. API providers should offer expertise in both technical integration and healthcare regulatory requirements to ensure successful deployments.

What Is a HIPAA Compliant Email API?

June 23, 2025
Ian Snipper

HIPAA compliant email API enables healthcare applications to send automated emails containing protected health information through secure programming interfaces that meet HIPAA Security Rule requirements. These APIs provide encryption, access controls, and audit logging capabilities while allowing developers to integrate email functionality into healthcare software without compromising patient privacy or regulatory compliance. Healthcare software applications increasingly need automated email capabilities for appointment reminders, test results, billing notifications, and care coordination communications. Standard email APIs lack the security features and compliance controls necessary for transmitting PHI, requiring specialized solutions designed for healthcare use cases.

API Authentication and Access Controls

HIPAA compliant email APIs implement robust authentication mechanisms that verify the identity of applications and users before allowing access to email services. These systems typically use API keys, OAuth tokens, or digital certificates to establish secure communication channels between healthcare applications and email services. Role-based access controls allow healthcare organizations to limit API functionality based on user privileges and business needs. Appointment scheduling systems might have permission to send calendar reminders while being restricted from accessing patient medical records or billing information. Rate limiting and usage tracking help prevent unauthorized bulk email sending and detect potential security threats. API providers monitor usage patterns and can automatically restrict access when they detect unusual activity that might indicate compromised credentials or malicious use.

Message Encryption and Security Features

Email messages sent through HIPAA compliant APIs receive automatic encryption during transmission and storage. These systems typically support multiple encryption standards including TLS for transport security and end-to-end encryption for message content protection. Message validation features help ensure that emails containing PHI meet compliance requirements before transmission. APIs can check for proper authorization, validate recipient addresses, and verify that message content follows organizational policies for PHI disclosure.

Secure message delivery tracking provides confirmation when recipients receive and access encrypted emails. This audit trail helps healthcare organizations demonstrate compliance with HIPAA requirements and provides documentation for potential breach investigations or regulatory audits.

Integration with Healthcare Workflows

HIPAA compliant email APIs connect seamlessly with electronic health record systems, practice management platforms, and other healthcare applications. These integrations enable automated patient communications that trigger based on clinical events, scheduling changes, or administrative milestones. Template management systems allow healthcare organizations to create standardized email formats that ensure consistent messaging while maintaining compliance controls. Templates can include dynamic content from patient records while preventing unauthorized PHI disclosure through automated formatting rules. Event-driven messaging capabilities enable real-time communications based on healthcare system activities. Laboratory systems can automatically send encrypted test results to ordering physicians immediately after completion, improving care coordination and reducing manual data entry requirements.

Audit Logging and Compliance Tracking

HIPAA compliant email APIs maintain detailed logs of all messaging activities including sender identification, recipient information, message content summaries, and delivery status. These logs provide the documentation necessary for compliance audits and breach investigations. Automated compliance reporting features help healthcare organizations track email usage patterns and identify potential policy violations. Reports can highlight unusual sending volumes, unauthorized recipient addresses, or messages that might contain inappropriate PHI disclosures.

Data retention policies ensure that API logs and message archives meet HIPAA requirements while managing storage costs and system performance. Healthcare organizations can configure retention periods based on their compliance needs and operational requirements.

Developer Tools and Documentation

API documentation provides healthcare software developers with detailed technical specifications, code samples, and integration guides for implementing HIPAA compliant email functionality. These resources help development teams understand security requirements and implement proper PHI handling procedures. Software development kits (SDKs) simplify API integration by providing pre-built libraries for common programming languages and frameworks. These tools handle encryption, authentication, and compliance features automatically, reducing the risk of implementation errors that could compromise PHI security. Testing environments allow developers to validate their integrations without exposing real patient data. Sandbox systems provide realistic API responses while using synthetic data that enables thorough testing of email functionality and error handling procedures.

Scalability and Performance Considerations

HIPAA compliant email APIs must handle varying message volumes without compromising security or compliance controls. Healthcare organizations experience different email patterns based on patient schedules, clinical activities, and administrative cycles that require flexible capacity management. Load balancing and redundancy features ensure reliable email delivery even during peak usage periods or system maintenance activities. API providers typically maintain multiple data centers and failover systems that prevent service disruptions from affecting patient communications.

Performance analytics help healthcare organizations optimize their email communications and identify potential bottlenecks in their workflows. Metrics include delivery speeds, error rates, and system response times that enable proactive performance management and capacity planning.

What is a HIPAA Compliant Message?

September 25, 2024
Erik Kangas

A HIPAA compliant message securely transmits protected health information while meeting the Security Rule requirements for confidentiality, integrity, and availability. These messages include proper encryption during transmission, verification of recipient identity, access controls, and audit logging capabilities. Healthcare organizations must implement appropriate protections and establish usage policies governing how staff communicate protected health information to maintain compliance with HIPAA regulations.

Requirements for Secure Messaging

A HIPAA compliant message must incorporate several protections to safeguard patient information. Encryption during transmission prevents unauthorized interception of message contents while traveling between sender and recipient. Authentication mechanisms verify the identity of both senders and recipients before allowing access to message contents. Access controls restrict message viewing to authorized individuals with legitimate need for the information. Audit logging creates records of message sending, receipt, and viewing activities with timestamps and user identification. Message integrity protections prevent undetected alterations during transmission or storage. Organizations must implement these safeguards across all platforms used for sending HIPAA compliant messages, including email systems, patient portals, and secure messaging applications.

Message Content Considerations

]The content within a HIPAA compliant message must follow several guidelines to maintain regulatory compliance. Messages should include only the minimum necessary information required for the intended purpose, avoiding excessive disclosure of patient details. Identifiable patient information must be clearly separated from general communication content for proper protection. Message subjects and headers should avoid revealing protected health information that might be visible in notification previews. Disclaimers typically appear at message ends stating confidentiality requirements and instructions for unintended recipients. Healthcare organizations develop content templates that help staff compose a HIPAA compliant message with appropriate structure and security notices. Proper content structuring ensures information remains protected throughout its communication lifecycle.

Acceptable Messaging Platforms

Healthcare organizations can send HIPAA compliant messages through various platforms that meet security requirements. Secure email systems with encryption and access controls provide one common method for protected communications. Patient portal messaging offers a controlled environment where both providers and patients access information through authenticated sessions. Secure text messaging applications designed for healthcare use encrypt communications between clinical staff members. Telehealth platforms include messaging components that maintain security during virtual visits. Fax transmissions to verified numbers remain acceptable for many healthcare communications when received by authorized recipients. Regardless of platform choice, organizations must verify that protections, Business Associate Agreements, and usage policies align with HIPAA requirements for their selected communication channels.

Patient Authorization Requirements

HIPAA compliant messages containing protected health information must adhere to patient authorization requirements. Communications for treatment, payment, and healthcare operations generally proceed without specific patient permission. Messages for other purposes often require documented patient authorization before sending. Patient preferences for communication methods should be recorded and respected for all messages. Some patients may authorize unencrypted communications after being informed of the risks, though organizations should document these preferences carefully. Authorization requirements apply regardless of the security measures implemented for message transmission. Healthcare organizations must train staff to recognize which communications require patient authorization and how to properly document these permissions.

HIPAA Compliant Messaging Documentation

Healthcare organizations must maintain documentation about their HIPAA compliant messaging practices. Policies should clearly define what constitutes appropriate message content and which communication channels may be used for different information types. Procedure documents need to outline steps for sending protected information through various platforms. Training records demonstrate that staff understand proper messaging protocols and security requirements. Technology configurations for messaging systems should be documented to demonstrate appropriate security settings. Audit logs from messaging platforms provide evidence of compliance with access and monitoring requirements. This documentation helps organizations demonstrate their compliance efforts during regulatory reviews or investigations of potential violations.

Messaging Security Breach Prevention

Preventing security breaches represents a crucial aspect of maintaining HIPAA compliant messaging systems. Staff education about phishing threats and social engineering helps prevent credential theft that could lead to unauthorized message access. Message recall capabilities allow addressing accidental disclosures before they become reportable breaches. Automatic lockout after failed login attempts prevents password guessing attacks against messaging accounts. Message expiration and automatic deletion policies reduce the risk window for stored communications. Regular security assessments identify potential vulnerabilities in messaging systems before they can be exploited. Healthcare organizations combine these preventive measures with monitoring systems that detect potential messaging security incidents early, allowing rapid response before patient information becomes compromised.

HIPAA-Compliant Email Marketing FAQs

October 24, 2024
LuxSci

Email is an essential channel for most healthcare marketers, but HIPAA compliance requirements can make it challenging to execute effective engagement campaigns without violating patient privacy.

HIPAA is a complicated set of regulations that while offering a lot of guidance, does not mandate the use of any specific technologies to protect patient privacy. This ambiguity causes a lot of confusion for marketers looking to integrate email into their healthcare engagement campaigns.

With this in mind, this article addresses some frequently asked questions (FAQs) about HIPAA-compliant email marketing and offers advice for securing patient data and future-proofing your marketing.

Frequently asked HIPAA compliant email marketing questions

Do Generic Newsletters Need To Be Protected?

What Is An Email API?

Does HIPAA Allow Healthcare Providers To Send Unencrypted Emails With PHI To Patients?

Can Patients Exercise Their Right Of Access By Receiving PHI via Unencrypted Email?

Is Microsoft 365 Sufficient For Marketing Emails?

What Are Common Email Marketing Use Cases For Healthcare?

How Do I Find a HIPPA-Compliant Email Marketing Vendor?

Do generic newsletters need to be protected?

Some marketers assume newsletters from a healthcare provider or supplier do not contain health information and, therefore, do not fall under HIPAA requirements. This assumption, however, is often incorrect, with many surprised to learn that protected health information (PHI) can be implied from seemingly innocuous information.

As a result, many generic email newsletters often indirectly contain PHI due to the very fact that they are sent to lists of current patients or customers. This is because email addresses count as individually identifiable data and when combined with the message therein, it’s pretty simple to infer that they are patients or customers.

Let’s say, for example, that you send a newsletter to the patients of a dialysis clinic. An eavesdropper could infer that the recipients receive dialysis. Consequently, as the email reveals information about an individual’s health treatment, it contains PHI and should be secured in compliance with HIPAA regulations.

For the fundamental reason that it can be difficult to determine what classifies as PHI, it’s safer to skip the ambiguity entirely and use a HIPAA-compliant email marketing solution to ensure security.

What is an email API?

An Application Programming Interface (API) is a collection of protocols, or rules, that enable different applications to communicate with each other. APIs are a crucial aspect of modern applications – as they spare developers the considerable effort of creating application features from scratch – they can just connect to the API of an existing application.

For example, how many websites have you used that utilize Google Maps? This is because they have connected their site to the Google Maps API – integrating it into their application and providing another feature for their users.

In the case of an email API, it is a way for applications, such as customer relationship management (CRM) platforms, customer data platforms (CDP) and electronic health record (EHR) systems, to connect to email service providers. This then allows marketers to send emails through the application, using the ePHI (electronic protected health information) collected and stored within the application.

Additionally, marketers can view and further utilize campaign data through the powerful dashboards and analysis tools found in CRM systems and similar applications. Trigger-based transactional or marketing emails are ideal for sending with an email API, whereby emails are sent when pre-determined conditions in the application are met. Healthcare organizations may use email APIs to send appointment reminders using electronic health records system data about a patient’s upcoming appointments, check ups or treatments.

As invaluable as email APIs are, however, especially for streamlining and automation communication workflows, they are no substitute for a comprehensive email marketing platform. Email APIs do not include the contact management systems standard in most email marketing platforms, as all the data resides within the application they connect to. Additionally, email API tools do not typically include drag-and-drop editor tools and other design features that enable you to make your emails stand out and boost patient engagement.

Does HIPAA allow healthcare providers and companies to send unencrypted emails with PHI to patients?

Encryption is an addressable standard, i.e., it must be implemented by the organization unless a risk analysis concludes that implementation is not reasonable and appropriate, under the HIPAA Security Rule. This does not mean it is optional. The HIPAA Security Rule does not explicitly forbid unencrypted email. Still, it does state that “other safeguards should be applied to protect privacy reasonably, such as limiting the amount or type of information disclosed through the unencrypted email.”

In addition, the Department of Health and Human Services also states that “covered entities are permitted to send individuals unencrypted emails if they have advised the individual of the risk, and the individual still prefers the unencrypted email.” in response to this, some organizations use waivers to inform patients of the risks and acquire permission to send unencrypted emails.

However, we do not recommend this approach for several reasons:

Keeping track of waivers over time and recording status changes and updates is challenging – and increases your administrative overhead.
Signed waivers do not insulate you from the consequences of a HIPAA breach.
Using waivers to send unencrypted emails doesn’t absolve you of your other HIPAA obligations, such as data retention and disposal. Subsequently, using a HIPAA-compliant email solution is more manageable and eliminates ambiguity.

Can patients exercise their right of access of receiving PHI voa unencrypted email?

Yes, but they must be fully informed of the risks and sign waivers acknowledging them; the caveats detailed in the above answer apply. Consequently, it’s always best to use an encryption tool to protect patient data.

Is Microsoft 365 with encryption sufficient for sending marketing emails?

Microsoft 365 can be configured with Office Message Encryption (OME) to comply with HIPAA. However, it is not well-suited for sending marketing emails. OME primarily relies on portal pickup encryption, in which the message is stored securely on a server and requires the recipient to log in to the portal to read the email. As a result, the portal adds friction to the marketing process that prevents optimal engagement and constrains ROI.

Marketing messages containing light-PHI, i.e. low-risk data, are best sent using Transport Layer Security (TLS) encryption. TLS-encrypted messages arrive in the recipient’s inbox just like a regular email and do not require them to complete an additional step.

Additionally, Microsoft 365 is not configured to send high volumes of email. If you plan on executing large scale marketing campaigns, you could unintentionally disrupt regular business communications by sending all the messages through the same infrastructure. Instead, you should separate your business and marketing email delivery activities to protect your IP reputation, i.e., the trustworthiness of your IP addresses and how likely it is your emails end up in a spam folder, and achieve your desired sending throughput.

What are the common email marketing use cases for healthcare?

Email marketing in healthcare is not restricted to boring general practice newsletters and other communications that fail to engage patients. When you successfully harness tools that enable you to use ePHI to better target and personalize your healthcare engagement campaigns – the sky is the limit. With consumer preferences shifting toward digital communications, marketers who know how to best utilize HIPAA-compliant email marketing – and tactics like segmentation and personalization – will prove more effective at reaching patients.

Examples of ways that healthcare marketers can use email include:

Lead generation campaigns
Promotions
Verifications
Order confirmations
Notifications
Upsell & cross-sell
Collecting data on the patient experience

How do I find a HIPAA-compliant email vendor?

Using popular email marketing platforms, such as Mailchimp, is not recommended. Many of these platforms were designed for businesses, but are simply not secure enough to meet HIPAA requirements. We do not recommend using a solution not specifically equipped to meet the healthcare industry’s unique security and compliance needs. To determine if your email marketing provider is compliant, they must meet three broad criteria at a minimum.

The vendor must sign a Business Associate Agreement (BAA) outlining how they plan to secure your data and what they will do in the event of a breach.
Encrypt data at rest when it is stored in their systems.
Encrypt data, i.e., email messages, in transit as sent to the recipients.

Not all vendors will be up to the task. Carefully vet your email marketing vendors to ensure they are taking steps to secure data and protect patient privacy.

Conclusion

Admittedly, HIPAA can be difficult to understand – but choosing the right tools and adequately vetting your vendors makes it far easier to successfully execute HIPAA-compliant email marketing campaigns.

What is the Meaning of Patient Engagement?

November 28, 2024
Erik Kangas

Patient engagement refers to the active participation of individuals in their healthcare through informed decision-making, self-management, and collaborative relationships with providers. This approach involves patients taking an active role in their treatment plans, communicating with healthcare teams, and managing their health between clinical visits. Patient engagement connects to improved health outcomes, higher satisfaction, and more efficient healthcare delivery by creating partnerships between patients and their care providers.

Core Components of Patient Engagement

Patient engagement encompasses several elements that work together to create meaningful healthcare participation. Knowledge and education are the base of patient engagement, providing patients information about their health conditions and treatment options. Two-way communication channels allow patients to share concerns, ask questions, and provide feedback to their healthcare team. Self-management tools help patients monitor symptoms, follow treatment plans, and make health-promoting lifestyle changes. Shared decision-making involves patients and providers discussing options and selecting treatments that align with patient values and preferences. Technology platforms often support these components through patient portals, mobile apps, and remote monitoring devices. When combined effectively, these elements create healthcare experiences where patients actively participate rather than passively receive care.

Evolution of Patient Engagement Concepts

The understanding of patient engagement has developed over decades as healthcare delivery models have changed. Traditional paternalistic approaches positioned doctors as decision-makers with minimal patient input. The informed consent movement established patients’ rights to understand treatments before agreeing to them. Consumer-directed healthcare introduced market concepts with patients viewed as consumers making choices. Patient-centered care expanded this view by recognizing patients’ unique needs, preferences, and life circumstances. Modern patient engagement builds on these previous concepts while emphasizing active participation and partnership. This evolution reflects broader societal changes in information access, consumer expectations, and understanding of what creates effective healthcare. Today’s patient engagement models acknowledge that health outcomes improve when patients participate fully in their care.

Impact on Health Outcomes

Research consistently shows that effective patient engagement leads to improved health results across numerous conditions. Engaged patients typically experience better control of chronic diseases like diabetes and hypertension through more consistent medication adherence and lifestyle management. Surgical patients who actively participate in pre-procedure education and post-operative care plans often recover faster with fewer complications. Mental health treatment shows greater effectiveness when patients actively participate in therapeutic approaches and decision-making. Prevention efforts achieve better results when individuals engage in recommended screenings and health maintenance activities. These outcome improvements stem from better treatment adherence, earlier problem identification, and care plans that align with patients’ actual lives and capabilities. Healthcare organizations increasingly focus on patient engagement as a core strategy for improving clinical quality measures.

Healthcare System Benefits

Beyond individual health improvements, patient engagement creates advantages for healthcare systems and organizations. Engaged patients typically use healthcare resources more efficiently, with fewer unnecessary emergency department visits and hospitalizations. Appointment attendance rates improve when patients actively participate in scheduling and understand the purpose of visits. Preventive care utilization increases, potentially reducing costly interventions for advanced disease. Staff satisfaction often improves through more productive patient interactions and shared responsibility for outcomes. Healthcare organizations find that focusing on patient engagement helps meet quality metrics tied to value-based payment models. Patient feedback provides valuable insights for service improvements when organizations create meaningful engagement channels. These system benefits make patient engagement a strategic priority for healthcare organizations in competitive markets.

Technology and Patient Engagement

Digital tools have transformed how patient engagement functions in modern healthcare settings. Patient portals provide secure access to medical records, test results, and communication channels with care teams. Mobile health applications help patients track symptoms, medications, and health metrics between appointments. Wearable devices gather health data that patients and providers can use for monitoring and decision-making. Telehealth platforms extend access to care beyond traditional office visits. These technologies remove barriers to engagement by making information and communication more accessible regardless of location or time constraints. While technology alone doesn’t create engagement, thoughtfully designed digital tools can facilitate greater patient participation in healthcare activities and decisions. Healthcare organizations increasingly view technology investment as essential for effective patient engagement strategies.

Implementation Challenges and Solutions

Healthcare organizations face various obstacles when trying to improve patient engagement. Health literacy varies widely, affecting patients’ ability to understand medical information and participate in decisions. Digital access and technical skills create potential disparities in who can use engagement tools. Time constraints during appointments limit opportunities for meaningful patient-provider discussion. Healthcare teams may lack training in engagement techniques like shared decision-making and motivational interviewing. Organizations address these challenges through health literacy assessment and education programs, simplified communication approaches, and multiple engagement channel options beyond digital platforms. Staff training in patient activation methods helps healthcare teams support engagement effectively. Workflows redesigned to prioritize engagement activities create space for meaningful patient participation despite busy clinical environments.

Is Wix HIPAA Compliant?

December 18, 2024
Erik Kangas

Wix is not HIPAA compliant for healthcare websites that collect, store, or process protected health information. Wix does not offer Business Associate Agreements and lacks the necessary security features required for handling patient data under HIPAA regulations. While Wix provides user-friendly website building tools and basic security measures like SSL certificates, these features do not satisfy the requirements for healthcare data protection. Healthcare organizations need specialized platforms if they plan to handle protected health information on their websites.

Wix Platform Limitations for Healthcare

Wix website building tools focus on ease of use rather than healthcare compliance requirements. The platform uses shared hosting infrastructure that lacks the data isolation needed for sensitive health information. User authentication systems in Wix do not provide the access controls required by HIPAA regulations. Form data collected through Wix stores information in ways that don’t align with healthcare privacy requirements. The platform lacks audit logging capabilities to track who accesses patient information and when. Data backup systems do not include the encryption guarantees needed for protected health information. These structural limitations prevent Wix from serving as a platform for healthcare websites with patient data.

Business Associate Agreement Status

Healthcare organizations require Business Associate Agreements (BAAs) from any service provider handling protected health information. Wix does not offer BAAs for its website building platform or hosting services, making it legally impossible to use Wix for websites collecting or displaying patient information, regardless of added security measures. Wix’s terms of service do not address healthcare compliance or regulatory requirements, as the company focuses on general business and personal websites rather than regulated industries with strict data protection needs. Healthcare providers may assume website builders automatically support healthcare regulatory requirements without checking BAA availability.

Form Collection and Data Storage

Many healthcare websites collect patient information through online forms. Wix form builders store submitted information in ways that don’t meet HIPAA requirements. Form data typically resides in the Wix database without the encryption needed for protected health information. The platform lacks documentation about data storage locations and security measures applied to form submissions. Integration options for connecting form data to HIPAA compliant systems remain limited. Access to stored form data doesn’t include the detailed permission controls needed for healthcare information. These form handling limitations are challenging for healthcare websites that may need to collect patient information securely.

Acceptable Uses for Healthcare Organizations

Despite HIPAA limitations, Wix remains suitable for certain healthcare-related websites that don’t involve protected health information. Healthcare providers can use Wix for informational websites displaying services, provider details, location information, and general health resources. Marketing materials and educational content without patient-specific information work well on the platform. Healthcare organizations sometimes maintain separate websites, keeping public information on Wix while placing patient portals on HIPAA compliant platforms. This separation allows organizations to benefit from Wix’s user-friendly design tools for public-facing content while maintaining compliance for protected information.

Secure Alternatives for Healthcare Websites

Healthcare organizations have several alternatives for creating HIPAA compliant websites. Specialized healthcare website platforms include appropriate security measures and offer BAAs as standard practice. Content management systems like WordPress can be configured for HIPAA compliance with proper hosting and security implementations. Custom web development on compliant hosting environments provides maximum flexibility while meeting security requirements. Patient portal systems designed specifically for healthcare use include built-in compliance features. These alternatives typically require more technical knowledge or higher investment than Wix but provide the necessary security infrastructure for protected health information.

Website Compliance Assessment

Healthcare organizations should assess their website needs before selecting a platform. This process starts with determining exactly what information the website will collect and process. Organizations need policies defining what constitutes protected health information in their context. Security requirements should align with the sensitivity of information handled on the website. Budget considerations need to balance platform costs against compliance requirements and potential penalty risks. Technical resources available for website maintenance affect platform choices. This assessment helps organizations select appropriate website platforms and implement necessary security measures based on their needs
