Are Replies to Encrypted Emails also Secure?

replying to an email

Sending HIPAA-compliant emails is easy when you use an encryption solution like LuxSci. But what happens when someone replies to an encrypted message? Are the replies also secure? This is primarily a concern when using SMTP TLS as a secure means of email delivery. 

This article will explain how messages are sent securely, how replies behave, and whether they are secure and compliant. At the end, we provide some recommendations for how to balance security and usability. 

How are HIPAA-compliant Secure Emails Sent?

In general, there are four ways to securely send HIPAA-compliant email messages to a recipient. The way the original message is encrypted will determine the nature of how secure the reply is.

PGP and S/MIME Encryption

LuxSci supports these highly secure email encryption methods for those who wish to use them. However, as they require more setup and coordination with your recipients, most HIPAA-compliant accounts use something other than PGP and S/MIME for business email communications. 

To send messages using PGP and S/MIME encryption, you must exchange certificates with the recipient and install them in the mail client to encrypt and decrypt messages. Some organizations will use this technology for internal communications because they can manage the setup. However, this method is impractical for securing large-scale external communications. When most people talk about encrypted email messages, they refer to one of the methods: secure web portal or SMTP TLS encryption.

Secure Web Portal Encryption

Messages that utilize the secure web portal method of encryption are secured, stored, and accessed via a secure database. It works like this. The sender’s message is sent to a secure web portal, and a simple notification message (that does not contain PHI) is sent to the recipient. The recipient clicks on a link in this notice, verifies their identity by logging in, and then can access the message within the portal.

This is very secure and works with any recipient’s email address. However, accessing the message requires extra work on the recipient’s part. They must log into the portal to read the secure message.

SMTP TLS Encryption

Messages encrypted with SMTP TLS appear like any other email in the recipient’s inbox. They are only encrypted as they are transmitted from the sender’s servers to the recipient’s servers. Unless the recipient knows where to look in the metadata, they may not know TLS-encrypted messages are secured at all. 

Unlike secure web portal encryption, which can send encrypted messages to any active email address, SMTP TLS can only be used to secure messages if the recipient’s email service supports the technology. Today, the majority of email providers support TLS. However, some older email service providers do not. If the recipient’s servers do not support TLS, you cannot send them encrypted messages using this technology.

Are Replies to Encrypted Emails Also Encrypted?

That brings us back to our original question: are replies to encrypted emails also secured? The answer will depend on what type of encryption was initially used. When your recipient replies to your HIPAA-compliant secure email message, here is what could happen: 

PGP and S/MIME Replies

We won’t spend much time discussing PGP and S/MIME, but we will answer the question. Replies to email messages secured with PGP and S/MIME encryption will also be encrypted, assuming all certificates are correctly configured.

Secure Web Portal Replies

Most secure web portals offer an option for the recipient to reply directly within the portal. If the recipient replies in the portal, the message is automatically secured with the same high level of encryption it was sent with.

However, we can’t assume that the recipient will use the portal to reply. Some people could use their email program to reply to the notification message instead of using the portal. In that case, the reply may or may not be secure, depending upon whether their email system supports TLS or other email security measures. It’s best to assume these replies to the notification message will be insecure.

Replies to SMTP TLS Messages

When a recipient replies to an email sent using SMTP TLS, they use their regular email system to send that message. This may or may not be secure, depending on whether their email system supports TLS or other email security measures. For HIPAA compliance reasons, you should assume that the message will be sent insecurely.

are replies also secure graphic

If the Reply to an Encrypted Message is Insecure, Is the Email Non-Compliant?

That leads us to an interesting follow-up question- if replies to encrypted messages are not secure, does this mean the system is non-compliant?

The short answer is: No.

Why? HIPAA only applies to covered entities and their business associates. To comply with HIPAA regulations, these organizations must properly secure any PHI transmitted or stored in their systems. Patients are not subject to HIPAA regulations. 

The patient can choose to send their information insecurely or use alternate channels like a phone call or in-person appointment to communicate their health information if concerned about the security of their account. When a patient replies to a message from their healthcare provider, they are transmitting their own information and do not have to do so securely.

Should SMTP TLS be Used to Send HIPAA-Compliant Secure Emails?

HIPAA is notoriously technology-neutral. It tells you what to do but not how to do it. As a result, what is minimally required and what is best are sometimes very different things. Because of that, customers have a wide range of expectations for how they would like things to work. 

At LuxSci, HIPAA-compliant email accounts have SMTP TLS enabled automatically, so every message is sent with a base level of encryption. This is for maximum usability. Customers can turn off SMTP TLS as the sole method of secure email delivery or use it only for selected recipients (like their co-workers). It is up to the customer to choose which encryption methods they think are best for their organization. At a minimum, using TLS is better than using no encryption, but each organization will have different requirements and risk factors.  

There are no compliance reasons why SMTP TLS should not be used. Still, organizations may want to reduce their risk by increasing the level of encryption when sending communications that contain PHI to patients.

Recommended Best Practices For Sending HIPAA-Compliant Secure Emails

The best practices for security are often at odds with the best user experience. This is often true in security and HIPAA compliance. Finding the right balance of security and usability is essential to protect patient data and meet business objectives. Utilizing TLS for some emails and secure web portal encryption for others is likely the best solution. When spreading awareness and engaging patients with low-sensitivity messages like appointment and vaccine reminders is the goal, using TLS (with some fallback or exclusion to avoid sending insecurely) is likely the right idea. When sending highly sensitive information like lab results, medical records, or billing statements, using a more secure form of encryption, like a secure web portal, is wise to reduce the risk of inappropriate disclosures.

HIPAA Compliant Email

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

With email security threats continuously increasing in number and sophistication, as well as healthcare companies requiring secure solutions to communicate with patients and customers, the need for HIPAA compliant email solutions has never been greater. 

However, when looking for the right secure email services provider (ESP), healthcare organizations run the risk of making inaccurate assumptions about HIPAA compliance via what they learn from prospective vendors. This is due to the tendency for sales materials for HIPAA compliant email services, such as web pages or promotional videos, to highlight the strengths of the platform, while downplaying a healthcare company’s own role and responsibilities in securing protected health information (PHI). 

With this firmly in mind, here are six key things that HIPAA compliant email salespeople don’t tell you about securing communications and achieving compliance. 

1. The Shared Responsibility Model

Firstly, HIPAA compliant email salespeople are unlikely to emphasize the idea of shared responsibility when it comes to data security. This is the idea that two entities that share access to data, e.g., a healthcare company and their ESP, have a shared responsibility to preserve the privacy of that data.

In reality, most sales pitches explain the benefits and features of the solution, as opposed to stressing that compliance truly depends on how it’s configured and used. Now, that’s not to say that a salesperson is trying to hide this fact, as they’ll probably allude to training and configuration requirements. But, they’ll be less likely to make light of this and, more broadly, how shared responsibility factors into compliance.

2. A BAA Doesn’t Automatically Make You HIPAA Compliant

A business associate agreement (BAA) is essential for HIPAA compliance, but signing one doesn’t automatically make you compliant. Your organization still has to use the email delivery solution in a way that aligns with HIPAA regulations, which involves proper configuration, training, oversight, and reporting.

The misconception among some healthcare companies that a BAA equals compliance may be perpetuated by the term “HIPAA compliant email services provider”.  This could give some the impression that the vendor is fully HIPAA compliant and, subsequently, in signing a BAA with them, the use of their services is fully compliant.

But, it’s not that simple.

Simply signing a BAA obscures the real effort involved in achieving compliance. There’s no official HIPAA seal of approval, and HIPAA compliant means that the solution is capable of being configured for compliant use, which is a shared responsibility. HIPAA compliant email salespeople are unlikely to volunteer this nuance, especially if their email solution requires considerable configuration or has a steep learning curve to use it securely.

3. Not All Solutions or Features Are HIPAA Compliant

Another key detail often underplayed by vendor sales materials of HIPAA compliant email solutions is that some of their features, or even entire services, aren’t covered by their BAAs, so they can’t be used to handle PHI. 

These tools are referred to as “out of scope” and may include tools capable of integration with the email service, such as analytics or AI capabilities, but they don’t possess the cyber risk mitigation measures that align with HIPAA regulations. Perhaps the main reason for this is that many mass-market email delivery solutions, such as Microsoft 365 or Google Workspace, are designed for companies across all sectors. Consequently, while they can be HIPAA compliant, they weren’t developed from the ground up with the stringent regulatory demands of the healthcare industry in mind.

4. Solutions Are Not HIPAA Compliant “Out of The Box”

HIPAA compliant email salespeople may suggest that compliance is built into their platform, and healthcare organizations can use it to transmit PHI straight away, but this isn’t the case. Healthcare companies must still configure the email platform accordingly, as per the security requirements determined by their risk assessment, e.g., applying the right level of encryption. 

Also, if the email service is difficult to configure for HIPAA compliance or if the vendor’s configuration documentation lacks detail, that presents another obstacle to its compliant use. 

In addition to configuration, healthcare companies also have to implement access management controls and policies, establishing the extent to which each employee can access PHI in respect to their roles and responsibilities. From there, they will have to train their workforce on how to use the HIPAA compliant email solution securely, which may include those tools that fall outside the scope of your BAA with the vendor, and must not be used for the disclosure of patient data.

5. Essential Security Features Cost Extra 

Another more egregious version of an ESP not being HIPAA compliant out of the box is having features required for compliance, such as encryption or audit logging, as premium add-ons and not included in the solution’s base pricing. 

A vendor’s sales materials for its email service might list the necessary safeguards, but underemphasize the fact that only some versions of their platform are truly HIPAA compliant. Consequently, healthcare companies must confirm that the features required for HIPAA compliant email communications are included in the plan they’re purchasing. 

6. The Importance of Staff Training on HIPAA

HIPAA compliant email salespeople are often remiss in stressing the need for additional workforce training alongside the deployment of their platform. A healthcare company’s employees must be trained on how to securely use the email client, how to ID potential threats, and best practices for including PHI in email communications, as well as the regulations tied to HIPAA and data security.

This includes educating users on the differences between regular and secure email, and what they must do to safeguard patient and customer data. Fortunately, secure email solutions from providers like LuxSci enable automated email encryption, and users do not need to take any additional actions to ensure encryption when sending emails.

Additionally, in some cases, employees will need to be trained on which tools or features do not align with HIPAA guidelines and must not be used to process PHI.

b2b medical marketing

What Does b2b Medical Marketing Help Healthcare Vendors Accomplish?

B2b medical marketing helps healthcare vendors to explain the practical value of a product to clinical and administrative buyers by presenting clear information that supports decision making across operational and regulatory domains. Buyers respond to communication that describes how a tool fits into routine workflows and how it handles information, and the process depends on steady explanations rather than promotional language.

Early Movement in the Buyer Relationship

The first stage of communication gives prospective buyers a clear sense of what the service does and why it belongs in their setting. Healthcare groups rely on predictable routines and they look for products that support those routines without creating unnecessary strain on staff. When an introduction explains how a tool fits into patient movement, documentation demands, or coordination between departments, readers can place the service into a familiar context. This lowers the cognitive effort required to evaluate whether further consideration is worthwhile and creates a smoother path for later discussions, which is why many vendors treat early stage explanations as the base of effective b2b medical marketing in this environment.

The Influence of Operational Structure

Clinical and administrative environments are shaped by long standing systems, varied software tools, and staff roles that have developed around known constraints. Vendors using b2b medical marketing describe how a product enters this environment so that the buyer can picture the transition from interest to adoption. Extended explanations of onboarding steps, data migration choices, and staff training routines help readers understand how daily operations shift when a new tool is introduced. These explanations allow decision makers to forecast workload changes rather than relying on assumptions, and they reflect the broader goal of b2b medical marketing which is to reduce uncertainty.

Regulatory Considerations in Vendor Communication

Healthcare buyers place great weight on regulatory matters, which is why clear descriptions of data handling are central to this type of communication. Readers look for information about access management, retention practices, audit preparation, and the path information takes through each component of a system. When vendors describe these areas in detail, compliance teams can perform early assessments and avoid long chains of clarification requests. This approach supports efficient internal review because the buyer gains confidence that the vendor maintains structured processes rather than improvised arrangements, and this clarity strengthens the overall impact of b2b medical marketing.

Reliability Expectations Within Clinical Settings

Healthcare settings cannot tolerate uncertainty in the systems that support patient care. B2b medical marketing provides insight into how a vendor manages service interruptions, planned updates, backup routines, and recovery efforts. A description of past events or internal procedures gives readers a sense of how the vendor behaves when conditions are difficult. Buyers place great value on this type of detail because it helps them differentiate between systems that hold up under stress and systems that falter when routine performance is disrupted, and these reliability discussions form a core thread in b2b medical marketing for clinical tools.

Perspectives That Influence Internal Decision Making

Each participant in the purchasing process evaluates a product through a different lens. Financial leaders consider long term spending patterns, clinical managers look for ease of use and effects on staff time, and compliance teams examine information practices. Communication that attends to these perspectives without shifting tone allows the reader to share information across departments with minimal friction. This prevents internal delays because each group can assess the service using information that relates to its role in the organisation, and thoughtful navigation of these viewpoints reinforces the strength of b2b medical marketing across healthcare markets.

The Role of Educational Content in Vendor Outreach

Healthcare groups respond well to educational material that speaks to challenges in clinical settings. Articles and guides that explain regulatory shifts, workflow bottlenecks, or mistakes observed in comparable organisations allow readers to examine their own processes. This form of communication helps buyers understand the vendor’s approach to problem solving and creates familiarity before any formal evaluation begins. Educational content performs well in this field because it demonstrates practical awareness rather than relying on abstract claims, making it a central component of many b2b medical marketing programs.

Use After Adoption

Decision makers frequently look beyond the moment of purchase and seek a clear view of the daily relationship that follows implementation. Communication describing staff support, update patterns, training formats, and communication channels helps buyers picture how the tool will fit into routine operations. Long paragraphs that describe the lived experience of using the service allow internal champions to advocate for the product with fewer unknowns, which supports faster movement through approval stages. This expectation of clarity after adoption aligns with the wider goals of b2b medical marketing which encourage predictable cooperation between vendor and buyer.

Documentation Supporting Review Processes

Healthcare organisations rely heavily on documentation during evaluation. Guides, records, administrative instructions, and explanations of data controls enable teams to examine the product without repeated requests for further detail. B2b medical marketing that introduces these documents early in the conversation reduces internal delays because reviewers can move through their procedures with all necessary information available at the outset. This transparent approach helps build trust between the vendor and the buyer and underscores the value of documentation as a recurring theme within b2b medical marketing.

B2b medical marketing works most effectively when vendors show an accurate grasp of clinical pressures and administrative realities. When communication reflects these conditions and acknowledges the challenges that healthcare groups experience during busy periods, readers gain confidence that the vendor understands the world they operate in. This supports deeper conversations about integration, performance, and long term cooperation across the organisation.

MailHippo HIPAA compliant

Is Mailhippo HIPAA Compliant?

MailHippo is considered HIPAA compliant when healthcare providers use a paid plan or 30-day free trial, sign a BAA, and enable the required security settings. As a result, MailHippo HIPAA compliant usage is only possible when all of these conditions are met. The cloud-based encrypted email service provides secure messaging for healthcare providers handling PHI, though considerations should be made in areas such as administrative controls, audit logging, and integration options. Healthcare providers considering MailHippo for patient communications should examine its security capabilities alongside potential workflow capabilities before making a decision on implementation.

Email Security Requirements Under HIPAA

Healthcare email systems handling PHI must satisfy federal privacy regulations through encryption, access controls, and audit capabilities. Data encryption during transmission prevents unauthorized interception of patient information traveling across public networks. Storage encryption protects archived messages containing health data while they reside on email servers. Access restrictions ensure that only authorized personnel can view patient communications relevant to their job responsibilities.

Audit controls track who accesses email systems, what messages they view, and when these activities occur. Integrity safeguards prevent unauthorized modification or deletion of patient communications that might compromise medical records or compliance evidence. Business associate agreements create legal frameworks defining how email service providers protect patient information and respond when security incidents occur.

Consumer email platforms lack typically these protections in their standard configurations, creating compliance vulnerabilities when healthcare providers use them for patient communications. For example, Gmail, Outlook, and Yahoo Mail were designed for general business use rather than regulated healthcare environments. To summarize, healthcare organizations benefit from email services that implement HIPAA security requirements by design rather than requiring complex manual configurations that might be implemented incorrectly.

The MailHippo Service Model

MailHippo positions itself as a straightforward encrypted email solution for professionals in regulated industries including healthcare, legal, and financial services. The cloud-based platform eliminates time-consuming software installation requirements, allowing users to send secure messages through web browsers without downloading applications. This simplicity appeals to solo practitioners and small medical practices that lack dedicated IT support staff.

Independent healthcare providers, small medical offices, mental health professionals, and insurance consultants represent the service’s primary user base. These smaller operations value ease of use over advanced features, preferring solutions that deliver basic security without complicated setup and user procedures. It’s important to note that MailHippo delivers encrypted messages to recipients through secure web portals rather than standard email clients, creating protected communication channels that don’t require recipients to install special software.

The MailHippo service model focuses on one-to-one secure messaging rather than bulk communications or automated workflows. Healthcare providers send individual messages to patients or colleagues through encrypted channels that protect information during transmission and storage. Recipients receive notifications that secure messages await them in web portals where they can view content after authentication. This approach works for routine patient communications but may not support more complex healthcare communication needs. For larger organizations that prefer users staying within a dedicated email application or need high volume sending, several HIPAA compliant alternatives exist, including LuxSci.

MailHippo’s HIPAA Compliant Encryption and Security Features

MailHippo features transport encryption using TLS protocols, protecting messages during transmission between email servers, and preventing interception while communications travel across networks. AES-256 encryption secures stored messages, ensuring that archived communications remain protected if servers are compromised. The combination of transmission and storage encryption addresses HIPAA requirements for protecting ePHI throughout its lifecycle.

Recipient access through secure web portals eliminates the vulnerabilities associated with delivering encrypted content through standard email clients. Patients and healthcare providers authenticate themselves before viewing message content, creating additional security layers beyond basic encryption. Using a portal-based approach reduces exposure through compromised email accounts or insecure devices that might not maintain proper security configurations.

Authentication requirements mandate that users log in before sending or receiving messages, preventing unauthorized access to patient communications. MailHippo supports two-factor authentication (2FA), but the company’s documentation doesn’t clearly spell out which MFA methods are available or whether organizations can enforce MFA for all users. Healthcare entities that require strong authentication factors, such as hardware tokens or biometrics should confirm these details directly with the vendor.

Delivery and read receipts provide tracking information about message transmission and recipient access. These receipts confirm that messages reached intended recipients and document when recipients viewed content. The tracking capabilities, while useful for confirming communication delivery, lack the detailed audit logging that larger healthcare organizations likely need for compliance and security investigations.

Third-Party Email Provider Contract Requirements

Federal regulations classify email service providers handling PHI as business associates subject to HIPAA compliance obligations. Healthcare entities must execute written agreements with these providers defining responsibilities for protecting patient data and responding to security incidents. Without signed BAAs, email communications containing patient information violate HIPAA regardless of encryption or other security measures implemented.

MailHippo HIPAA compliant email requires executed business associate agreements between the service provider and healthcare organizations. The company offers these agreements to paying and free trial customers who specifically request them. However, long-term free subscription plan users cannot obtain business associate agreements, making those accounts unsuitable for transmitting protected health information even when encryption features are enabled.

Business associate agreements specify encryption standards, incident notification timelines, and procedures for handling patient data when service relationships terminate. These contracts allocate liability between healthcare organizations and email providers, protecting organizations from financial exposure when security breaches that result from provider negligence. Agreement terms should address data retention requirements, geographic restrictions on information storage, and secure deletion methods when retention periods expire.

Healthcare organizations implementing MailHippo HIPAA compliant solutions must verify that executed agreements cover all anticipated uses of the platform. Agreements should explicitly permit transmission and storage of PHI while defining what security measures the provider maintains. Without proper agreements in place, healthcare organizations assume full liability for any security incidents involving patient communications transmitted through the platform.

Administrative Control & Potential Limitations

User management capabilities determine how healthcare organizations control access to email systems and enforce security policies across multiple staff members. Role-based permissions enable organizations to grant different access levels to physicians, nurses, administrative staff, and billing personnel based on their job functions. Centralized administration consoles allow IT staff or practice managers to oversee all user accounts, modify permissions, and review security concerns from a single interface.

MailHippo HIPAA compliant implementations may lack the administrative tools that larger healthcare organizations require, including managing large numbers of users. The platform does not provide role-based permission structures that restrict access based on job functions or patient care relationships. Centralized dashboards for overseeing user activities across organizations are absent, making it more difficult for administrators to monitor security compliance or identify potential policy violations.

Integration & Workflow Considerations

Healthcare communication workflows rely heavily on integration between email systems, electronic health records, practice management software, and patient engagement platforms. Automated workflows reduce administrative burden while ensuring consistent security practices across all patient communications. API connectivity enables different healthcare applications to exchange information seamlessly without requiring manual data transfer, which increases the risk of human error.

While MailHippo publishes an email API, it does not offer ‘out-of-the-box’ integration capabilities with electronic health record systems or practice management platforms. As a result, healthcare organizations cannot automatically populate patient communications with appointment information, test results, or treatment updates from their clinical systems without technical integration work.

Marketing automation and bulk communication capabilities do not exist within the MailHippo service model, which is designed for individual message transmission. Healthcare organizations conducting patient outreach, appointment reminders, or health education campaigns need alternative solutions for these activities. The focus on one-to-one messaging limits the platform’s utility for organizations with diverse communication requirements high-volume sending needs beyond routine secure messaging.

Appropriate Use Cases and Organizational Fit

Solo practitioners and small medical practices with straightforward communication needs represent ideal candidates for MailHippo HIPAA compliant email. These organizations likely value simplicity over advanced features, preferring solutions that deliver basic security without requiring technical expertise to configure and maintain. Single physicians or therapists communicating with individual patients benefit from the portal-based secure messaging that protects patient information without complicated setup procedures.

Healthcare providers requiring only basic one-to-one secure messaging without forms, complex integrations, or user management can operate effectively within the platform’s capabilities. For example. mental health professionals conducting therapy practices, independent consultants providing healthcare advice, and small specialty clinics with limited communication volumes fit the service model well.

Larger healthcare organizations, multi-location practices, and operations with complex communication requirements and workflows will find the platform’s limitations constraining. Organizations needing multiple user tiers, departmental segregation, or centralized administration lack the tools necessary for managing these structures. Healthcare systems requiring electronic health record integration, automated workflows, or bulk communication capabilities often need more comprehensive email security platforms than MailHippo HIPAA compliant setups can provide.

Implementation and Compliance Verification

Now, it’s important to note that healthcare organizations implementing secure email must verify that all HIPAA requirements are satisfied before transmitting PHI. Proper configuration helps ensure that encryption activates properly, access controls function as intended, and audit logging captures necessary security events. In addition, business associate agreement execution creates legal frameworks before any patient data flows through email systems.

As with any ESP for healthcare, organizations adopting MailHippo HIPAA compliant email should document their compliance measures, including executed agreements, security configurations, and staff training records. Documentation demonstrates due diligence during regulatory audits while providing evidence that organizations took appropriate steps to protect patient information. Policy development establishes guidelines about what information can be transmitted via email and what alternative communication methods should be used for particularly sensitive content.

Staff training prepares healthcare workers to use secure email systems properly while maintaining patient privacy throughout communications. Training should cover portal access procedures, recipient verification methods, and appropriate content guidelines that prevent inadvertent disclosures. Documented training records prove that organizations educated staff about security requirements before granting email system access.

Finally, periodic security assessments verify that email systems continue meeting compliance requirements as technology and threats evolve. Assessment schedules should include configuration reviews, access control testing, and verification that business associate agreements remain current. Healthcare organizations relying on MailHippo HIPAA compliant workflows must treat email security as an active process rather than a one-time setup, maintaining vigilance about vulnerabilities and regulatory changes.

HIPAA Compliant Email Use Cases for Healthcare Retailers

Today’s digital-first consumers expect the same convenience and personalization from their healthcare providers that they get from their favorite retailers and service providers. However, unlike companies in other sectors, there’s far less room for error for healthcare organizations, especially when it comes to privacy and data security. 

Whether a local pharmacy, online provider of glasses, a wellness store, or a nationwide retail health clinic, the key to building long-term loyalty and ensuring trust with your customers lies in trusted, meaningful communication that’s timely, relevant – and, above all, secure.

As a result, HIPAA compliant email is a strategic component for reliable and effective communication with your customers.

But, what about HIPAA?

Far from being a roadblock, HIPAA compliance is actually an enabler for retail healthcare brands that want to deliver more personalized, more targeted messaging without putting customer trust, or their sensitive personal data, at risk.

In this post, we dive into the most impactful email use cases for retail healthcare providers, as well as how deploying a secure email delivery platform like LuxSci can unlock more meaningful engagement, greater loyalty, and accelerated growth for your company.

Why Email Remains a Top Channel for Retail Healthcare

Email Is Everywhere – Because It Works

Email isn’t just for work or spam folders. It’s the preferred communication channel for tens of millions of health-conscious consumers across all demographics. People are accustomed to receiving alerts from their pharmacies, reminders from clinics, and promotions from their preferred wellness brands – all in one convenient place – and email is an important part of the mix.

When deployed securely, email becomes a powerful, personal, and persistent touchpoint for healthcare engagement.

HIPAA Compliance Enables Trust and Transparency

While your customers crave convenience, they also demand privacy – especially when it comes to their health. HIPAA compliant email ensures that personal health data and protected health information (PHI) stays precisely that – protected – while enabling retail healthcare brands to deliver personalized communications that build trust and loyalty.

HIPAA Compliance Helps Ensure Secure Healthcare Marketing

HIPAA doesn’t restrict your ability to communicate; conversely, it defines how you can do it securely and best perform, while protecting the sensitive data under your care. When emails contain PHI, you need to ensure:

  • Email content encryption
  • Access controls
  • Secure storage and transmission
  • A signed Business Associate Agreement (BAA) with your email provider

With the key HIPAA requirements in place, retail healthcare organizations can send high-impact, personalized, and, with some platforms, such as LuxSci, automated emails to engage and educate their customers – all while adhering to HIPAA compliance regulations.

How HIPAA Compliant Email Improves Retail Results

HIPAA compliant email doesn’t just check a box – it opens the door for personalized, proactive, and performance-driven customer and patient engagement. With the right strategy and the right HIPAA compliant email services provider, healthcare retailers can:

  • Deliver marketing messages that include PHI with confidence
  • Develop trust and customer loyalty through secure, reliable, and frequent communication
  • Increase new and repeat purchases and average order value (AOV)
  • Lower operational costs in comparison to phone and physical mail-based engagement campaigns

HIPAA Compliant Email Use Cases for Healthcare Retailers

Now, let’s look at six essential use cases that healthcare retailers can employ for more effective customer and patient engagement.  

Use Case #1: New Product Announcements

How Do You Know if Software is HIPAA Compliant?

How Do You Know if Software is HIPAA Compliant?

As in any industry, the healthcare sector is eager to embrace any new technology solution that increases productivity, enhances operational efficiency, and cuts costs. However, the rate at which healthcare companies – and their patients and customers – have had to adopt new software and digital tools has skyrocketed since the pandemic. And while a lot of this software is beneficial, a key question arises: is it HIPAA compliant? While an application may serve an organization’s needs – and may be eagerly embraced by patients – it also needs to have the right measures in place to safeguard protected health information (PHI) to determine if it is indeed HIPAA compliant.

Whether you’re a healthcare provider, software vendor, product team, or IT professional, understanding what makes software HIPAA compliant is essential for safeguarding patient data and insulating your organization from the consequences of falling afoul of HIPAA regulations. 

With this in mind, this post breaks down the key indicators of HIPAA compliant software, the technical requirements you should look for, and best practices for ensuring your software is HIPAA compliant.

What Does It Mean for Software to Be HIPAA-Compliant?

The Health Insurance Portability and Accountability Act (HIPAA)  sets national standards for safeguarding PHI, which includes any data related to a patient’s health, treatment, or payment details. In light of this, any applications and systems used to process, transmit, or store PHI must comply with the stringent privacy, security, and breach notification requirements set forth by HIPAA.

Subsequently, while healthcare organizations use a wide variety of software, most of it is likely to be HIPAA-compliant. Alarmingly, many companies aren’t aware of which applications are HIPAA-compliant and, more importantly, if there’s a need for compliance in the first place.   

However, it’s important to note that HIPAA itself does not certify software. Instead, it’s up to software vendors to implement the necessary security and privacy measures to ensure HIPAA compliance. Subsequently, it’s up to healthcare providers, payers, and suppliers to do their due diligence and source HIPAA compliant software. 

How to Determine If Software Is HIPAA Compliant

So, now that we’ve covered why it’s vital that the applications and systems through which sensitive patient data flows must be HIPAA compliant, how do you determine if your software meets HIPAA requirements? To assess whether software is HIPAA compliant, look for these key indicators:

1. Business Associate Agreement (BAA)

A HIPAA compliant software provider must sign a Business Associate Agreement (BAA) with covered entities, i.e., the healthcare company. A BAA is a legal contract that outlines the vendor’s responsibility for safeguarding PHI. If a software provider doesn’t offer a BAA, their software is NOT HIPAA compliant.

Now, if a vendor offers a BAA, it should be presented front and center in their benefits, terms or conditions, if not on their website homepage as part of their key features. If a vendor has taken the time and effort to make their infrastructure robust enough to meet HIPAA regulations, they’ll want to make it known to reassure healthcare organizations of their suitability to their particular needs.  

2. End-to-End Encryption

A key requirement of the HIPAA Security Rule is that sensitive patient data is encrypted end to end during its transmission. This means being encrypted during transit, i.e., when sent in an email or entered into a form, and at rest, i.e., within the data store in which it resides.

In light of this, any software that handles PHI should use strong encryption standards, such as:

  • Transport Layer Security (TLS – 1.2 or above): for secure transmission of PHI in email and text communications. 
  • AES (Advanced Encryption Standard) 256: the preferred encryption method for data storage as per HIPAA security standards, due to its strength.

3. Access Controls and User Authentication

One of the key threats to the privacy of patient data is access by unauthorized parties. This could be from employees within the organization who aren’t supposed to have access to PHI. In some, or even many, cases, this may come down to lax and overly generous access policies. However, this can result in the accidental compromise of PHI, affecting both a patient’s right to privacy and, in the event patient data is unavailable, operational capability. 

Alternatively, the exposure of PHI can be intentional. One on hand, it may be from employees working on behalf of other organizations, i.e., disgruntled employees about to jump ship to a competitor. More commonly, unauthorized access to patient data is perpetrated by malicious actors impersonating healthcare personnel. To prevent the unintended exposure of PHI, HIPAA compliant infrastructure, software and applications must support access control policies, such as:

  • Role-based access control (RBAC): the restriction of access to PHI based on their job responsibility in handling PHI, i.e.., an employee in billing or patient outreach. A healthcare organization’s security teams can configure access rights based on an employee’s need to handle patient data in line with their role in the company. 
  • Multi-factor authentication (MFA): this adds an extra layer of security beyond user names and passwords. This could include a one-time password (OTP) sent via email, text, or a physical security token. MFA is very diverse and can be scaled up to reflect a healthcare organization’s security posture. This could include also biometrics, such as retina and fingerprint scans, as well as voice verification.
  • Zero-trust security: a rapidly emerging security paradigm in which users are consistently verified, as per the resources they attempt to access. This prevents session hijacking, in which a user’s identity is trusted upon an initial login and verification. Instead, zero trust continually verifies a user’s identity.  
  • Robust password policies: another simple, but no less fundamental, component of user authentication is a company’s password policy. While conventional password policies emphasize complexity, i.e., different cases, numbers, and special characters, newer password policies, in contrast, emphasize password length. 

4. Audit Logs & Monitoring

A key HIPAA requirement is that healthcare organizations consistently track and monitor employee access to patient data. It’s not enough that access to PHI is restricted. Healthcare organizations must maintain visibility over how patient data is being accessed, transferred, and acted upon (copied, altered, deleted). This is especially important in the event of a security event when it’s imperative to pinpoint the source of a breach and contain its spread.

In light of this, HIPAA compliant software must:

  • Maintain detailed audit logs of all employee interactions with PHI.
  • Provide real-time monitoring and alerts for suspicious activity.
  • Support log retention for at least six years, as per HIPAA’s compliance requirements.

5. Automatic Data Backup & Disaster Recovery

Data loss protection (DLP) is an essential HIPAA requirement that requires organizations to protect PHI from loss, corruption, or disasters. With this in mind, a HIPAA-compliant software solution should provide:

  • Automated encrypted backups: real-time data backups, to ensure the most up-to-date PHI is retained in the event of a security breach.
  • Comprehensive disaster recovery plans: to rapidly restore data in case of cyber attack, power outage, or similar event that compromises data access.  
  • Geographically redundant storage: a physical safeguard that sees PHI. stored on separate servers in different locations, far apart from each other. So, if one server goes down or is physically compromised (fire, flood, power outage, etc.,) patient data can still be accessed. 

6. Secure Messaging and Communication Controls

For software that involves email, messaging, or telehealth, i.e., phone or video-based interactions, in particular, HIPAA regulations require:

  • End-to-end encryption: for all communications, as detailed above.
  • Access restrictions: policies that only enable those with the appropriate privileges to view communications containing patient data.
  • Controls for message expiration: automatically deleting messages after a prescribed time to mitigate the risk of unauthorized access.
  • Audit logs: to monitor the inclusion or use of patient data.

7. HIPAA Training & Policies

Even the most secure software can be compromised if its users aren’t sufficiently trained on how to use it. More specifically, the risk of a security breach is amplified if employees don’t know how to identify suspicious behavior and who to report it to if an event occurs. With this in mind, it’s prudent to look for software vendors that:

  • Offer HIPAA compliance and cyber safety awareness training for users.
  • Implement administrative safeguards, such as usage policy enforcement and monitoring.
  • Support customizable security policies to align with your organization’s compliance needs.

Shadow IT and HIPAA Compliance

Shadow IT is an instance of an application or system being installed and used within a healthcare organization’s network without an IT team’s approval. Despite its name, shadow IT is not as insidious as it sounds: it’s simply a case of employees unwittingly installing applications they feel will help them with their work. The implications, however, are that:

  1. IT teams are unaware of said application, and how data flows through it, so they can’t secure any PHI entered into it.
  2. The application may have known vulnerabilities that are exploitable by malicious actors. This is all the more prevalent with free and/or open-source software.

While discussing the issue of shadow IT in general, it’s wise to discuss the concept of “shadow AI” – the unauthorized use of artificial intelligence (AI) solutions within an organization without its IT department’s knowledge or approval. 

It’s easily done: AI applications are all the rage and employees are keen to reap the productivity and efficiency gains offered by the rapidly growing numbers of AI tools. Unfortunately, they fail to stop and consider the data security risks present in AI applications. Worse, with AI technology still in its relative infancy, researchers, vendors, and other industry stakeholders have yet to develop a unified framework for securing AI systems, especially in healthcare. 

Consequently, the risks of entering patient data into an AI system – particularly one that’s not been approved by IT – are considerable. The privacy policies of many widely-used AI applications, such as ChatGPT, state the data entered into the application, during the course of engaging with the platform, can be used in the training of future AI models. In other words, there’s no telling where patient data could end up – and how and where it could be exposed. 

The key takeaway here is that entering PHI into shadow IT and AI applications can pose significant risks to the security of patient data, and employees should only use solutions vetted, deployed, and monitored by their IT department. 

Best Practices for Choosing HIPAA Compliant Software

Now that you have a better understanding of how to evaluate software regarding HIPAA compliance, here are some best practices to keep in mind when selecting applications to facilitate your patient engagement efforts:

✔ Look for a BAA: quite simply, having a BAA in place is an essential requirement of HIPAA-compliant software. So, if the vendor doesn’t offer one, move on.

✔ Verify encryption standards: ensure the software encrypts PHI both at rest and in transit.

✔ Test access controls: choose HIPAA-compliant software that allows you to restrict access to PHI based on an employee’s role within the organization. 

✔ Review audit logging capabilities: HIPAA compliant software should track every PHI interaction. This also greatly assists in incident detection and reporting (IDR), as it enables security teams to pinpoint and contain cyber threats should they arise.

✔ Ensure compliance support: knowing the complexities of navigating HIPAA regulations, a reputable software vendor should provide comprehensive documentation on configuring their solution to match the client’s security needs. Better yet, they should provide the option of cyber threat awareness and HIPAA compliance training services. 

✔ Create a List of Software Vendors: combining the above factors, it’s prudent for healthcare organizations to compile a list of HIPAA compliant software vendors that possess the features and capabilities to adequately safeguard PHI.

Choosing HIPAA Compliant Software

Matching the right software to a company’s distinctive workflows and evolving needs is challenging enough. However, for healthcare companies, ensuring the infrastructure and applications within their IT ecosystem also meet HIPAA compliance standards requires another layer of, often complicated, due diligence. 

Failure to deploy a digital solution that satisfies the technical, administrative, and physical security measures required in a HIPAA compliant solution exposes your organization to the risk of suffering the repercussions of non-compliance. 

If select and deploy the appropriate HIPAA compliant software, in contrast, your options for patient and customer engagement are increased, and you’ll be able to include PHI in your communications to improve patient engagement and drive better health outcomes. Schedule a consultation with one of our experts at LuxSci to discuss whether the software in your IT ecosystem meets HIPAA regulations. and how we can assist you in ensuring your organization is communicating with patient and customers in a HIPAA compliant way.

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.

Integrating HIPAA Compliant Email with EHR Systems

With digital healthcare here to stay, today’s providers, payers and suppliers are making increasing use of Electronic Health Record (EHR) systems for more connected care – and better health outcomes.

However, while EHR systems help increase the speed and efficiency at which care can be delivered to patients, healthcare companies must still consider the security of electronic protected health information (ePHI) throughout the process, especially when it comes to communicating sensitive data with patients, customers, and other organizations. 

Fortunately, integrating an EHR system with a HIPAA compliant email service provider (ESP), like LuxSci, offers a secure way to engage with your patients, while leveraging – and protecting – the wealth of information within EHR systems to personalize communications.

In this post, we discuss the benefits of integrating EHR systems with a HIPAA compliant email platform, as well as several use cases made possible by bringing these two powerful solutions together.

What is an EHR System?

An EHR system is a platform used by healthcare companies to store and manage their patient’s digital data, including PHI. In providing a digital repository for a patient’s medical history, including diagnoses, prescribed medication, lab results, and other data related to their healthcare journey, EHR systems enable organizations to access, update, and share patient data more quickly and efficiently.

As EHR systems have steadily replaced paper-based records, namely, after the HITECH Act was enacted in 2009, which incentivized EHR adoption, healthcare companies are better able to access and share PHI across different environments, greatly enhancing the coordination and cooperation of providers, payers, and suppliers.

Why Should You Integrate EHR Systems with a HIPAA Compliant Email Platform?

Let’s discuss the key benefits of integrating your EHR Systems with a HIPAA compliant email platform:

Secure ePHI Transmission

When the sensitive data in EHR systems is sent out to patients and other healthcare providers and organizations, it must be encrypted, as per HIPAA regulations to safeguard it from exposure. That way, even in the event of a security breach, it will be unreadable to malicious actors, preserving the privacy of patients and customers. In light of this, HIPAA compliant email delivery platforms emphasize strong encryption capabilities to ensure sensitive patient data is always encrypted during transmission.

LuxSci’s SecureLine encryption technology employs automatic, flexible encryption, which applies the appropriate encryption standard depending on the recipient’s email security posture and infrastructure, making sure emails are always encrypted in transit. 

HIPAA Compliant Patient Engagement Campaigns

Healthcare organizations are often reluctant to include the patient data stored in their EHR systems for fear of accidental exposure – and violating HIPAA regulations as a result. In addition to encryption, LuxSci provides other HIPAA-mandated security features, such as access control capabilities, to maintain precise control over who can access patient data, and audit logging, to track access to ePHI. Perhaps most importantly, LuxSci provides you with a Business Associate Agreement (BAA): a legal document, and key pre-requisite for HIPAA compliance, that clearly establishes its responsibilities in safeguarding the ePHI that originates in your EHR systems. 

With these security capabilities in place, healthcare providers can confidently incorporate patient and customer data from their EHR systems into their outreach efforts, using ePHI to personalize emails accordingly to maximize engagement and improve communications.

Automated Secure EHR-Driven Communication

EHR systems facilitate automated healthcare workflows, including for clinical or administrative events that require effective communications, such as appointment scheduling, a patient diagnosis, or test results becoming available, automatically triggering follow-up actions, including updating patient care plans, generating invoices, sending outbound emails. In addition to facilitating consistency and coordination between the various companies involved in a patient’s healthcare journey, it reduces the amount of required manual work, lowering each organization’s administrative overhead. 

LuxSci’s suite of HIPAA compliant, secure communications tools aid in the enhanced efficiency and productivity of EHR systems by streamlining digital communication across multiple channels. LuxSci Secure High Volume Email can automatically send personalized, HIPAA-compliant messages triggered by EHR events. Similarly, LuxSci Secure Text allows companies to notify patients via SMS, as per the situation or patient preferences. LuxSci’s Secure Forms, meanwhile, simplifies onboarding and consent processes by pre-filling web forms with EHR data, eliminating the need for manual input paperwork and manual entry.

Common Email and EHR Integration Use Cases

Integrating your EHR system with a HIPAA compliant email solution, like LuxSci, opens the door for a wide variety of enhanced patient engagement opportunities. Let’s explore some of the most valuable use cases for EHR integration below.

  • Appointment Confirmations and Reminders: companies can create EHR-driven workflows that send out an email confirmation as soon as an appointment is scheduled. Similarly, automated email reminders and text messages can be scheduled to go out a set number of days before the patient’s appointment, lowering the chance of a no-show.
  • Pre-Visit Instructions: when appropriate, tailored preparation instructions can be scheduled to be sent out by email before the appointment, according to the nature of the appointment and other relevant patient data.
  • Follow-Up Care Guidance: by the same token, an EHR event can be set up to send out personalized after-care advice, sourced from care plans or notes stored in the EHR system.
  • Test Results: an email or text can be triggered as soon as a patient’s lab results become available; this could be in the form of an alert to contact their provider to collect the results or a summary alongside a secure link to a portal for full access.
  • Preventive Screening Reminders: EHR data can be used to identify patients due for screenings, immunizations, or chronic care follow-ups.
  • Preventative Care: sending patients advice and recommendations relevant to their condition, based on ePHI stored in their healthcare provider’s EHR.
  • Early Detection Self-Assessments: EHR-driven emails can be used to send patients personalized risk assessments designed to detect early warning signs of conditions such as diabetes or cancer, based on ePHI like age, lifestyle factors, or family history.
  • Feedback Collection: healthcare organizations can schedule feedback to be collected from patients, e.g., surveys, questionnaires, etc, to measure patient satisfaction and identify key areas of improvement.

email deliverability

What is Email Deliverability?

Email deliverability refers to the ability of emails to reach recipients’ inboxes successfully without being filtered into spam folders or blocked entirely by email service providers. This metric involves the entire journey an email takes from sender to recipient, including authentication protocols, sender reputation, content quality, and recipient engagement patterns. For healthcare organizations managing patient communications, provider networks, and supplier relationships, understanding email deliverability is highly important given the sensitive nature of healthcare data and the need for reliable communication channels.

How Email Service Providers Filter Messages

Email service providers use sophisticated algorithms to evaluate incoming messages and determine their appropriate destination. These systems analyze multiple factors simultaneously, including sender authentication records, message content, sending patterns, and recipient behavior. The filtering process occurs in real-time, with providers like Gmail, Outlook, and Yahoo applying machine learning models trained on billions of email interactions to identify potential spam or malicious content. Authentication plays a large role in this filtering process. Providers verify sender identity through SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) records. Healthcare organizations without properly configured authentication often find their appointment reminders, lab results, or billing communications relegated to spam folders, disrupting patient care workflows and administrative processes.

Sender Reputation and Its Impact on Healthcare Communications

Sender reputation functions as a digital credit score for email domains and IP addresses, influencing whether healthcare organizations can reliably reach patients, providers, and business partners. Email service providers maintain reputation databases that track sending behavior, bounce rates, spam complaints, and recipient engagement over time. A single domain or IP address with poor reputation can affect email deliverability across an entire healthcare network. Healthcare entities take on reputation challenges due to the nature of their communications. Patient appointment reminders sent to outdated email addresses generate high bounce rates, while automated billing notifications may receive spam complaints from recipients who forgot they subscribed to such communications. These factors can gradually erode sender reputation, making it increasingly difficult to reach patients with time-sensitive medical information.

Protocols for Healthcare Email Deliverability Security

Modern email deliverability depends heavily on proper implementation of authentication protocols that verify sender identity and prevent email spoofing. SPF records specify which mail servers are authorized to send emails on behalf of a domain, while DKIM adds cryptographic signatures to verify message integrity. DMARC ties these protocols together by instructing receiving servers how to handle emails that fail authentication checks. Healthcare organizations must configure these protocols carefully to avoid authentication failures that could block legitimate patient communications. A misconfigured SPF record might prevent appointment confirmation emails from reaching patients, while improper DKIM setup could cause lab result notifications to be filtered as spam. These authentication failures can have serious implications for patient care, particularly when dealing with urgent medical communications or time-sensitive treatment instructions.

Content Quality and Compliance Considerations

Email content quality directly affects email deliverability, with providers using advanced algorithms to evaluate message structure, language patterns, and formatting for spam indicators. Healthcare organizations must balance informative content with deliverability requirements, ensuring that medical communications reach their intended recipients without triggering spam filters. This balance becomes particularly challenging when dealing with complex medical terminology, prescription information, or insurance-related content that may resemble spam to automated filtering systems. HIPAA compliance adds another element of complexity to healthcare email content, as organizations must protect patient information while maintaining effective communication channels. Emails containing protected health information require extra security measures and careful content formatting to avoid both compliance violations and deliverability issues. The challenge is in creating compliant, informative communications that also pass through increasingly sophisticated spam filters.

Email Deliverability Performance

Tracking email deliverability metrics provides healthcare organizations with the data needed to identify and address communication issues before they impact patient care or administrative operations. Key metrics include delivery rates, bounce rates, spam complaint rates, and inbox placement percentages across different email providers. These metrics help organizations understand how their communications perform across various platforms and identify potential problems with specific communication types or recipient segments.

Healthcare organizations should establish monitoring systems that track deliverability performance across different communication channels, including patient portal notifications, appointment reminders, billing communications, and provider-to-provider messages. This approach helps identify patterns that might indicate authentication issues, content problems, or reputation concerns that could affect the organization’s ability to communicate effectively with patients and business partners.
