How to Secure SMTP Email Delivery with TLS

hands on a keyboard sending secure email

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.

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.

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.

What is the Meaning of Patient Engagement?

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.

LuxSci Digital Patient Engagement

Overcoming Barriers To Successful Digital Health Engagement

Effective patient engagement is increasingly becoming a top priority for many healthcare organizations  – and for good reason.

First and foremost, the more a patient or customer is engaged in their healthcare journey, the better their health outcomes and quality of life. With increased communication and engagement, patients are more likely to have potential conditions diagnosed sooner, take preventative measures to prevent illnesses, and educate themselves on ways to manage and improve their health. 

However, the benefits don’t end there and aren’t restricted to the patient. Engaged patients pay bills faster, are more open to new products and services, and report higher levels of satisfaction with the companies that contribute to their health and well being. For healthcare providers, payers, and suppliers, this results in higher revenue, more opportunities for growth, and the attainment of long-term organizational goals. 

Digital Patient Engagement Is Easier than Ever 

Fortunately, advances in technology and their rapid adoption by patients and customers (expedited by the COVID-19 pandemic) have made it easier for healthcare organizations to achieve successful digital interactions and engagement. Healthcare companies have more tools and channels than ever before to help conduct personalized engagement campaigns that meet patients on their terms, making it easier to capture their attention. Secure email takes it even further with the ability to include protected health information in messages to personalize

Despite these advancements, however, there are still several barriers that prevent healthcare companies from engaging with patients and reaping the associated benefits. Fortunately, each barrier can be overcome to help patients and customers feel more included and instrumental in their healthcare journeys.

With this in mind, this post discusses the main barriers to digital patient engagement and how to overcome them to drive better healthcare outcomes for your patients and growth for your organization. 

The Main Barriers To Digital Health Engagement

The four key barriers to digital health engagement that we’ll explore in this post are as follows:

    1. Low Health Literacy

    1. Privacy And Security Concerns

    1. Age And Cultural Differences

    1. Lack Of Personalization

Let’s review each barrier in turn, while offering potential solutions that will contribute to greater digital health patient engagement for your healthcare organization. 

Low Health Literacy

The first barrier to successful digital health patient engagement is your patients having insufficient health or medical knowledge. Healthcare is laden with terminology, including medical conditions, pharmaceuticals, the human anatomy, and many patients simply don’t understand enough to get more involved with their healthcare journey.  Worse still, few patients will admit they don’t understand, as people are often embarrassed at their lack of knowledge.


Consequently, if your digital health patient engagement campaigns are heavy with medical jargon and lack personalization, patients won’t act on the information to drive better outcomes.

Solution: Create Educational Health Content

Develop simple educational resources for your patients that apply to their unique needs and condition. This will help them understand their state of health and make better sense of subsequent communications they’ll receive from you and their other healthcare providers.

This educational content could be in the form of periodic email newsletters, giving you a great reason to keep in touch with your patients. Alternatively, they could take the form of blog posts or articles on a patient portal, which could be supported by an email marketing campaign to let patients know about the article. In helping to increase your patients’ health literacy, you offer additional value as a healthcare provider, payer or supplier.


Additionally, keep the medical jargon in your email communications and other patient engagement channels to a minimum. Empathize with the fact that some patients won’t understand as much as others when it comes to healthcare provision and explain things as plainly as possible. 

Data Privacy And Security Concerns

Unfortunately, due to its sensitivity and critical nature patient data, i.e., protected health information (PHI) is highly prized by cybercriminals. Subsequently, there have been many high-profile healthcare breaches, such as the Change Healthcare breach, in early 2024, which affected 100 million individuals, that make patients increasingly wary about sharing health-related information via email, text, or other digital communication channels.


That said, their wary attitude is the right one to adopt, but not at the expense of enhancing engagement and improving their health outcomes. 

Solution: Invest In HIPAA Compliant Communication Tools

Ensure that the digital tools you use to engage with patients possess the security features required for HIPAA compliance. The  Health Insurance Portability and Accountability Act  (HIPAA) provides a series of guidelines that healthcare organizations must comply with to best safeguard PHI. Consequently, solutions that promote their commitment to HIPAA compliance, such as LuxSci, will understand the privacy, security, and regulatory needs of healthcare companies and have developed their tools accordingly.


Most importantly, a HIPAA compliant vendor will sign a Business Associates Agreement (BAA), the legal documentation that outlines your respective responsibilities regarding the protection of PHI. Safe in the knowledge that the patient data under your care is secure, you can concentrate your efforts on personalizing your digital communication campaigns for maximum effect. 

Age And Cultural Differences

Ineffective patient engagement efforts (or a complete lack of engagement, altogether) can reinforce cliches about the use of digital tools within particular patient groups. The reality, however, is that many healthcare organizations don’t account for age differences and channel preferences in their patient engagement strategies.


Subsequently, if you only engage with patients on a single communication channel, you risk alienating others because it’s not their medium of choice.  

Solution: Adopt a Multi-Channel Engagement Strategy

Instead of focusing on one communication medium, diversify your approach and adopt a multi-channel engagement strategy. This could encompass email, SMS, and phone outreach, for instance. This covers the more proverbial bases and gives you a chance to engage with patients on their preferred terms.

Lack Of Personalization

One of the main reasons that healthcare organizations fail to engage with their patients is that they adopt a “one-size-fits-all” approach, attempting to craft communications that appeal to as many people as possible. Unfortunately, this has the opposite of the desired approach, not connecting anyone in particular and engaging few patients as a result.  

Solution: Personalize Your Patient Engagement Campaigns with PHI

With a HIPAA compliant solution, you can use PHI to personalize patient engagement, leveraging their health data to craft messaging that reflects their specific condition, needs, and where they are along their healthcare journey. PHI also can be used to segment patients into subgroups, grouping them by specific commonalities such as age, gender, health condition, and lifestyle factors.
