Email marketing can be a powerful tool for healthcare organizations, but it requires careful planning and execution because of HIPAA compliance requirements. In this blog post, we will discuss email marketing best practices to help healthcare marketers achieve their goals.

1. Define Your Campaign Goals

The success of any email marketing campaign depends on the goals you want to achieve. However, because healthcare organizations are often not selling products to their patients, marketers can be confused about how to set measurable goals for their campaigns that aren’t tied to revenue generation.

Healthcare marketers want to use email marketing campaigns for various purposes, including patient engagement, education, and retention. Some possible objectives of your campaigns could be:

New patient acquisition
Re-engaging lapsed patients
Spreading awareness about vaccines, treatments, or medical conditions
Increasing treatment or medication adherence
Collecting survey responses or patient-reported outcomes

All of these campaign objectives will correlate with different metrics. Identifying the campaign goal and the corresponding metrics you need to track is critical before selecting the audience and crafting the content.

2. Select Your Audience

Gone are the days of sending giant email blasts to your entire contact list. The best email marketers are creating highly targeted campaigns for specific audiences. Healthcare marketers using patient data in their audience targeting efforts are at an advantage. They can use patient information to create distinct audience segments. Targeting a patient population with common attributes makes it easier to craft a relevant message to drive clear results. For example, marketers can create more relevant campaigns when they can divide their patient population into subgroups based on shared characteristics like diagnoses, risk factors, and demographic data.

3. Personalize Your Content

Once you have clearly defined your goal and your audience, it’s essential to use personalization techniques to craft relevant messaging. Healthcare consumers expect more personalization from their providers and want to receive messages that tie into their past experiences. Generic, irrelevant messaging is more likely to annoy patients than get them to act. Healthcare marketers are lucky to have a wealth of data points to use in their messaging, but they must be aware of patient privacy and take steps to secure their messaging. When you have taken the appropriate steps to secure patient data, including protected health information in email messages is possible. This improves the patient experience and makes it easier for healthcare marketers to achieve their objectives.

4. Use A Clear Call-to-Action

Your emails should include a clear call-to-action (CTA) that encourages your audience to take the desired action. These actions may include scheduling an appointment, downloading a resource, logging into a patient portal, filling out a survey, or contacting your organization. Ensure that your CTA is prominent, stands out from the rest of your content, and ties back to the goal of your campaign. Most importantly, implement appropriate tracking technologies so you can see how many email recipients followed through on the CTA.

Don’t include too many calls to action in one message! Including multiple prompts may confuse the recipient and make it more difficult for your team to understand how the campaign performed.

5. Review Your Data

Finally, it’s essential to monitor your email metrics to evaluate the success of your campaigns. Some key metrics may include open rates, click-through rates, surveys completed, successful logins, appointments scheduled, and other relevant metrics that tie back to your goals. Use this data to refine your email marketing strategy, trigger follow-up campaigns and marketing activity, and optimize future campaigns. Use APIs or webhooks to ensure your email campaign statistics are tied into marketing dashboards to get a holistic view of how your campaigns are performing.

6. Choose an Email Marketing Platform Designed for Healthcare

Finally, to use the tactics recommended above, it’s necessary to use a HIPAA-compliant email marketing platform. Segmenting audiences and personalizing content requires the use of protected health information. Therefore, it must be secured in compliance with HIPAA. You must select a platform that can protect data both at rest and in transit to utilize the power of your data fully.

Understanding Business Associate Agreements (BAAs) and Shared Responsibility

September 9, 2025
Pete Wermter

Modern-day healthcare organizations rely on a growing array of partners and vendors to provide them with the tools they need to effectively serve patients and customers.

However, while new digital solutions and healthcare ecosystems often result in greater productivity and efficiency, they also increase the number of third parties a company must communicate with and share protected health information (PHI), requiring a business associate agreement (BAA). Unfortunately, this increases the risk of PHI being exposed, as it increases a healthcare organization’s supply chain network and the number of external organizations with access to their data, significantly raising the risk of a security breach.

This is where the concept of shared responsibility comes in.

In this article, we explore the shared responsibility model for data security, explaining the concept, the role of a BAA in shared responsibility, and why healthcare companies need to know how it works and where it factors into their HIPAA compliance efforts.

What Is The Shared Responsibility Model?

Shared responsibility is a core data security principle that divides the responsibility for protecting data between a company that collects the data and a vendor that supplies the infrastructure or systems used to process said data.

The shared responsibility model grew in prominence as more companies moved to cloud-based environments and applications. In the past, when companies kept their systems and data onsite, they had more control over who could access their data and, subsequently, a better ability to mitigate data security risks.

However, in adopting cloud-based infrastructure and applications, companies have to process and store their data in the cloud – often in shared infrastructure with other vendors using the same cloud – which consequently shifts some of the responsibility of information security to the cloud service provider (CSP) itself. This marked a profound shift in the way data was handled, transmitted, and stored – necessitating an evolved approach to data security.

This fundamental shift in the way companies consume infrastructure and use apps ushered in the shared responsibility model: Where the cloud vendor provides the infrastructure or application, including HIPAA compliant and high secure environments, but it’s still the responsibility of the client to configure and use it securely.

Business Associate Agreements (BAAs) and Shared Responsibility

By detailing the respective responsibilities of healthcare companies or Covered Entities (CEs) and their vendors or Business Associates (BAs) in securing PHI, a Business Associate Agreement is a prime example of shared responsibility.

For example, the Business Associate shoulders the responsibility of providing the data safeguards required by HIPAA to secure patient data, such as infrastructure, encryption, audit logging, and even physical onsite security.

The Covered Entity, meanwhile, is responsible for conducting risk assessments, defining access control policies and processes, configuring services accordingly, workforce training, and continuous monitoring.

Additionally, both parties have the obligation to report security incidents to each other, as well as being independently accountable to the U.S. Department of Health and Human Services (HHS).

Why Shared Responsibility Is Essential for HIPAA Compliance

For healthcare companies, having a firm grasp of the shared responsibility model for safeguarding and securing PHI, and how they fit within your overall security posture is essential (for two key reasons).

Security Gaps

Firstly, clearly understanding the shared responsibility decreases the likelihood of security gaps. If CEs are under the impression that the vendor handles all aspects of data security, they won’t be as vigilant. They’ll be less inclined to configure services, educate their staff accordingly, pay appropriate attention to vendor security alerts, etc.

But the same is also true for BAs: If they assume their client does most of the heavy lifting in securing the data disclosed to them, they could be remiss in their duties to protect it. Without shared responsibility, each side simply assumes the other is covering a safeguard, opening the door for security gaps that malicious actors can exploit.

Fortunately, by detailing both parties’ (CEs and BAs) responsibilities and liabilities regarding data protection, a BAA removes this ambiguity and, more importantly, reduces the risk of security gaps. It’s critical to know the details and work with vendors building products for compliance versus implementing a tick-box approach to compliance that places too much burden on the CE.

Covered Entities (CEs) Are Ultimately Accountable

Subsequently, the second reason why it’s essential for CEs to understand the shared responsibility model, and increase their cybersecurity readiness accordingly, is that it’s the CE that’s ultimately held accountable for data breaches.

Mistakenly thinking that a BAA automatically makes them compliant may result in healthcare companies underinvesting in training, monitoring, and incident response. Conversely, understanding that even with a BAA in place, they’re the ones primarily accountable for protecting PHI gives them a greater sense of urgency to properly implement HIPAA compliant security measures.

The Covered Entity’s Role Within Shared Responsibility

Let’s look at the ways that healthcare companies have to hold up their end in the shared responsibility model.

Choose Compliance-Conscious Vendors

First and foremost, companies have to choose the right vendors to supply them with HIPAA compliant services and solutions.

Look for companies that market themselves as HIPAA compliant and display a detailed understanding of HIPAA requirements, particularly the HIPAA Security Rule. Do your due diligence and perform deeper dives on potential vendors, researching their stated security features, reviews from existing clients, whether they have certifications like HITRUST – and if they’ve been involved in any data breaches.

Naturally, a core prerequisite of being a HIPAA compliant vendor is being willing to sign a BAA, so you can immediately rule out any vendors not willing to do so. For instance, some healthcare companies may assume they can use widely adopted solutions such as SendGrid, Mailchimp, but they don’t offer a BAA.

Once you’ve confirmed a vendor offers a BAA, look through it to establish its terms and determine if it covers the services you’re interested in.

Configuration

Another core component of shared responsibility is comprehensive configuration management. While the BA’s responsibility is to provide a secure solution that satisfies HIPAA requirements, it’s the CE’s responsibility to configure it securely to fit within their IT ecosystem.

Features that often require configuration include:

Access control: Role-based access, Zero Trust, Multi-Factor Authentication (MFA).
Encryption settings: Enabling encryption, choosing encryption type, enforcing forced TLS, enabling storage encryption.
Feature restrictions: Disabling default configurations that enable integration with non-compliant tools.
Audit logging: Enabling audit logging and configuring log formats.
Retention settings: How long to retain audit logs and who is permitted to review them.

Finally, establishing a patch management strategy, i.e., when and how your organization applies software updates, is an important element of configuration. While the vendor must release updates to fix security vulnerabilities discovered in their solutions, it’s up to healthcare companies to deploy the patches.

Training

Regardless of how many security features a vendor bakes into their solutions, once deployed by a healthcare company, the tool is only as secure as the practices of their least security-conscious employee. Consequently, companies must train their staff on how to properly use a solution to process protected health information and sensitive data. The more an employee is required to handle PHI, the more thorough and frequent their training should be.

Key aspects of comprehensive cybersecurity training include:

Common cyber threats: what the most prevalent cyber threats are and how to recognize them.
Incident response: how to report a suspected security incident, i.e., who to contact and when.
Specific solution training: how to securely use systems that process PHI
Scope awareness: knowing which services within your organization’s IT ecosystem are HIPAA-compliant and which are not

Reporting

Although both healthcare companies and BAs have notification obligations to the HHS in the event of a data breach involving PHI, it’s the CE that bears most of the investigative burden.

Firstly, while a BA may report a security incident, it’s the CE’s responsibility to conduct a risk assessment to determine the probability of compromise of PHI, assess risk, and determine whether an official notification of a breach to HHS is necessary.

Secondly, BAs must notify the CE without unreasonable delay and no later than 60 days after discovery. Although BAs often wait to complete internal investigations before notifying the CE, the CE’s 60-day clock starts upon the BA’s discovery, not upon the BA’s report. Therefore, BA delays can create compliance risks for the CE.

To prevent this, where possible, you can include stricter contractual reporting timelines in the BAAs. This constantly keeps your company in the loop, ensuring you have sufficient lead time to complete your own investigations and your HIPAA-regulated deadlines.

Signing a BAA Does Not Automatically Make You HIPAA Compliant

August 26, 2025
Pete Wermter

For healthcare organizations, choosing the right product and service vendors is essential for achieving HIPAA compliance. One of the key prerequisites of a HIPAA-compliant vendor is the willingness to sign a Business Associate’s Agreement (BAA): a legal agreement that outlines both parties’ responsibilities and liabilities in securing protected health information (PHI).

However, despite what some healthcare organizations have been led to believe, simply signing a BAA with a vendor doesn’t guarantee your use of their product or service will be HIPAA-compliant. In reality, a BAA is just the beginning, and there are several subsequent actions both healthcare organizations and their supply chain partners must take to ensure the compliant use of PHI, especially over communications channels like email.

With this in mind, this post explores some of the reasons why signing a BAA on its own doesn’t ensure the security of PHI and protect your organization from HIPAA violations.

Business Associate Agreements (BAAs) Explained

As touched upon above, a BAA is a legally-binding document established between a covered entity (CE), i.e., healthcare organizations, and a business associate (BA), i.e, any company that handles PHI in providing a CE with products or services. For a BA to handle patient or customer data on behalf of a CE, following HIPAA regulations, there must be a BAA in place.

A BAA details:

Each party’s roles, responsibilities, and liabilities in securing PHI.
The permitted uses of PHI by the BA and, conversely, restrictions on any other use.
The BA’s responsibilities in implementing appropriate administrative, technical, and physical security measures to best protect PHI.
The BA’s obligations to report any unauthorized use, disclosure, or breach of PHI.
That the BA is required to assist with patient rights support, i.e., data access, amendments, and accounting of disclosures, when appropriate.
The BA’s obligations in making records available for audits or investigations.
The CE’s right to terminate the contract if the BA fails to fulfil their obligations in safeguarding PHI.

Additionally, if a BA employs a third-party company, i.e., a subcontractor, that will have access to a CE’s PHI, they are required to establish a BAA with that company. This then makes the subcontractor a “downstream BA” of the CE, and subject to the same obligations and restrictions placed on the original BA. This ensures the security protections mandated by HIPAA flow down the entire chain of custody for sensitive patient and customer data.

Compliance Considerations After Signing a Business Associate Agreement (BAA)

Now that we’ve covered what a BAA is and the role it plays in ensuring data privacy, let’s move on to exploring some of the key things you have to do following the singing of a BAA to ensure HIPAA compliance.

1. Both Parties Must Implement HIPAA-Required Data Risk Mitigation Measures

First and foremost, while a BAA details each party’s respective responsibilities in implementing measures to protect PHI, both still actually need to implement those required security features to achieve HIPAA compliance.

The measures required under HIPAA’s Security Rule, including encryption and access control, are designed to mitigate and minimize the impact of data breaches. So, if a company suffers a security breach and later audits show the required security policies and controls were not in place, they would be subject to the consequences of HIPAA violations, including fines and reputation damage.

Also, while a BAA stipulates that the BA is responsible for implementing the HIPAA-required safeguards for the PHI under their care, it doesn’t specify exactly which security measures they must implement. Subsequently, that’s left to the BA to interpret based on their understanding of HIPAA requirements, and how they conduct their required risk assessments.

For example, if you have a BAA with your email services provider, that alone may not be enough to keep your company or organization HIPAA compliant. That’s because the provider may not have the security measures your organization needs, and instead have a carefully worded BAA that will leave you vulnerable.

Let’s say your email marketing service provider is a “semi-HIPAA compliant” provider. In these cases, they may not offer email encryption, or the necessary access control measures your organization needs to send PHI and other sensitive information safely. The so-called HIPAA compliance may be limited only to data stored at rest on their servers only.

In short, although a BAA outlines each party’s commitment to securing data, both parties still have to follow through on implementing risk mitigation measures. Additionally, though a healthcare company has its BA’s assurances that they’ll have the appropriate safeguards in place, CEs often only have limited visibility into its ongoing security posture. As a result, asking the right questions and working with a proven HIPAA compliant provider are critical steps healthcare organizations must take to ensure full compliance.

2. CEs Must Stick to “In-Scope” Services

While a BA may provide a CE with a range of services, many limit the coverage of their BAAs to particular “in-scope” services. As a result, if a healthcare organization were to use a service outside the coverage of the BAA, i.e., an “out-of-scope” service, they’d risk exposing patient data and incurring HIPAA violations.

And, even when a service is in-scope, the BA is still required to configure it properly for it to be compliant. These configurations could include:

Enabling encryption
Establishing access control
Activating multi-factor authentication (MFA)
Turning on audit logging

With this in mind, it’s crucial to ensure that the “complete” service or tool – not just a part of it – is covered by a BAA before using it to process PHI. Similarly, check the terms of your BAA for configuration or security best practices that offer guidance on fully HIPAA compliant use, and make sure your responsibilities as a CE are 100% clear.

3. Staff Must Be Trained to Securely Handle PHI

Another key reason that signing a BAA doesn’t automatically result in HIPAA compliance is the likely need for both parties to educate their staff on how to securely handle sensitive data, such as PHI.

Firstly, as discussed above, only some of the services offered by a BA may be covered by its agreement. Subsequently, a healthcare organization’s employees need to be sufficiently trained on the use and disclosure of PHI, namely, the services in which they’re permitted to process PHI and which, in contrast, services are non-compliant.

By the same token, as well as implementing the stipulated safeguards, BAs are responsible for training their workforce on how to use and, where appropriate, configure them. This will help ensure the limited, correct use and disclosure of PHI as allowed by the BAA.

4. Reporting Requirements

A BAA stipulates that a BA must notify the CE in the event of improper or unauthorized use of PHI. More specifically, this includes:

Reporting immediately any use or disclosure not permitted by the terms of the BAA.
Notifying the CE of security incidents resulting in the potential exposure of PHI.

However, the commitment to reporting in the BAA and the ability to deliver on that commitment are two different things entirely. Firstly, the BA must implement the policies and infrastructure that allow for timely incident reporting. This includes conducting risk analysis, implemeting continuous monitoring, and developing a robust incident response plan.

Additionally, a key aspect of prompt, comprehensive reporting includes the BA ensuring that their staff are sufficiently trained to detect and report security events. As part of their training on the secure handling of PHI, a BA’s employees must be able to recognize common security issues and threats, such as improper email configurations and phishing attempts, and how to report them.

5. Subcontractor BAAs

While CEs must sign BAAs with their BAs for the compliant use and disclosure of PHI, they don’t have to sign such agreements with any subcontractors the BA may employ. Instead, it’s the responsibility of the BA to enter into their own business associate agreements with their subcontractors. As a result, the original security obligations are passed all the way down the data’s chain of custody.

While a CE can take certain measures to enforce this, such as requesting proof of subcontractor BAAs – or even the ability to review subcontractors before beginning engagement – ultimately, they have little control over their security postures. Ultimately, this means that they have to trust that the original service BA does their due diligence in selecting security-minded subcontractors, with the right PHI safeguards in place.

How Hypersegmentation Drives Greater Healthcare Marketing Engagement

August 20, 2025
Pete Wermter

In healthcare marketing, effective engagement is crucial. It’s imperative that healthcare providers, payers, and suppliers know how to connect with their patients and customers, keeping them aware of all aspects of their healthcare journey – and empowering them to participate as much as possible.

This is where segmentation comes in.

Instead of sending out healthcare marketing email communications that appeal to as many people as possible, segmentation enables healthcare companies to appeal to specific individuals or groups. It opens the doors for scenarios in which patients and customers see a message in their inbox and think, ‘this message is for me’.

With that goal in mind, this post explores use cases and best practices in segmentation, why it’s so important for healthcare companies, and different ways that marketers can segment their audiences for optimal patient and customer engagement.

What is Segmentation?

Segmentation is the process of dividing your contact list, or audience, into smaller groups based on shared data, including protected health information (ePHI) characteristics. This could include demographics (age, gender, geographic location, etc.), medical conditions, risk factors, behaviors, and so on.

Why Segmentation is Essential in Healthcare Email Marketing

For healthcare organizations, segmentation is a highly effective, and essential, strategy for sending patients and customers personalized email messaging. Personalized emails are more relevant to the recipient, which greatly increases the chance of them capturing their attention and subsequent engagement.

This allows healthcare companies to successfully achieve the objective of their email campaigns, whether that’s reducing the number of appointment no-shows, increasing adherence to care plans, securing payments, or boosting sign-ups or sales. More importantly, patients and customers are more involved in their healthcare journey, staying on top of upcoming appointments, receiving applicable advice and recommendations, and becoming aware of products and services that may prove beneficial to their health, improving overall outcomes.

Additionally, dividing audiences into distinct groups gives healthcare organizations invaluable insights into the behaviour and needs of different segments at different stages of the healthcare journey.

For instance, an email campaign targeting a particular segment may reveal that they’re more likely to miss appointments than other groups. Similarly, segmentation may highlight that a certain high-risk group neglects to book recommended health screenings. Such insights enable healthcare providers, payers, and suppliers to improve their email engagement strategies, to drive more desirable outcomes and, ultimately more satisfied, loyal, and, above all, healthier patients and customers.

How Can Segmentation Aid HIPAA Compliance?

Another considerable benefit of segmentation for healthcare organizations is that it supports their HIPAA compliance efforts. Because segmentation necessitates setting precise rules that control which individuals receive particular emails, it greatly mitigates the risk of accidentally sending sensitive patient data to the wrong person.

Let’s say, for instance, that you want to conduct an email campaign targeting expectant mothers. By creating a segment comprised of pregnant patients or customers using the appropriate data field, you ensure that sensitive, pregnancy-related information is only sent to relevant parties. By reducing the likelihood of disclosing PHI to the wrong individuals, segmentation not only helps maintain regulatory compliance, but also preserves patient trust and confidence in your organization.

Different Ways to Segment Your Audience

Demographic Segmentation

This involves grouping individuals by shared demographic attributes such as:

Age
Gender
Location
Ethnicity
Education Level
Employment Status
Marital Status
Family Status
Socioeconomic Status (Income)
Spoken Languages / Preferred Language
Income
Insurance Coverage Type
Religious or Cultural Affiliations

Demographic information is a very powerful way to segment audiences to send them valuable, highly relevant information, for example:

Sending mammogram or prostate screening recommendations to women or men over a certain age.
Sending health alerts to people in a certain region or ZIP code in response to the emergence of a disease in their area (e.g., flu, a new COVID strain).
Making educational material easy to understand and informative.

Clinical Segmentation

Here, individuals are grouped according to medical criteria, such as:

Health conditions
Prescribed medications
Treatment plans
Recent surgeries or medical procedures
Recent lab test results
Hospitalization history
Vaccination status

This enables healthcare organizations to craft a wide range of specific communications that hone in on particular patients and customers, including:

Disease management and preventative care advice for people suffering from certain conditions, e.g, how diabetic patients can best monitor and manage their blood sugar.
Recovery guidance for post-operative patients.
Feedback requests for individuals on particular treatment plans, in an effort to optimize them.

Healthcare Journey Stage Segmentation

This divides individuals according to their position in their care journey within your organization.

For healthcare providers, new patients should receive onboarding materials, explanations of services and how to make the most of them, and similar materials that help them feel welcome and informed. Existing patients, meanwhile, can be further segmented into active, overdue (inactive), or high-risk groups – all of which have different needs and ways in which they should be communicated with:

Active patients: appointment reminders, educational materials, event and service recommendations, satisfaction surveys, etc.
Overdue and inactive patients: appointment or payment reminders, re-engagement communications, etc.
At risk patients: more frequent communications, care coordination messages, or support service referrals

Behavioral Segmentation

This method of segmentation is based on how recipients interact with emails or services, including:

How often they open emails.
If they click through on links.
If they use patient portals.
If they complete forms.
How often they attend scheduled appointments.

This segmentation empowers healthcare organizations to tailor the content type, frequency, and calls-to-action based on real engagement insights, and also carry out automated workflows based on each individual’s interaction with an email.

How Automated Workflows Boost Engagement for Healthcare Marketing Campaigns

August 13, 2025
Pete Wermter

Due to the fact that it’s simple, instantaneous, cost-effective, and nearly universally adopted, email is an essential part of all healthcare marketing engagement strategies. However, consistent, personalized email engagement – particularly at scale – can be challenging.

Fortunately, Automated Workflows offer a solution, allowing healthcare companies to deliver the right messages to the appropriate individuals at the right time, based on their individual engagement with emails..

In this post, we’ll explore the concept of Automated Workflows, the considerable benefits they offer healthcare companies, and the variety of ways they can be used to increase engagement and result in greater satisfaction and better healthcare outcomes for your patients and customers.

What Are Automated Workflows?

An Automated Workflow is a sequence of actions, known as’ Steps’ in LuxSci Secure Marketing, that a Contact (i.e., a patient or customer) moves through over time, based on a series of pre-defined rules or triggers.

Each Step is programmed to automatically perform a specific function, such as sending an email or updating a Contact, when certain conditions are in place. These conditions could include:

A Contact opening a message.
A Contact clicking through on a link.
A specified amount of time having elapsed..
A data update via an API call

By evaluating conditions to initiate the appropriate Step, Automated Workflows facilitate more timely, consistent, and personalized communication with Contacts (patients and customers ). As a result, healthcare companies can effectively harness Automated Workflows to develop dynamic, personalized email engagement journeys that adapt according to your patients and customers’ needs and prior interactions.

What Are the Benefits of Automated Workflows?

Let’s look at the various advantages that Luxsci Automated Workflows offer.

Reduced Administrative Workload

Arguably, the most significant benefit of Automated Workflows is the extent to which they lower the administrative burden of email engagement campaigns for healthcare organizations.

First and foremost, Automated Workflows eliminate the need for an employee to manually send your Contacts messages. As well as the manual effort, it removes a great deal of thought from the process – as someone isn’t required to remember to send an email.

By the same token, this reduces the scope for human error, preventing the possibility of an employee neglecting to send an important message, sending it to the wrong person, or worse, accidentally exposing patient data, i.e., electronic protected health information (ePHI).

The effort that Automated Workflows reduce is typically repetitive work that staff are glad to be free of, giving them additional time to focus on tasks that provide greater value and better contribute to better patient care and/or the customer experience.

Enhanced Scalability

The time saved by employing Automated Workflows increases with the size of your Contact List and the scale of your engagement campaigns. In fact, enterprise-scale campaigns, with volumes of hundreds of thousands to millions of emails, are only feasible through the use of automation.

Similarly, Automated Workflows enable healthcare organizations to run differing, personalized email campaigns aimed at unique patient or customer segments. As well as automatically sending each message at the appropriate time, they provide tracking capabilities to determine the outcome of each message.

Increased Consistency in Communication

Because Automated Workflows remediate the risk of emails going unsent, they facilitate more timely and consistent communications with patients and customers. This makes healthcare providers, payers, and suppliers appear more reliable and consistent, building trust and greater levels of satisfaction from Contacts. More importantly, recipients are better able to track what’s happening with their healthcare and assume a more proactive role overall healthcare journey..

Finally, creating an Automated Workflow requires healthcare organizations to carefully consider how they communicate with different Contact segments. Namely, the likely journey, or communication path, different types of Contacts take, i.e., information they need to know at a particular stage in their healthcare journey, the optimal order in which information needs to be presented, etc. This allows healthcare companies to become more in-tune with their patients’ and customers’ needs, enabling them to craft more valuable email communications that boost engagement.

Personalized Healthcare Engagement

Perhaps the most significant benefit of Automated Workflows is that they enable adaptive, personalized engagement for healthcare marketing and communications campiagns. Instead of manually tracking where each Contact is in a given engagement sequence, or worse, merely having to guess, you know precisely where they are. Consequently, you’re acutely aware of their needs and the exact nature of the emails you need to send them next.

This, in turn, enables more effective Contact nurturing, i.e, strengthening your organization’s connection with each individual. When at its most effective, this may allow you to anticipate your Contacts’ needs, enabling you to send them communications, such screening or testing recommendations, educational materials, or product and service suggestions, that support their healthcare journey and enhance their quality of care.

Automated Workflow Use Cases

Automated Workflows are a powerful tool for increasing healthcare marketing and communications engagement because they can be applied to a wide range of use cases. Let’s take a look at some of the most common and impactful ways email automation can be used by healthcare companies.

New Product Announcements: keeping patients and customers in the loop on your company’s latest offerings, as well as improvements to existing products and services that are likely to be of interest, based on their data and past actions.
Personalized recommendations: suggesting products or services based on the recipient’s past purchases or engagement history.
Re-Engagement Campaigns: Automated Workflows can also be used to reconnect with Contacts with whom engagement has waned or was never completely established, sending them personalized messages to encourage specific actions or reignite interest.
New Member Onboarding: welcoming new patients or customers with a structured series of emails that introduces your services, provides technical assistance (where applicable), details subsequent steps, and explains how to get the most value from your products or services.
Appointment Reminers and Follow-Ups: sending reminders, care instructions, medication adherence advice, or details on how to book subsequent appointments, for instance, after a patient visit.
Patient Education Campaigns: taking patients through a structured curriculum on managing their medical condition or required lifestyle changes to improve their health..
Preventative Care Communications: proactively sending reminders for screenings, check-ups, vaccinations, etc., based on PHI such as a patient’s age, gender, health condition or lifestyle risk factors.

Milestone Communications: sending personalized messages to acknowledge birthdays, enrollment anniversaries, and other pertinent dates. These can also be combined with preventative care communications, to send recommendations or other advice, based on the contact’s age, for instance.
Feedback Collection: acquiring patient and customer feedback by sending follow-up surveys a set amount of time after a visit, procedure, purchase, etc.

How Automated Workflows Work in LuxSci Secure Marketing

To round off this post, let’s take a deeper look at how Automated Workflows work within LuxSci’s Secure Marketing solution. LuxSci’s Automated Workflows enhance your organization’s HIPAA compliant healthcare marketing and email campaigns by giving you complete control of:

When each email is sent
Which Contacts receive particular communications according to their behavior, needs, and other PHI-based attributes
Which engagement path or branch a Contact takes based on their email actions

The Risks of Third-Party Email Integrations for Healthcare Companies

March 10, 2025
Pete Wermter

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

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

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

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

What Are The Risks of Third-Party Email Integrations?

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

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

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

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

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

How To Mitigate Email Integration Risk

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

Verify A Third-Party Vendor’s Security Practices

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

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

Business Associate Agreements (BAAs)

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

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

Encrypting PHI

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

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

Threat Intelligence

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

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

Developing An Incident Response Plan For Vendor-Related Breaches

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

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

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

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

Choose a HIPAA-Compliant Email Provider

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

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

Train Staff on Secure Email Communication Practices

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

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

What Makes a Platform HIPAA Compliant?

November 20, 2024
Erik Kangas

A platform becomes HIPAA compliant through a combination of security features, privacy controls, and administrative processes that protect patient information according to HIPAA regulations. No platform is inherently compliant—rather, compliance emerges from implementing required safeguards, obtaining a Business Associate Agreement, and configuring the platform HIPAA compliant settings to handle protected health information properly. Healthcare organizations must evaluate platforms based on these capabilities and implement appropriate security measures to maintain compliance.

Core Security Protections

To make a platform HIPAA compliant, entities must incorporate several fundamental security capabilities. Encryption protects data both during storage and transmission, preventing unauthorized access. Authentication systems verify user identities through methods like password requirements and multi-factor verification. Access controls restrict what information different users can view based on job roles and responsibilities. Audit logging creates records of who accessed information and what actions they performed. Backup systems maintain data availability while incorporating appropriate security protections. These features enable organizations to implement the safeguards required by the HIPAA Security Rule.

Vendor Agreement Framework

HIPAA compliant platforms provide Business Associate Agreements (BAAs) establishing vendor responsibilities for protecting healthcare information. These agreements define how the platform vendor handles protected health information and outlines security obligations. Platforms designed for healthcare use typically offer standardized BAAs as part of their service agreements. The agreement specifies which portions of the platform fall under compliance coverage, as some vendors exclude certain features or services. Organizations must obtain these agreements before storing any patient information on third-party platforms regardless of security features implemented.

Patient Data Privacy Mechanisms

Platforms supporting healthcare data incorporate privacy controls aligned with HIPAA requirements. Notice functionality allows organizations to inform patients about information usage and their privacy rights. Consent management captures and stores patient authorizations for information disclosures. Access request handling helps organizations respond when patients want copies of their records. These privacy features help organizations fulfill obligations under the HIPAA Privacy Rule. While security prevents unauthorized access, privacy controls manage authorized information usage according to regulatory requirements and patient preferences.

Compliance Evidence Generation

To make a platform HIPAA compliant, entities can adopt solutions that provide documentation capabilities demonstrating regulatory adherence. Configuration documentation shows how security settings protect patient information. Audit reports detail system access and usage patterns for compliance verification. Risk assessment tools help identify potential vulnerabilities within platform implementations. These documentation features support healthcare organizations during internal reviews and external audits. Thorough reporting capabilities allow organizations to demonstrate due diligence in protecting healthcare information when questions arise about compliance status.

Healthcare Process Enablement

Platforms designed for healthcare environments incorporate features that maintain compliance while supporting clinical and administrative workflows. Secure messaging allows providers to discuss patient care without compromising confidentiality. Document management includes appropriate security controls for clinical records. Task management tracks workforce activities while protecting associated patient information. These workflow capabilities allow healthcare organizations to maintain productivity while adhering to regulatory requirements. The platform architecture considers both security needs and practical usage patterns within healthcare environments.

Continuous Protection Adaptation

HIPAA compliant maintenance includes features that support compliance over time as threats evolve. Vulnerability scanning identifies potential security issues as they emerge. Update mechanisms implement security patches without disrupting operations. Configuration management prevents inadvertent changes that might compromise compliance status. Training tools help staff understand proper system usage and security procedures. These management capabilities help organizations maintain compliance as technology and regulations evolve. Effective platforms reduce the administrative burden of ongoing compliance management while maintaining appropriate security controls

HIPAA Email Rules: What You Need to Know

October 16, 2024
LuxSci

The Health Insurance Portability and Accountability Act (HIPAA) is a complicated law that defines the standards for the secure collection, transmission, and storage of protected health information (PHI). When information is stored or exchanged electronically, the HIPAA Security and Privacy Rules require covered entities, i.e., organizations that handle PHI, to safeguard its integrity and confidentiality.

One of the most common ways that PHI is shared electronically is via email, so understanding HIPAA email rules is essential for achieving compliance and protecting sensitive data.

The HIPAA Email Security Rule

It’s important to note that HIPAA does not require the use of any specific technology or vendor to meet its requirements. Generally speaking, the Security Rule requirements for email fall into four categories:

Organizational requirements state the specific functions a covered entity must perform, including implementing policies, procedures and obligations concerning business associate agreements (BAAs).
Administrative requirements relate to employee training, professional development, and management of PHI.
Physical safeguards encompass the security of computer systems, servers, and networks, access to the facility and workstations, data backup and storage, and the destruction of obsolete data and HIPAA email archiving.
Technical safeguards ensure the security of email data transmitted over an open electronic network and the storage of that data.

Let’s move on to discussing some of the main requirements that apply to email and the steps you need to take to secure email accounts that transmit and store PHI.

HIPAA Email Rules: Compliance Checklist

While encryption gets most of the spotlight during discussions on email security, the HIPAA email rules, in contrast, cover a range of behaviors, controls, and services that work together to address eight key areas:

Access
Encryption
Backups and Archival
Defense
Authorization
Reporting
Reviews and Policies
Vendor Management

Let’s look at each aspect of HIPPA’s email rules in greater detail.

1. Access

Access controls help safeguard access to your email accounts and messages. Implementing access controls is essential to keep out unauthorized users and secure your data, with key steps including:

Using strong passwords that cannot be easily guessed or memorized – and changing them frequently, e.g. every 30 days.
Creating different passwords for different sites and applications.
Enabling multi-factor authentication (MFA).
Securing connections to your email service provider using TLS and a VPN.
Blocking unencrypted connections.
Pre-emptively installing software that remotely wipes sensitive email off your mobile device when it is stolen or misplaced.
Logging off from your system when it is not in use and when employees are away from workstations.
Emphasizing opt-out email encryption to minimize breaches resulting from human error.

2. Encryption

Email is inherently insecure and at risk of being read, stolen, intercepted, modified, and forged (repudiated). Covered entities should go beyond the technical safeguards of the HIPAA Security Rule and take steps that exceed what is required to futureproof their communications. Email encryption features to adopt include the following:

The ability to send secure messages to anyone with any email address.
The ability to receive secure messages from anyone.
Implementing measures to prevent the insecure transmission of sensitive data via email.
Exploring message retraction features to retrieve email messages sent to the wrong address.
Avoiding opt-in encryption to satisfy HIPAA Omnibus Rule.

3. Backups and Archival

HIPAA email rules require copies of messages containing PHI to be retained for at least six years. In light of this, organizations must consider the following:

How are email folders backed up?
Are there at least two different backups at two different geographical locations? Additionally, the processes updating these backups should be independent of each other as a measure against backup system failures.
Have you maintained separate, permanent, and searchable archives? While the emails should be tamper-proof, with no way to delete or edit them, they should be easily retrievable to facilitate discovery, comply with audit requests, and support business-critical scenarios.

4. Defense

Cyber threats against healthcare organizations are continually on the increase. Some may be surprised to learn that HIPAA compliant email rules mandate that organizations take steps to defend against possible malicious actors. With this in mind, consider implementing the following technologies:

Server-side inbound email malware and anti-virus scanning to detect phishing messages and malicious links.
Showing the sender’s email address by default on received messages.
Email filtering software to detect fraudulent messages and ensure it uses Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting and Conformance (DMARC) information to classify messages.
Scanning outbound email.
Scanning workstations for malware, i.e., viruses, ransomware, etc.
Using plain text previews of your messages.

5. Authorization

A critical aspect of HIPAA’s email rules is ensuring that cybercriminals cannot impersonate your company or employees. Configuring your domains with SPF and DKIM is essential to verify your identity as an authorized sender of mail from your domains. Also, ensure that users cannot send messages through your email servers without authentication and encryption.

6. Reporting

Setting accountability standards for email security is essential to establishing and strengthening your HIPAA compliance posture. Important steps to take include:

Creating login audit trails.
Receiving login failure and success alerts.
Auto-blocking known attackers.
Maintaining a log of all sent messages.

7. Reviews and Policies

Humans are the greatest vulnerability to any security and compliance plan, so creating policies and procedures that focus on plugging vulnerabilities and preventing human errors is essential. Strategies for reducing risk include:

Inviting independent third parties to review your email policies and user settings. Fresh, unbiased eyes can discover existing issues quickly.
Preventing devices that connect to sensitive email accounts from connecting to public WiFi networks.
Creating email policies prohibiting users from clicking on links or opening attachments that are not expected or requested.

8. Vendor Management

Most companies do not manage their email in-house, so it’s crucial to thoroughly research and vet whoever will be responsible for your email services. Perform an annual review of your email security and stay on top of emerging cybersecurity threats to take proactive action and for continued compliance with HIPAA email rules.

Is the Email Encrypted? How to Tell if an Email is Transmitted Using TLS

January 9, 2024
LuxSci

SMTP TLS encryption is popular because it provides adequate data protection without creating a complicated user experience for email recipients. Sometimes, though, the experience is too seamless, and recipients may wonder if the message was protected at all.

Luckily, there is a way to tell if an email was encrypted using TLS. To see if a message was sent securely, we can look at the raw headers of the email. However, it requires some knowledge and experience to understand the text. It is actually easier to tell if a recipient’s server supports TLS than to tell if a particular message was securely transmitted.

To analyze a message for transmission security, we will look at an example email message sent from Hotmail to LuxSci. We will explain what to look for when decoding the message headers and how to tell if the email was transmitted using TLS encryption.

An Example Email Message

First, we must understand how an email message typically travels through several machines on its way from the sender to the recipient. Roughly speaking:

The sender’s computer talks to the sender’s email or WebMail server to upload the message.
The sender’s email or WebMail server then talks to the recipient’s inbound email server and transmits the message to them.
Finally, the recipient downloads the message from their email server.

It is step 2 that people are most concerned about when trying to understand if their email message is transmitted securely. They usually assume or check that everything is secure and OK at the two ends. Indeed, most users who need to can take steps to ensure that they are using SSL-enabled WebMail or POP/IMAP/SMTP/Exchange services so that steps 1 and 3 are secure. The intermediate step, where the email is transmitted between two different providers, is where messages may be sent insecurely.

To determine if the message was transmitted securely between the sender’s and recipient’s servers (over TLS), we need to extract the “Received” header lines from the received email message. If you look at the source of the email message, the lines at the top start with “Received.” Let’s look at an example message from a Hotmail user below. The email addresses, IPs, and other information are obviously fake.

LuxSci:

The Outlook email was sent to a LuxSci user. The Received headers appear in reverse chronological order, starting with the server that touched the message last. Therefore, in this example, we see the LuxSci servers first.

Received: from abc.luxsci.com ([1.1.1.1])
	by def.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfLgH003867
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 10:41:21 -0400
Received: from abc.luxsci.com (localhost.localdomain [127.0.0.1])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfK0Z030182
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 09:41:20 -0500
Received: (from mail@localhost)
	by abc.luxsci.com (8.14.4/8.13.8/Submit) id r7JEfKXD030178
	for user-xyz@def.luxsci.com; Mon, 19 Aug 2019 09:41:20 -0500

Received: from dispatch1-us1.ppe-hosted.com (dispatch1-us1.ppe-hosted.com [2.2.2.2])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfIkK030002
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <someone@luxsci.net>; Mon, 19 Aug 2019 09:41:19 -0500

Proofpoint:

LuxSci uses an email filtering service, Proofpoint. Messages reach Proofpoint’s servers before being delivered to LuxSci. Here’s what their servers report about the email transmission:

Received: from unknown [65.54.190.216] (EHLO bay0-omc4-s14.bay0.hotmail.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (envelope-from <someone@hotmail.com>);
	Mon, 19 Aug 2019 08:41:18 -0600 (MDT)

Outlook:

And finally, here’s what we see from Oultook’s server.

Received: from BAY403-EAS373 ([65.54.190.199]) by bay0-omc4-s14.bay0.outlook.com
       with Microsoft SMTPSVC(6.0.3790.4675); 
       Mon, 19 Aug 2019 07:41:19 -0700

How to Use Received Message Headers to Tell if the Email is Encrypted

The message headers contain information that can help us determine if an email is encrypted. Here are a few helpful notes to help you decode the text:

We said this above, but the message headers appear in reverse chronological order. The first one listed shows the last server that touched the message; the last one is the first server that touched it (typically the sending server).
Each Received line documents what a server did and when.
There are three sets of servers involved in this example: one machine at Hotmail, one machine at Proofpoint, where our Premium Email Filtering takes place, and some machines at LuxSci, where final acceptance of the message and subsequent delivery happened.

Presumably, the processing of email within each provider is secure. The place to be concerned about is the hand-offs between Hotmail and Proofpoint and between Proofpoint and LuxSci, as these are the big hops across the internet between providers.

In the line where LuxSci accepts the message from Proofpoint, we see:

(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)

This section, typical of most email servers running “sendmail” with TLS support, indicates that the message was encrypted during transport with TLS using 256-bit AES encryption. (“Verify=not” means that LuxSci did not ask Proofpoint for a second SSL client certificate to verify itself, as that is not usually needed or required for SMTP TLS to work correctly). Also, “TLSv1/SSLv3” is a tag that means that “Some version of SSL or TLS was used;” it does not mean that it was SSL v3 or TLS v1.0. It could have been TLS v1.2 or TLS v1.3.

So, the hop between Proofpoint and LuxSci was locked down and secure. What about the hop between Hotmail and Proofpoint? The Proofpoint server’s Received line makes no note of security at all! This means that the email message was probably not encrypted during this step.

Hotmail either did not support opportunistic TLS encryption for outbound emails, or Proofpoint did not support receipt of messages over TLS, and thus, TLS could not be used. With additional context, you can know which server supports TLS and which does not.

In this case, we know that Proofpoint supports inbound TLS encryption. In fact, from another example message where LuxSci sent a message to Proofpoint, we see the Received line:

Received: from unknown [44.44.44.44] (EHLO wgh.luxsci.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits))
	with ESMTP id b-022.p01c11m003.ppe-hosted.com
        (envelope-from <from@domain.com>);
	Mon, 02 Feb 2009 19:28:27 -0700 (MST)

The red text makes it clear that the message was indeed encrypted. Based on the additional context, we can deduce that the Hotmail sending server did not securely transmit the email using TLS.

How To Tell if an Email is Encrypted With TLS

When analyzing your message headers, consider the following items to determine if the email is encrypted:
1. The receiving server will log what kind of encryption, if any, was used in receiving the message in the headers.
2. Different email servers use different formats and syntax to display the encryption used. Look for keywords like “SSL,” “TLS,” and “Encryption,” which will signify this information.
3. Not all servers will record the use of encryption. While LuxSci has always logged encryption use, not every email service provider does. It is possible to use TLS encryption and not log it. Sometimes, there is no way to tell from the headers if a message is encrypted if it is not logged.
4. Messages passed between servers at the same provider do not necessarily need TLS encryption to be secure. For example, LuxSci has back-channel private network connections between many servers so that information can be securely passed between them without SMTP TLS. So, the lack of TLS usage between two servers does not mean the transmission between them was “insecure.” You may also see multiple received lines listing the same server: the server passes the message between different processes within itself. This communication also does not need to be TLS encrypted.
5. If you are a LuxSci customer, you can view online email delivery reports to see if TLS was used for any particular message. We record the kind of encryption in the delivery reports, so it’s easy to see which emails were encrypted.

How can you Ensure Emails Are Securely Transmitted?

With some servers not recording TLS in message headers, how can you determine if a message was transmitted securely from sender to recipient?

To answer this question accurately, you must understand the properties, servers, and networks involved. It may be easy to determine that the message was transmitted securely if included in the header information. However, the absence of information does not necessarily mean the message was insecurely transmitted. You can only know this if you know what each system’s servers record.

In our example of a message from Hotmail to LuxSci, you need to know that:

Proofpoint and LuxSci will always log the use of TLS in the headers. We can infer that the Hotmail to Proofpoint transmission was not secure as nothing was recorded there.
The transmission of messages within LuxSci’s infrastructure is secure due to private back channel transmissions. So, even though there is no mention of TLS in every Received line after LuxSci accepts the message from Proofpoint (in this example), transferring the messages between servers in LuxSci is as secure as using TLS. Also, the same server can add multiple received lines as it talks to itself. Generally, these hand-offs on the same server will not use TLS, as there is no need. In the LuxSci example, we see this as “abc.luxsci.com” adds several headers.
We don’t know anything about Hotmail’s email servers, so we don’t know how secure the initial transmissions within their network are. However, since we know they did not securely transmit the message to Proofpoint, we are not confident that the transmissions and processing within Hotmail (which may have gone unrecorded) were secure.

Was the email message sent and received using encryption?

We skipped steps 1 and 3 and focused on step 2 – the transmission between servers. Steps 1 and 3 are equally, if not more, necessary. Why? Because eavesdropping on the internet between ISPs is less of a problem than eavesdropping near the sender and recipient (i.e., in their workplace or local wireless hotspot). So, it’s essential to ensure messages are sent securely and received securely. This means:

Sending: Use SMTP over SSL or TLS when sending messages from an email client or use WebMail over a secure connection (HTTPS).
Receiving: Ensure your POP or IMAP connection is secured via SSL or TLS. If using WebMail to read your email, be sure it is over a secure connection (HTTPS).
WebMail: There is generally no record in the email headers to indicate if a message sent using WebMail was transmitted from the end-user to WebMail over a secure connection (SSL/HTTPS).

You can typically control one side and ensure it is secure; you can’t control the other without taking extra steps. So, what can you do to ensure your message is secure even if it might not be transmitted with encryption or if the recipient tries to access it insecurely?

You could use end-to-end email encryption (like PGP or S/MIME, which are included in SecureLine) or a secure web portal that doesn’t require the recipient to install or set up anything to get your secure email message. These methods meet HIPAA and other regulatory compliance requirements for secure data transmission and provide complete confidence that the message will be sent and received securely.

LuxSci’s SecureLine offers flexible encryption options, including TLS, secure web portal, PGP, and S/MIME. Its dynamic capabilities can determine what types of encryption the recipient’s server supports to ensure your emails are always sent securely.
