Growing numbers of healthcare organizations are turning to Customer Data Platforms (CDPs) to consolidate and leverage patient data (or electronic protected health information (ePHI) from electronic health record (EHR) systems, RCM platforms, CRM systems, websites, communications channels, and other various sources. 

CDPs enable healthcare providers, payers, and retailers to better understand each patient’s needs, health conditions, treatment schedules, ongoing care, and so on, enabling them to take the right actions, at the right time to improve engagement. This results in more patient participation, enhanced coordination with providers and companies, and, ultimately, improved patient outcomes.

Why Should You Integrate CDPs and Email?

Integrating the functionality of a CDP with a HIPAA compliant email platform, such as LuxSci, empowers you to put your data into action. This includes enabling you to better target your various segments using real-time communications data – such as email opens, clicks and conversions – as well as using PHI in secure messages for greater personalization – all while operating within the bounds of HIPAA (the Health Insurance Portability and Accountability Act) regulations. 

With this in mind, this post discusses the benefits of integrating your organization’s CDP solution with a HIPAA compliant email solution. We’ll explore the main benefits and how to integrate the two solutions, as well as several effective strategies for leveraging the valuable PHI stored within your CPD to increase patient and customer engagement.

Benefits of Integrating a CDP with HIPAA Compliant Email

Let’s begin by looking at the main advantages of pairing your CDP with a HIPAA compliant email platform.

Increased Protection of Customer Data

Above all, HIPAA compliant email platforms are specifically designed with the stringent data privacy and security requirements of the healthcare industry in mind. As a result, they contain a range of data security features, including encryption, access control, user authentication, and audit logging, that both better safeguard ePHI from unauthorized access and ensure HIPAA compliance. In short, HIPAA compliant email helps ensure that when valuable and sensitive CDP information is put into use, i.e. using it in patient emails and communications, it’s protected and safe both in transit and at rest.

Avoid the Consequences of HIPAA Violations

By opting for an email provider that meets the security requirements for HIPAA compliance – and better yet, HITRUST certification – your company can better mitigate the risk of data breaches, and the compliance violations that accompany them. The consequences of HIPAA compliance violations include: 

• Financial penalties: this includes regulatory fines, legal fees and compensation to affected parties, and state-level fines (in certain cases). In the event that compliance officers can prove willful neglect, your company may even face criminal charges, incurring further damage.  
• Operational disruptions: suffering a security breach requires healthcare organizations to spend time on containment and notifying and reassuring affected parties, as well as taking subsequent mitigation efforts – all of which take time away from running the day-to-day business.
• Reputational damage: displaying an inability to safeguard sensitive data will cause patients and customers to lose trust in your organization and move to other providers or suppliers.

Enhanced Personalization in Engagement Efforts

With ongoing uncertainty around HIPAA regulations, healthcare companies are often reluctant to include PHI in their email communications and campaigns, missing opportunities to fully leverage your CDP to create more effective, more relevant messages, targeting highly segmented audiences. Safe in the knowledge that customer data derived from your CDP will be secured by your HIPAA compliant email provider or HIPAA compliant marketing solution, you can confidently include PHI in communications to craft more personalized – and potent – engagement opportunities.  

The data aggregated by CDPs can be used to divide, or segment, customers into smaller groups with particular commonalities, such as a health condition like diabetes, or users of a particular type of medical equipment. Healthcare marketers can use the shared needs and problems of each patient or customer segment to drive more effective and targeted campaigns that deliver more opens, clicks, and conversions.

Strategies for Leveraging Customer Data Through CDP and Email Integration

Having a better understanding of the benefits of CDP integration with your email communications, let’s move on to a few of the most effective ways to leverage your customer data through a HIPAA compliant, secure email services provider (ESP).

Segmenting Customers by Health Condition or Risk Profile

The first strategy, as alluded to above, is to use the health-oriented data stored in your CDP to group customers into segments that you can target with highly personalized messaging – using PHI to your advantage. Segmentation could be based on health conditions, such as demographics, location, or by a patient’s lifestyle risk factors, e.g., smokers. 

Having defined your segments, you can create personalized email campaigns for each, which are far more likely to drive engagement and actions versus messages designed to appeal to everyone or with limited information. Better still, you can create different email campaigns to fulfill different purposes with automated workflows based on how your patients respond, giving you a range of opportunities to reach out and connect. Using intelligence from your CDP, you can design your email campaigns to:

• Educate: send patients and customers educational materials designed to increase their understanding of their state of health and the options available to them for creating the most favorable outcomes. 
• Offer adherence advice: include information on how to best adhere to a prescribed care or treatment plan, resources on overcoming common challenges, where to go for support, etc. 
• Provide preventive care tips: help patients who fit a particular risk profile, such as diabetes or heart disease, make better lifestyle choices, with the ultimate aim of avoiding the disease they’re at risk of. 

Lifecycle-Based Messaging

This is a variation on the above strategy that segments patients and customers based on how far along they are in their treatment lifecycle, for instance: 

• Onboarding: messaging that introduces your services, explains how to access care, and covers other preliminary details; this stage is essential for setting expectations and establishing trust with your patients and customers.
• Active Treatments: regular check-ins, medication reminders, preparation guides, and educational resources based on their condition or treatment plan; this messaging is designed to support adherence and improve healthcare outcomes.
• Follow-Up and Recovery: personalized care instructions, satisfaction surveys, or information about next steps; this shows ongoing support and maintains consistent communication when a patient may be feeling most vulnerable. 
• Preventive and Long-Term Care: triggering routine screening reminders, vaccine alerts, or wellness tips based on age, history, and risk factors; an integrated CDP and email system can track when patients are due for services and automate communication accordingly.
• Re-engagement: sending patients who have been inactive for a while tailored prompts, e.g., “We haven’t seen you in a while…”; this encourages proactivity and helps highlight new services that may be of interest.

Behavior-Triggered Messaging

Integrating your CDP with a HIPAA compliant email platform enables you to automate email delivery and workflows based on a customer’s behavior and engagement patterns. This type of email is enabled by the CDP’s ability to monitor events and behaviors across multiple activities and locations, enabling you to create email campaign strategies and workflows accordingly. This approach allows for a range of timely and relevant engagement opportunities, including: 

• Missed appointments: sending a message if a patient misses an appointment that encourages them to reschedule and assists them in how to do so. 
• Periodic checkup reminders: similarly, if a patient is supposed to have regular checkups, follow-up appointments, a recommended health screening, etc., this data can be passed from the CDP to the email client to schedule automated emails that drive up appointment bookings.  
• Unfilled prescriptions: if a patient hasn’t picked up their prescribed medication, you can automatically trigger an email reminder and automated workflow to get the prescription filled; this information can also be fed back to their healthcare providers if repeated reminders see the prescription remain unfilled. 
• Patient portal inactivity: if a user hasn’t logged into a portal for a predefined time frame, this can prompt a re-engagement email encouraging them to check messages in their portal, view test results, etc. 
• Form completion: after inputting data into a web form, an integrated CDP can help facilitate the delivery of a tailored email that offers guidance on next steps or the most relevant products or services based on given answers.

Implement Feedback Loops for Optimized Engagement

Finally, a key benefit of integrating a CDP with a HIPAA compliant email platform is that it enables you to close the loop between engagement and results. By feeding campaign performance data, such as email opens, clicks, conversions, and other key metrics, back into your CDP, you can continuously refine your email outreach strategies to enhance engagement, while developing a more complete data profile of patients and customers.

Due to its near-universal adoption, speed, and cost-effectiveness, email remains one of the most common communication channels in healthcare. Consequently, it’s one of the most frequent targets for cyber attacks, as malicious actors are acutely aware of the vast amounts of sensitive data contained in messages – and standard email communication’s inherent vulnerabilities.

In light of this, healthcare organizations must remain aware of the evolving email threat landscape, and implement effective strategies to protect the electronic protected health information (ePHI) included in email messages. Failing to properly secure email communications jeopardizes patient data privacy, which can disrupt operations, result in costly HIPAA compliance violations, and, most importantly, compromise the quality of their patients’ healthcare provision.

With all this in mind, this post details the biggest email threats faced by healthcare organizations today, with the greatest potential to cause your business or practice harm by compromising patient and company data. You can also get our 2025 report on the latest email threats, which includes strategies on how to overcome them.

Ransomware Attacks

Ransomware is a type of malware that encrypts, corrupts, or deletes a healthcare organization’s data or critical systems, and enables the cybercriminals that deployed it to demand a payment (i.e., a ransom) for their restoration. Healthcare personnel can unwittingly download ransomware onto their devices by opening a malicious email attachment or clicking on a link contained in an email.

In recent years, ransomware has emerged as the email security threat with the most significant financial impact. In 2024, for instance, there were over 180 confirmed ransomware attacks with an average paid ransom of nearly $1 million. 

Email Client Misconfiguration

While a healthcare organization may implement email security controls, many fail to know the security gaps of their current email service provider (ESP) or understand the value of a HIPAA compliant email platform, leaving data vulnerable to email threats, such as unauthorized access and ePHI exposure, and also, subsequently, a greater risk of compliance violations and reputation damage.

Common types of email misconfiguration include:

• Lack of enforced TLS encryption: resulting in emails being transmitted in plaintext, rendering the patient data they contain readable by cybercriminals in the event of interception during transit.
• Improper SPF/DKIM/DMARC setup: failure to configure or align these email authentication protocols correctly gives malicious actors greater latitude to successfully spoof trusted domains.
• Disabled or lax user authentication: a lack of authentication measures, such as multi-factor authentication (MFA), increases the risk of unauthorized access and ePHI exposure.
• Misconfigured secure email gateways: incorrect rules or filtering policies can allow phishing emails through or block legitimate messages.
• Outdated or unsupported email client software: simply neglecting to download and apply the latest updates or patches from the email client’s vendor can leave vulnerabilities, which are well-known to cybercriminals, exposed to attack.

Social Engineering Attacks

A social engineering attack involves a malicious actor deceiving or convincing healthcare employees into granting unauthorized access or exposing patient data. Relying on psychological manipulation, social engineering attacks exploit a person’s trust, urgency, fear, or curiosity, and encompass an assortment of threats, including phishing and business email compromise (BEC) attacks, which are covered in greater depth below.

Phishing

As mentioned above, phishing is a type of social engineering attack, but they are so widespread that it warrants its own mention. Phishing sees malicious actors impersonating legitimate companies, or their employees, to trick victims into revealing sensitive patient data. 

Subsequently, healthcare organizations can be subjected to several different types of phishing attacks, which include:

• General phishing: otherwise known as bulk phishing or simply ‘phishing’, these are broad, generic attacks where emails are sent to large numbers of recipients, impersonating trusted entities to steal credentials or deliver malware. 
• Spear phishing: more targeted attacks that involve personalized phishing emails crafted for a specific healthcare organization or individual. These require more research on the part of malicious actors and typically use relevant insider details gleaned from their reconnaissance for additional credibility.
• Whaling: a form of spear phishing that specifically targets healthcare executives or other high-level employees. 
• Clone phishing:  when a cybercriminal duplicates a legitimate email that was previously received by the target, replacing links or attachments with malicious ones.
• Credential phishing: also known as ‘pharming’, this involves emails that link to fake login pages designed to capture healthcare employees’ usernames and passwords under the guise of frequently used legitimate services.

Domain Impersonation and Spoofing

This category of threat revolves around making malicious messages appear legitimate, which can allow them to bypass basic email security checks. As alluded to above, these attacks exploit weaknesses in email client misconfigurations to trick the recipient, typically to expose and exfiltrate patient data, steal employee credentials, or distribute malware.

Domain spoofing email threats involve altering the “From” address in an email header to make it appear to be from a legitimate domain. If a healthcare organization fails to properly configure authentication protocols like SPF, DKIM, and DMARC, there’s a greater risk of their email servers failing to flag malicious messages and allowing them to land in users’ inboxes.

Domain impersonation, on the other hand, requires cybercriminals to register a domain that closely resembles a legitimate one. This may involve typosquatting, e.g., using “paypa1.com” instead of “paypal.com”. Alternatively, a hacker may utilize a homograph attack, which substitutes visually similar characters, e.g., from different character sets, such as Cyrillic. Malicious actors will then send emails from these fraudulent domains, which often have the ability to bypass basic email filters because they aren’t exact matches for blacklisted domains. Worse still, such emails can appear authentic to users, particularly if the attacker puts in the effort to accurately mimic the branding, formatting, and tone used by the legitimate entity they’re attempting to impersonate. 

Insider Email Threats

In addition to external parties, employees within a healthcare organization can pose email threats to the security of its PHI. On one hand, insider threats can be intentional, involving disgruntled employees or third-party personnel abusing their access privileges to steal or corrupt patient data. Alternatively, they could be the result of mere human error or negligence, stemming from ignorance, or even fatigue.

What’s more, insider threats have been exacerbated by the rise of remote and flexible conditions since the onset of the COVID-19 pandemic, which has created more complex IT infrastructures that are more difficult to manage and control.  

Business Email Compromise (BEC) Attacks

A BEC attack is a highly targeted type of social engineering attack in which cybercriminals gain access to, or copy, a legitimate email account to impersonate a known and trusted individual within an organization. BEC attacks typically require extensive research on the targeted healthcare company and rely less on malicious links or attachments, unlike phishing, which can make them difficult to detect.

Due to the high volume of emails transmitted within the healthcare industry, and the sensitive nature of PHI often included in communications to patients and between organizations, the healthcare industry is a consistent target of BEC attacks.

BEC attacks come in several forms, such as:

• Account compromise: hijacking a real employee’s account and sending fraudulent messages.
• Executive fraud: impersonating high-ranking personnel to request urgent financial transactions or access to sensitive data.
• Invoice fraud: pretending to be a vendor asking for the payment of a fraudulent invoice into an account under their control.

Supply Chain Risk

Healthcare organizations increasingly rely on third-party vendors, including cloud service providers, software vendors, and billing or payment providers to serve their patients and customers. They constantly communicate with their supply chain partners via email, with some messages containing sensitive patient data; moreover, some of these organizations will have various levels of access to the PHI under their care.

Consequently, undetected vulnerabilities or lax security practices within your supply chain network could serve as entry points for email threats and malicious action. For instance, cybercriminals can compromise the email servers of a healthcare company’s third-party vendor or partner, and then send fraudulent emails from their domains to deploy malware or extract patient data.

Another, somewhat harrowing, way to understand supply chain risk is that while your organization may have a robust email security posture, in reality, it’s only as strong as that of your weakest third-party vendor’s security controls.
