Healthcare providers, payers, and suppliers increasingly rely on email communication for a wide variety of purposes pertaining to their patients’ and customer’s healthcare journeys. However, ensuring email messaging is both effective and HIPAA compliant requires the right infrastructure, including dedicated environments, high throughput and low latency, end-to-end encryption, scalability and compliance monitoring.

The Health Insurance Portability and Accountability Act’s (HIPAA) regulations mandate a series of data security and privacy requirements to safeguard the electronic protected health information (ePHI) contained in emails, which is a good place to start. At the same time, however, healthcare organizations must also consider deliverability best practices to ensure their messages successfully reach the intended recipients. 

With all this in mind, this post discusses the infrastructure requirements for HIPAA compliant email. We’ll explore the differences between transactional and marketing emails, as well as infrastructure and compliance considerations for each. 

What Are Transactional Emails?

Transactional emails are messages that correspond to a previous interaction between a healthcare organization and an individual. A patient or customer will trigger the delivery of a transactional email by taking a specific action – with the transaction email being confirmation of the action.  

Examples of transactional emails include:

• Explanation of Benefits
• Billing statements
• Invoices
• Appointment confirmations and reminders
• Order updates and shipping notifications
• Password resets and security notifications
• Plan renewal confirmation 
• Payment failure notifications
• In-home care communications

Healthcare companies can also use transactional emails to communicate relevant instructions, next steps, or follow-up actions.

What Are Marketing Emails?

Marketing emails contain content designed to influence the recipient into taking a particular action, usch as ordering a new product or sign up for a new service. Subsequently, they often contain informational materials intended to educate the individual so they can make a more informed decision. 

Examples of marketing emails include:

• New product or service launches
• Promotional offers
• Loyalty reward notifications 
• Customer reviews and testimonials 
• Educational materials or campaigns 
• Preventative care outreach
• Event Invitations
• Re-engagement messages (e.g., “We Miss You!..”)

With the proper data safeguards and the effective use of ePHI, marketing emails can be personalized to be made more relevant to the recipient. This then allows patients or customers to be segmented into subgroups according to particular commonalities, e.g., age, gender, lifestyle factors, medical conditions, etc.

Opt-in Rules for HIPAA-Compliant Email Communication 

One significant difference between marketing and transactional emails is that recipients must explicitly opt-in to receive marketing emails. 

HIPAA requires explicit patient consent for marketing emails if they contain ePHI, requiring individuals to opt-in to receive email marketing communications from a healthcare organization. Neglecting to allow people to opt-in to your marketing communications leaves your company open to the consequences of HIPAA non-compliance, which include financial penalties and reputational damage. 

Conversely, healthcare organizations aren’t required to obtain opt-ins to send transactional emails, but these communications are still subject to other HIPAA regulations, such as encryption and audit logging. 

Additionally, marketing emails must comply with the CAN-SPAM Act: US legislation that governs commercial email communication and protects individuals from deceptive sales and marketing practices. The CAN-SPAM Act requires healthcare organizations to provide an opt-out mechanism in the event they no longer wish to receive marketing emails. Subsequently, you must always allow individuals to opt out of marketing emails to stay compliant.

Email Infrastructure Requirements For HIPPA-Compliance

As the vast majority of healthcare organizations need to send marketing and transactional emails, they must have the appropriate infrastructure to facilitate the optimal delivery of both types of emails. Consequently, for HIPAA compliant email, they need to establish the appropriate infrastructure configurations for each, according to their differing purposes, sending patterns, and compliance considerations. 

Let’s look at the infrastructure requirements for each email type in turn, before looking at considerations that pertain to both types of email.

Key Transactional Email Infrastructure Considerations

Transactional emails are sent to a sole patient or customer, with the information therein only intended for that specific individual. Additionally, they can be highly time-sensitive: for example, a password reset or similar emails related to logins and service use must be immediate, while order confirmations need to be delivered ASAP to reassure clients of a company’s reliability and trustworthiness. 

Accounting for this, the infrastructure requirements for transactional emails include: 

• High Speed and Low Latency: servers that are optimized  for high IOPS (input/output operations per second) and minimal processing delays to ensure near-instant delivery
• Dedicated IPs: this helps healthcare companies maintain a strong sender reputation to avoid blacklisting, being labelled as spam, etc. This is crucial for reliable, fast delivery. 
• High Availability and Redundancy: this includes load balancers, failover servers, and geographically distributed data centers to ensure comprehensive disaster recovery and more robust business continuity protocols.  

Key Marketing Email Infrastructure Considerations

In contrast to transactional messages, marketing emails must often be sent out in high volumes, which could be as many as hundreds of thousands or millions per month. As a result, marketing email campaigns have different computational demands, i.e., CPU and storage, than transactional messages intended for a single person. 

Subsequently, the infrastructure requirements for marketing emails include: 

• High Volume and Scalability: marketing messages require a larger throughput to facilitate the bulk delivery of email. Additionally, servers should scale easily to accommodate increasingly larger campaigns without suffering bottlenecks.
• Queueing and Throttling: marketing email infrastructure must prevent sending surges that could trigger spam filters or overload recipient servers, which often results in blacklisting. 
• Dedicated vs. Shared Infrastructure: it’s important to consider whether to opt for private versus shared infrastructure, depending on the size of your organization and the scale of your campaigns. Large senders often use dedicated IPs for better control, while smaller companies or campaigns might use shared pools with strict sender reputation management.

Key Infrastructure Considerations for Both Types of Email

Lastly, there are infrastructure requirements that apply to both types of email that will help facilitate their fast and reliable delivery, respectively. These include:     

• Separate Infrastructure: consider hosting your transactional and marketing emails on separate servers. This benefits transactional emails in particular, as there are several factors inherent to marketing email campaigns, such as bounced emails and being flagged as spam, that affect an email IP’s reputation. Separate infrastructure maintains the integrity of a healthcare company’s IP address for transactional emails, ensuring they are delivered unimpeded. 
• Encryption: the ePHI in all email communications must be encrypted in transit, i.e., when sent to individuals, and at rest, i.e., when stored in a database. This helps safeguard the patient data within the message, regardless of its nature. 
• HIPAA Compliance Monitoring: remaining aware of what ePHI is included in email communications. This keeps data exposure to a minimum and mitigates the unintentional inclusion of patient data in email communications. 
• Logging and Auditing: this not only allows you to track email activity, but you also can measure the efficacy of your email communications, who accessed ePHI, and what they did with it. This is an essential part of HIPAA compliance and will be subject to tighter regulation when the updates to HIPAA’s Security Rule come into effect in late 2025.

PHI email becomes compliant through end-to-end encryption, access controls, audit trails, and secure transmission protocols. Healthcare organizations must implement email solutions that encrypt protected health information both in transit and at rest, maintain detailed logs of all communications, and restrict access to authorized personnel only. Medical practices encounter the challenges of patient information travelling through digital communication channels, as each message contains names, medical record numbers, or treatment details. Patient communications flow through healthcare systems constantly, creating numerous opportunities for data exposure. Email messages containing appointment confirmations, lab results, or billing inquiries must receive the same protection level as paper records stored in locked cabinets. The difficulty increases when metadata reveals patient-provider relationships without obvious identifying information appearing in message content itself.

Email Encryption Methods Protect Patient Data

Healthcare email platforms deploy Advanced Encryption Standard protocols with 256-bit keys to render intercepted messages unreadable without proper decryption credentials. Transport Layer Security protocols shield communications during transmission between mail servers, while storage encryption protects messages residing in email systems. These protection layers work to secure PHI email whether traveling across networks or sitting in user mailboxes.

Identity-based encryption provides an alternative where recipients authenticate through secure web portals instead of managing encrypted attachments with complex passwords. Patients log into portal systems once and access their messages without downloading files or remembering multiple authentication credentials for different healthcare providers.

User Access Controls Prevent Information Breaches

Multi-factor authentication requires users to provide passwords, mobile verification codes, and sometimes biometric data before accessing PHI email systems. Staff members receive permissions aligned with their job responsibilities, preventing billing personnel from reading clinical notes while restricting nurses from accessing financial communications. These permission structures eliminate accidental information exposure between healthcare departments.

Session timeouts automatically disconnect users after inactivity periods, and systems monitor failed login attempts to detect potential unauthorized access. Organizations document access permissions and conduct monthly reviews to ensure appropriate information boundaries. Employee departures trigger immediate email access revocation to prevent data exposure after employment ends.

Monitoring Systems Track Message Activities

Modern PHI email platforms record message creation, transmission, delivery, viewing, forwarding, and deletion activities. These logs include timestamps, user identifications, and recipient information that create detailed records for compliance reviews and incident investigations. Healthcare organizations must preserve these records for six years and provide them during HIPAA audits.

Behavioral analysis systems detect unusual patterns like mass message downloads during off-hours or attempts to redirect communications to personal email accounts. Security teams receive immediate notifications when suspicious activities occur, enabling rapid investigation of potential breaches or unauthorized access attempts.

Vendor Contracts Define Compliance Obligations

Email service providers handling patient information must execute business associate agreements outlining their compliance responsibilities. These contracts address data protection standards, breach notification timelines, and audit cooperation requirements. Cloud email providers must prove their systems meet HIPAA standards through independent security assessments.

Healthcare organizations bear liability for vendor compliance failures, making thorough evaluation processes necessary before selecting email platforms. Assessment procedures examine data storage locations, infrastructure security measures, and incident response capabilities to ensure adequate protection throughout the technology supply chain.

Employee Education Prevents Security Violations

Training programs teach staff to identify phishing attempts, follow acceptable use policies, and handle PHI email appropriately. Organizations conduct simulated phishing exercises to evaluate employee responses to suspicious messages and provide additional education for those requiring improvement. Policies clarify when staff should use secure messaging platforms instead of traditional email systems.

Content filtering systems scan outgoing messages for Social Security numbers, medical record numbers, and other patient identifiers. When these systems detect sensitive information, they automatically apply encryption or prevent message transmission until users implement appropriate security measures.

Performance Tracking Ensures Program Effectiveness

Healthcare organizations monitor encryption usage rates, policy compliance scores, and incident response times to evaluate their PHI email programs. Monthly assessments examine compliance trends and identify areas where system improvements or additional training could strengthen protection. Risk evaluations examine emerging threats and technology changes that might affect email security.

Compliance teams review email policies quarterly and update procedures based on regulatory developments or security incidents. System testing verifies that encryption, access controls, and monitoring functions operate correctly under various usage conditions, ensuring patient communications receive consistent protection through all organizational email activities.
