Why Email Needs to Be HIPAA-Compliant

HIPAA Privacy Rule & Email

The HIPAA Privacy Rule defines protected health information (PHI) and limits how it’s used or disclosed.
According to HHS guidance, providers may email patients about health issues — but only with proper safeguards.

HIPAA Security Rule: Technical Safeguards

The HIPAA Security Rule requires administrative, physical, and technical controls to protect electronic PHI (ePHI). Email systems must include access controls, audit logs, and encryption to prevent data breaches.
As HIPAA Journal notes, sending PHI through regular, unencrypted email can constitute a HIPAA violation.

Key Features of a HIPAA Compliant Email Service

Encryption in Transit and at Rest

Encryption is the backbone of secure communication. HIPAA Journal emphasizes that while encryption is “addressable,” it’s the most practical safeguard.

  • Use TLS or higher for transit encryption (HIPAA Vault guide).
  • Use AES-256 or stronger encryption at rest.

Access Control, Audit Logging, and Integrity

A HIPAA compliant email service must enforce role-based access, MFA, and track message activity. These logs help prove compliance during audits.

Business Associate Agreement (BAA)

Always execute a Business Associate Agreement with your provider. Without a signed BAA, even encrypted email may not meet compliance.

Archiving and Retention

Archiving protects PHI integrity and supports audit trails. Your email service should allow retention rules aligned with HIPAA requirements.

Integration with Existing Systems: Outlook, Gmail & Beyond

Using Google Workspace or Microsoft 365

Google Workspace and Microsoft 365 can be HIPAA compliant — but only if configured correctly and paired with a BAA. Encryption must be enforced, and risky features like auto-forwarding must be disabled.

Plug-ins and Add-Ons for Legacy Systems

If your practice uses standard Gmail or Outlook, third-party HIPAA email gateways (like Paubox or Virtru) can integrate encryption without changing your workflow. See the full HIPAA Vault overview for integration examples.

How to Choose the Right HIPAA Compliant Email Provider

Map Your Use Case

Identify how your team exchanges PHI: patient communication, referrals, billing, or internal notes. Match those needs to provider features.

Consider Cost, Support & Training

A low-cost provider without onboarding or training may increase errors. Choose one with accessible support and HIPAA expertise.

Evaluate Migration, Archiving, and Retention

Ensure your provider supports smooth migration and HIPAA-aligned archiving. See HIPAA Vault’s Security Rule Checklist to verify technical controls.

Verify Vendor Trustworthiness

Ask about security audits, SOC 2 reports, and prior breach disclosures. A reliable vendor is transparent about compliance documentation.

Common Pitfalls & Compliance Risks

  • Sending PHI through unencrypted channels
  • Using Gmail/Outlook without a signed BAA
  • Failing to configure encryption and audit settings
  • Ignoring state laws on patient consent
