The Best HIPAA-Compliant Email Providers

HIPAA-Compliant Email Providers

Healthcare providers must comply with the Health Insurance Portability and Accountability Act (HIPAA). It is a U.S. federal law that establishes a set of guidelines and regulations to protect the safety, integrity, and availability of the Protected Health Information (PHI) of your patients.

As PHI is sensitive and can infringe on the patient’s privacy and security, you must take all measures to secure your communication with patients. Moreover, patients must have the right to access their data and decide how they want it to be communicated. Violations of any of these aspects can lead to non-compliance which will eventually result in hefty fines.

To avoid these fines and the responsibilities that come with securing PHI in emails, many healthcare providers prefer using HIPAA-compliant services.

The best HIPAA-Compliant Email Providers are as follows:

  1. Egress An intelligent email security service that comes with mechanisms like anti-phishing, data loss, revocation, smart authentication, and more. It is designed to keep all emails safe and HIPAA compliant.
  2. LuxSci An email service that offers end-to-end encryption to protect sensitive data from unintentional exposure. It also enables you to securely communicate with patients while protecting your sensitive data.
  3. Hushmail A proprietary web-based email for HIPAA compliance. It also supports web forms and e-signatures and supports the transmission of authenticated and encrypted emails in both directions.

  6. ProtonMail An email provider known for its security and privacy, ProtonMail provides complete control with end-to-end encryption. Its add-ons like Calendar, Drive, and VPN also come in handy.
  7. MailHippo A secure email service for sending and receiving emails and attachments. It is 100% HIPAA-compliant.

Why Use HIPAA-compliant Email Providers?

According to HIPAA, covered entities are healthcare providers including doctors, nurses, dentists, and other practitioners, health insurance plans, and healthcare clearinghouses. Other entities that agree with these covered entities through a Business Associate Agreement (BAA) are called business associates.

These business associates are those who store, process, and handle PHI or any other data that can identify a specific patient. These associates also have to comply with HIPAA requirements. Email service providers are business associates and they enter into a BAA with insurance providers.

When it comes to emails, HIPAA does not lay any explicit rules except that the emails must conform to its Security and Privacy laws. Unfortunately, most Internet-based emails like Gmail are not secure and do not fully cover these Privacy and Security laws. This is where specialized email services are necessary.

As a healthcare provider, when you choose a HIPAA-compliant email service, it is deemed that you’ve taken all necessary precautions to protect the transmission of ePHI. In case of a data breach, the business associates face fines.

Due to this advantage, many healthcare providers prefer to choose a secure and HIPAA-compliant email provider. However, not all providers are the same. You must look for aspects like

  • A clear definition of each party’s responsibility.
  • The permitted PHI used by business associates.
  • The measures taken by the provider to ensure that PHI is not used or disclosed beyond the terms of the BAA.
  • Availability of appropriate safeguards like encryption, logging, authentication, audit trails, archiving, and more.

Our Methodology

Our methodology for evaluating email providers:

  • The security aspects like advanced encryption (preferably AES or OpenPGP algorithms),
  • Location of servers that store or transmit the emails.
  • It does not log or track data.
  • Availability of email expiration options.
  • Level of HIPAA compliance.
  • Usability and validation checks that are in tune with the HIPAA rules.
