Email communications are essential within the healthcare industry, allowing fast, secure and cost-effective communication between healthcare professionals and their patients. But with the security of patient data at the forefront of everyone’s minds, how do HIPAA guidelines affect the use of email within this sector?

What Is HIPAA-Compliant Email?

HIPAA-compliant email should be used whenever Protected Health Information (PHI) is being sent or discussed. For an email service to be HIPAA-compliant, it should offer the necessary security measures including end-to-end encryption, access controls, multi-factor authentication, integrity controls, and a signed Business Associate Agreement (BAA).

Standard email providers do not offer their users a HIPAA-compliant service as standard, therefore healthcare organizations must research their options carefully to find a provider that complies fully with the HIPAA guidelines. To make this easier, we have compiled a list of top HIPAA-compliant email providers based on their best practices and the standard of service that they offer healthcare organizations.
