What is DMARC?

Domain-based Message Authentication, Reporting & Conformance, or DMARC, is an email authentication tool that prevents data spoofing, tampering, phishing, and cyberattacks.

How does DMARC work?

DMARC authenticates if either SPF, DKIM, or both pass and decides how to handle the message if it fails authorization.

Not all receiving serves will do a DMARC analysis before obtaining the message, but all the major Internet service providers (ISP) do. 

What are the benefits of implementing DMARC?

Some benefits of implementing DMARC include warranting domain reputation and security, email reliability, preventing email fraud, ensuring compliance, and more.

What is a DMARC record?

A DMARC record is a record published in DNS (Domain Name System) that informs email servers how to operate with unauthenticated emails and where to report email authentication statistics.

Do all email service providers support DMARC?

All major email service providers support DMARC, including Gmail, Outlook, Yahoo, Apple Mail, and AOL.
