What is a DMARC Record?
A DMARC (Domain-based Message Authentication, Reporting, and Conformance) Record is an email authentication protocol that builds on SPF and DKIM to enforce policies for handling unauthenticated emails. It also provides reporting capabilities to monitor email activity.
DMARC enables domain owners to define how receiving mail servers should handle failed authentication checks.
What is a DMARC Record used for?
DMARC is used to prevent email-based attacks such as Phishing, Spoofing, and Business Email Compromise (BEC). It improves visibility into email traffic and helps organizations detect abuse.
Organizations implement DMARC alongside SPF, DKIM, and BIMI to strengthen email security and improve trust in communications.
