What is DMARC?

DMARC is an email authentication system that protects your organization’s domains from spoofing, phishing, and other cyber attacks. It builds on the widely deployed email verification techniques, SPF (Sender Policy Framework),and DKIM (Domain Keys Identified Mail).

What does DMARC Stand for?

DMARC is an acronym for Domain-based Message Authentication, Reporting, and Conformance. As the name suggests, it authenticates emails to confirm whether it meets the verification standards, and also reports on the same.

  • It increases security by preventing phishing attacks from being sent under your domain name without your knowledge.
  • It lets you enforce stricter rules for email sending such as requiring authentication on all messages or banning attachments from being sent via email at all unless they’re authenticated first
