DMARC Instructions

What are DMARC Records?

DMARC (Domain-based Message Authentication, Reporting & Conformance) makes it easier for Internet Service Providers (ISPs) to prevent malicious email practices, such as domain spoofing.

This allows for email senders to specify how to handle emails that aren’t authenticated using SPF or DKIM.
