Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an authentication method designed to stop bad actors from impersonating you. DMARC acts as an “identity card” to mail servers and inbox service providers (ISPs), allowing both to validate the sender’s identity to prevent cybercriminals from spoofing emails.

Logistically, DMARC is a line of code that goes into your DNS TXT record. It works with other authentication protocols like SPF, DKIM, and BIMI to validate and protect your sender identity.
