DMARC is Domain-based Message Authentication, Reporting, and Conformance, a policy layer built on SPF and DKIM.
Example of DMARC
Example: DMARC tells receiving servers what to do when a message claiming to be from your domain fails SPF or DKIM alignment. It also provides reporting to help monitor abuse.
Why DMARC matters
It matters because email is one of the few channels a business can own directly. Strong email fundamentals improve trust, deliverability, segmentation, and long-term lead nurturing.
