DMARC stands for Domain-based Message Authentication, Reporting and Conformance.

It is a protocol that was built on top of the existing protocols SPF and DKIM. 

DMARC does a few things:

1. It takes into account the results from SPF and DKIM 

2. It requires not only for SPF or DKIM to pass but for the domain used by either one to also align with the domain found in the From address in order for DMARC to pass. For more information on what identifier alignment is please click on the button below.

3. Reports SPF, DKIM and DMARC results back to the domain found in the From address (ie. sender).

4. Finally tells receivers how to treat emails that fail DMARC validation by specifying a policy in DNS.
