Valimail has been tracking the usage of Domain-based Message Authentication, Receiving, and Conformance (DMARC) across tens of millions of domains since early 2017. During that time, we've seen consistent growth in DMARC usage and its overall effectiveness.
Now, for the first time, the number of domains with DMARC records exceeds one million.
