A DMARC record is not the same as DMARC protection. That distinction has been clear to anyone who works in email authentication for years, but EasyDMARC’s 2026 DMARC Adoption and Enforcement Report, drawn from an analysis of 1.8 million domains across the Fortune 500 and Inc. 5000, makes the gap impossible to dismiss. Of the 938,000 domains that have published a DMARC record, only about 9 percent – roughly 159,000 domains – combine an enforcement policy with aggregate reporting. The other 91 percent have a record. They do not have protection.
