A global look at how DMARC adoption is progressing from monitoring to enforcement, and whether organizations and their users are truly protected.
Global DMARC adoption continues to grow, but meaningful enforcement still lags behind. In this 2026 report, EasyDMARC analyzes DMARC policies across the top 1.8 million domains worldwide, along with the Fortune 500 and Inc. 5000. The findings show a clear maturity gap: large enterprises are moving further toward enforcement, while many high-growth companies remain stuck in monitoring-only mode.

Publishing a DMARC record is no longer the real benchmark. The more important question is whether organizations have moved from monitoring to enforcement. This report shows where adoption is rising, where enforcement still lags, and which segments are making the most progress toward meaningful protection
See year-over-year growth in valid DMARC records across the top 1.8 million domains, and how organizations are progressing from initial deployment toward stronger policies. EasyDMARC found that valid DMARC adoption grew from 523,921 domains in 2023 to 858,782 in 2025 and 937,931 in early 2026.
Explore the maturity gap between large enterprises and high-growth companies. Fortune 500 adoption reached 475 out of 500 companies, with more than 80% at enforcement-level policies, while Inc. 5000 companies showed strong adoption but slower progress toward enforcement.
DMARC adoption has become widespread, but adoption alone does not guarantee protection. Across the global domain ecosystem, many organizations have implemented DMARC records to satisfy technical requirements or maintain deliverability, yet have not progressed to policies that actively block spoofed email. The report shows that the next stage of DMARC maturity depends on helping organizations move beyond monitoring and toward stronger enforcement.
The contrast between the Fortune 500 and the Inc. 5000 makes this especially clear. Large enterprises are more likely to have the operational maturity, visibility, and internal resources needed to transition toward enforcement, while many fast-growing organizations remain cautious because of complex email infrastructures and multiple third-party sending platforms.
EasyDMARC analyzed DMARC records for the top 1.8 million domains globally by visitor traffic, as well as companies listed in the Fortune 500 and Inc. 5000. For each domain, we identified whether a valid DMARC record was present, classified the policy as p=none, p=quarantine, or p=reject, checked for RUA aggregate reporting, and compared 2023, 2025, and early 2026 snapshots to track adoption and enforcement trends over time.
