EasyDMARC 2025 DMARC Adoption Report

Content by: Heather Scaglione from EasyDMARC

The EasyDMARC 2025 DMARC Adoption Report analyzes global email security trends, showing how DMARC implementation and enforcement have evolved. Drawing from phishing data in 7 countries, domain analysis of Fortune 500 and Inc. 5000 companies, and a survey of 980 IT professionals, the report highlights key security shifts from 2023 to 2025.

Global DMARC adoption rose from 27.2% to 47.7%, with enforcement policies up 50%. Countries with mandatory DMARC, like the US, saw phishing success drop from 69% to 14%, while non-enforcing countries like the Netherlands saw rates rise to 97%. The report reveals a gap between monitoring-only (p=none) and enforcement policies—over 508K domains monitor only, versus 350K using active enforcement. Enterprise size also impacts adoption, with larger firms better positioned for full implementation. The findings underscore that enforcement, not just adoption, is key to reducing phishing risk and improving email security.
