We are G2 Winter 2026 Leader for DMARC Software

DMARC (RFC 7489) ties SPF and DKIM together by requiring alignment between the envelope sender and the visible From header. According to Google’s February 2024 bulk sender requirements, a DMARC policy of at least p=none is now mandatory for any domain sending 5,000+ messages per day to Gmail users.

DMARC is the only email authentication protocol that gives you both enforcement and visibility, says Brad Slavin, General Manager of DuoCircle. SPF and DKIM authenticate silently - DMARC tells you what happened and lets you control the outcome. That combination of reporting and policy is why DMARC adoption is accelerating.

See why IT and security professionals around the world trust DMARC Report to simplify DMARC management and strengthen email security.
