DMARC Record Checker

Why DMARC is no longer optional

Since 2024, Google and Yahoo require DMARC for bulk senders, and Microsoft followed for high-volume domains in 2025. In 2026, sending cold email without DMARC means immediate deprioritization — often straight to spam regardless of content quality.

Reading your result

• p=none — monitoring mode. Legitimate while you collect reports, but weak as an end state; receivers factor policy strength into reputation.
• p=quarantine — failing mail goes to spam. The right target for most outbound teams.
• p=reject — failing mail is refused outright. Strongest signal; adopt once alignment is verified clean.
• rua= — where aggregate reports go. Without it you have zero visibility into spoofing or alignment failures.

FAQ

Where does the DMARC record live?

A TXT record at _dmarc.yourdomain.com, starting with v=DMARC1.

Do I need DMARC on secondary sending domains?

Yes — especially there. Outbound teams typically run lookalike domains to protect the main brand; each one needs its own SPF, DKIM and DMARC to inbox.
