DMARC, SPF & DKIM Checker

Check a domain for email authentication records that help prevent spoofing and phishing.

Domain to check

Only the entered domain is sent to the server so DNS records can be queried.

SPF lists the servers allowed to send mail for a domain.

DMARC tells receivers what to do when SPF or DKIM alignment fails.

DKIM signs mail so receivers can detect tampering and verify the sending domain.
