DMARC Checker

The Untangled Labs DMARC Checker retrieves and analyzes the DMARC TXT record for any domain. It validates record syntax, reports the policy level (p=none, p=quarantine, p=reject), checks SPF and DKIM identifier alignment requirements, identifies rua and ruf reporting addresses, and flags misconfigurations. Use it to audit email security posture or verify DMARC setup before tightening enforcement. Free, no account required.
