DMARC Readiness Checker

Resolves your DMARC, SPF and MX records live via DNS over HTTPS. DNS can tell you whether monitoring is configured, but only DMARC reports can tell you whether reject is safe.

Live DNS check via DoH. We resolve DMARC, SPF and MX records directly from Google's public DNS - no signup, no server.

Enter a domain above to see your DMARC, SPF and MX status

DNS queries go straight from your browser to Google's resolver. We never see what domain you check.

Heads up: this is a DNS-only check.

A clean DNS readout is necessary but not sufficient. The only way to know whether p=reject would silently break a real sender is to read your aggregate DMARC reports for at least 7-14 days. That is what the upcoming readiness platform will do.
