DMARC Record Checker
Check how your domain handles unauthenticated email.
What this test checks
Record syntax, policy, subdomain policy, percentage, reporting destinations and SPF/DKIM alignment modes.
Why this matters
DMARC is the principal public control for the visible From domain. Receivers can still make their own policy decisions.
How to fix common problems
Use p=none while reviewing reports, then increase enforcement only after legitimate mail aligns.
FAQ
Does p=reject force every receiver?
No. It requests rejection from DMARC-compliant receivers; the final decision remains with each receiver.
