DMARC record checker
See your domain's DMARC policy — what receivers do with mail that fails SPF or DKIM, and where reports go.
What is DMARC?
DMARC ties SPF and DKIM together. It tells receiving servers what to do when a message claiming to be from your domain fails those checks, and where to send reports about it.
Start safely
Begin with p=none and a report address. Once the reports show your real mail passes, move to quarantine, then reject.
