Email authentication tool
Is someone faking email from your domain? Find out in 60 seconds.
Free check. No signup. Plain-English result.
This is a snapshot. Real domains change under you.
The checker read your _dmarc record right now. Tomorrow a marketing vendor rotates an IP, or someone adds a survey tool nobody told IT about. At p=none that mail fails DMARC quietly and only shows up if someone reads the aggregate reports; at quarantine or reject it lands in junk or bounces. DMARCit reads every aggregate report as it arrives, so drift shows up in the worklist instead of a customer complaint, and your domain page re-checks the record itself. Free trial, no card.

How this works
The checker looks up the public TXT record at _dmarc for the domain you enter, parses common DMARC tags like p=, sp=, pct=, and rua=, then summarizes what to fix or improve next.
