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, and while your record is still p=none the drift shows up as spoofed mail slipping past DMARC instead of showing up in your report. DMARCit watches the record and the aggregate reports continuously, so drift shows up in the worklist instead of a customer complaint. Free trial, no card. See how continuous monitoring works →
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.
