See who is sending email as you.
DMARC reports arrive as zipped files full of server addresses. Drop them in and we’ll tell you which services send as you, which of them pass the checks, what looks fake, and whether it’s safe to tighten your settings.
Not getting reports yet? Check your domain first: it shows whether reports are switched on.
Files are opened and read in your browser and never uploaded. To name the services, only the sending servers’ addresses are looked up.

Where the reports come from
- Who sends them
- Google, Microsoft, Yahoo and other large email providers send a daily summary of every email they received that used your domain.
- Switching them on
- Your DMARC record needs a reports address (rua=). The email health check shows whether yours has one and gives you the record to add.
- Which files to use
- The .zip or .gz attachment on each report email. The reader doesn’t accept failure reports or saved emails, because those can contain the content of real messages.
- What we see
- Nothing from the files themselves. They’re read on your device. Only the sending servers’ IP addresses are looked up, to put names to them, and they aren’t kept.
