Free for one domain

Find out who is sending as you.

A scan tells you how your records are configured today. Aggregate reports tell you who has actually been using your domain, which is the question that matters.

1. 01

   Publish two DNS records

   A DMARC record pointing reports at us, and a verification TXT record. We generate both, and you paste them into your DNS.

2. 02

   Reports start arriving

   Every major mailbox provider sends aggregate reports on their own schedule. The first usually lands within 48 hours.

3. 03

   Sources get classified

   Each sender is identified and sorted: your own infrastructure, an authorised third party, a forwarder, or something that should not be there.

You can export everything and erase the account at any time. Forensic samples are redacted before they are written, so we never hold your recipients’ data.
