From DNS record to answers in three steps
Add your domain
Paste one TXT record into your DNS. We generate a unique reporting address for you.
We collect the reports
Mailbox providers send us your DMARC data. We parse and aggregate it automatically.
You get answers
A clear dashboard and email digests show what's healthy, what's not, and how to fix it.
Every source scored, so you know what to ignore
Each sending source is classified — Authenticated, Partial, or Unauthenticated — so you know at a glance what needs attention. Drill into any source → IP → message group for the exact remediation: a custom Return-Path for SPF alignment, or a DKIM key to sign with.
