Interactive intelligence tool

Run the check, then ship the workflow

Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.

Start with the live form

Enter a domain, URL, IP, email, or record and get a focused result without setup.

Review decision-ready signals

Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.

Automate the winning workflow

Use the request and response examples to turn a one-off check into an API call or recipe.

Frequently Asked Questions

What do DMARC policies none, quarantine, and reject mean?

They state the domain owner's requested handling for messages that fail DMARC. None requests monitoring, quarantine treats failures as suspicious, and reject requests rejection.

Why is no DMARC record found?

A valid DMARC TXT record may not be published at _dmarc for the domain, or a recent DNS change may not yet be visible to the resolver used for the check.

Does a valid DMARC record mean every email passes DMARC?

No. The record defines policy. A message passes DMARC only when an authenticated SPF or DKIM identity aligns with the domain in the From address.
