Test your DMARC record

Enter your domain and abr.cloud reads its DMARC policy — the rule that tells the world what to do with mail that fails your checks — and explains, in plain language, whether you're actually protected and what to change.

One quick verification, no account. We store nothing unless you start monitoring.

What is DMARC?

DMARC ties SPF and DKIM together and tells receiving servers what to do when a message fails: nothing (p=none), send it to spam (p=quarantine), or reject it outright (p=reject). It also sends you reports of who is sending mail as your domain. Without DMARC at enforcement, anyone can spoof your exact address.

Frequently asked questions

Is the DMARC test free?

Yes — free with a quick CAPTCHA, no account. It reads only public DNS.

Is p=none enough?

No. p=none only collects reports; it tells receivers to do nothing, so spoofed mail still gets delivered. Move to quarantine or reject once your legitimate senders pass.

What do I need before p=reject?

A working SPF record and DKIM signing, both aligned with your From domain — check those first, then tighten DMARC.
