DMARC record checker

Enter a domain to read its DMARC record: the policy for mail that fails authentication, where reports go, and what to change next.

Free, no signup. The lookup runs in your browser through public DNS resolvers (Cloudflare 1.1.1.1, Google as a fallback); Skrap.ai doesn't receive the domain.

What DMARC does

DMARC is a TXT record at _dmarc.<domain>. It tells receivers what to do with mail whose From domain fails SPF and DKIM alignment, and where to send reports about it. Gmail and Yahoo require a DMARC record from bulk senders.

TagWhat it sets
pPolicy: none (monitor), quarantine (spam folder) or reject
ruaWhere aggregate reports are sent (mailto: address)
spPolicy for subdomains, when different
pctShare of failing mail the policy applies to
adkim / aspfAlignment: relaxed (r, default) or strict (s)

A safe path to enforcement

  1. 1Publish v=DMARC1; p=none; rua=mailto:[email protected] and collect reports for a few weeks.
  2. 2Fix every legitimate sender the reports show failing (add it to SPF, turn on DKIM signing).
  3. 3Move to p=quarantine, then to p=reject once reports stay clean.

Frequently asked questions

What is a good DMARC policy?

p=reject gives the most protection; p=quarantine is a solid step on the way. p=none only monitors: failing mail is still delivered, so it doesn't stop spoofing on its own.

Where is the DMARC record stored?

In a TXT record at _dmarc.<domain>, for example _dmarc.example.com. Subdomains without their own record follow the parent domain's sp= (or p=) policy.

Do I need DMARC to send cold email?

Gmail and Yahoo require SPF, DKIM and a DMARC record from bulk senders, and a DMARC record helps any domain's reputation. Pair it with list hygiene: verify addresses before sending to keep bounces low.

Why don't I get DMARC reports?

The record needs a rua=mailto: address. If the address is on another domain, that domain must also publish a record authorising it to receive your reports.
