Free DMARC Record Checker
DMARC builds on SPF and DKIM alignment and tells receivers how a domain wants unauthenticated mail handled. This checker queries _dmarc for the domain, parses policy and reporting tags, and flags missing or multiple DMARC records.
How to use it
- Enter the public domain you want to inspect.
- Run the DNS check and review the published email configuration returned by the authoritative DNS path.
- Use the findings together with the related SPF, DKIM, DMARC and MX checks before changing production email DNS.
How to read the result
Policies commonly progress from p=none for monitoring toward quarantine or reject for enforcement. Reporting addresses can provide visibility, but a strong DMARC posture still depends on correct SPF/DKIM alignment for legitimate senders.
Limitations
This tool inspects the published DNS policy; it does not send test mail or prove that every legitimate sender is aligned. Change enforcement only after understanding your real sending sources.
Frequently asked questions
What is p=none in DMARC?
It requests monitoring without asking receivers to quarantine or reject failing messages, and is commonly used while collecting data.
Is p=reject always better?
It provides stronger enforcement, but enabling it before legitimate senders are aligned can cause valid mail to be rejected.
