DMARC Checker
A domain's DMARC policy in plain English.
The name you type is looked up by our server and sent back to you; it is not stored.
Type a domain such as gmail.com, a full web address, or an IP address for a reverse (PTR) lookup.

How to use DMARC Checker
- Type the domainType a domain such as example.com, a web address, or an IP address.
- Choose recordsLeave All common records, or pick one type such as MX or TXT.
- Read the resultsSee every record with its time to live, and the SPF and DMARC checks for mail domains.
The lookup is set to DMARC. It reads the TXT record at _dmarc.yourdomain and explains the policy (none, quarantine or reject), the subdomain policy, the percentage applied, the report addresses and the alignment mode. If there is none, it shows a safe first record to publish.
How it works
DMARC Checker is a web page. The name you type is looked up by our server and sent back to you; it is not stored. There is no account and no sign-up; to keep it quick for everyone, each connection has an hourly limit, well above normal use.
Moving to reject
Run p=none for a few weeks and read the reports. Once every legitimate sender passes, move to quarantine, then reject.
