READING THE RESULT
Public evidence, carefully described.
Registration data
Displayed exactly as the authoritative RDAP provider publishes it. Redacted fields stay redacted.

HOW TO READ THIS TOOL
What the DMARC check means
The checker requests TXT records at the domain's _dmarc hostname and looks for a policy beginning with v=DMARC1.
- Shows whether a policy is published
- Does not validate every policy mechanism
- Email administrators should verify enforcement carefully
