DomailfixDKIM record checker
DKIM signs your emails so receivers can tell they were not changed on the way. We look for keys under the selectors used by common email services, or the one you enter.
Questions and answers
What is a DKIM selector?
The name your DKIM key is published under, for example google for Google Workspace or selector1 for Microsoft 365. You can see it in a sent email's headers: DKIM-Signature: ... s=NAME.
How long should a DKIM key be?
2048 bits is recommended. 1024 bits still works; shorter keys are ignored.
