Frequently Asked Questions
What is a DKIM selector?
A selector points to the public key record for a signing service, which lets you publish multiple keys and rotate them over time.
Why do some selectors show a provider hint?
Common patterns like google, selector1, or k1 often map to known email platforms, so the detector can suggest a likely provider.
Why might no selectors be found?
The domain may not use DKIM, may use uncommon selector names, or may publish keys on a different subdomain or service.
