About the DKIM Record Lookup

Fetch the DKIM public key for a given selector and confirm it is published and well-formed, so signed mail can be verified by receiving servers.

• Selector-based lookup for any domain
• Validates key format and flags
• Confirms the record is reachable before you go live

Frequently asked questions

What is a DKIM selector?

A label that identifies which key to use, published at selector._domainkey.yourdomain.com. Your mail provider tells you which selector it signs with.

Why is DKIM failing after a provider change?

The new provider signs with a different selector and key, so the old record no longer matches. Publish the new one they supply.
