Email DNS checker

Inspect public MX, SPF, DMARC and selected DKIM records before setting up domain email.

Ask your sending provider for the DKIM selector. A domain alone cannot reveal every DKIM key.

What do these records tell me?

MX identifies the receiving mail servers. SPF lists authorized sending services. DKIM publishes a signing key under a provider-specific selector. DMARC publishes a policy for authentication alignment.

Finding a record does not prove it is configured correctly or that a message will arrive. This check does not inspect private inboxes, change DNS or activate email.
