DKIM Record Lookup Tool

DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain is authorized by that domain's administrators.

A DKIM record is published in your domain's DNS as a TXT record at [selector]._domainkey.[domain]. The selector is chosen by your email service provider and is required for proper authentication.

Common selectors include default, google, selector1, selector2, but they can be different depending on your email service provider.
