11 Best Free Online DKIM Record Checker Websites

Here is a list of the best free online DKIM Record Checker websites. DKIM is short for Domain Keys Identified Mail. It is an email authentication technique. This technique is used to verify that an email is sent by the domain owner. An authentic mail will have a digital signature i.e., a DKIM signature. By checking the DKIM record of a domain, a receiver can verify the authenticity of the email received.

The DKIM signature is not visible to the end-users. Thus, you need a DKIM Checker tool to validate that on a server level. A DKIM Record Checker takes the domain URL along with a selector (s1, s2, email, etc.). The selector indicates where the public key portion of the DKIM key pair exists in DNS. To prove the authenticity, the DKIM check must return with a valid DKIM Key record. This post covers 11 websites with a free DKIM record checker tool. You can check these out in detail below.
