What is a DKIM DNS record?

DomainKeys Identified Mail (DKIM) is an authentication standard used to prevent email spoofing. Specifically, DKIM attempts to prevent the spoofing of a domain that’s used to deliver email. DKIM employs the concept of a domain owner who controls the DNS records for a domain.

How do I get DKIM?

Steps to set up DKIM
  1. Generate the domain key for your domain.
  2. Add the public key to your domain’s DNS records. Email servers can use this key to verify your messages’ DKIM signatures.
  3. Turn on DKIM signing to start adding a DKIM signature to all outgoing messages.

How do I verify DKIM?

You can check/validate your DKIM record by using our DKIM record Checker.
  1. Enter ‘Google’ as the Selector. As an example, we’re using a generated domain key from Google Apps.

The DKIM-Signature has expired on the message and will result in a DKIM FAILURE result at all inboxes. This expiration tag (“x” tag) is found in the DKIM-Signature headers of outbound messages.

Is Dkim better than SPF?

DKIM is crucial for cold email as well since it also acts as a key of sorts. It’s not a key to sending emails like SPF, but a key to opening them. DKIM is an invisible signature that ISPs use to form a reputation score, so your email is less likely to end up in the spam folder.
