How to Set Up DKIM for Sender?

October 12, 2023  |  < 1 min read

DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with. 

Steps to Configure DKIM for Sender

The DKIM is generated automatically by a tool created by Sender. In the “Settings” menu’s “Domains” branch, you may view SPF and DKIM values.

  • Sign in to Sender Console.
  • Select Settings.
  • Click on Domains now.
  • You’ll see a tiny screen.

  • Select Check SPF/DKIM records.
  • Save any changes you make to your record, then give your DNS 48 to 72 hours to take effect.
