Setting up DKIM for Zendesk will help emails pass DMARC alignment and improve your domain reputation among ISPs that will ensure fewer changes of your emails being marked as spam.
 
  1. Login to your Zendesk account.
  2. Navigate to the Admin Center > Channels > Email
 
 
 
  1. Navigate down to "Custom domain for DKIM". Here you will see 2 CNAME records to be added to your domain's DNS for selectors zendesk1 and zendesk2.
  2. The two CNAME records will appear as zendesk1._domainkey.yourdomain.com pointing to zendesk1._domainkey.zendesk.com and zendesk2._domainkey.yourdomain.com pointing to zendesk2._domainkey.zendesk.com
 
 
  1. Login to your domain registrar's management console and publish the two CNAME records in your domain's DNS. Below is an example on how these records should be entered.

  1. After the records are published in your DNS, head back to Zendesk and simple click on "Enable" checkbox in the "Custom domain for DKIM" section.
  2. Click on Save to create your custom domain for DKIM for Zendesk
 
 
  1. You can then verify your message is passing DKIM by sending yourself a test message and analyzing the header of the message.
