The article provides a step-by-step tutorial on how to configure DKIM for Zendesk. Setting up DKIM for Zendesk will help emails pass DMARC alignment and will also contribute to improving your domain reputation among ISPs that will ensure fewer chances of your emails being marked as spam.
Log in to your Zendesk account
Navigate to Admin > Channels >Email
Navigate to “Custom domain for DKIM”. Here you will find 2 CNAME records to be added to your domain’s DNS for selectors zendesk1 and zendesk2
The two CNAME records would appear as zendesk1._domainkey.yourdomain.com pointing to zendesk1._domainkey.zendesk.com and zendesk2._domainkey.yourdomain.com pointing to zendesk2._domainkey.zendesk.com
Log in to your domain registrar’s management console
Publish the two CNAME records in your domain’s DNS
After the records are published in your DNS, head back to Zendesk and simply click on the “Enable” checkbox in the “Custom domain for DKIM’ section
Click on Save to create your custom domain for DKIM on Zendesk
With this, you have DKIM set up for Zendesk successfully.
