How to Set Up a DKIM Record for Intercom?



DKIM is used to detect forged sender addresses in emails. It confirms that an email was sent from an address authorized by the owner of the domain where it was sent. Clubbed with SPF and DMARC, DKIM can help protect your domain against phishing attacks and domain spoofing activities.  


Intercom sets its address as your default outbound address while sending emails. This is the same address that is displayed in the From: field of your messages. You can however change this to configure your emails to be sent from a custom domain to display your brand name instead. Let’s find out how to do that!

Setting up your custom domain on Intercom

To send emails from Intercom using a custom domain: 


  • App Settings > Outbound > Addresses & domains


  • Simply click on Add a custom address


  • Enter the name and email address

  • Click on the Confirm button


Verifying Your Domain using DKIM for Intercom

When your custom domain on Intercom isn’t authenticated with DKIM email authentication, it looks something like this: 



To set up DKIM on Intercom: 


  • Log in to your Intercom application

  • Go to app settings 

  • Visit the Email addresses & domains page

  • On this page, you will find 2 CNAME records generated by Intercom


 


  • Copy and paste the records in your domain’s DNS 

  • Give your DNS time to process the changes. Then log back into your Intercom account and click on verify authentication



Intercom strongly recommends you configure a DMARC analyzer for your domain to improve your sender reputation and prevent spam. Sign up for a free DMARC trial today!
