DomainKeys Identified Mail (DKIM) is a method for email senders to digitally sign email messages in a way that can be verified by email receivers. This allows receivers to verify that the message truly came from the sender, and has not been tampered with. DKIM is intended to address some of the flaws in the existing email system, such as spoofing, phishing, and message tampering. 

When sending emails, Intercom uses its address as the default outbound address. This is the same address that appears in your mails’ “From:” field. However, you may modify this to set up your emails to be sent from a custom domain and display your company name in place of the default. Let’s understand how.

How to Configure your custom domain on Intercom

Using a custom domain, Intercom users can send emails by following the steps:

  • Go to App Settings > Outbound > Addresses & domains
  • Click on “Add a custom address
  • Simply insert your name and email address.
  • Select “Confirm.”
