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!
