How to Set Up DKIM for Help Scout?

DKIM is an email authentication system that uses two cryptographic keys: a public key published in a Domain Name System TXT record and a private key encrypted in an outgoing message signature. The domain owner is the one who generates both keys. This way, it can be checked if the mail is authentic or forged.

Enabling DKIM authentication on Help Scout

  • Go to your DNS and make the following changes in your DNS records

  • Create two CNAMEs ( and strong1 and strong2 has been used as examples, replace your domain and desired selector names with it)



  • And point them (1) and (2) to the following




  • If the CNAME cannot be created, please contact Help Scout support for additional details

  • It takes 24-48 hours for changes to take effect.

  • Once DNS settings are completed, head over to the Help Scout mailbox and navigate to Settings > Outgoing Email and click on the Test Settings button.

  • If all the settings are properly configured in DNS, the DKIM status indicator will change to active.

Additionally, lookup and validate your DKIM record using a free DKIM record lookup tool to ensure that your DKIM CNAME records are devoid of errors and fully functional.
