SendGrid requires special configuration actions outside of Authenticate. Please follow these steps to complete configuration for SendGrid, and then return to your automation-guided task list in Authenticate.

1. It is not necessary to add SendGrid as an 'Approved Sender' because the service uses a dedicated subdomain which will be delegated to SendGrid servers. SendGrid will then publish an SPF record on that subdomain.

2. Sign into your SendGrid account and generate CNAME records for SPF and DKIM by following these steps:

  • In the SendGrid UI, navigate to Settings->Sender Authentication
  • In the domain authentication section, click Get Started
  • Pick your DNS host from the list, enter your domain and click Next
  • Three CNAME records will be generated, one is used for delegating SPF to SendGrid for the chosen subdomain and two DKIM keys

Note: You can find more detailed information about the setup process here:

3. Publish the first CNAME record in your DNS, this will allow SendGrid to publish an SPF record for the selected subdomain.

4. Add the two DKIM keys in Authenticate, by clicking 'Add a DKIM key' from the DKIM management section. Enter the selector name, CNAME target value and associate the keys with SendGrid.

5. Go back to the SendGrid dashboard, navigate to Settings->Sender Authentication->Domain Authentication, click on your selected subdomain and verify the records.

6. Once you have completed these steps, you can begin sending authenticated email using SendGrid.
