Providing the Delegate Sender with the Identity Information for Amazon SES Sending Authorization
After you create your sending authorization policy and attach it to your identity, you need to give the delegate sender the Amazon Resource Name (ARN) of the identity. The delegate sender will pass that ARN to Amazon SES in the email-sending operation or in the header of the email.
You can use the following procedure to find your identity's ARN.
To find the ARN of an identity
Sign in to the AWS Management Console and open the Amazon SES console at https://console.aws.amazon.com/ses/.
In the left navigation pane, under Identity Management, choose either Email Addresses or Domains.
In the resource list, choose the identity to which you attached the sending authorization policy.
At the top of the details pane, after Identity ARN, you will see the identity's ARN. It will look similar to arn:aws:ses:us-east-1:123456789012:email@example.com. Copy the entire ARN and give it to your delegate sender.
