Providing Information to the Identity Owner for Amazon SES Sending Authorization
As a delegate sender, you need to give your AWS account ID or the Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) user who will do the sending to the identity owner. You can find this information by using the following procedures.
To find the ARN of an IAM user
Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com/iam/.
In the left navigation pane, choose Users.
In the resource list, choose the user name. The Summary section displays the ARN. The ARN will look something like arn:aws:iam::123456789012:user/John.
To find your AWS account ID
You can go directly to https://console.aws.amazon.com/billing/home?#/account. Alternatively, you can navigate to it by going to the AWS Management Console at https://console.aws.amazon.com/. In the top bar, select your name, and then select My Account.
Expand Account Settings. The AWS account ID is at the top of this section.
