Delegate Sender Tasks for Amazon SES Sending Authorization

As a delegate sender, you are sending cross-account emails. This means that you are sending emails on behalf of an identity that you do not own, but are authorized to use. Even though you are sending on the identity owner's behalf, bounces and complaints count toward your bounce and complaint metrics, and the emails count toward your sending quota. You are also responsible for requesting any sending limit increases that you might need to send the identity owner's emails.

Delegate senders are responsible for the tasks described in this section. To see where these tasks fit into the overall sending authorization process, see Overview of Sending Authorization.
