Retrieve bounces by specific classification

API Overview

An email is considered bounced when the message is undeliverable and then returned to the server that sent it. Bounced emails can be either permanent or temporary failures to deliver the message.

For more information, see our Bounces documentation.

You can also manage bounced emails from the Suppression settings menu in the Twilio SendGrid App.
