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.
This endpoint allows you to retrieve a specific bounce by email address.
Bearer <<YOUR_API_KEY_HERE>>The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.
