Handling Bounces and Complaints
When you uses SES Simple Email System from AWS you need to manage:
- bounce backs
this is required by Amazon to protect your reputation, so Amazon IP /or your domain won't get blacklisted.
Amazon SES assigns a unique message ID to each email that you successfully submit to send. When Amazon SES receives a bounce or complaint message from an ISP, we forward the feedback message to you. The format of bounce and complaint messages varies between ISPs, but Amazon SES interprets these messages and, if you choose to set up Amazon SNS topics for them, categorizes them into JSON objects.
