Newsletters: Bounce Management« Usage
In a few easy steps (see the navigation to the right) you can configure your WordPress Newsletters plugin to receive bounce messages and act on those bounce emails in order to help you keep your mailing list(s) clean at all times.
There are three different bounce methods available. While the email piping with an alias to Perl (CGI) script allows more control, we strongly suggest using the POP/IMAP mailbox bounce method since it is the simplest and is fully automated. The Amazon SNS method is only available when you are sending emails through Amazon SES.
