Unsubscribes and Bounces

Unsubscribes and bounces are a part of the mass emailing process (as much as we all wish we could hit a 0% rate for both on every email we send).

Here in the unsubscribes and bounces archives you'll find the blog posts we've written about the unsubscribe process and bounce handling.

You may also be interested in our pages on GMass's unsubscribe management and bounce management features — see how GMass takes the burden off your hands and makes sure you only send to working email addresses belonging to people who want your emails.
