Each year, 10 to 25 percent of the Internet users change their email address. Removing obsolete email addresses from your list based on bounceback error messages is a time consuming and dreadful job.

The "bounceback handling" feature intercepts bounceback error messages and automatically processes them on your behalf: a bounceback report is generated and obsolete email addresses are removed from your contacts database and moved to a separate "bounced" list that can be viewed and exported.
