From the developer:
ActiveTracker is an optional program which allows you to automatically add tracking to the emails you send.
Active Tracker affects all sending addresses used by the email clients you configured the plug-in to work with. The default is for 'all' compatible email and webmail clients, but you can choose the ones you want it to track.
