Mail Tracker 1.1 descriptions Mail tracker is a handy utility designed for Outlook Express users which sits in the tray & notifies you when the new e-mail arrives. It doesn' t require any setup & works straight out of the box. While Outlook Express already has You have new e-mail tray icon it doesn' t provide any information about incoming message. That proves to be distracting when there are many incoming e-mails & that' s why we have created Mail Tracker.
