- Easy to install - Comes complete with a quick-start guide (really helps) - It's FREE - Nice easy to use GUI - Works like a dream! - Choose between having desktop alerts when your emails are opened, or receive email notifications (or both!) - You can set the desktop alert timeout (or have it stay there), handy if you've walked out the room for 5 mins, for example. - Sound notifications
Nothing of any significance.
All in all, this is a great program, it really works! Highly recommended!
