MailSense monitors your email accounts and lets you know when you have mail by popping out a notification from the side of your screen. It also displays the number of messages in your system tray. Move your mouse over the indicator and a pop-up hint will tell you which accounts have mail. Double-click the indicator and your default email application will be launched. Filter mail by sender or subject to block spam. SSL capability built in so you can check your secure accounts as well. 30-day trial.
