Mail Unread Menu is a simple menubar application which can provide you with a quick and easy way to see how many unread email messages are in Apple's Mail. Unlike other menubar notification applications, Mail Unread Menu is actually a plugin for Mail.app, which means that the count is instantaneously updated whenever you recieve new email or change the status of a message.
ANONYMOUS Not sure what is going on but this update doesn't appear to work at all. The application is running, mail us running, unread mail is sitting in 2 folders but Mail Unread Menu doesn't tell me there is new mail? Running Tiger 10.4.11 (Version 3.0.1)
