Gdow is a lightweight portable application that runs quietly in the Windows system tray. It will check the Gmail inbox sporadically and notify the user when new mails have arrived. The gmail mail notifier will display the current unread mail count of the Gmail inbox in the system tray and even display mail previews when hovering over the system tray icon.

The gmail mail notifier has to be configured before it can be used. Among the required settings are the Gmail username and password. The user can configure the type of information that are displayed (object, summary, sender’s name and address), the way it is displayed (messagebox, popup balloon, transparent form).

It is furthermore possible to change the mail check interval and enable sound notifications for new mails. The system tray icon contains a link to the Gmail inbox. The way the inbox is opened can be configured in the options as well. Among the options are the possibility to open the inbox in the default web browser or default email client.

Gdow uses roughly 12 Megabytes of computer memory while running. The Gmail mail notifier will run on most Windows operating systems including Windows XP and Windows Vista.
