Check your Gmail messages without opening your browser
The Gmail Notifier is an application that alerts you when you have new Gmail messages. It displays an icon in your system tray to let you know if you have unread Gmail messages, and shows you their subjects, senders and snippets, all without your having to open a web browser.The Notifier is in beta. Before you download it, we encourage you to review the system requirements and privacy information.
If you have the Google Talk client installed, you will automatically receive new mail notifications from Google Talk and you do not need to install the Notifier.
