Google has released a Mac OS X version of their Gmail Notifier. This handy little app puts an envelope icon at the top of your monitor on the system bar that turns blue when you receive mail. It also lets you know how many unread messages you have waiting. (This is a preference setting you can turn off if you don’t like it.)

If you click on the envelope, you get a drop down menu that shows you who sent the message and its subject line. You can jump right over to the new mail (that opens in your default browser) or wait till later.

To start using Gmail Notifier, download the app, drag it to your Applications folder, double-click it, enter your Gmail info, then restart (or log out and back in). The envelope will now appear at the top of your monitor.

And it works great. Nice to see a Mac version of this helpful tool…
