USB Webmail Notifier
If you think email notifiers such as the Gmail Notifier don’t alert you of your webmail well enough, you’ll want to take a peek at this USB Webmail Notifier. This gadget works in the background and will inform you when you’ve got new mail by illuminating itself in blue, red or green. Each of the colors can be assigned to a different email client. If you’re wondering how it is able to know whether you’ve received email or not, you’ll have to bear in mind that this notifier handles the email authentication for you, so if you’re quite fussy about privacy, you’ll need to take extra care with it.
