Gmail is undoubtedly the best web-based email around. Unfortunately Google doesn't have any Gmail notifier for Linux. However thanks to the open-source world there are many alternatives out to choose from and whats better is that all of them are better than their windows counterparts and are free. Here is a list to help you chose one.
1. Gmail Notifier: Gmail Notifier is the first one which comes to mind. It resides in your task bar and displays a pop up when a new mail drops by. It also shows a short snippet of the mail so you can decide whether you want to check it out right now or not.
