I'd like to have a Gmail notification service in my Epiphany indicator applet, without leaving Evolution open in the background all the time. Right now I only get notifications if Evolution is open. Strangely, this is not the case with Google calendars in Evolution -- evolution can be closed yet I still get applet notifications through the clock/calendar applet.
Gmail Notifier is probably the best option for what you are trying to accomplish.
I use CloudSN (Cloud Services Notification). It supports gmail, google reader, pop3, imap, twitter, identi.ca

The best part is that it supports multiple accounts.
I've had good luck with CheckGmail. Has a nice GUI, cool toaster popups, and allows you take actions on emails from the tray.
sudo apt-get install checkgmail; checkgmail &
Check out GMailWatcher. It is still in early development stage, but works quite well. I am using it for over a month now. Recommended.
