Email notifier for multiple email accounts

I'm very sure that all you guys out there were having more than one email accounts.
There are lots of free email services available and it might be weird to have only one email account on these days.

On the other side, it's really waste a lot of time to directly log in to every email account you have. And I had found three email notifiers to make life easier.

1. Gmail Notifier
The original notifier for Gmail. Supports checking multiple accounts as well as Gmail Hosted accounts. Allows you to monitor multiple Gmail accounts right inside your browser's UI.

2. Gmail Manager
Allows you to manage multiple Gmail accounts and receive new mail notifications. Displays your account details including unread messages, saved drafts, spam messages, labels with new mail, space used, and new mail snippets.

3. WebMail Notifier
WebMail Notifier checks your webmail accounts and notifies the number of unread emails.
You can use multiple accounts in a same host. Currently supports Gmail, Yahoo, Hotmail/MSN/Live and many more.

I personally prefer WebMail Notifier, because it support different email service.

Do you have other email notifier better than my list?
