I’ve been a web-mail kinda guy since a long time ago. I ditched my email clients (Mail, Entourage, and Thunderbird) and prefer to keep my GMail handy on any computer (or sometimes cellphone) that I use, wherever I am. But Postbox might just change my mind.

This free open-source mail client (available for Mac and Windows) combines few great features that can help users manage their emails better.
