Twenty years later, I'm releasing an open source email app that helps you reach inbox zero for a single day: Simple Email Mode

Simple Mode makes handling less overwhelming:

* Handle emails in batches of 5

* Long emails summarized

* Timer to gamify maintain focus

* Set aside what you want to handle later. Archive the rest

You can try it completely free at https://getinboxzero.com under the Early Access tab.

Only for Gmail users at this time.
