This will be brief.
Inbox zero is a valuable thing to maintain. Roughly promoted around the web as having an empty inbox.
An email inbox collects a few things:
- junk
- automatic mail sent to you
- personal mail sent to you
- work sent to you
- (maybe - work you send to yourself because that's the best way to store information for now)
- Old as all hell (or other friendly name)
- 2014
- 2015
- 2016
(system sounds really good)
How many emails are you getting per day + per year for each of the addresses?
