Some friends and I actually pitched this idea to YC and got an interview a few years ago. We didn't get in.

Part of the issue is as soon as you describe this idea one of the thoughts people will have 'so you want to pay me for receiving spam.'

Twitter is an example of an 'alternative inbox' but the hard nut to crack is to get enough people using a system like it in lieu of email. If that is not achieved, all you end up with is two inboxes with a bunch of junk in them, or at a minimum the same amount of email you always got.
