The solution is to unsubscribe from as many of them as you can afford, and start subscribing to RSS readers.
Pretty simply way to keep your inboxes clean and only get deluged with information, not just promotions.
Get a Bloglines RSS reader, start subscribing to some quality content blogs, stop reading other people's promotions, errr, I mean emails and your days and night will be more productive.
