I know some of you "loathe" gmail, so if you do, skip this. For those that use it, there is a terrific addon called boomerang that you have to get. Basically if an email comes in, and you want to keep your inbox clean and deal with it, say tomorrow, you just boomerang it with 1 click and the choice of "tomorrow" from the drop down menu. You can of course select any time even up to weeks or months, or just a specific date. The email is kept in a gmail folder, and when its the date you set, it appears in your inbox again. You can even set a boomerang to send an email on a specific date. Then when you click send, it will hold the email in the boomerang outbox until that day you selected. I've only been using this tool for a 2 weeks, but already its a "can't live without" Everyday i have a clean inbox, and anything that i'm too busy to deal with today, i just quickly boomerang it till the weekend where i catch up on everything. Check it out here.
