Why tame emails at all ? Have a public email and private email, keep private email for limited use only. Use public email for bill pay, subscription etc. Use gmail, they do a good job categorizing spam, junk emails etc. When you see spam email, just hit unsubscribe and move on.

Every year I create DMZ folder and move all the email from inbox to DMZ. This way I can search old emails when I need but my inbox gets a clean start.
