To restore e-mail to an ally rather than a curse.
Tactically at a personal level
Tip 6: get off all lists; you know you are not reading them
Tip 7: set up every filter and rule you can to get rid of spam/re-route for info only; find the guy who understands them to help you
Tip 8: don't use threads
Tip 9: batch process your e-mail i.e. decide a couple of times a day ONLY to check e-mail and then
Tip 10: handle once only: action it/file it/delte it.
BTW, tips 1-5 are here.
