After reading this Lifehacker article, I'm questioning my use of filters in my email. I have two separate GMail inboxes, one for my school/work account at my university, the other for my personal account. I get a fair amount of email in both, probably 60+ a day in the former, 20+ a day in the latter, and this is over and above the rules that prune things out of the inbox into separate folders (like, say, "politics" or "Psych 220").
A problem I've noticed is, even on the weeks when I'm really good about inbox zero, I'm really haphazard about going through those separate folders, so I'm looking for a good heuristic about when I should and when I shouldn't do this.
My best guess is that if it's a topic that has anything that could be important, that I might need to see or act on on a daily basis, don't filter - just process the inbox like usual. But for stuff that isn't - say, like, Groupons - filter and make a task to remind me to check them on occasion. But this is just a guess. Any tried-and-true methods?
