My Outlook filtering is good, my problem is I get about 150 junk emails a day and I'm tired of going through them to see what I need in there (usually 2-3 a day).
I like gmail as well. When I was at Iowa State, it was easy to navigate back and forth between my Cymail and my primary account since Cymail is run off of Gmail. It’s the same thing the school I’m getting my master’s at does as well.
