I liked that it was easy for me to use with my Gmail account! It's very simple to set up and even easier to use once you have everything down pat. There were some times when I would get an error message but this didn't happen often. The only thing that I disliked about EMOs was that sometimes there wasn't much of an explanation on why something happened so I had no idea what to do next time around. So far all has been good though. I've just started using it recently in order to help keep track of emails coming into our business inboxes from people who are not part of our team.
