I love that you can have multiple conversations at once, so if someone sends me something urgent it doesn't get lost in my inbox with other emails/texts! The ability to reply from your phone is fantastic as well because sometimes people send texts or messages when they're not even online which makes them difficult for me to respond back without having to check their phones first (which isn't always possible). Sometimes there are glitches where you don't know what time zone everyone is talking about until after you've replied since some of us live across different countries. Make sure to set up notifications before sending out any large files otherwise it could be really frustrating waiting around while everything gets downloaded over again. This has helped solve all our communication issues by being able to communicate more easily throughout the day.
