Great article, Ellen! As a solopreneur, I've tried many apps myself as well. I adore Slack! Isn't that funny. Mostly because email is such a waste of time, what with all the back and forth, etc. and I don't trust FB to keep client details private, PLUS I can easily find anything easily with the Search button, whereas with email, good luck lol (and yes, I've tried many email apps, too!).

Looking forward to more helpful articles!
