I hope you have heard of Slack. Because everyone (at least in the tech, personal development, and business world) has. It’s evolved into a replacement for email between people who want to talk to each other in a company. The problem is that email gets really messy when the conversation starts getting long. You have to dig through tons of nested emails to find what you need. Plus, sending documents, attaching files, or communicating with a group of people makes it worse. Slack solves this by being something in between email and instant message. Messages and files sent to a group of people or a single person are neatly organized and clear as day. On top of that, there are customizations you can add to make it your own. You can have it alert your phone with the app or pull up a GIF if you're feeling funny.
