Slack is an excellent and powerful team messaging app with a rich collection of settings and options. It’s among the best, but it’s also the most expensive.

Summary

Slack was originally built as an internal communication tool for a game development company started by Flickr co-founder Stewart Butterfield in 2009. Launched publicly in 2013, it currently has over 12 million users in over 150 countries. We chose it as the best team communication software because it offers real-time messaging, feedback, and collaboration in a free, online platform.

Slack was developed to eliminate the inefficiencies and delays of email communication. The software lets users create channels that can be organized around a topic, team, project, or even a client. Channels can be public and open to all users of a Slack account or private and accessed by invitation only.

Besides communicating in real-time, Slack offers tons of integrations letting teams share files, create polls, schedule meetings, and connect to third-party project management, cloud storage, and productivity tools. The platform offers free, one-click voice and video calls and even lets users spin-off discussion threads to keep larger conversations focused and uncluttered.

One of Slack’s most useful features is its search function. No more sorting through emails or written notes hoping to find that one valuable piece of information. Slack lets users search for a conversation, mention, or user and share or bookmark it no matter how long ago it took place.
