20 Best Free Slack Alternatives for Team Communication / Collaboration

Communicating with a team is one of the most essential aspects of a business, but emails are more of messages via machine instead of people. During the early years of emails, the messages were mostly office related or from friends or family. But, in the recent times, the automated emails from social media updates or newsletters for marketing are creating all the mess. Thus, communicating with the team via emails may affect the team productivity with all the clutter. In fact, there are better options for communication these days.

Slack, launched by the Flickr founder in 2013, is one of the most popular apps for team communications in the current times. It’s compatible with both desktop, laptops, and mobile platforms. This app offers a much improved and convenient way for team communication internally. It also features an API that allows you to look for the entire conversations based on the situation. The best part about Slack is its partnership with applications like Google Docs, DropBox, ZenDesk, GitHub, etc. that makes it a great way to communicate within the team.
