Top 5 Slack alternatives that you should consider in 2020

Companies have increasingly invested in technology and tools to enhance workplace productivity. Slack has benefited from this trend as a provider of workplace messaging software that increases productivity by cutting down on unwanted emails. However, Slack users have now realized that emails are an integral part of an organization and it cannot be replaced solely by chat messages. 

In addition, complex integration issues with add-ons, high cost of ownership, and the “noise” created by frequent chat messages in Slack channels has made the ‘email killer’ a ‘productivity killer’.  

As per a finding by RescueTime, when Slack was down for a few hours on June 27, 2018, productivity increased! If the NPS and product-market fit scores of Slack are anything to go by, it is noticeable that a sizable segment of the user base is looking for alternatives.
