20 Telegram Alternatives to Chat With in 2024
Slack works more like a forum than Teams does – falling somewhere in between a forum and a chat software. It lets you organize discussions into different channels, as well as by thread. You can invite others into a thread by @mentioning them, and it lets you add lots of different types of content. Slack works really well for 1:1 audio meetings, “huddles,” that give you the...
Why we switched to Mattermost
Now, obviously core messaging functionality is critical. Mattermost is great there, but so is Slack. In fact, Slack features like third-party integrations and threaded messaging were missed greatly (thank you, Mattermost, for recently adding threaded messaging). So the relative parity between the solutions from a ‘speeds and feeds’ perspective was table stakes, but we...

Microsoft Teams Vs Clariti: Which one should you choose?
The main reason behind the sudden rise of Teams is it is being offered at no added cost to Office 365 users. This strategy paid for Teams as it was able to increase its market share and overtake its potential rival Slack in no time.

OpenPhone Reviews

  1. Easy to use, and just what we needed!

    I needed a 1800 number for my business, and paying for a second phone line and getting a second phone is overpriced for what I needed. for 10 bucks a month, OpenPhone allows me to have a 1800 number right on my own cell phone through their app. So my personal calls don't get mixed up with my business calls. The app is easy to use, has a voicemail feature, and call forwarding for when I'm out and don't want to use data.

    👍 Pros:    Easy to use|Cost effective
