Email might not be dead just yet, but it’s certainly heading in that direction — enter office messaging apps.

Since instant messaging first arrived in the late aughts, it has almost entirely replaced email in most contexts. One area where email managed to hang on was in the workplace. All that changed with the arrival of Slack.

The popular messaging app for teams allows them to communicate instantaneously with one another, without the need for lengthy and complicated email chains.

Of course, popularity breeds imitation and now there are dozens of workplace messenger apps vying for attention.

The trouble is that while each of them offers something largely similar, all have subtle nuances. It can be tricky for business users to know which one to pick.

Considering very few of them have a meaningful free version, it’s important to pick the right one, lest business owners waste money.

Verdict selected five of the most popular business messaging apps to decide which is the best one overall.

We scored each of the five out of five in nine categories. The best in each category got five points, the second best got four points, and so on. We used these scores to calculate an overall score, using all the available data. We converted this score into a percentage to get an average approval rating. Here’s the services, ranked worst to best and the features they include.

It’s worth saying that our approval rating, while we’ve tried to be as objective as possible, is partially based on personal opinion. Each of these services offer something slightly different so do think about what your business really needs.

Microsoft Teams – 66%

Microsoft Teams is part of a whole suite of Microsoft-created business tools. It contains emails, Microsoft Office, Skype, Yammer, and more.

Still, it’s a comprehensive package that’ll see you through basically everything.

Flock – 73%

The best thing about Flock is that it’s one of the cheapest business messaging apps. It also focuses its attention on the messaging app side of things. The other features of the app include multi-party video conferencing, audio bridge, screen sharing, to-do list that can be shared between a team, polls, reminders, mailing lists, guest account management for vendors, and multiple integrations for project management, developer tools, marketing tools, and even social media, to track your company pages in real time.

Slack – 73%

Slack is popular for a reason, and that reason is that the free version is fairly comprehensive. Aside from some extra video-calling capabilities and the ability to share screens, Slack’s free version does it all. That said, like Flock, it is just a messenger app, not anything fancy. Still, it does the job and with thousands of plug-ins and add-ons, it really can be customed to whatever your business needs are.

Google Hangouts Chat – 75%

The newest of the business messenger apps. Google Hangouts Chat actually just launched a few days before we came to research this piece. Google Hangouts Chat is, like Microsoft Teams, part of a suite of office tools, G-Suite. This includes Gmail, Google Drive, Google Docs, and various other apps.

Workplace by Facebook – 82%

Workplace by Facebook does, of course, have an entire chat system built in, but it’s so much more. The application is also a social media platform for business. Essentially, Workplace is Facebook only it’s grey instead of blue, and administrators have fully access to everything to what their employees post. Considering how many people use Facebook proper, most people will have an intuitive understanding of it. The only downside is that it’s paid, and obviously Facebook itself is free. If you like the system, you could very well just use Facebook itself to do the same job; it just depends on whether or not your employees are happy to befriend each other using their personal accounts.

$1-3 per month.

Free version?

3 month trial.
