Slack review

Last updated:  

It’s highly reviewed and feature-rich, but charges more than many of its competitors.

Slack is a business app that helps streamline communications across company teams and projects. Its free service tier offers video calls, direct messaging and dedicated project channels. But you’ll have to upgrade to a pricey paid service tier for more file storage and app integrations.

  • Choose this software if you have employees who work from home or want to streamline communication at your company.
  • Consider something else if you need access to shared channels, but can’t afford $8 for each employee monthly.

Slack’s features

Slack’s channel feature is its bread and butter — and a staple among Finder employees both in the US and across the globe. Share threads across internal teams and external clients with integrated file sharing:

  • Dedicated channels. Organize channels by project, team or topic and loop team members into the conversation for updates in real-time from everyone in the channel.
  • Privacy settings. Pivot confidential conversations into private channels with invited team members.
  • Direct messaging. Chat one-on-one with single team members through direct messaging.
  • Searchable history. Scroll up through a channel to see what’s been shared or search by keyword across direct messages and company-wide channels.
  • Video calls. Share your screen and chat face to face with video conferences for up to 15 team members.
  • Automated procedures. Expedite work tasks with Slack workflows — automated actions that include daily reminders, status updates and help requests.

Slack pricing and fees

Slack service tiers are available monthly, but discounted rates are available for those who pay annually.

How does Slack work?

Slack is a messaging application that helps teams build collaborative online workspaces. Slack channels help organize company-wide communications into sub-categories, while direct messaging allows for more intimate one-on-ones. The app can be used for both in-person and remote work.

Slack’s offerings can be overwhelming for beginners, but the platform is designed to scale based on the role and responsibilities of each team member. Subcontractors and part-timers may only be looped into a few channels, while supervisors and team leaders may have their finger on the pulse of 10 or more threads.

What I think about Slack

I’ve used Slack as a member of the Finder team for nearly three years, both as a part-time freelancer and a full-time staff member. Personally, I’m a big fan. I can pop onto Slack to check in with my manager, see what other teams are up to and share what I’m working on for real-time feedback.

And if I’m in the writing groove and don’t want to be disturbed, I can pause notifications until I’m ready to tackle them, enabling me to work undisturbed and catch up when I’m ready.

Pros and cons


  • App integration. Slack integrates with 2,000 apps across a variety of categories and industries, including data analytics, developer tools, project management, marketing, sales and finance.
  • Monthly billing. No contract is required and you can terminate your service with no cancellation fee.
  • Free service tier. Slack’s basic offerings — the messaging platform, video conferencing and app integrations — are available for free.
  • Learning database. Slack’s comprehensive learning library includes articles that can help you navigate both beginner and advanced platform features.


  • Expensive. Slack’s more sophisticated features come at a cost — its monthly membership fees are higher than many of its competitors, including Flock and Mattermost.
  • No phone support. Tech support is limited to 24-hour email inquiries and live chat support for Standard plans and up from 2 a.m. to 9:30 p.m., Monday to Thursday and 2 a.m. to 5 p.m., on Fridays, PT.

Slack reviews and complaints

As of October 2020, Slack receives high marks from its customers. With only 1 complaint in the last three years, its Better Business Bureau (BBB) page isn’t much to go on. But on Trustpilot, Slack boasts a TrustScore of 4.4 out of 5 based on 124 reviews.

Among the high notes are Slack’s many app integrations, screen sharing and search features, while a handful of customers complained that the software is difficult to pick up for fresh hires.

Bottom line

Slack helps in-person and remote workforces organize communications with dedicated channels, one-to-one direct messaging and a generous sweep of app integrations. But it’s pricier than many of its counterparts and may be challenging for newcomers to master.
