Overall Satisfaction with Slack

We use Slack as our primary internal communication tool. Dedicated channels are created for teams, projects, and emergencies where appropriate, and we heavily leverage integrations within Slack to send routine notifications on different events across our tech stack. Examples include sales activities in Salesforce, updates on JIRA tickets, and project updates from Asana, just to name a few.

Pros

  • Threads. The ease in which you can manage conversations via threads makes it easy to manage multiple conversations simultaneously
  • Integrations. Slack's easy to use API and deep set of integrations makes it a very powerful tool
  • The ability to create internal/external workspaces that can allow us to interface with customers and external stakeholders all through the same platform

Cons

  • While the Google Calendar integration is nice, it would be more optimal if it could also share details of the kind of meeting the user is in through a hover cue, or something like that
  • It would be nice to some AI functionality added to the message composer for scripting routine kinds of messages
  • Having a repository of messaging templates that you could also leverage when needed would be a real quality of life improvement
  • Slack has facilitated greater communication between teams and an overall reduction in project silo'ing
  • It has had a positive influence on our average handling time for customer inquiries by allowing agents and reps to get the help they need when they need it
  • Slack has also facilitated upsell opportunities that have contributed directly to our revenue team closing opportunities they would have otherwise missed
Extremely intuitive. The layout of Slack is easy to understand with clear visual cues for all of the most commonly used tools. I've never felt like it was confusing to use. Menus are not overly cluttered, and so long as you manage your channels well (I divide my various channels into sections for easier management), then it's quite a powerful tool. I'd also appreciate the ability to prioritize certain DMs so that you can respond most readily to priority contacts.
Microsoft Teams is one of the other tools that I've evaluated in a professional context. Compared to Slack, it feels a bit clunkier and bland. Slack feels vibrant and full of personality that can vary from workplace to workplace. Teams is also a far more expensive solution to utilize and ties you to the Microsoft tech stack, which comes with its own set of challenges. Discord, while great for the more fun/social use-cases, also involves having to pay for subscriptions like Discord Nitro to be able to fully leverage all of its chat related features. Which is an annoying user tax that just doesn't exist with Slack.

Do you think Slack delivers good value for the price?

Yes

Are you happy with Slack's feature set?

Yes

Did Slack live up to sales and marketing promises?

Yes

Did implementation of Slack go as expected?

Yes

Would you buy Slack again?

Yes

I can't think of a more effective and versatile tool to use for internal team communications. Slack has a track record for reliability that competitors like Teams can match. It is also relatively easy to use, quick to learn, and has a lot of features that can scale with your team over time. I've used Slack at many companies over the course of my career and I have yet to find a case where it hasn't been able to meet the needs of my team.
