In TrustRadius reviews, Slack is a foundational communication tool for Information organizations, enabling real-time exchange across distributed teams and critical for project management. Its robust integration with essential tools like Google Drive and Salesforce is highly valued, streamlining data flow and reducing context switching. Organized discussion channels are crucial for maintaining clarity in complex project-based work and preserving institutional knowledge.

Reviewers also value automated workflows for reducing administrative overhead and Huddles for rapid, ad-hoc decision-making. However, limitations exist, particularly concerning search functionality, which 3 of 16 reviewers found challenging for efficient information discovery. Concerns about thread management, performance issues, and call quality also impact productivity. Overall, Slack significantly enhances operational efficiency and collaboration for Information professionals, despite these areas for improvement.


  • Seamless integration with critical information management tools like Google Drive and Salesforce
  • Structured communication channels for organized project discussions and knowledge retention
  • Real-time collaboration features (e.g., Huddles) for rapid decision-making in project workflows
  • Automation capabilities for streamlining routine administrative tasks for information professionals
  • Facilitates continuous connectivity for distributed and hybrid information teams
  • Suboptimal search functionality impacting efficient information discovery and retrieval
  • Challenges with thread management affecting conversation clarity in complex projects
  • Performance issues including high resource utilization and slow application response
  • Inconsistent call quality affecting the reliability of synchronous information exchange

Slack is essential for getting work done

Rating: 9 out of 10
Incentivized

Use Cases and Deployment Scope

We use Slack for internal communications across teams, and also for automated chats from other platforms we integrate with (ie. Salesforce sending deal updates and reminders for in-flight opportunities). We also have many external connections set up to discuss with partners, customers, and prospects during active and post - evaluations.

Pros

  • Ease of Use
  • Mobile Access
  • Notifications
  • Clean UI

Cons

  • Color customization
  • Integrations

Likelihood to Recommend

Slack is best suited for teams to communicate across internal use cases such as team chats, peer groups, or 1:1 messaging. I've also enjoyed them adding functionality to connect with external users such as prospects, customers, and partners. We use it to glean information from other partners of ours about potential cosell and in flight opps.

Good for start ups and tech companies

Rating: 7 out of 10
Incentivized

Use Cases and Deployment Scope

we use Slack as our main form of messaging and we pretty much replace emails with Slack the majority of the time we have different channels for different programs campaigns and purposes we use direct messages on there and we use the huddle feature to have quick and short meetings and sometimes regular team updates we also host on Slack as it is much easier than setting up a Google meet meeting and much quicker. We also use Slack to integrate with house spot to ensure we don’t miss any alert on deals and customer and marketing Leeds

Pros

  • Messaging
  • Communication
  • Notifications from other tools
  • Meeting

Cons

  • The thread is quite hard to follow
  • Dm is right at the bottom so it’s hard to find sometimes
  • People get deleted off the dm list after a week or so.

Likelihood to Recommend


I think Slack is more suitable for smaller organisations and startup maybe below 50 employees anything above I think it would be quite difficult for communication communications you would want to track things a bit better so you might want to use Microsoft team

Slack Is a Wonderful Communication and Productivity Tool

Rating: 8 out of 10
Incentivized

Use Cases and Deployment Scope

As a distributed team with employees in the US, Hong Kong, mainland China, India and Thailand we need to all be able to communicate bot synchronously and asynchronously. Slack affords us that ability. And when we can't all meet up on Google Meet or Zoom due to time differences, Slack is a good alternative to create groups that effectively are ongoing meetings. Also, the ability to tie into Google Drive and Figma is useful as well.



The only downside is that conversations, replying in threads, etc. can create missed conversations as the complexity increases. We recommend allowing users to keep it simple so that trying to go back and find specific info in a thread is easier. Search helps but can create even more noise.

Pros

  • Allow for asynchronous conversation across the planet
  • Allow for uploading changes in Google docs/sheets, presentations
  • ability to see when a collaborator is online

Cons

  • As noted, the threads can lose conversations and make it hard to find the information you're looking for
  • Creating vast numbers of groups of users can be challenging to navigate

Likelihood to Recommend

As noted, for distributed teams Slack is essential. That way team members working on their time-zone can communicate valuable information while other team members are sleeping or off and they can then see it the next day.

Slack

Rating: 7 out of 10
Incentivized

Use Cases and Deployment Scope

Our team is fully remote. We use Slack daily for team members to communicate with one other. We integrate Slack with our platforms api to monitor workflows and alert if things fail. We also use it for interdepartmental communication, such as support team working reporting issues to the dev team or management pushing out directives to the broader team.

Pros

  • Team Communication
  • Archival of historic messages
  • Integration with API to monitor key workflows that happen on the backend of our application

Cons

  • Integration of conversation or huddle conversation summarizing technology
  • Potentially a chat bot we could use to query based on previous conversations in different Slack channels (i.e. How can I respond to a customer that is asking about upgrade opportunities, or discounts for specific billing arrangements)

Likelihood to Recommend

It is great for interdepartmental communication between various groups of people. It is essential for collaboration via features like Huddles. It is also really useful for archiving past conversations and communication between teams. It could be better by allowing for some ai integration as well as some more advanced whiteboarding tools on huddles while screensharing like marking the screen as a participant for other participants to see, or the ability to capture some or all of huddle conversations and screenshares, and quickly share and export it to other channels or conversations.

Slack review after 4 years

Rating: 9 out of 10
Incentivized

Use Cases and Deployment Scope

- Corporate chat
- Corporate communication
- Corporation organization of key documents that must be easily accessible by everyone (i.e.: HR policies)
- Triggered communication regarding product development processes (i.e.: new PRs, critical errors)
- Communication and coordination of key initiatives (one Slack channel for each key initiative)

Pros

  • Corporate chat
  • Corporate announcements
  • Triggered communications

Cons

  • The reply feature: sometimes information get lost and people don't always know how to use it (discoverability problem)
  • Message preview sometimes can be clumsy with a lot of space being used and the preview is not valuable enough
  • New messages in some channels can get lost because the UI visual clue is just too subtle (the bold of the letters are usually not enough)
  • You can not define a standard view for everyone. So key channels for corporate communication are not always easily accessible (meaning they do not occupy a prime location on the interface)

Likelihood to Recommend

Appropriate:
Corporate chat, corporate communication, communication and coordination of initiatives, triggered communications between a lot of tools, compliance and security.

Less appropriate:
You want to foster audio and video communication, you want to replicate a office-like feeling, you do not want to spend a lot of money on a communication tool.

Slack is our email substitute

Rating: 9 out of 10
Incentivized

Use Cases and Deployment Scope

Slack has become our primary source of communication within our organization. Whether it is quick communication, scheduling projects or discussing key work it is the primary surface area our remote team goes to get work done. In addition to communication, it becomes a key place to find relevant information (including documents and past decisions).

Pros

  • Organizes communication at high volume (large teams)
  • Makes it easy to have real time discussions
  • Integrates with a large suite of tools to help connect work (like Jira/Figma) or automate work flows (forms and checkins)

Cons

  • Slack with video integration - While its easy to start Zoom, I would love to see integration from chat in a call into threads in Slack
  • DMs to channels are a little rigid. It would be great to have a more fluid way for DMs (private messages) turn into channels to be more inclusive.
  • Notification permissions have gotten much better, but having more granular notification control by channel would help reduce noise
  • The DM UX is being pushed heavily - I personally feel the homescreen organization is much easier to navigate (wish I had control to say more in this view vs the new state).

Likelihood to Recommend

- Great for organizing communication and managing projects - especially for remote teams. Its extremely flexible for integrations and bringing in external parties into conversations.

- While its decent, Slack is likely not the best option for video conferencing. There are other tools that are better suited, especially with the AI tooling for recording and summarizing.

Slack is the only reliable app for workplace comms and collaboration

Rating: 10 out of 10
Incentivized

Use Cases and Deployment Scope

We are a Slack-forward company. Most comms run through Slack with a minimal reliance on email (internally). We're able to keep our many working groups centralized and communicate company-wide while being spread out across many locations. We are a fully remote company.

Pros

  • Keeps working groups well organized with a central platform for necessary files
  • Allows teams that aren't centrally localized to effectively communicate
  • Keeps a running history of all communications in one place allowing frequently asked questions to be asked via search

Cons

  • It doesn't make sense that the same keyboard commands that are universally accepted aren't that way in Slack. I should be able to use the same keyboard command to link out a word to an external site or doc that I use everywhere.
  • Sometimes search is unintuitive and poorly organized.

Likelihood to Recommend

There really isn't a better workplace communication app. Especially with teams that are stratified across locations. If you're looking to decrease reliance on email and the constraints of how email systems store data, Slack is the only way to go.
