Lead Designer

Not only is it helpful for communication purposes, but the project management features, collaborative workflow tools and customized add-ons make it great as a tool where every project can be seamlessly managed, without relying on too many apps.

Technical Support Engineer

There are many features I love about slack, such as the threads feature to categorize conversations, huddle feature to quickly hop on a call with colleagues, and the activity tab to see the latest activities to follow up and keep up to date with information.

Senior Director of IT

The leading instant messaging platform globally that combines chat, file sharing, video calling as a collaboration tool with hundreds of APIs with other corporate platforms.

Training and Development Manager

We were able to integrate our TrackVia account with Slack through Workato integrations, which allowed a discussion to start in a specific channel when a record was updated or added into a view in TrackVia.

Engineering

I love using slack This tool organizes team communication into focused, topic-specific channels, cutting down on email overload by consolidating discussions, files, and data in one place.

Customer Support

It allows us to share screens and call others when needed and we can even export channels to gather data for our teams.

I use slack literally everyday during for my work, where I direct message my colleagues, comment on threads, and keep up to date with channels and groups.

Corporate Recruiter

Within Slack, it provides you ability to create and save templates, to-do lists that can be shared with others within Slack

Founder, CEO

It also integrates very fluidly with other major software services such as Google Drive and Dropbox, so I can easily store and share files.

Medical Fronter

Being in a large team, the volume of my pings and channel alerts became overwhelming, leading to constant notifications and fragmented attention that actually decreased my deep-work productivity.

Software Analyst

The things that I disliked about the Slack are depicted below The important messages can sometimes did not get in focus, when there are too many active channels or notification popping out at the same time. When there is a large teams or active workplaces, messages from multiple channels ,threads , and direct message can become overwhelming making it difficult to focus on high priority conversations.

Full stack developer

The ability to quickly share files, schedule huddles, and track project updates makes teamwork much smoother. Despite minor drawbacks, it’s one of the best communication tools available.

Copywriter and marketing consultant

The design is really sleek, we rarely ever experience bugs or issues, messaging and creating group chats is easy and seamless, and scheduling meetings is also straightforward. Whenever I use any other softwares for this, I end up missing Slack.

Overall my experience with Slack has been great, it is a great tool to keep all team communication organized and clear, plus the customization, like the use of bots for scheduled messages, was a great tool to foster rapport amongst the team.

The best thing I like about slack is the connectivity through online chats, meetings and much more valuable tools that keeps my team connected and in touch!

IT Manager

Channels keep project work, on-call updates and support conversations organized, and scheduled messages help automate routine reminders.

Medical Assistance Specialist

I hate the notification overload when the shift is very busy and at times, there are bugs which makes me revisit the messages twice so that I am not missing anything important.

Integration with other software tools like Google Drive ,Zoom and other workplace apps are generally considered as a big advantage for me ,as everything can be managed from one platform .

Massage therapist

There are plenty of other software systems available that have mostly similar features and functionality, however I can say from first hand experience that Slack was reliable and consistent on many occasions where staff and management communication was critical in regards to client safety and navigating circumstances that absolutely could not wait.

Licensed Veterinary Technician

As a supervisor of my clinic, and a main communicator from my clinic to our sister clinics, it's exceedingly helpful so we don't have to tie up our own phone lines calling the other clinics.

Assistant Manager

Allows a regrouping of communications in one single software, allows the integration of other communication tools like Zendesk, and simplifies the collaboration on a daily basis

Copywriter

I think Slack needs to update their software to be in line with how most messaging systems work these days, where when you reply to a specific message, the reply shows that it's to that specific message. When you hit 'Reply' to a specific message in Slack, and you forget to tick the box 'Display in thread' , the reply only appears on the message wherever it was in the chat, starting a new thread.

Assistant to Founder

The ability to customize notifications, search message history, and use fun elements like GIFs and emojis adds both efficiency and personality to workplace interactions.

Medical Sciences Tutor

The platform’s user-friendly design and instant messaging capabilities enable swift and effective communication with underwriters, loan processors, and other teams, accelerating response times and decision-making.

Academic Tutor

Storing message history for later reference is valuable and team channels with features such as pinning messages, running polls, tagging teammates, and moving conversations into a message thread instead of the main message stream enable real-time and asynchronous information sharing while reducing distractions.

Program Coordinator

I appreciate the direct messaging, group messages, and integrations with other software like Google Suite that allows you to upload documents with a preview.

It’s a well-designed platform that balances structured discussions with casual interactions, helping teams stay connected without relying on endless email threads. While it can be overwhelming at times with constant notifications, adjusting settings and organizing channels properly makes it an essential tool for productivity and teamwork.

Deployment Strategist

On especially busy days, Slack can feel overwhelming. Despite its strong prioritization tools, the high volume of messages across multiple channels can create noise and make it harder to focus on deep work.

Apart from that , over the time ,teams may create too many channels ,which can lead to the confusion and make it harder for me to identify where specific discussions should takes place.

It allows us to set up specific channels for each loan file and client, centralizing all discussions, documents, and updates in one place, which reduces the chance of overlooking critical details buried in email chains.

It allows for structured conversations with channels, direct messaging, and integrations with productivity apps like Google Drive and Trello.

Partner, Digital

The most obvious is being able to communicate with either a client or a team member directly, send notes and files, have a quick voice call, and be notified of new activity. But I love that my email inbox counts are dramatically decreased and I can get caught up really quickly or search find something that I may have missed.

This was an extremely important and useful feature for the position and company I was at, at times when something was urgent it made a critical difference in timing to be able to call someone directly instead of sending a message they may not see right away.

Health Services Coordinator

My favorite aspect is sharing files. While some alternatives allow calls and chat, sharing files on them is very limited compared to what Slack offers.

Slack has become our primary communication support and assistance as getting urgent cases of medical assistance becomes relatively fast, without the need to use long emails and calls.

The ability to create channels for different topics, share files, and integrate with other tools really improved our daily workflow.

Web developer

The decision was driven by its affordability, accessibility, simple deployment, and powerful features such as threaded conversations and file-sharing bookmarks.

Teacher Success Manager

I think it's a little weird that my coworkers don't even have my phone number - but it's just not needed, Slack is sufficient. When we were testing a specific issue with our product, we made a Slack canvas to throw all the thoughts onto without clogging up the channel.

Director

Channels keep our conversations organized, and integrations with tools like Google Drive, Zoom, and Asana help us streamline workflows without ever leaving Slack.

Software Engineer

This is a great tool for student orgs or classes to collaborate with each other in teams and have group chats or 1:1 chats with individuals to communicate and bounce ideas off of each other.

RevOps Manager

You can also integrate many other software w/ Slack, such as Google Calendar, Google Drive, Box, Coda, Lattice, etc.
