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.

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.

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

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.

Corporate Recruiter

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

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.

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.

RevOps Manager

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

Senior Procurement Specialist

Generally nice way to communicate within teams and small companies. Though it's not the best solution for the big organisations, where many different chats, groups and teams are likely to be created.

There are just enough customizations and the integrations make the experience unique to your organization but familiar enough as you bring on new team members.

Load Management Supervisor

I love the ability to create different channels for specific projects or topics, and the integrations with tools like Google Drive, Zoom, and Asana are a huge plus.

Our team was in constant communication regarding client updates or concerns, as well as team communication for coordinating logistics and coverage.

Operations Lead

The instant communication, status updates, and ability to create focused channels make teamwork much smoother.

Software Developer

It really boost my collaboration, increase speeds up communication and helps team proper align across projects.

There isn't too much cons about slack, but I notice periodically some features with Slack can be down at times, such as slow search times, slow responsiveness and lag.

Executive Account Manager

There is a learning curve associated with utilizing advanced features such as Workflow, List, and Canvas. While these tools offer significant value, the initial appearance of complexity can present a barrier to adoption, making it challenging to achieve widespread user engagement.

Consultant

I hae the feeling the more updtes thy make the more clicks you have to go through to do a simple task, e.g. core features e.g. startigng a huddle is not as easily accessible as it used to be.

Investor

Moreover, it has lots of built in integrations, allowing you to connect it with Gmail, calendar and other zappier apps

High cost and free plan limits

With the free version of this product, the number of messages and images that can be saved on the server is limited which became quite a hassle in the ways that my organization used this product.

IT Support Associate II

Limit to the free plan of 10,000 messages and then you lose critical information then you have to pay for all users for an entire year to access more past data.

47% of reviewers feel negative about Slack’s pricing. Some users think the paid plans are expensive, especially for larger teams or organizations with tight budgets.

They also mention that alternative tools may offer similar features at a lower cost or as part of bundled software packages.

Overwhelming and inconsistent alerts

The mobile app notifications are really annoying as when 5 messages are delivered at once, it vibrates and pings 5 times in a matter of milliseconds instead of just once even when it's coming from the same slackbot or person.

Owner

I have the mobile version as well to receive messages on the go, however the notifications seem to be hit-or-miss. Although I'm always signed in to Slack on my phone, I don't always receive notifications of new messages resulting in my missing urgent requests.

Assistant Director

The ability to mute all notifications at once, seamless ability to tag others in messages, ability to make subgroups

You can send messages in the main group channel or even create separate chats for different people in a GroupMe to send messages pertinent to certain individuals.

The web interface previously allowed for multiple group chats to be displayed in one browser window.

Realtor

GroupMe is a dependable, no-frills group messaging tool that keeps communication simple and organized.

Direct messages are also available without having to exchange or keep personal cell phone numbers of every team member.

Tier III Technician

It's perfect for large groups, easy to use and has a good amount of features including, gifs, location, file/photo attachments and emojis.

However, it lack good media quality for attachments and there are security issues.

Business Analyst

Solid tool for managing large group conversations, but the interface feels outdated, and functionality is limited compared to modern alternatives like Slack.

What I like most about GroupMe is being able to notify my team of any changes to the schedule, if someone is running late, if an incident occurs, etc.

Admin

We also love using it as a tool to give reconization to employees

You can connect with people you know, find groups to join or create a group like myself from my child’s sports team

Lacks some of the more advanced features found in other messaging apps

Sales Manager

Group me allows me to stay in conversation with so many different groups all at the same time.

Company Owner

It's an awesome software to use whether I'm chatting with a group or making conference calls to go over business plans.

I don't like how if you leave a group you never intended to join, it is still tied to your account and you can't remove it from your history.

It is a good place to create a group chat without having to give out your phone number like in a message chat

GroupMe is a simple, effective group messaging platform.

If i can change the notification sound and it when you delete a message it still shows the group you deleted something.

Fitness Instructor

Maybe like a catalogue of chat names and pictures that I click on to open the thead.

Fleet Supervisor

We have a management team that's spread out over multiple states and we can easily keep each other updated in this one spot.

Coach

Excellent app for communication and sharing information with students or peeps.
