    This app has become extremely helpful at work. It has decreased the amount of emails we send each other

    Positive

    I love that I can create channels for each client and send messages, flag messages, and save messages

    Great for Teams

    Date: Nov 12 2020
    Summary

    Slack is a professional brand that is consistent and reliable for me and my company's needs. I would definitely recommend them to any small-medium size business.

    Positive

    Easy way for me and my team to communicate. We can share files and even connect Google Docs to make sharing a bit easier. Never many issues with maintenance and always reliable!

    Negative

    Honestly, not much that I can think of that I don't like.

    Significant instant message platform

    Date: May 27 2020
    Summary

    I send quick messages to my clients through it and Slack helps in pinning chats for others who may not be on shift right away. This gives me freedom to do more positive things.

    Positive

    It is very easy to use along with user friendly approach. I also appreciate its facility to discuss important things with others.

    Negative

    Nothing specific to dislike but one can easily distracted from his work by reading hundreds of messages received.

    Slack app is great

    Date: May 13 2020
    Summary

    If you want to simplify your communication to one application, I think Slack would be a great app to do so.

    Positive

    The Slack app is awesome. I really like being able to connect different apps to my Slack channel (such as Google Calendar, Dropbox, etc.). It makes it much easier to balance a busy schedule!

    Negative

    I have only had issues with using trying to integrate some apps into my Slack channel, but most of the issues are due to the app itself, not Slack. So no cons from me!

    Lots of people love it and use it everyday, not right for me.

    Date: Apr 06 2020
    Summary

    My previous company used this for day to day communication so everyone could chat independent of any specific medium but I never really got into it. Maybe they have come a long way since then but it wasn't right for me. Lots of my team members loved it though.

    Positive

    Device agnostic is a bonus and for people who use lots of different communication mediums it is ideal.

    Negative

    Just another chat to monitor and mostly duplicates of things you need to read elsewhere and with more features elsewhere.

    Slack Streamlined my Contractor Communications

    Date: Nov 11 2020
    Summary

    I can't believe Slack is free. It's an excellent communication product that my team and I use every day to manage very detailed projects.

    Positive

    I run a remote digital marketing & graphic design business. That being said, there are a lot of details that go into instructing graphic & web designers on how to make the client happy. Slack gives us the ability to communicate on different channels segmented by project and then when the project is done, we can archive those inactive channels. Slack allows for text, images, bulleted & numbered lists, and is overall way better than email & text.

    Negative

    Some people feel that Slack is overwhelming, and I understand that if you go overboard with the number of channels you have, then it would be. It's very important to manage the number of channels you have, then the tool is excellent.

    A must communication tool

    Date: May 23 2020
    Summary

    Overall, Slack is a great software for team management and collaboration. You can easily manage multiple teams/projects on it and share files with other team members. It is a cross-platform software that means you can use it from any platform and from anywhere.

    Positive

    I love Slack and have been using it for almost 1 year. It is easy to use and simple. Slack makes team communication easy for you. It gives you features to make different channels for different teams. I am a freelance software engineer so I need to use many tools like Jira, Drive, and Calendar, Slack performs a key role here because it has a feature to add all these extensions. I can easily access them from a single platform named Slack.

    Negative

    I don't have anything to write as a con about Slack. It is great software and I don't face any problem with it yet.

    Positive

    I love the ease with which Slack integrates with all other office systems. The UI is super user friendly and very easy to learn and use.

    Negative

    I have to say I didn't like how long you can wait on customer service sometimes. Not all the time. Just on some occasions you can wait quite awhile.

    Great Business Communication Tool

    Date: May 24 2020
    Summary

    Overall Slack is really one of the best tools for business today and my company has been using it for over a year now and we are impressed how it improved out workflow and handled communication with ease. Highly recommend it for any business looking for a tool to improve their communication needs.

    Positive

    Slack can be used on various platforms that can be deployed on Windows, Mac, Android and iPhone which provides your entire team a great way to communicate on various devices. It provides really great tools ranging from file sharing, video conferences and chatting in real time. We have used this tool in our business for over a year now and everyone is very happy with the results that are provided. It helps us work better and best of all it keeps all of us organized.

    Negative

    Not everything in the world is perfect, there are times if you have a lot of messages can be a bit hard to search for a certain message or if you have lot's of rooms to get everything categorized. Notifications can sometimes arrive pretty late depending on the device you are using.

    Best tool to improve productivity

    Date: Dec 09 2020
    Summary

    Overall, with Slack, you get a quite good and intuitive user interface so that you can exchange messages, however, they should provide more messages in the trial version.

    Positive

    You get a lot of support and help from the inbuilt chatbot.
    Emojis and custom emojis make the chats a lot more fun and interesting with the members.
    You get a ton of tools and features to increase your productivity and helps you in your growth.

    Negative

    They should provide more features in the free version so the user can try the application thoroughly before opting for the paid version.

    Using Slack for two years now to keep in touch with my team

    Date: May 23 2020
    Summary

    Our company has a large team that is spread across the world and using Slack can be so useful when staying in touch with them. It is really great to have one single tool that I can use to send messages, share files, have video calls, and share my screen. Once you get used to it and are familiar with its full potential the sky is the limit for you. I strongly recommend it to people to try it and master it. It can be a really fun and satisfactory experience.

    Positive

    The pros that I can think of are as follows
    1. Slack Bots: We keep track of operations inside our company (server health, script updates, entertainment(we have a joke bot in our company)) using bots.
    2. Dark mode: The dark mode is a real godsend when you are working for long hours because staring at a white screen for long periods can be stressful.
    3. Emojis: The wide array of emojis and the option to create custom emojis which are specific to your company make conveying your thoughts easier and in making your conversations a little light-hearted.
    4. Channels and threads: The ability to create channels and threads is really valuable when you want to communicate with a larger group.
    5. Multi-platform: Slack works on browser, has a marvelous web app, and a pretty great mobile app so it is easy to stay in touch with your colleagues irrespective of the platform you are on.
    6. File sharing: Sharing files is very easy and is just a simple drag and drop and you can send almost any type of file to your colleagues.
    7. Code indenting: Sharing a snippet of code with fellow devs can be really easy and intuitive thanks to the code indenting feature.

    Negative

    There are very few cons that I can think of but here are a couple.
    1. Lack of a read feature: You can’t know if your recipient has read your message or not. It would be nice to have a blue tick sort of feature like you have in WhatsApp and iMessage
    2. Reliability: It is not a big red flag but I’ve had the app freeze and shut down a few times. Again this happens very rarely and is not something to worry about.
