    Worker friendly program with a selection of interesting features

    Date: Nov 27 2020
    Summary

    He appreciates the employee's individual hours of operation according to the individual's time zone, as well as automatically postpone warnings at a later time, which is flexible. You can settle down on your own, on a trip or on a holiday, use any type of custom icons and gifs, and participate in fast, relaxed business discussions.

    Positive

    The alternative of having multiple work areas, mute, snooze, personalized emojis, networks, team messages, personal privacy control, combination with apps like google drive, assistance in marking the location of the message, fixing messages, individual area for notes, responses, safe as draft, web data browser, as well as external APIs with the ability to make use of flexible user interface to publish daily automatic information updates, makes it really effective and very easy to use.

    Negative

    The minimum storage space in the variation makes me lose my old messages and also data, which is also much less a room for an entire office that they are using, we are moving in the direction of where the information storage space is preferably not such an issue good as this, except an individual who uses it individually. In fact, I have kept essentials that can be recovered only based on the company that acquires a strategy and I have no control over it independently.

    Great software for collaboration

    Updated: Oct 28 2020
    Summary

    I simply love it, have been using it since 2016, and seldom have I opted for another, surely there is always room for improvements. I have much respect for the creators.

    Positive

    Let me start with this, the list of apps available for integration is huge. So is ability to manage multiple tasks in a small org or a class project. I absolutely love it. Simple UI, not much clutter. Doesn't freezes compared to other similar software when I start it.

    Negative

    Use of hashtags do confuse me, they could've used bullet point symbols, video conference is a little glitchy sometimes.

    The best method for multi-project communication

    Date: Dec 22 2020
    Summary

    When using Slack, I certainly recommend having some work environment policies and also support to ensure that it is used in the most efficient way. The daily work procedures are structured according to our usage clearance today. In addition, it is an excellent system to use based on the ability to use emojis and GIFs that help us build relationships with customers.

    Positive

    Slack's user interface is nice, simple to use and is an incredibly integrative definition that can put in a lot of effort / assuming established alerts for when my conferences are about to start and when people talk about my records.

    Negative

    The variety of channels and workspaces in Slack can be unrestricted at times. The variety of messages and workspaces to move around in the same way can be quite tiring. It would certainly be fantastic if there was a less complicated method for acknowledging alerts from each office in a main area to prevent the loss of warnings occasionally.

    Best For Communication

    Date: Dec 01 2020
    Summary

    Channels can be public, private, common or multi-workspace. You can study the distinction in these channels here.
    It makes it simple to share and work together with somebody continuously. This is extraordinary for when you need a prompt reaction about a cutoff time.

    Positive

    You can make "channels" inside the organization. For instance, you can have Slack channels for every customer that incorporates all the associates who are engaged with that customer venture.

    Negative

    Your discussions get erased following 14 days, so in the event that you are sent something significant inside a channel, ensure you make a note of it.

    Positive

    The application looks professional and best for large and medium size business. It provides good number of features to manage remote team. The documents and other media files can be easily shared with team members.

    Very User Friendly

    Date: Jun 19 2020
    Summary

    I would recommend Slack to anyone looking at using an internal communication tool. It was particularly useful during quarantine time.

    Positive

    We rolled out Slack a while ago and I was resistant at first, but as I began to use it, I realized how useful it was. It is very easy to use and I like the ability to call through Slack.

    Negative

    I thought the use of too many channels made it difficult to keep track of all the different posts happening.

    The Gold Standard in Professional Messaging

    Date: Nov 25 2020
    Summary

    Slack is a powerful, reliable, flexible messaging program that has a wide range of additional features. Their app marketplace features tons of integrations with other business software that can streamline your collaboration even more. I'm a little concerned with feature bloat and how resource-hungry it can get, but it's still the best messaging software available today.

    Positive

    Slack has wide adoption across various industries with good reason. The interface is intuitive, it has flexible features, and offers tons of integrations with other software you're probably already using. I use it for collaborating with my colleagues, sending messages, exchanging files, and occasionally using the VOIP functionality. Integrations with our office suite make all of this work very efficient. I've used other messaging services and Slack just offers more features out of the box.

    Negative

    Slack is updated frequently, which can be good for regular bug fixes and updates. However, this also means that the interface changes in big ways regularly. Even if you're used to the fast development cycles of online software, you may still feel inconvenienced when your favorite feature has been moved, or you have to re-learn how to use a common function. Also, the additional functionality has made Slack resource-intensive compared to other messaging apps.

    My opinion on Slack

    Updated: Apr 08 2020
    Summary

    For experienced users, it is a good platform. Only the new users would face the problem of understanding it.

    Positive

    A good platform for instant messaging only if you are a lot familiar with the platform. Works on different platforms.
    Topics or discussions can be created using threads. Each thread can hold a different topic.

    Negative

    It's quite messy. For a beginner, Slack appears to be chaos. I had even missed an online course deadline for the first time I joined slack.

    Positive

    Slack is super easy to set up for a team. We use it with a team of 25 and it's super convenient for us to be able to collaborate all in one area and in channels.

    Negative

    There is a small learning curve when you start using it but you can adapt to it pretty easily if you use it consistently.
