PERFECT BRIDGE BETWEEN AGENCY AND WORKERS
Slack qualifies to be the best collaboration tool of our generation with users navigating the app with quite a lot of ease. The experience at large is very positive and with such competitive prices, indeed there lies infinite potential with slack. It offers several intergrations iclusive of outlook and zoom among other essential plugins.
PROSAs a messenger app, the basic functions enabling communications are on a perfect edge with a simple, precise interface very easy to navigate. The search option comes in as a plus as you are able to trace your target messaage on a long thread with simple typing of words on the search bar. With slack, we are able to share files with quite a lot of ease and now with the IRC style, we can separate the conversation threads in the presence of multiple members in a team to set up off-topic discussions.
CONSWhen sharing your screen with another team or individual, you have to go back to the initial chat to send a message, I would prefer this being done from the same UI of the screen-share. Also the limitation to the number of users attending a video conference does not confer with large organisations such as ours.
Reasons for switching to Slack
Inavailability of notification alerts for meetings made it unreliable.

Usage Review
Using Slack has been smooth when it comes to communication in our company with team members both in remote and office environment. It's easy to integrate with other apps where it's able to make work easier in both file sharing, presentation and video calls.
PROSUsing slack is easy and fast to learn Able to share large files Easy to use for presentation
CONSWhen adding people in a call it can limit group call numbers

Slack is essentially advanced texting for business users
I started using Slack because my client required it. I find that it cuts down on my email dependence but I'm often frustrated when attempting to compose a message without standard elements such as tables, inline images, etcetrera.
PROSI like the ability to stay in touch with our users via whatever device I'm currently using. For example, I can respond from my home computer, tablet, work computer or via my phone. I especially like the ability to be notified of a new message via my phone where I can read the message on the phone but can step over to my laptop to reply. I also appreciate the ability to add an email thread to a Slack Channel by simply adding a slack email address (each channel has a unique email address) to the CC field when I reply.
CONSThe biggest con for me is the extremely limited amount of formatting available to Slack messages. I can make a font bold and add links to files/images but I really miss the rich text features many similar apps provide. It's also frustrating to need to keep typing adding the user name(s) when I'm responding to a message. I'm assuming that this is by design but it would really be nice to be able to "Reply All" to a conversation thread. The desktop Slack application (running on Windows 10 Pro) has a "clunky" feel to it. It's written with a framework that allows the Slack developers to write HTML and JavaScript code that is essentially compiled into a Windows application and it definitely shows. Something as simple as selecting text is counter-intuitive (until you realize that it's essentially a web page mascaraing as a Windows application.

The Fastest Way to Communicate with Your Team
We have team members in different time zones, who don't always have their email pulled up. Slack is the best way to get in touch with any of my team members who aren't in the same office as me and get questions answered fast without cluttering up my email.
CONSI wish there was a faster/easier way to temporarily mute or unmute notifications at will. Sometimes I hop into a virtual meeting and I have to completely close the slack application to be confident that the slack notifications won't make noise in meetings.

Ended internal email overload in one day!
Making progress on internal discussions can start in seconds with a Slack group chat. It is hard to imagine a way of managing teams in different countries any other way. Slack removed a reliance on internal emails which often fell short where key people weren't copied in or involved in the discussion. In a similar way, it avoids the CC happy emails where some team members may not need to be included and is an unnecessary distraction. With public channels, anyone can decide if they continue to remain invovled or just choose to 'mute' a channel, even just for a period of time. After using it for over 2 years now, the results are that people in our organisation can manage their communication and let it fit in their workflow. With various integrations it can also be a real timesaver when on the move.
PROSThe options of private/direct group conversations and public and private channels make the various types of cross-team communication most companies need so simple that it's hard to remember how we got anywhere when relying on email. As a personal favourite feature, the option to upload custom emojis makes messaging easier, not just for fun but in the cases where logos/symbols can be easily understood by everyone, it makes quick shorthand.
CONSSomeone who reccomended this product did warn to be careful that it may take over our lives, and they weren't wrong! Through no fault of Slack , the ease of adding channels, setting up groups etc does admittedly add to the noise that can sometimes be a distraction. The Slack call quality can sometimes be unreliable and audio quality isn't amazing.
Reason for choosing Slack
We barely tried alternatives as Slack was so highly reccomended, by the time we begun evaluating it , it was already sold. If there were other software used for 'Chat' they will all have been removed.

It's changed the way we communicate!
As I said, it's changed the way we communicate. This is especially important for our company that's not only split between two main offices in different locations but now also has remote employees across four additional states. Slack helps us stay connected to the teammates we rarely see in person, allowing us to build friendships and maintain an awesome company culture. It also helps our entire team stay informed on everything that's happening within the company, from customer service to development.
PROSBefore Slack, our team primarily communicated through email and one-on-one chat services. This caused a lot of miscommunication and wasted time going back and forth between people, passing on information, etc. Using Slack took away all of that. Being able to chat through channels allows us to communicate with groups of people at one time so everyone has access to discussions that might apply to them. We also really value the video chat feature because we have several remote employees that you can talk to face to face with a click of a button. Which is far better than having to go open some separate video chat app just to make a phone call.
CONSSlack can be a little "noisy" for some people, but there are ways around that, so I don't really consider it a bad thing. It's just up to each user to figure out how to make Slack work best for them. We've had some complaints within our team about the new text formatting, most specifically our engineers that preferred doing it on their own and find the new user-friendly format to actually be a hindrance. They'd really like for that to be a feature that each user to choose to enable or not.
Reasons for switching to Slack
Google Hangouts, at the time that we were using it, was very limiting and inefficient. Communication was often lost or time was wasted with multiple, similar conversations happening between different people.

Great integrations with tools
We were on Skype for Business and the features on Slack are much richer and better. Some people are using Teams, which is also a good alternative, but for some people the heavy footprint of the full Teams product was a bit too much.
PROSIt's an easy, reliable tool to use for messaging, and easily organizes teams with channels for discussion. The integrations with web hooks are also very useful for using other developer/production tools for software development. Custom slackmojis are also a fun morale booster.
CONSThe free version has a short history span, but this is understandable given it has a free version. When having a direct ad hoc conversation with multiple people (not wanting to setup a channel), it can be difficult to read the names for each conversation and distinguish one from the other. Maybe there's a way to rename the convo, but I haven't found it yet.
Reason for choosing Slack
Lighter weight, and we have some company developers who only use Linux so because there isn't a Teams for linux distribution we couldn't use it.

The right tool for the job!
Best thing that happened to our company. Our productivity has increased since and our "reachability" as well. We feel very close now, even for our team which is 100% remote.
PROSThey really put the work into making a chat software that is very usable. intuitive, agile and overall, very enjoyable. We use many of the bots the marketplace has, especially the Google Calendar, Zoom, Giphy and Slackbot integrations that comes with it.
CONSI cannot think of much of what I dislike about Slack, because I like everything about it. I used to have an issue that Slack didn't load properly, but an update and empty cache button swiftly solved it. Sometimes the calls ring on the phone first before doing it in the computer.
Reason for choosing Slack

Reasons for switching to Slack
We used to have Skype (not the Business one) for our internal communications and since the switch to Skype 8, the experience became really really bad for us. Some of our users do not have good computers and Skype 8 became a really heavy web app. For smartphones it became really painful.

Slack review for company use
Overall It's a very useful app for little teams and big companies, you can manage your team/s with this app, beside chatting and conversation, it seems like you can visualise your work here with many addons. For example I have integrated github, jira, pivotal and these types of apps and can see notifications coming from this task managment tools in channel, like everything one place, event can call inside channel with hangouts app.
PROSI like team workspace like design of app, especially the channels for teams, private channels, taggings by team, threads, and bots inside it which are very useful for variety of reasons, helping to increase users productivity and contributing for team to work fast. Another thing seems to me very useful is integrating google calendar with slack which show to my teammates when I am busy or in a meeting or when I am free near my name on app.
CONSSometimes it has problems with mobile app push notifications, e.x many times I tried to reply message from push notifications but seems it not sends message showing could not send without notifying me. Another thing I noticed in recent times It has problems with video streaming, I mean when someone uploads video It sometimes streams very slowly .

Best Team Communication Software Out There
Very positive. Few complaints. A super fun, dynamic, effective platform for work, projects, etc. alike.
PROSI don't think anything can compete with Slack. It's quick, efficient, fun to use, social, playful (GIF's! /giphy), unclogged and dynamic. The calling and group chat features have been especially handy lately with remote working. I also love that you can add such a diverse range of content (code, movies, images, gifs, lists, quizzes, link previews, etc.). The polls + GIF randomizers also keeps things 'fun' and light, useful for all types of people in all types of roles. The UX is very straightforward, the interface design is beautiful and FUN, which is important for a communication platform. People enjoy being on Slack. I don't mind opening it up - and that means a lot, considering it means I'm working. The search and archive functions are also great.
CONSDon't have many complaints, honestly. I think it might be better if you had a way of storing 'updates' for projects, the way Basecamp does. Pinning messages, or files? To prioritize them, so they don't get lost in the conversation flow. Also could maybe benefit from a 'presentation mode' for Slack video, unless it exists already, to compete more with its competitors like Zoom? But overall, I have few/no complaints.
Reasons for switching to Slack
More applicable for cross agency/departmental communication. Less technical, more human.

Why We Use Slack For Our Start-Up
Slack has been a great addition to our daily work ethic. Being able to use it on a mobile device as well as desktop is key and it has become an integral part of splitting up our tasks. I really couldn't recommend it more.
PROSThe overall ease of this software is superb. Every one of our team members found it easy to use immediately.
CONSThe one thing that bugs me is the return button. If you are writing a message then if I want to use a new line by pressing return Slack actually sends the message. So I then have to go in and edit my message. Return in Slack is another key. You would think would be easy to remember but then every other product has the return key used as a new line so I'm always having to edit my messages of they are spaced out.
Reason for choosing Slack
Slack offers a free version so that was great at the beginning. Once we started to use it it really was the software we were looking for to chat about specific projects. We work all over the world and in different time zones so this was the best fit for our start-up company.
Reasons for switching to Slack
Asana just didn't have an easy user experience compared to Slack. We wanted to chat more about our creative projects and Slack filled that area better than Asana.

The best remote collaboration tool I have EVER used!
Slack is the easiest collaboration tool I've ever used. I am currently acting as Scrum Master for four agile teams, and it's easy to keep in touch with all of them and coordinate standups. File sharing is extremely easy
PROSSlack is a user-friendly, robust collaboration tool that allows for quick setup and access to channels both public and private. Asynchronous communication is a cinch and the Mentions and Reactions feature allows for easy access to what recent messages you have received.
CONSDue to Slacks' third party app space, there are some features that might seem to be missing at first but need to be found as a third party feature. This involves an admin or an owner having to approve the app being installed. This can sometimes be a bit of a headache on the admin end, as it requires going to obscure parts of the app to approve. It could be an easier experience.
Reason for choosing Slack
Teams lacked a lot of the features Slack has, such as custom reactions, quick calls and file uploading. We decided to stick with Slack as it offered what a more agile-friendly experience.
Reasons for switching to Slack

Community Management for Non-Profit organizing
Setting up Slack was quite easy once we received a non-profit grant for the standard license. Some people had to be taught in detail but the transition was overall fluid and is now universally considered a smart move.
PROSSlack enables structured communication within and across working groups (protest planning, tech, outreach, lobbying, etc.). Having access to all relevant streams of communication in one place (that isn't the personal messenging app) is crucial to maintain any semblance of structure.
CONSIt took some time to figure out proper ways to handle our most common workflows with or without bots and integrations (eg. voting, scheduling). Integration with our knowledge base app, Nuclino, remains barely functioning.

Slack as a virtual Workspace
Overall it is excellent tool for communication. I did not explore more complicated features yes, but so far, on the basic level, the functionalities are flawless, and, most importantly, it is easy to deply, easy to learn. Some of my employee are not technologically savy, dont like learning new apps of softwares, but Slack was implemented practically without problems. I tried the pro version, but for my needs it did not differ from the basic plan.
PROSI moved all my communication, file sharing, project managing, discussions inside my organisation to Slack. It was motivated by the price, accessibility, ease of deployment, and great, impactfull features like threads in communications and bookmarks for file sharing. Real time synchornization also played a big part of my decision. I check about 10-12 different software before deciding on Slack and it was one of the best decision for my workflow.
CONSSome of my employee complains about temporally losing access to Slack, but I personally never experienced something like that. Nevertheless it can be frustrating, when all my communication is done by Slack and some employee can't log in.
Reason for choosing Slack
I needed something that will be easy to learn for my employees. I have frequent rotation of employees and i dont have time to teach new employees a software. For me software must be self-understood, intuitive. And Slack is exactly that. I consider this its biggest advantage - after installing Slack all my employees intuitively know what to do, what to click. Price also played a role, but not first and foremost.
Reasons for switching to Slack
Firstly, price. Secondly i had a lot of problems with Teams - with functionality, acess, deployment, implementation, integration. Searching through conversation in teams was painfull, and file sharing was a disaster.

Communication for (Cool) Professionals
We can definitely communicate with almost no exceptions. It takes the "where is this person" out of the equation as you can just send them a message and know when they come online and see it. The benefits to not just sitting and waiting on an answered email are endless.
PROSI don't remember how my team communicated before Slack. It keeps my coworkers connected in and out of the office. It cuts down on our emails and makes communication easy. There are a lot of apps and integrations that can be added to automate processes. You can integrate project management tools, Google Docs, Spotify, Canto DAM, Giphy for some fun with coworkers and so many more. I love that I can drag and drop files, images and videos into slack to share with my coworkers. In addition, slack allows free integration with many other tools out there. My peers who are software developers talk about how easy it is in the backend for integration. Slack is easy to use and has great built in functions for notifications. It has really been extremely helpful to get multiple departments talking at times and keep each department informed while not in the same location. The ability to upload files makes it easy to share ideas.
CONSThe Screen sharing could be improved, along with mic recognizing. When network connectivity is lost during screen sharing or calls, the reconnect feature doesn't seem to work really efficiently. My biggest complaint is that Slack makes you way too available. You're expected to know whats going on whether you are at home sick or in the office working. Sometimes the app on the phone won't clear your notifications even after reading or checking through them.

The Ultimate Tool for More Slack Time
Our company (software delivery solutions company – software industry) has been utilizing Slack for over three years to help both our internal and external teams keep organized. Our team often holds meeting remotely and works with distributed teams, sometimes even in other countries. Having the ability to communicate in one place has shown visible improvements in time and efficiency of getting our team work completed. Slack allows you to set up multiple “workplaces”. For example, we have one workplace we use for our external team and a secondary workplace for our primary, internal team. This helps us keep the responsibilities we share in each team separate of each other. Within each workspace you can create separate channels based on a particular group or topic and invite specific members who pertain to it. You also have a channel that enables everyone in that workspace to communicate within one area and/or you chat directly with one individual from that workspace (which would not be visible to anyone else). Slack’s search features are very helpful and work much like Google. You can also specify your search’s by choosing an individual, date, or key phrase to search for. Uploading and sharing PDFs, Excel, PPTs, etc. is also supported and can be easily shared among others. We rely heavily on Google as our file storage system. The free version of Slack provides you with the option to connect it to your Google Drive account so you are notified, with a link, when anyone share
CONSBecause we are currently utilizing the free plan for a fairly small to mid-sized team we often run into storage problems. When this happens, the only option you have available is to have each team member go in and delete EACH file individually. This is very tedious and time consuming and can take hours to delete 500 files (tip: keep up with it or do searches to make sure you don’t upload the same files that have already been uploaded to Slack). You can also clear more storage by having the admin delete messages from your teams’ shared messaging area, or what we recognize as our case, “general” channel. Having the ability to look back into your history is very handy. I would strongly recommend the Standard Slack plan for those who have the extra wiggle room in their budget – which provides unlimited search history and app integration. I currently utilize the desktop application of Slack, so that it is always on my tool bar and easy to access on the daily; however, it prone to timing out when losing internet connection.

This is the new way to communicate online
I use Slack for daily communication business and to stay connected to coworkers and suppliers distributed among different locations. We have implemented Slack as a missing link that smoothly makes working with people on the other side of the country as if they would be sitting in an office just down the hallway.
PROSSlack is simple, it is easy to use it has a lightweight user experience thus, at the same time is very powerful. In day to day routines it is just a great way of communicating (chatting) with coworkers. Perfect, reliable, fast asynchronous communication. Then someone tells you something you need to remember next week- use integrated reminders, that send you a message when you need it. Or you want to share your desktop real quick, to sho someone something in order to get their opinion. Slack has you covered. Or have a video call with someone or even a group of people. There you have it. Share files ? No problem. Want to have your conversations deleted after a while. there you go. The most impressive thing about all this is the simplicity and ease in which these features integrate into the core functionality which is a chat. Bravo !
CONSSome of the features seem - behind the scenes - not optimized allready. Sharing data from my mobile device require it for example, to be uploaded first and then downloaded to the recipient. It works, but it takes more time and, I don't care when it is on the server I only care for it to reach the intended recipient(s). Synchronize it to the server whenever its suitable. Connection and reconnection gets tangled up sometimes, with Slack insisting that there is no connection available although all other applications have reconnected already. This however is complaining on a very high level, as these issues are really minor compared to almost all other platforms for online communication I have used.
