About Slack
Slack is your productivity platform. Welcome to the command center of your workday.
And I have really enjoyed the community-centred interests people put into ensuring your challenges are taken care of is really encouraging. I love Slack for this singular effort.
The only drawback is that we just have too many avenues where we connect and so Slack just got lost with all the other programs and didn't become a priority. This is why we no longer use it.

Highly effective and secure tool for team collaboration
Comments: Overall, Slack was an outstanding tool for collaboration among our team.We were confident in data security knowing that all data, both at rest, and in transit, is fully encrypted.Data security is increasingly important for all firms, and branches of government.
Pros:
During branch meetings and discussions, dozens of us were able to discuss a range of topics in real time.Also, Slack is one of the most famous collaboration tools (text, voice, video and file exchange) that runs on nearly all platforms: Windows, Mac, Android, Linux, iOS, and in an online web-based version. Brilliant!
Cons:
Occasionally, Slack would not load properly and experienced connectivity problems with video and audio. But these problems may have been a result of our overloaded server, and not a problem with Slack. The allotted storage space for users may not be enough if you have large files.
Great Platform for Internal Communication
Comments: Slack is a convenient workplace communication tool. It allows us to create different team channels where we share the details of a specific project. Slack sends real-time notifications to ensure no one misses important information. We usually use it for business communications and use other apps for personal chats and it meets our expectations.
Pros:
Slack is a versatile platform that allow convenient communication using text, audio, or video. It has an simple design which makes it easy for anyone to get started easily. Slack sends notifications quickly, ensuring you don't miss important files or communication. It is better for official communication than the regular apps we use on phones daily.
Cons:
I dislike too many emails notifying me what happened on Slack. The notifications may come in handy when you missed a lot but they could also bother you because they are rather too many. The mobile app seems too congested compared to the desktop access version.
The almight community platform.
Pros:
Slack as a community app allows me to connect with others who have similar interests, share information, and support each other.
Cons:
Nothing really, slack fits all I use it for without an exception.
Alternatives Considered:
Essential but requires some effort
Comments: Initially difficult but once the balls get rolling it is my favorite app to get in touch with my communities.Much better than the social media app like Facebook or TwitterThis is the true meaning of community!!!
Pros:
Very nice way to handle the thread Possible to upload files and images easilyThe multiple channels is amazing to separate groupes and discussionsThe mobile app is amazingI love the notification system
Cons:
It takes some effort to understand the mechanic of itA bit difficult to invite people form outside the companyMost people do not respect the Thread replies and that makes it difficult to follow some discussionsA bit difficult to find specific posts
Alternatives Considered:
Standard chat app in IT companies
Pros:
In our company most of internal communication and support of key customers go through Slack. Slack Connect is a really great thing, especially because Slack reached network effect.
Cons:
Lack of autocompletion using AI and advanced spell checking in messages.
Alternatives Considered:
Great tool for communicating with a remote team
Comments: It's become a fairly ciritcal tool in staying efficient and communicating
Pros:
Slack makes it easy to communicate with my team and share files in real-time with my offshore team
Cons:
I find it a bit hard to navigate at times and I probably don't use all of the functions to capacity. It can be confusing
Work From Home Using Slack
Pros:
Slack is one of the best in my opinion, the features and integration are just great!
Cons:
One thing that annoys me is when you deal with preferences in Slack. The setting isn't saved so every time I open Slack on a different platform, I have to set the preferences again and again.
Best of breed collaboration tool & internal knowledge base.
Comments: Highly recommend no matter the size of your company.
Pros:
Easy of use with virtually no training requiredGreat UIReliable/stable
Cons:
Can become a bit noise with notifications as your channels grow.Easy to lose threads when channels get busy.
Increase the efficiency of work groups and projects with a unified communication platform.
Comments: Time saver. Straight-line communication organized in a single location.
Pros:
It's simple to use and requires no change to current processes. So much better than Email threads. It adapts to any project/use-case/team size.
Cons:
It would be good to be notified of those who haven't read messages or checked-in to a group conversation. "Compliance" Management.
Best one for sharing files and private informations, fantastic Product..!
Comments: During my experience in communicating with the parties at work, it was a good experience in using and communicating with keeping internal information and others.
Pros:
Really smart program to use as it facilitates the dissemination of information and internal development of work.
Cons:
Good and accurate program in action. it's best one

Slack's As Good As The Team That Uses It
Comments: Slack's an incredibly important part of our organization's tools now. At first there was resistance from some in leadership: would it be distracting, would it be yet one more thing that confuses people about where information is and how to find what you're looking for? But we set some ground rules and best practices early on and had a small team try it out for a few months before making it available company wide. Establishing the expectations around slack and making sure that everyone understands that it's not a tool that people should be expected to be on all the time is critical.
Pros:
Slack has been great for our company. Yes, it does cut down on the number of emails our team sends, and it has enabled us to work with our remote colleagues more efficiently. The desktop apps and mobile apps are well designed and the improvement to UX that comes with most updates is often welcome (e.g., recent addition of the Drafts feature).
Cons:
The things I like least about Slack are not issues to do with Slack but instead to do with implementation, rules, culture, etc., etc. Like anything that's good and revolutionary, the implementation of Slack requires an understanding that with benefits come downsides. Be wary that humans using this software will remain humans and their idiosyncrasies and personalities will not be masked by the communication tool.
Alternatives Considered:
Staying on the same page is important
Comments: Slack really helps my employees stay on the same page but only if they use it. Sometimes I need to remind them to use it. It definitely helps keep people informed of current events at the company.
Pros:
What I like most is that slack is incredibly customizable. If you can think of a thing that needs to be done in the workplace slack has an implementation of it. Keeps everyone on the same page
Cons:
Notifications can get out of control without setting up when you want to be notified. If you sign up for the free plan it doesn't save your conversations for more than a few months so you'll need to send any critical important data through email.
Functional Office Communication
Comments: There is still so much to learn with this program, as we have only been using it for less than six months. But so far, we love it! It's fun, creative, a time saver, and very well liked here in the office.
Pros:
This software allows you to instant message across the office in a simple, easy to use program. It allows you to create as many "channels" or groups as you need, as well as chat to individuals directly. We use this form of communication to ensure our messages are documented and our team is help responsible for the communication received. The feature my team enjoy the most is the ability to branch off into "threads" off a single topic so it doesn't get lost in the chat, and the ability to add a reaction, giphy, or insert a picture in a way to have fun with it as well! I particular like the use of sending myself "reminders" directly off a task, chat, or thread that I can schedule to remind me whenever I need it. Speaking of schedules, this program also links to our schedule so whenever something is added, we automatically get the alert.
Cons:
The only suggestion I would recommend is to incorporate an auto response or notification that a message has been read. This would aid in the accountability and to ensure a message didn't get lost in the chat.
The unbeaten king of communication tools.
Comments: I doubt I could ever use something that isn't Slack, probably due to the fact there is just nothing that even comes close to its balance of features and fun. Which is kind of sad as its clear Slack stopped innovating as soon as it noticed it pretty much had a monopoly on workplace communications.
Pros:
Slack biggest achievement and PRO is making workplace chat fun, be it by fun emojis, gifs or reaction emojis to messages, or its sheer amount of customization options. Add to this the insane amount of project customization thanks to 3rd party integrations, and its clear why it's as of now still unbeaten. Also, the fact it has plenty of developer centric features such as syntax highlighting and impressive platform compatibility across OS just makes it even harder to compete against.
Cons:
Slack's biggest problems are 2, performance, and price. Even on relatively powerful hardware, Slack is prone to having performance issues, probably due to the fact its built with web technologies which are great for compatibility reasons, not so much for performance. Also, their pricing model makes it pretty much impossible for small companies and groups to buy due to how expensive it is.
Pretty great way to connect with your team
Comments: I really enjoy using Slack to connect with various groups and individuals I need to interact with both inside and outside of my work organization. Adding additional connections outside of my organization is easy and then gives me access to all work-related communications inside the app I already use for work communications. Very convenient!
Pros:
It's easy to set up new workspaces, and once they're set up you have an easy way to connect with all the people you work with simply and in either a synchronous or asynchronous way. This is especially helpful when connecting with people from multiple timezones.
Cons:
Video calls are pretty resource-intensive so it's sometimes hard to do such things as share your screen to demonstrate a problem you're working on. Furthermore, those controls always get in the way of what you're trying to do. It would be nice if they could be minimized into a floating button, or something, that you could move out of the way until you needed them.

Slack is the best for fast conversation with the perfect sound quality.
Comments: The audio and video calls quality is always perfect and awesome. It always provide the great options to share screen and important information, data and documents in a instant manner. Overall, Slack is the most intuitive and perfect for business meeting. Hence, this software provide the best video calling with the perfect sound quality. The another thing that I most like about this software is that we can easily chat with the audio and video calls in a more efficient way. This software is the best source of communication because here are chatting opportunity is always free and reliable. Through the Slack software, it is so easy to connect myself to anyone and at anytime in the world.
Pros:
Slack software is very easy to use and cloud sharing is too amazing of this software. Slack software is great for the audio and the video calls. The most favorite thing about this software is that it has the superb features with the great ability. I can also share the important information with anyone in a more efficient way. The another benefit thing about this software that provide us is that it is the best for the fast conversation with our friends and colleagues. I would recommended this software because Slack software is highly productive with the lots of good tool and features. For us, it is the best communication and the great video calling software. It really helps me in a ll of my business meetings. Moreover, it always provide the great customer services for its users. We can always handle all of our conversation in a group video chat in a best manner.
Cons:
The great disadvantage of this software is that sometimes with any internet connection, it makes our communication so difficult and harder. Moreover, there are some features that are missing in the Slack software. So it should must enhanced the quality of its features. The another problem that we faced is that sometimes we cannot fast conversation in a group video chat, because of some internet problems. For the new users, it is so difficult of us to use it more properly. Otherwise, it provide the great conversation for the audio and the video calls.
Excellent Team Communication Program
Comments: Being in Marketing, my team and I have to send many large design files on a daily basis. During a review process of one project, we may send up to 20 files back and forth. We found that sending via email was clogging up our limited email space very quickly and it also became difficult to go through an email thread to make sure you have all the notes from different team members. So, we began searching for a communication platform that would not only allow us to send large files, but one that could also make communication easier. We have found that with Slack! We started using Slack just over five years ago and we never looked back! The file-sharing capabilities are phenomenal. Whether you are using the desktop app, online version or mobile app, files and attachments are easily downloaded or you can view them directly in Slack. With many of our team members working remotely, Slack has also made communication and collaboration on projects much easier. By creating different channels, we have been able to single in on specific projects. That way, communication is not lost in a long email thread. Furthermore, the search capabilities within Slack make it simple to go back in a conversation and find any past content. Slack also allows us to one-off each other, when we need a more private conversation or a direct comment needs to be made. We are also enjoying the notification and status settings. All of us on our Marketing team would highly recommend using Slack!
Pros:
Hands down, the best feature about Slack is its file-sharing capabilities. It has made our jobs easier as a Marketing team to have this in a communication platform, especially since we need to send many files on a day-to-day basis. With many of us working from home or out of the office, having a centralized communication platform where we can communicate on projects, while file-sharing, is essential. It has kept us all out of "email jail" and has streamlined our review processes and turnaround times for meeting crucial deadlines.
Cons:
There is very little I dislike about Slack, but I would say that the "Threads" communication portion of Slack could be developed a bit better. With this feature, someone can reply directly to a specific comment rather than in the full channel. The only issue with this is that the thread pops up on the right side of the screen, rather than directly below the original comment. Sometimes, this can be confusing and the notifications for Threads can sometimes be overlooked. If Slack were able to open the Thread directly under the original comment/post, that would make communication and notifications less confusing.

An efficient and reliable inter-office communication tool!
Comments: Slack has been instrumental in connecting everybody in our organization. I'm not just saying that. Various departments within our company have become competitive and often complete projects way before deadlines. That's because we've applied and integrated Slack into our organization in such a way that we use internal performance appraisals, awards, etc to achieve this. Also, we are a SaaS company that believes in a positive work atmosphere and Slack helps us achieve just that.
Pros:
1) User Interface: Slack is quite user-friendly but requires a little bit of an initial learning curve in order to get that hang of things (considering it's a bit different from your average personal communication tools). In no time, you'll be able to locate new channels, switch between them and message individuals directly. 2) Making Work Fun: As its name suggests, "Slack" allows users to ease professional tension and stress by providing them with a wide range of "Fun Gifs", emojis, etc. Users can even make use of different "reactions" (Just like you have on most Social Media Platforms). This is quite useful for us because we can vote on posts using various reactions. Our in-house designers often compete with each other on various projects and the rest of us vote for them. Therefore; Slack = Increased Productivity. Of course, you can have your own methods of applying this feature. 3) Suitability: Slack is best suited for small or medium sized businesses. They have a "free forever" plan, a "Standard" plan and a "Plus" plan. The main differences between these subscription models are chat-log backup capacities, the number of third-party app integrations you can use (Unlimited for all paid plans), Customer Service response timings, file storage per user and few other differences. 4) Notifications: Slack makes it possible for its users to have many options of getting notified. The best feature, in my opinion, is where someone can "@" you in a message or a post.
Cons:
1) File Preview: It would be nice if you can preview a document without having to download it first.

Essential for Running any Tech Business in 2019
Comments: Overall, Slack has been able to bring our teams together on both large scale and smaller scale business services where there are no longer dependencies in communication because all the important information is either sent as a message on each channel or sent as a reference link on each channel.
Pros:
I currently run two separate companies, a tech repair company and a digital marketing firm, both of which rely heavily on large-scale business services. Slack allows both companies to efficiently manage each project with the channel functionality, where each of our projects is placed into a separate channel where we discuss important updates, share important documents and Tag important notes. All of this is made incredibly simple with slacks dead simple user interface and it's most certainly safe to say that our companies would face difficult times without this software.
Cons:
There is one small annoyance that I have had with the software ever since our companies began using it years ago: the naming scheme for each slack channel. Each channel requires you to have lowercase letters with no spaces allowed and instead only allows underscores. This obviously in not an important issue, but it has definitely annoyed me in the past when I had to retype some of my channel names.
Slack Public Channels improves company communication across teams.
Comments:
It's a great tool, these are the key points for me:
* Improve team collaboration, shared information in a single place and all team has access to the same information.
* Reach people, sometimes you need to collaborate to make things happen, and slack does a great job at that.
* Integrate to CI/CD pipelines, we received notification about or system all time. It's better than having thousands of emails.
Pros:
Public channels: They are easy to create/configure and allow members of the company to share important information in a single place. This is really helpful for software development teams when important information is shared with other application it gets lost and there is no record of it. With the slack channel, the information is stored and can be used as references. (Developers don't have or we don't want to have time to write documentation). 1:1 Message: What I really like is that is very easy to find people and ping them and start a conversion. Most important, you can share files, photos, URL, gifs (Very important), in a single place. Making collaboration easy and something to enjoy. Integration: Slack can be integrated with a lot of third parties. In my case, it's very useful to integrate with Jenkins and code versioning applications. We have implemented CI/CD and we received a slack notification with deploy information, testing information or if a system is down. Cross-Platform: Be able to access slack with cell-phone/desktop application is really awesome. If I don't have my computer at hand, I can keep replying messages and collaborate. Especially important when we have a critical bug, or we have to take action. UX: The UX is one of the best, you can start using slack with no training, it's very intuitive and easy to use. Once you start using it, you don't want to use other applications.
Cons:
Conversion history: Sometimes the conversion history is deleted after N amount of dates. Probably this is a configuration in my company, but I would like to store more information. Re-Login: Once in a while, you have to re-login, but what I don't like is that it logs you out without giving you a warning. It had happend before that the application logs me out, and I notice that one hour later.

We are SLACKERS
Comments: It helped my company reduce the spillage of work into everyone's personal social media. It's also a really great way to communicate with coworkers and get things done. We've almost eliminated internal emails!
Pros:
The company I work for used to use a group chat in a social media platform to try to communicate with our employees - we're small, and the number of employees wasn't too large for this, but we had quite a few different group chats, and they all bled into our personal lives. When I found #Slack, I immediately knew this was the answer to the ever-leeching work-life balance conundrum caused by having everyone at work affiliated in my social media account. Within a few weeks, we had our core chat channels set up in #Slack, and we even installed busybot and a couple other add-ins. We were customizing it and using it company-wide in no time at all. It's been a life saver. The channels keep different streams of communication open, and the best part is that it's FREE - as long as we don't want to search back through past 10,000 messages in our archive, that is. But the best part of THAT is that it's there to upgrade when we want to. I actually have two jobs, and both of the companies I work for use #Slack - it's just that much better than the other options out there. We integrate our Google Calendars with it, and they show up in the channels we've chosen to filter them into so that employees can see the schedule for the next day.
Cons:
The only thing that I feel is missing is the ability to copy an image and paste it directly into #Slack from the desktop. You have to download the file and then upload it, which is not a major problem, but most applications have this ability now, so I constantly try to do it, and then it doesn't work.
Slack for Team Communication
Comments: We use Slack as an internal team communicate tool for transparency of discussions with team members in multiple time zones and also to encourage team bonding. Direct messaging is also conveniently located here and since most of the devs on my team don't actual bother to login to the company mandated direct messaging team, it's easier to get ahold of them.
Pros:
My previous experience with group real-time communication was IRC. As an employee who had just barely gotten their toes wet using terminal, IRC was intimidating to run and intimidating to find any past conversations because searching it required terminal commands and a third party plugin to just login. It also did not retain history when you signed off, so as one who is on a team that includes people in no fewer than 3 time zones, I often missed communication when I went home. It took some prodding to get our team onto Slack, but once we were on all, we didn't look back. Slack's support of custom bots was, ironically, one of the determining factors for migrating, but we heavily use the drag and drop interface to share files and images all the time, and also push out GitHub notifications from cli testing into our channels. Being able to pin resources to channels and having the little channel blurb at the top has also allowed us to sub-divide into teams and have critical resources for each team (ticket tracking, zoom link, etc) at the top.
Cons:
I'd say the one downside I feel about Slack is that while they did do a good job improving their search, I still find myself struggling to find things I know I favorited and I can't search favorites. I also wish I was able to tag favorites with my own set of tags.
Great for virtual team collaboration
Comments: Since I use it everyday, I would say this is has become an invaluable tool for me and collaborating with colleagues (w/the exception of not being able to see msg history beyond 10k). I would recommend this to anyone who works virtually OR if you're like me and drown in emails. It doesn't matter if you are in a tech field or not: if you can text an use social media, you can juse Slack. bottom line, it's a WIDELY used tool with a growing number of other app integrations that the paid version allows you to seamlessly tie your [communication] workflow together. I resisted for a while but now I can't imagine not having it.
Pros:
- Slack allows me to commimicate in real time without using email with clients and colleagues all over the country & the world. The free version doens't have as many features as paid, but still robust enough to work for a small 1-man shop - Channels (topics/groups) allow for communication on a topic w/only relevent members (by invitation). preventing tons of emails to track = it's all in one place, in timeline format; this allows you to see who wrote what, when and, whatwas shared (urls, files/photos, etc). - Direct/private chats for more sensitive info - Notification types vary based on your set preferences: when you're mentioned in a channel, indexing keywords. w/hashtags for searching history (like bookmarking). - Video conference calls (paid version allows for up to 15 participants, screen sharing, more storage space & unlimited msgs) - Save comments for later w/reactions or saves to something shared. Clients can be invited to channels and only see that channel's content, allowing things to continue. - File sharing, video calls & integrating with lots of other software/services listed on their site) combines all communication in one tool reducing the need for emails - Cost for the paid plans is relatively nominal and since it elminates the need for emails in many cases, it ultimately pays for itself by saving time + the additional features you get. - Online access to customize your account - Multiple teams (i.e. 1 for your main business, 1 if you're invited, etc
Cons:
Based on my experience using the free version, I find some of the features to be less intuitive = I can't be sure if I can integrate something for a smaller fee or if it's only available in a paid plan. Since many chats tend to grow over time, the free version limits you to 10k messages; you'd be surprised how fast that gets used up. If you try to search for something once you exceed 10k msgs, you may not have access to it. (I get it, it's the free version but it's like texting for business. 10k is small in grand scheme of things so you have to remember to save things you really think you'll need or you'll lose them.

Slack Must Be the Most Useful Communication Tool of the Modern Era!
Comments: Slack has allowed me to improve work relationships and provided a bridge to access different organizations in the same place, from freelance to more traditional enterprises. It has also been extremely helpful to communicate with fellow students at one university, as this is the chosen tool for all generic communications. Because it makes it easy to share code, images and videos either directly on the platform or through third-party services like Google Drive and Dropbox, it has enabled our teams to work more effectively and gather resources in one central spot. And because the search function is quick and offers different filters to narrow down the results to specific channels or members, it's easy to find what you are looking for. It has worked incredibly well for groups of hundreds of people connected at once with perfect synchronicity. Having the ability to stay updated on the fly thanks to the mobile application is also a great advantage that comes in handy more than once.
Pros:
I really enjoy how flexible Slack allows you to be by creating any number of channels you may need to break down conversations per topic. Beyond having the ability to create and join channels based on your needs, the feature to star items is particularly helpful when you are on the go and want to come back to a specific point in time quickly. It is easily accessible with just one click (or tap on mobile) and makes it easy to remember key conversations that are happening. Slack also integrates brilliantly public conversations and what's called "direct messages", enabling you to have private conversations with any member within the organization, hence avoiding the need to use an additional platform for this specific purpose. There is also a neat and practical solution brought by Slack apps, which add even more features including the ability to share polls with Polly, integrate with GitHub, share files stored on Google Drive and Dropbox, which are the apps that we use the most. Being able to control notifications precisely, automatically snoozing them when you are unavailable, makes for a more peaceful experience when dealing with hundreds of members. There are also other features that make you life better, such as the many keyboard shortcuts and the built-in commands you can fire up directly from the reply area, including formatting options and interactions with Slack apps.
Cons:
On the down side, I have found it somewhat confusing to get to set up Slack within other services through their API, for instance to connect Slack on GitHub. Although the reply area is feature-rich, some functions like text formatting could be more intuitive. For example, you don't get to see live if your text will be bold or italic. Slackbot is useful to ask simple questions, but many times it will provide answers that are too simple and could easily be improved. Once again on formatting, Slackbot doesn't explain how to format "code" snippets in-line or even on multiple lines. Many hidden features can only be found by looking online in the "Help Center" or by trial and error, which is not as practical as being able to ask questions directly to Slackbot which should be able to handle those requests. I have also found the desktop application to simply be an exact replica of the web application. Apart from the fact that it adds a little Slack icon in the notification bar, I find it even less intuitive to use than the web application, as it requires to open a new tab in the web browser to sign in. By not being completely independent from a web browser, it basically just results in having a separate web browser that can only handle one tab, which makes it rather inconvenient, especially considering that notifications are well integrated in the web version and that you can "pin" tabs in most web browsers to keep Slack one single click or keyboard shortcut away.

Communication for (Cool) Professionals
Comments: 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.
Pros:
I 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.
Cons:
The 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.
