About Slack

Slack is a cloud-based project collaboration and team interaction tool designed to facilitate communication across organizations. The solution caters to various industries, including media, research, technology, education, financial services, retail, transport, and logistics. Slack provides public channels for members across organizations to start conversations. Private channels enable interaction within smaller teams, and direct channels help send messages directly to colleagues. Slack incorporates feeds from social media into the application and blends them with ongoing conversations in various channels. Files such as PDFs, images, documents, and spreadsheets can be shared via drag and drop. Slack archives messages, notifications, files (as well as the contents of files) and projects, all of which can be searched for later. Slack allows users to customize their notifications and reduce their scope. All changes are reflected in the native applications available for iOS and Android.

Slacktopia: Simplify Your Interaction

Overall, I've had nothing but great experiences with Slack. It's a really helpful platform for project management, teamwork, and communication. It is an invaluable tool for increasing productivity and encouraging teamwork because of its user-friendly interface, wide range of customisation options, and smooth connection with other programmes. But sometimes it might be difficult to handle notifications and information overload; it takes careful planning and moderation. Slack is still a vital tool for contemporary workplaces in spite of this.

Pros

The best thing about Slack, in my opinion, is how easily it integrates with different communication channels and has an intuitive UI that makes it simple to share files, remain in touch with coworkers, and work efficiently in real-time. Its extensive app integrations and customisation possibilities also improve productivity and simplify workflows.

Cons

Slack's potential for information overload, especially with regard to channels and notifications, is a disadvantage that can occasionally result in decreased focus and distractions. Additionally, without appropriate planning and communication channel control, managing big teams or complicated projects can become difficult.

I am a professional developer who has used Slack for around 5 years

I enjoy how Slack is in a unique space of being the preferred messaging platform for software developers, both enthusiasts and professionals. It is modern & feature-rich enough to fit both personal and professional use. As mentioned earlier, the adoption on the professional side lags behind similar tools. I’ll finish by saying one of the most versatile features that Slack for Enterprise has built is the workflows/automation feature.. and it should continue expanding on this feature to outpace it’s competition.

Pros

The interface and integration capabilities of Slack are several times more modern than similar messaging tools.

Cons

Slack has more work to do to overtake market share in Enterprise use cases, meaning those professional teams who are already integrated into the Microsoft environment and prefer Teams. It is often the case where Slack is used on the side, as an addendum, to a team that is already using a different communication platform. I guess this kind of problem would be best remedied by better marketing & outreach to promote Slack’s features and ease.

No longer worth it

Good for a while but the product only really got worse with time. The massive price increase meant we could no longer trust them with our money or data so we left and we don't regret it at all.

Pros

A lot of products integrate easily with Slack. As a replacement for Skype it was quite good.

Cons

Rug-pull price increase forced us to migrate. We found Zulip which ended up being better in practically every way.

A solid option to centralize communications

I have been using Slack since around 2016 or 2017. It's been long enough that I don't remember exactly when.

Pros

Communication is seamless. Even though it is an instant messaging product, it lends itself surprisingly well to transactional communication as well, effectively replacing email for most use cases.

Cons

Search is painful. Notifications with channel membership takes some work to get right.

Slack is the internal chat tool for any business

Great piece of software that does what it sets out to do very well. We've tried Teams, Hipchat, RocketChat and Slack is by far the best.

Pros

We are a prodominently remote business now and what stands out most about Slack is its ability to centralize communication in a way that makes teamwork seamless. The channels allow for organized discussions around specific topics, and the integration with other tools makes it easy to streamline workflows. It makes collaboration feel more dynamic because you can react to messages, share updates in real-time, and even automate some tasks to save time.

Cons

One of the things I like least about Slack is the potential for information overload. With so many channels, threads, and messages, it can sometimes feel overwhelming to keep up with everything, especially if you're part of a large team or working on multiple projects at once. Notifications can pile up quickly, and it’s easy to miss important messages buried in a sea of conversations.

Great for Team Communication, But Room for Improvement

Slack has been useful for my team's asynchronous communication needs, but definitely lacks some of the functionality we need for maximum confidence in our communication.

Pros

I love that it has a free version and allows video, audio, text, and pictures for communicating with my colleagues. It's a good way for our remote team to stay connected.

Cons

I do not like the inconsistent notifications and the way threads work. My team has missed important communications way more often than we have with other similar apps.

My favorite corporate messenger

I’ve been using Slack for about 5 years. Before that, I tried two other popular corporate messengers. In my opinion, Slack is the best corporate messenger on the market.

One of the best features is its integration capabilities. For example, we integrated Slack with our web application, so now we receive instant notifications in Slack whenever a critical issue arises, allowing us to react immediately.

I also use Slack for saving project-related notes. It’s convenient to keep everything organized and easily accessible in one place.

Pros

Slack is incredibly user-friendly and makes it easy to manage multiple workspaces, enabling simultaneous communication both within my company and with customers. I especially like the threads feature—it helps keep discussions organized and makes it easy to find information when needed. I also like the customizations and automation you can set up, which saves time.

Cons

I use Slack on both my phone and laptop, but sometimes I have an issue where I can’t answer a call on my laptop because it’s active on my phone instead.
Also, sometimes when a colleague calls me using Apple headsets, I can’t hear them.

Powerful tool for team communications

Powerful tool, well known and used by those inside and out of our organization.

Pros

Our company communications have been built on Slack - the ease of use and increasing features available have helped us grow and manage communications (both internally & externally).

Cons

The cost is somewhat steep, especially as the team grows. Was recently notified that they were adding a limit to 10 connected apps and would charge us 40% more if we had over 10 (this is down from the previous ulimited). Though they quicky changed their mind. Lead to a fair amount of wasted time internally assessing connections.

Overall positive

Overall, my experience with Slack has been very positive. It’s an essential tool for team collaboration, especially in remote or hybrid work environments. It helps keep communication efficient and organized through channels, direct messages, and integrations with other apps. While it can sometimes be overwhelming with notifications, setting clear boundaries and customizing alerts helps manage this. Slack has definitely improved how our team communicates and stays connected.

Pros

What I liked most about Slack is how it keeps communication organized and accessible. The channel system is great for separating topics or projects, and the integrations with tools like Google Drive and Trello make it easy to streamline workflows without switching apps. The clean and intuitive interface also makes it easy to navigate, even for new users.

Cons

One downside of Slack is the potential for notification overload, especially in larger teams where messages can pile up quickly. It can sometimes feel overwhelming to keep up with everything. Additionally, while the search function is helpful, it could be more intuitive when trying to locate older messages or specific files in busy channels.

Pros

I like that it is easy to edit a message. I like the ease of posting anonymously. I also love that there are loads of groups. Finding a link within chat is also good, so I would say overall their search functionality is good.

Cons

Perfect for team collaboration - internal and external.

I've used Slack with several organizations, including a non-profit and marketing agencies. We used it to do internal planning and also planning with the client in a channel dedicated to them.

Pros

Slack is great for working with internal teams and with external guests. I like that you can create lots of channels for specific topics or teams and that you can reply to comments in an individual comment replay thread.

Cons

I can't think of any Cons. Slack's functionality is great and works very well.

Favorite messaging platform out there!

Pros

To start, the easy to use interface is a HUGE benefit. If you have ever used any messaging platforms before, jumping into Slack will be seamless. It is intuitive and streamlined. I also love that it keeps all communication in one place - whether that be huddles, group chats, one-on-one conversations, or channels. Everything is easily searchable. Slack really improved its functionality when it added the ability to do calls a few years back.

Cons

Overall, I am thrilled with the platform. I love that it offers a free plan, but the paid are a bit pricey compared to others in the market. Also, the limited users available in a huddle is a bit of a con but not large enough to deter me from recommending Slack.

Transforming Team Collaboration with Ease

My overall experience with Slack has been excellent. It has transformed the way our team communicates, allowing us to stay connected and productive even when working remotely. The platform fosters a sense of collaboration and ensures that everyone stays updated. While there are minor drawbacks, such as notification management and storage limitations, the benefits far outweigh them. I would highly recommend Slack to any team looking for an efficient communication tool.

Pros

What I like most about Slack is its intuitive interface and the seamless integration with other tools we use daily, like Google Drive and Zoom. The ability to organize conversations into channels makes team collaboration efficient, and features like reminders and scheduled messages help keep everything on track. The search functionality is a lifesaver when looking for past discussions or shared files.

Cons

What I like least about Slack is the notification system. It can become overwhelming, especially in large teams with multiple active channels. Although there are settings to mute channels or customize notifications, it still requires constant adjustment to avoid distractions. Additionally, the free plan has limited message storage, which can be frustrating when trying to access older conversations.
