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.

My time with Slack

My overall experience with slack was beneficial when communicating with other team members during the process. When you take the time to figure out the organization process, and receive instruction on how to use the software than things seemed to run smoothly.

Pros

When using slack to communicate with former employers and coworkers in training I noticed it's efficient communication tools. One example of this is that you can operate the program by creating different channels. Operating in different channels is key to organization when you want to transition from different communication sources between individuals. Another important feature that slack offers is file sharing. File sharing allows you to share with others, and you also have the choice to file share with another privately. The program seemed to operate smoothly without any glitches. Slack is a great way to communicate and is suggested for Employer's new hires.

Cons

The only disadvantage I have had by using Slack were minor annoyances when finding some of my former conversations. I also feel that many icons made my scrolling around the program disorganized.

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.

Great tool that allows us to practice what we preach when working with our clients

My company is small and started using it this year. The rollout has been smooth in some cases and bumpy in others. The biggest problem I run into is other users not knowing how to use it. However, as we train each other and our clients, it gets a bit easier everyday and is incredibly.

Pros

There are many things i like about it!
-How many apps it integrates with
-That I can manage projects both internally and externally and communicate freely
-All of the templates are helpful and good quality - many of them are perfect right out of the gate
-That you can communicate via threads so the main message board remains clean and not bogged down with a ton of back and forth
-That you can choose which parts of threads you want to post to the comment board if needed.
-The ability to create workflows

Cons

There are a couple of things I don't like:
-With workflows, you can't create conditional steps. For example, if I want to create a form where the questions change based on the answer to the prior question, you aren't able to do so. You essentially have to make additional workflows/forms for each.
-It gets a bit messy, even if you're great at setting up notifications, channels, communicating through it etc., it can get out of control quickly. Plus, you also have to rely on other people's knowledge on how to use the tool. If someone you're communicating with doesn't know Slack well, you can't be sure if they'll understand how to check for message, have proper notifications etc.

Our remote team loves slack!

My remote team loves slack! So much easier to use than Gmail's chat feature! We love that it is easy to use on our phones, too!

Pros

I love that I can easily communicate with my remote team, schedule impromptu video calls, and integrate apps! I also branded our slack channel to our company's brand!

Cons

Slack will notify you with notes about your apps, tags, etc. It can get confusing if you get a lot of notifications (ex. a note that your google drive file might not be accessible to everyone in the channel). You have to close out the notification to remove it from your channel feed. It's only visible to you, but still annoying!

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.

It is more than satisfactory as a communication tool.

As a communication tool, the overall quality is excellent, with no need to worry about bugs. It offers various features, and it’s up to you how to make use of them. By integrating with desired apps, we could automate certain tasks within Slack. For large organizations, Slack alone can serve as an assistant, making it an excellent tool for time management.

Pros

I liked that members who joined a channel could freely invite other members.

Cons

I found it challenging to understand the Connect feature because the rules seemed unclear when it involved admins.

Great platform with room to grow

Overall, it is a great messaging platform, far above the competition. Could definitely improve on some things, but great nontheless.

Pros

User experience, connecting with other companies via Slack Connect. Also Huddles are a great feature.

Cons

Automation is a bit tricky. Managing User Groups and default channels have been a pain point as well.

Alternatives Considered

Google Chat, Discord and Microsoft Teams

Reasons for Switching to Slack

Slack is a better product than the alternatives. It is easier to use and more accesible for our employees.

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.

Great software for communicating.

I used it on an everyday basis, and it was great. The messages come through right away and I never missed a message while at work.

Pros

It is very easy to use, the set up is very intutive. You can have multiple chats and it is easy to see which chat has new messages.

Cons

I honestly don't have any. I loved using Slack for team communication.

Easy communication for anyone anywhere

Slack is the best communication tool that I use, and I haven't thought about moving away from it.

Pros

Slack is a super easy platform to communicate on, whether with family, friends, coworkers, and professional communities. I use Slack every day for all of the above, and it keeps me connected whether at my desk or on the go.

Cons

Some of the best features are behind a paywall, like keeping messages after 90 days.

Good communication history with potential overwhelm

Slack has become a mainstay for many of my consulting clients. It is a great to archive multiple conversations, and I've used it long enough to pull up discussions from years ago. Very helpful!

The challenge is two fold: Notifications and communicating across platforms. The notification system defaults to sending you a message every time someone else reaches out to you or contributes to a message thread. This can become overwhelming, especially when other contributors are adding sidebar or inconsequential content to the thread. Expect to spend a lot of energy turning notifications on and off. Secondly, it can get frustrating when you get a notification on your Slack app, but want to reply on your laptop, or vice versa, and Slack requires multiple logins/email verifications to get you back in. It becomes even more convoluted when you are part of multiple Slack channels and it logs you into the wrong one.

It's a great archival platform, especially among large team projects or for folks like myself who work with various groups. For daily use, though, expect to spend energy managing notification and log-in fatigue.

Pros

The archiving of conversations is fantastic.

Cons

Communicating on Slack across multiple platforms can be confusing and exhausting.

Alternatives Considered

Google Chat and Discord

Reasons for Switching to Slack

Excellent conversation archiving and tagging.

Great experience

Again, I had a great experience using Slack. It's affordable, easy, and helpful. I very much prefer using Slack to relying on emails and texts.

Pros

Slack is helpful because connecting is easy and organized. When I see a notification from Slack I know it's business related without checking it. It's easy to attach files and I can record audio or video messages with one tap. Everyone I work with was able to sign up in seconds. Most of us were actually able to sign in with the same account used to download the app. Our profile photos from those accounts automatically synced so it's easy to see who is saying what in the thread/channel.
Canvases are helpful too, they're basically like a white board that everyone can see and edit.

Cons

As far as I know, Slack doesn't have two way audio or video. You can record and send either, but it's not live. I wouldn't use it a lot anyway, however if you do then that may be something to consider.
If I need to search for a message, I have to do that from the home screen. There is no search bar within the channels or DMs.
