"The communication tool you can't do without"

Comments: Slack has improved our communication workflow with our team and improved the way we interact with clients. It allows for multiple language to be spoken by using some translation tools, thus including more staff and especially non-english speaking staff.

Pros: Slack is a great collaborative software that helps users to collaborate across cities, countries, and timezones. It is a crucial part of our project workflow and helps to let developers, project managers, and clients speak to each other in a collaborative enviroment. It has numerous integrations that allow for third-party apps to interact, create, and receive messages and alerts. These integrations allow us to have one place in which all communications can flow and makes it easier for a worldwide team to be up on the latest updates and critical alerts that may happen.

Cons: The slack tool can be a little battery intensive, especially as you add more slack channels. It also gets quite expensive as you add additional paid members to the group. If you are not aware of all your paid members, or you add guests as paid it can get very expensive quickly. Because this is a discussion, it is also possible that critical conversations can get lost in the stream of texts coming through.

"I sometimes wonder how collaboration worked before Slack"

Comments: I find it hard to remember life before Slack. We all worked in a single open plan office but, like most offices, still communicated predominantly from our desks. Our go to IM tool was Skype and it was an easy way for conversations to get siloed. Slack brought those conversations out into the open, made them discoverable and brought in automations to make them richer. If you're debating whether to use Skype or Slack there really is no contest. I'd also suggest it outperforms Teams and other competing collaboration and instant messaging tools for it's deep integrations.

Pros: Real-time instant messaging, file sharing and integrations with key apps that automate important proceses mean a high percentage of tasks can be managed all in one place.

Cons: Threads are often difficult to keep track of. Slack has done its best to elevate Threads but I still find myself missing things when people don't @ mention me.

"Slack : A very quick review"

Comments: Slack improves correspondence among colleagues. In spite of the fact that it doesnot supplant the need of email yet yes it clearly reduces unnecessary inside messages Slack stays a standout amongst the best group informing applications since it offers more than some other application in this classification. For a variety of devices and platforms, Slack is available: mobile Mac, Windows, Linux, Web, Android, iOS, and Windows.
It is a cloud-based tool in real time, so you need an Internet connection to use it regardless of which app you have.

Pros: What I truly like is to discover individuals and ping them and begin a transformation. Most significant, you can share records, photographs, URL, gifs (Very significant), in a solitary spot.
Making joint effort simple and something to appreciate.
at the point when significant data is imparted to other application it gets lost and there is no record of it. With the slack channel, the data is put away and can be utilized as references Slack makes it workable for its clients to have numerous alternatives of getting informed. The best component, as I would see it, is the place somebody can "@" you in a message or a post.

Cons: Below are some points which I least like in Slack: Video calls are just bolstered in the work area applications and Slack for web in the Chrome program. In the event that you join a call from a cell phone, you get sound as it were. So also, screen sharing just works from the work area applications, what's more, sharing control of screen sharing just works in the Mac and Window work area applications (not Linux). From the web application in Chrome, you can watch on the off chance that another person utilizes screen sharing, yet you can't start it. There is also no option for downloading conversations to create a hard copy record (for minutes of meeting, etc.). No File Preview: If you could preview a document without downloading it first, it would be nice. But Slack does'nt have this feature.

"Best app for messaging!"

Comments: Slack is very fun to use and easy to get used to. I think every company should use it.
It’s also very private so only people within the company have access to message you. External users cannot find you or message you. Great software overall!

Pros: This app is very easy to get used to and it’s very customizable. You can choose a color theme or create your own and manage which channels you want muted or you got want to receive notifications.
I also love that they have an mobile app, a desktop app or you can use the web browser to login. It’s a great way to communicate with colleagues 1:1 or by group chats (channels).
You can also generate polls or gifs in the chat bar, respond to messages in a thread to not overflow the chat with responses and react to messages with emojis. I love it. I’ve used it for years!

Cons: Every so often the software does have issues. It’s happened maybe once or twice a year where it crashes for a couple of hours and messages cannot be sent. I think it has to do with the server or something but it usually resolves pretty quickly.

"PERFECT BRIDGE BETWEEN AGENCY AND WORKERS"

Comments: 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.

Pros: As 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.

Cons: When 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.
