Pros & Cons from Real Users Pros Slack is like a virtual office space where you can interact with all company members. You can add apps to it, you can create your own apps, you can link it to right about any software out there. Slack is very user friendly and keeps all team communication in one place. I liked how easy it is to find messages, share files, and stay connected with coworkers. Channels are impeccable for keeping conversations organized. Terrific for instant files and documents sharing. Great notification to keep us updated all the time. I like how it boost team collaboration through messaging,video conferencing and live chat. I also like how it saves time while joining chats. Amazing customer support. I found Slack as a perfect tool for collaborating and integrating other project tools. The interface is clean and the best part is it's available on cross platforms. The setup process was straightforward and it allowed me to create a custom channel to share files, discuss and track progress related to my project with assigned groups. Cons It takes some time getting used to its environment. Too many channels and notifications can sometimes feel overwhelming. When there are many channels and active conversations, Slack can feel cluttered and hard to keep up with. Effective with notification for quick updates on changes. I have nothing to dislike at the moment since Slack is absolutely amazing with it’s work. I had a great experience with Slack, no major cons.
