Slack Overview
What is Slack?

Slack is the top choice for teams to communicate. It provides a virtual workspace that helps teams maintain open communication in a business environment. With Slack, users can host voice and video calls with up to 15 participants and even screen share with a desktop app, empowering better user interaction. Slack also supports options for private and group sessions, and one of its best features is Slack Huddles–an informal meeting space that lets you directly talk to your channel where you can share screen side by side with your team. The platform integrates well with Dropbox, Google Drive, and Trello as well.

"Excelente herramienta de comunicación para equipos distribuidos y remotos"
What do you like best about Slack?

Que es súper facil comunicarse con el equipo de trabajo, ya sea con un miembro o por un canal con diferentes grupos por diferentes temáticas de trabajo. Usamos Slack todos los días todo el día. Usamos las reuniones con voz y compartimos pantalla. También la usamos como repositorio de información para buscar temas. Se puede integrar con varias herramientas como Asana, lo que permite un mejor seguimiento de las tareas. También me gusta la manera de compartir archivos en los grupos y el manejo de estados que permite la herramienta.

What do you dislike about Slack?

No hay nada en particular que me desagrade de Slack, lo único que podría sumar es una agenda de reuniones.

What problems is Slack solving and how is that benefiting you?

Slack resuelve la comunicación con el equipo, tanto como chat para compartir informacion y comunicarnos diariamente, tanto 1 a 1 como canales de grupos, como tambien nos soluciona la necesidad de reunirnos para hablar y compartir la pantalla. Es realmente una herramienta esencial para el trabajo de equipos remotos y distribuidos.

"Obsessed with this tool!"
What do you like best about Slack?

Slack is the best enterprise communication platform out there. It integrated with so many apps in order to elevate the user experience. Love the emojis and gifs available, such a great way to make the workplace a little more fun and personalized. I use it all day long for work and even on weekends. It's a great way to communicate both for projects and for fun (donuts)

What do you dislike about Slack?

So many commands and automations to use, I feel like the Slack team could make availble more walkthroughs in order to accelerate the full potential of the platform for users.

What problems is Slack solving and how is that benefiting you?

Great way to connect internally with my coworkers, no more emailing and inboxes! Slack is much more user friendly.

"Awesome messaging tool for both external and internal communication"
What do you like best about Slack?

Well, it perfectly integrates with the tools that most of the SME and large enterprise uses, such as HubSpot zapier etc

What do you dislike about Slack?

Nothing as such but the UI could be much more better

What problems is Slack solving and how is that benefiting you?

So, if i want to document any action items and share it amongst members that are associated i can simply create a group and do it, we use HubSpot extensively so we need to know any roadblocks that our customers are facing instantly so it has integration and automation which enables notification and makes us aware of such cases instantly

This has been one of our super favorites. We use this to communicate internally in our organization. Simple, straightforward, highly functional and it has a nice look.

So far, Slack has allowed me to do everything I want to do using it. By sending files or just plain messages, Slack serves it purpose very well.

"Experience with Slack"
What do you like best about Slack?

The ease of use, good communication features, the external integrations, the general application vibe

What do you dislike about Slack?

There is nothing I can think of about Slack that I don't like

What problems is Slack solving and how is that benefiting you?

Slack allows immediate communication between the company users. It provides transparency about my co-workers and their association with the company. With it's channels and grouping features, it allows to organize based on any category as per the users needs. I particularly like the threads feature as it allows to have a continuous conversation around one topic while having another in the main chat without any confusion. The application also has fun elements by adding emojis and reactions and gif integrations and theme customizations. The integrations between multiple external applications allows to keep track on a lot of things under one umbrella.

"Fun tool!"

That you can easily stay connected to co-workers and friends remotely

What do you dislike about Slack?

I can't think of anything I don't like; I have not had any issues yet.

What problems is Slack solving and how is that benefiting you?

To be able to stay connected when we are still working remote, and to stay in contact with folks who live in different states. I like how you can make private channels as well for smaller groups.

"Please stop using personal tools for work!!"
What do you like best about Slack?

Personally, the main reason for using Slack daily is that it keeps work related messages in a specific app that I can simply turn off when I'm not working. Thanks to its integrations, I can also automate the workflow and get notified of important events: receiving a new order, an email from a client, the due date for a project/task on Monday, etc. It truly does what it promises: it is a productivity platform.

What do you dislike about Slack?

Sometimes it is difficult to get team members to use Slack if they do not need the automations mostly because they wrongly go for the messaging apps. However, in the long terms, I guess most of them understand the benefits and the easy of use/implementation!

What problems is Slack solving and how is that benefiting you?

Too tired of mixing personal and business messages in the same app. Slack helps me to keep work related messages in a specific place that I can simply turn off when I'm not working.

"I love using Slack for the corporate communication between colleagues!"
What do you like best about Slack?

I have an experience of using slack for more than 2 years in two different companies,therefore I love how easy and comprehensive it is. It gives me the possibility to communicate directly with the colleagues, creating different channels accordingly to discuss the specific topics. With that reason you cannot miss any of the chat/message in the thread. Being a Team Leader, It is extremely easy to integrate with the team members and discuss and make announcements to them in a proper way. Basically, we use Slack frequently, every day. The possibility to record voices, listen to the recording in different regimes and have calls if necessary is an advantage that many platforms do not have. Moreover, I always change statuses and can pause the notifications if needed, not to be disturbed.

What do you dislike about Slack?

Sometimes there are technical glitches and the notifications might not be visible for severa hours. However it appears after some period of time.

What problems is Slack solving and how is that benefiting you?

As a employee of an international company the communication problem is higlhy solved as I can have a direct dialogue with the colleagues not being afraid of the lack of communication with them. They always receive my notifications and are aware of all the announcements made by each other.

"Nothing can replace Slack for Professional Communication"
What do you like best about Slack?

It's the best app for communication within teams or agencies. It is simple and has all the integrations required for a business to operate. We use Slack on a daily basis

What do you dislike about Slack?

Nothing much, we have been using slack for more than 3-4 years now.

What problems is Slack solving and how is that benefiting you?

Slack is our backbone for communication. If we had to do stuff without getting on a call, the chats are always through Slack. If there is a need for any more assistance, we use the huddle option to get on a call. The integrations with Google Workspace are notable and are used every day. The mobile app is also convenient. The days of communication via email is over now.

"A RELIABLE, EFFICIENT INTER-OFFICE COMMUNICATION TOOL"
What do you like best about Slack?

Slack has played a crucial role in connecting everyone in our organization, and I genuinely believe that. As a front-end developer, Slack has made it much simpler for me to collaborate with my team members, share ideas, and discuss the progress of our projects. This has greatly improved the efficiency and effectiveness of our development process. Furthermore, Slack provides integration with various development tools, which allows me to receive notifications and updates directly within the platform. These tools can include version control systems, continuous integration tools, and project management platforms. On top of that, Slack is user-friendly and straightforward to use and implement, thanks to its well-designed interface. One standout feature is the powerful search function, which enables me to quickly find information or references within chat history, thereby saving time and aiding in problem-solving. Thanks to Slack, I can confidently say that my productivity in collaboration and efficiency has greatly increased, thanks to its capabilities and broad range of features.

What do you dislike about Slack?

As you begin using Slack, you may find the app disorderly and overwhelming, causing concern about potential information loss or overlooking important updates. The initial experience can appear chaotic. However, you can overcome these challenges by utilizing the app's customizable settings and seeking assistance from customer support. Additionally, as your team becomes familiar with how to optimize Slack for their requirements and with repeated usage, it becomes increasingly manageable..

What problems is Slack solving and how is that benefiting you?

Every day, we rely on this tool to work together with our team, sharing information about tasks, stories, and project details, as well as communicating in a formal or informal manner. Its system of channels allows me to stay organized by categorizing discussions based on project, task, or topic. This makes it effortless for both me and my team to find the information we need and participate in discussions related to our work.
