What is Slack?

Slack mobile apps

Slack is an online communication tool designed for teams working together around the globe. Communication in remote teams has been a hassle. Slack brings everything a team needs to communicate effectively. 


From chatting with your Slack team members to sharing files, taking notes, scheduling meetings, and having water-cooler chats, the Slack interface enables you to do everything without missing your office.


It brings together everything a business needs to grow, such as teams, conversations & discussions, data, your favorite apps, and other tools. It works like a dedicated company chat room where all of your team members can send direct messages, share details, make jokes, and create interest-specific channels to have fun. 


How Does Slack Work?

Key Features of Slack

Hassle-Free Communication

Communication in Slack

Seamless communication with the entire team is the foremost feature of Slack is being used. Regardless of your timezone and geo-location, you can send and receive private messages to your team members in personal chats or direct messages.


Slack members can also set their statuses such as working remotely, out of the office (OOO), or any other. This status helps people know the availability of the person. 


You can set a date range for each status you choose. The status will be changed after the completion of the date range. 


Other quality features to improve communication, include:


  • Channels: You can create separate channels for different purposes. However, for teams working together, you can add employees in both channels. These channels can also be created for important information, fun, water cooler chats, and sharing industry information. 
  • Texts to Yourself: Whenever you need to take a note or remind yourself about something, or any other detail you want to save, you can text yourself in the Slack app. With this feature, you can access the information in a matter of minutes without going through a long history of texts. 
  • Pinning Messages: Finding a keynote or important detail shared between messages is difficult. Slack resolves this issue with the pinning feature. This lets you pin any important message or detail to help you find it quickly whenever you need it. For example, we sometimes share login information of tools that we use. Our team members can easily find such details from the list of pinned messages. 
  • Audio/Video Calls & Slack Huddles: Not just written communicating, Slack is setting a benchmark for remote team communication. There’s a voice note feature that helps you record and sends your message quickly. You can also hop on a quick call and discuss things on a video call. Nothing of it requires you to use a different app. 


Advance Search Modifier

Slack lets you share all important files of any type and format with your team. However, finding them in channels and messages could be difficult. 


With an advanced search modifier, Slack enables you to look for important data, whether messages, files, links, or images, using a key term or keyword you specifically used for the data. 


On search, you will get a list of matching terms. From this list, you will be able to easily pick the file/link/message you are looking for. 


Shared Slack Channels

Sometimes, the in-house task force is not enough to complete a project. For this, companies hire freelancers or contractors to help complete the project. 


Inviting these short-term employees into the workspace sounds a little too much. With Slack, you can create dedicated channels and invite all people working on the project, in-house employees and contractors, to collaborate. 


This also applies to public and private channels. For example, the channels created for managers to share company information are not supposed to be accessed by any other team member. For this, you can set this channel to private. 


This feature lets you have control over who can access the channel. 


Smart Shortcuts

Shortcuts make things quick and easy. Repetitive tasks like setting reminders should be automated. If not, then it should be quick enough to not take minutes, but seconds. 


In Slack, you can set reminders of important tasks and deadlines with the “/remind” command. This command will open up a reminder window to let you add details like time, date, and reminder detail. 


Slack Workflow Builder

Workflows in Slack are a quick way to get your routine tasks done. You can create workflows without using a single line of code for simple and complicated tasks. However, before getting into it, you need to decide on the following four things. 


  1. Trigger: This is the action to get your workflow started. A trigger is the starting point, for example, if x happens, the workflow should get started. The x here could be any action. 
  2. Step: You need to think about the process or steps of the workflow. For example, if x happens, the person will be directed to a certain form or page. 
  3. Variable: Depending on the answers selected in the steps, each person will be directed to a different journey ahead. 
  4. Collaborator: The person with access to permission to manage your workflow can change, modify, and remove steps or the workflow. 


Slack has some pre-made workflow templates to help you get started. You can use any of the existing templates or create one from scratch. 


Slack APIs

Sometimes, businesses need unique solutions to their needs. Many businesses rely on workflows and app integrations, but some firms need a set of features specifically designed for them. 


For this, they hire developers and engineers to help them craft better solutions. Slack APIs let those developers turn their ideas into useful solutions. 


It means you can build your own apps and integrate them right in the Slack workspace. Though, for many businesses, this feature is not in use. But where needed, it saves a ton of time and energy and improves work efficiency. 


Enterprise-Grade Data Protection

Slack is known to be popular among high-performing companies as well as growing businesses. But regardless of the size of the business, data protection and security is important for every business. 


For this, Slack offers a universal solution to all its users with enterprise-grade data protection. It ensures that all of your files, important data, employee details, and other stuff is safe and secure. 


Slack Integrations

Though Slack is offering a wide range of solutions, we all use several other apps for our business processes. Shifting tabs to use information can seem like the only option but Slack lets you integrate all of your favorite apps. 


Integration makes it easy to access data acquired through different apps on a single screen. As of now, Slack offers 5,000+ app integrations from different categories. 


Some of the most popular apps Slack integrates with:
