How does Slack work? Your beginner's guide – TimeDive

Slack has become one of the most popular communication tools for teams and businesses worldwide.

But if you're new to Slack, you might be wondering: How does it actually work?

In this beginner’s guide, we’ll break it down step by step, covering its key features, how teams across the world use it.

What is Slack?

Unlike traditional emails, Slack brings all your conversations, files, and tools into one place, making team communication faster and more efficient.

Whether you're managing daily work, discussing ideas, or simply checking in with your team, Slack helps streamline work and reduce the clutter of endless email threads.

How Slack works: key features explained

Here’s a detailed breakdown of how Slack works and its most important features:

1. Channels: organize team conversations effectively

Slack uses channels as the primary method of team communication. Channels are like dedicated chat rooms for specific topics, projects, or teams.

• Public Channels – Open for anyone in your Slack workspace to join, ideal for company-wide discussions.
• Private Channels – Restricted to selected members, perfect for specific departments or project-specific conversations.

🔹 Example: Your marketing team might have a #marketing channel, while your developers use #engineering.

2. Direct messaging: private conversations

You can also send direct messages (DMs) for private one-on-one or small group conversations. These are great for quick check-ins, confidential discussions, or casual chats.

🔹 Example: If you need a quick update from a colleague, simply DM them instead of sending an email.

3. Integrations: bring your favorite tools into Slack

One of Slack’s biggest strengths is its ability to integrate with other apps. They have an app directory and you can connect Slack to tools like:

• Team Productivity tools (TimeDive)
• Project management tools (Trello, Asana, ClickUp)
• File sharing apps (Google Drive, Dropbox)
• CRM software (Salesforce, HubSpot)

These integrations help you manage projects, track tasks, and collaborate - all within Slack!

4. Search: quickly find what you need

With Slack’s powerful search function, you can easily find messages, files, or conversations from past discussions.

• Search by keywords, file names, or users
• Use filters to narrow down results

🔹 Example: Need that report your manager sent last week? Just type relevant keywords in the search bar instead of scrolling endlessly.

5. Slack connect: collaborate beyond your own team

Slack isn’t just for internal teams - it also allows you to collaborate with external partners, clients, or vendors using Slack Connect. They are added as a guest user in your Slack workspace. This feature lets you share channels with people outside your organization while keeping discussions structured and efficient.

🔹 Example: If you work with an external agency, you can create a shared channel under “External connections” section

6. Workspaces: your team’s digital office

A Slack workspace is where all your team members communicate. Each business or organization typically has its own Slack workspace, containing multiple channels and direct messages.

🔹 Example: Your company might have a Slack workspace named CompanyXYZ inc, with different channels for departments and projects.

7. Slack etiquette: best practices for efficient communication

To keep Slack productive and organized, follow these best practices:

• Use threads – Reply to messages in a thread to keep conversations tidy.
• Keep messages concise – Use bullet points or line breaks for readability.
• Use emoji reactions – Instead of typing “Got it” or “Thanks,” use an emoji reaction to acknowledge messages.

🔹 Example: If someone asks a question, respond in a thread instead of starting a new conversation.

Here's a detailed guide explaining how to keep your Slack workspace tidy.

8. Notifications: stay updated without distractions

Slack allows you to manage notifications based on priority:

• Mute channels that aren’t urgent.
• Set Do Not Disturb (DND) mode when you need focus time.
• Customize notifications so you only get alerts for @mentions or specific keywords.

🔹 Example: If you need deep focus, you can turn on Do Not Disturb for a few hours.

9. Paid plans: unlock advanced features

While Slack offers a free plan, paid plans provide extra benefits like:

• Unlimited message history (free version limits how far back you can search)
• More storage for file sharing
• Advanced security and analytics

🔹 Example: If your team needs access to older messages or integrations with more apps, upgrading might be worth it.

You can continue to use it for free with certain limitation (access to chat history not older than 90 days)

10. Free trial: try before you commit

Not sure if Slack’s paid plans are right for your team? You can try a free trial to explore premium features before making a decision.

🔹 Example: Sign up for a free trial to see if features like unlimited message history and enhanced security make a difference for your team.
