Understanding Slack

Slack is a communication platform designed to help teams collaborate through channels, direct messages (DMs), and integrations.

While most instant messaging apps have conversations scattered, Slack organizes these discussions into channels based on specific topics, ongoing projects, or team members, making it easy to find the right conversation history when needed.

Businesses widely use it for:

  • Real-time communication through instant messaging
  • Organized conversations within dedicated channels
  • App integrations that streamline workflows, reducing context-switching
  • File sharing for documents, images, and other files
  • Searchable archives that allow teams to find past conversations, files, and decisions
  • Custom notifications to reduce overwhelm

Mastering Slack’s features will ensure your team’s communication strategies remain seamless and effective.

How to Add Someone to a Slack Conversation

Now that you know what Slack is all about and how it fits into your organization, it’s time to master a key skill: adding someone to a Slack conversation in the correct way. 

No more guessing or awkwardly starting a new group chat when you don’t have to! Let’s break down the two best ways to do it.

Adding someone to a Slack Channel

Adding someone to a Slack channel gives them instant access to ongoing discussions, past messages, and key project updates. You no longer need to forward messages to get them in the loop. 

Here’s how to do it the right way:

1. Open the channel to which you wish to add a new member.

via Slack

2. Click the channel name at the top of your screen to open the conversation header.

3. Select “Add people” from the dropdown menu.

4. Enter the team member’s name or email address and click “Add” to include them in the channel.

5. Confirm their access to ensure they can view the conversation history and participate in ongoing discussions.

💡Pro Tip: Anyone can be added to public channels, but private channels require admin approval or access permissions.

For example, if you’re discussing a marketing campaign in a private channel, adding the right team member ensures they have the necessary context to contribute effectively.

Adding someone to a Direct Message

Need to loop someone into a direct message without jumping through hoops? Turning a one-on-one chat into a group conversation is perfect for quick discussions; no need to start a whole new channel. 

Just follow these straightforward steps, and you’ll have the right people in the right chat in no time:

1. Open an existing direct message. Navigate to your list of DMs and select the one-on-one conversation where you want to add another person.

2. Now, access the Open conversation details panel. Click on the three-dot icon on the top right of the conversation window to open the menu.

3. In the details panel, look for the Add People button. This will allow you to expand the conversation into a group DM.

4. Search for the person to add. Start typing the name or email address of the person you want to add.

Search by name or email


5. Once the person’s name appears, select it and click Next to confirm their addition and finalize the process.

6. A new group chat with the added teammate will now open up. This will keep the direct conversation with the original person intact, ensuring you do not lose any prior messages or sensitive information.

Quick Hack: A good practice is to inform the new participants they’ve been added to a new group. This will avoid confusion and maintain context.

Imagine you are finalizing a proposal with a teammate and need input from your manager. Expanding the DM to a group chat seamlessly integrates your manager into the ongoing conversation, keeping everyone aligned.

👀 Did You Know? Slack was originally a gaming project! Before it became the team communication app we know today, Slack started as an internal messaging tool for a video game called Glitch, created by Stewart Butterfield’s company, Tiny Speck.

Common Problems and Limitations in Slack

Slack is a great communication tool, but sometimes, using it can feel like you’re drowning in messages, files, and notifications. Let’s look at the common issues that could make Slack feel less like a productivity booster and more like a challenge.

❌ Message overload 

Using Slack can quickly become overwhelming with constant message notifications, especially when you’re in multiple channels. It’s easy to lose track of important messages amid the influx of casual chats, updates, and discussions. This can result in missed deadlines or vital information getting buried in the mix.

❌ Limited file management

Managing files in Slack can be frustrating, as there’s no dedicated file storage area. While you upload files to channels, they quickly pile up and become hard to locate later. Searching through old messages to find a specific document or file—mostly possible if you remember the exact name—can take a lot of time.

This makes file retrieval tedious, wasting time and adding to frustration.

❌ Channel clutter

Slack channels can quickly become chaotic and add to the clutter. Even when trying to keep channels organized, locating the right channel in the noise can be a task.

❌ Notification overload

Slack notifications can be a distraction if you’re in many channels or workspaces. The constant pinging can make it harder to focus on deep work. A quick Slack hack is to set custom notifications, allowing only crucial messages to come through. However, you risk losing track of other important messages.

❌ Lack of formal project management features 

Slack is great for quick chats and team updates, but it falls short when it comes to tracking tasks and deadlines. There’s no built-in task board, Gantt chart, or structured workflow, so managing projects can get messy. Most teams integrate Slack with other task management tools to keep everything on track.

💡Pro Tip: Slack’s search function will help you find past files and messages, but using specific keywords and filters will give you the best results. Consider organizing your channels and messages to make things easier to search.
