Default badge notifications

By default, unread activity will display a red badge on the Slack icon. 

• • A dot means you have unread activity in one of your Slack workspaces.
• 3 A number means a teammate sent you a direct message, mentioned you or notified a channel you're in, or used one of your keywords. 

If you'd like, you can remove the badge from the icon using the steps outlined below.

Set your badge notification preference

1. From your desktop, click your workspace name in the top left.
2. Select Preferences from the menu, then click Notifications.
3. Under Sound & appearance, check or uncheck Show a badge • on Slack's icon to indicate new activity.

Tip: If you're a member of multiple workspaces, you can pick and choose the ones you'd like to see badge notifications for.

For Windows, you'll see badge notifications in two places: in your taskbar and in your notifications area.

Notifications area

When Slack is running, you’ll see a Slack icon in your notifications area.

• A blue badge means there's unread activity in one of your workspaces.
• A red badge means a teammate sent you a direct message, mentioned you, or used one of your keywords.

By default, your app is set to keep running in the notification area even when the window is closed. Choosing not to leave the app running will remove the Slack icon (and badges) from your notifications area. Here's how to do this:

1. From your desktop, click your workspace name in the top left.
2. Select Preferences from the menu, then click Windows App.
3. Uncheck the box next to Leave app running in notification area when the window is closed. 

Taskbar

In your taskbar, 3 a red badge means a teammate sent you a direct message, mentioned you, or used one of your keywords.

By default, the Slack icon will flash once when receiving a notification, but only if your computer has been idle for 10 seconds. You can choose to flash the Slack icon even when you're active: 

1. From your desktop, click your workspace name in the top left.
2. Select Preferences from the menu, then click Notifications.
3. Under Sound & appearance, check Flash window when receiving a notification. 

Tip: To keep the Slack icon in the taskbar when the app window is closed, select Flash window when receiving a notification, but leave the second option unchecked. 

Note: If your taskbar is set to small taskbar buttons, badges on the Slack icon will not be visible.

On Linux, you'll see badge notifications in your notifications area when the Slack app is running.
