Guide to desktop notifications

Slack notifications keep you informed about things that need your attention. Learn how notifications work on your desktop and how to customise them to suit your needs.

How notifications work

When you first join a workspace, Slack will notify you of messages that are for you. By default, here’s when you’ll receive notifications:

These settings apply to both desktop and mobile notifications until you make changes. If you’re having issues, skip ahead to Troubleshooting notifications.

Note: If your workspace has 50 members or less, you'll receive notifications for every new message by default.

Note: Slack won’t send notifications to your desktop and mobile devices at the same time. Learn more about mobile notification timing.


Configure your notifications

The default desktop notifications are automatically enabled as soon as you join a workspace. Use the steps below to customise your preferences.


Notification triggers

By default, only @mentions, direct messages and keywords will trigger desktop notifications. You can change this preference to include all messages sent to channels that you're a member of, or nothing at all:

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Select Notifications.
  4. Under Desktop notifications, choose your notification triggers.

All members automatically receive notifications when someone replies to a thread that they're following. Untick the box to stop getting those notifications.

Note: By default, Slack for Windows notifications are set to deliver via Slack for Windows 7, and via the Windows Action Centre for Windows 10.

Notification sound and appearance

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Select Notifications.
  4. Under Sound & appearance, choose how notifications look, sound and behave.

Tip: Click your workspace name, then select Do not disturb to pause notifications for a period of time.


Badge notifications on the Slack icon

When you have an unread notification, you’ll see a badge in the top right corner of the Slack desktop app icon.

Default badge notifications

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

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

If you like, you can remove badges from the Slack app icon by following the steps below.


Set your badge notification preference

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Select Notifications.
  4. Under Sound & appearance, tick or untick 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 that you'd like to see badge notifications for.

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

Taskbar

In your taskbar, a red badge means someone sent you a direct message, mentioned you or used one of your keywords. If your taskbar is set to small taskbar buttons, badges on the Slack icon will not be visible.

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

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu. 
  3. Click Notifications
  4. Scroll down to Flash window when a notification is received and select Always.

Tip: Selecting the preference Always will also keep the Slack icon in the taskbar when the app window is closed. 

Notifications area

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

A red badge means a teammate has sent you a direct message, mentioned you or used one of your keywords.

By default, your app is set to keep running in the notifications 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 prevent the app from running in the notifications area when the window is closed:

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Click Advanced.
  4. Below Other Options, untick the box next to Leave app running in notification area when the window is closed.

 

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

Note: Badges, like this one 1, appear in your channel list whenever someone @mentions you or notifies a channel that you’re in.


Channel-specific and group DM notifications

You can set your notification preferences for specific channels and group direct messages. Choose the messages that you’d like to be notified about, or mute conversations to reduce noise.

  1. Open the channel or group DM.
  2. Click   Details in the top right corner.
  3. Click   More, then click Notifications
  4. Choose your notification preferences, and whether you'd like to use different settings for your mobile device.
  5. Click the  close icon on the top right to save and exit.

Note: If you choose to be notified only about @mentions, the box next to Also include @channel and @here will be ticked by default. You can untick this box if channel posting permissions or messaging permissions have not been restricted for your workspace.
