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 directed to 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.

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


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

Only @mentions, direct messages and keywords will trigger a desktop notification by default. You can change this preference to include all messages sent to channels 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 Notify me about, choose which activity you want Slack to notify you of.

Tip: tick the box next to Notify me about replies to threads I’m following to receive notifications when someone posts a new message to a thread you’re following.

Note: using Slack for Windows? By default, 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 should look, sound and behave.

Tip: click the  bell icon next to your workspace name and choose how long you'd like to snooze notifications.


Badge notifications on the Slack icon

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

Mac

Windows

Linux

Default badge notifications

By default, any 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 want, 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.
  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 you want to see badge notifications for.

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

Your app is set to keep running in the notification area even when the window is closed by default. 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 Advanced.
  3. Under Other options, untick 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 has 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.
  3. Under Sound & appearance, tick 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 unticked.

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.

  2. Select Preferences from the menu, then click Advanced.
  3. Under Other options, untick the box next to Leave app running in notification area when the window is closed.

Note: badges, like this one 1, appear in your channel list whenever someone @mentions you or notifies a channel you’re in — this only includes @here if you’re active on Slack at the time the message is sent.


Channel-specific & group DM notifications

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

  1. Open the channel or group DM.
  2. Click the  cog icon to open the Channel or Conversation settings menu.
  3. Select Notification preferences.
  4. Choose your notification preferences and whether you’d like to use different settings for mobile devices.
  5. Click the  close icon on the top right to save and exit.

Note: If you choose to be notified about just @mentions, the box next to Also include @channel and @here will be ticked by default. You can untick this box unless channel posting permissions or messaging permissions have been restricted.


Email notifications

By default, you'll get email notifications if you're not active in Slack and someone mentions or sends you a direct message. Here's how to change your preference:

  1. From your desktop, click your workspace name in the top left.
  2. Select Preferences from the menu.
  3. Select Notifications.
  4. Under When I’m not active on desktop, tick or untick Send me email notifications. If ticked, click change to choose how often notifications are delivered.
