Slack Notifications Setup Guide for Desktop & Mobile

This guide walks you through configuring Slack notifications on both desktop and mobile so you never miss an important message while staying focused. You’ll learn how to adjust notification preferences, set custom keywords, and manage channel-specific alerts across all your devices.

What You’ll Need

• A Slack workspace where you have permission to change your notification settings (most members do).
• The Slack desktop app installed on Windows, macOS, or Linux, or access via a web browser.
• The Slack mobile app installed on iOS or Android, and you must be signed in to the same workspace.
• An internet connection to sync settings across devices.

Step-by-Step

Desktop (Windows, Mac, Linux, or Web)

1. Open Slack and sign in to your workspace. If you’re using the web version, go to your workspace URL (e.g., yourworkspace.slack.com).
2. Access Preferences: Click your profile picture in the top-right corner, then select Preferences from the dropdown menu.
3. Go to Notifications: In the left sidebar of the Preferences window, click Notifications. This is where you control all notification behavior.
4. Set your notification trigger: Under “Notify me about,� choose one of:
   • Direct messages, mentions, and keywords – get notified for DMs, when someone uses @yourname, and when any of your highlighted keywords appear.
   • Direct messages and mentions – only DMs and @mentions.
   • Nothing – turn off all notifications (you can still check manually).
5. Adjust timing: Under “Notification timing,â€� decide when you want to receive notifications. You can choose to be notified immediately or set a schedule (e.g., only during work hours). Slack also offers a “Use my presenceâ€� option that sends notifications only when you’re active.
6. Configure keywords: In the “Highlight wordsâ€� section, add words or phrases (comma-separated) that should trigger notifications even if you’re not mentioned. For example, “urgent, deadline, launch.â€�
7. Channel-specific overrides: Scroll to “Notification overrides for specific channels.� Click Add Channel, select a channel, and choose whether to always notify or mute. This lets you mute a busy channel but still get alerts for important ones.
8. Sound and appearance: Under “Sounds,� enable or disable notification sounds. You can also choose to show a banner or a badge on the taskbar icon.
9. Save changes: Slack usually saves automatically, but check for a “Saveâ€� button if you’re on an older version. Your desktop settings will sync to your mobile app if you’re signed in with the same account.

Mobile (iOS and Android)

1. Open the Slack app on your phone and sign in to your workspace.
2. Go to Settings: Tap your profile picture (bottom-right on iOS, top-left on Android), then tap Settings.
3. Tap Notifications: In the Settings menu, select Notifications.
4. Choose your trigger: Just like desktop, select “Direct messages, mentions, and keywords,� “Direct messages and mentions,� or “Nothing.�
5. Set timing: Under “Notification timing,� choose “Immediately� or set a custom schedule. The “Use my presence� option works on mobile too.
6. Add keywords: Tap “Highlight words� and enter terms that should notify you. These are separate from desktop keywords, so add them again if needed.
7. Channel overrides: Tap “Channel-specific notificationsâ€� to mute or unmute individual channels. This is handy for muting a noisy channel while still getting alerts from your team’s main channel.
8. Push notifications: Ensure your phone’s system settings allow Slack to send notifications. On iOS, go to your phone Settings > Notifications > Slack and enable “Allow Notifications.â€� On Android, go to Settings > Apps > Slack > Notifications and enable them.
9. Test it: Ask a colleague to send you a DM or mention you. If you don’t receive it, check your phone’s Do Not Disturb mode and Slack’s own notification settings.

Common Mistakes

• Forgetting to sync keywords: Keywords set on desktop do not automatically appear on mobile. You must add them separately on each device.
• Muting a channel but expecting DMs to come through: Muting a channel only affects that channel’s messages, not direct messages or mentions. You’ll still get notified for those unless you change the global trigger.
• Ignoring system-level notification settings: If Slack’s settings are correct but you’re not getting alerts, your phone’s OS might be blocking notifications. Check your device settings.
• Setting “Nothingâ€� and wondering why you don’t get alerts: This option completely disables notifications. Choose a different trigger if you want any alerts.
• Not using “Use my presenceâ€�: This feature is useful but can be confusing. It only sends notifications when you’re active, so if you’re away, you won’t get them until you return.

Tips

• Use keywords strategically: Add project names, client names, or urgent words to stay informed without being bombarded.
• Set a schedule for after-hours: If you want to disconnect outside work hours, use the “Notification scheduleâ€� feature to only receive alerts during specific times.
• Mute non-essential channels: Right-click a channel on desktop (or long-press on mobile) and select “Mute channelâ€� to reduce noise.
• Customize sounds: Choose a distinct sound for mentions so you can tell them apart from other notifications.
• Use the “Pause notificationsâ€� feature: When you need deep focus, click the bell icon at the top of Slack and set a pause for 30 minutes, 1 hour, or until tomorrow.

Troubleshooting

You’re not receiving notifications on desktop:

• Check that your notification trigger is not set to “Nothing.â€�
• Ensure Slack is not in “Do Not Disturbâ€� mode (look for a bell with a slash in the top bar).
• On Windows, check that Slack is allowed to show notifications in your system settings (Settings > System > Notifications). On Mac, check System Preferences > Notifications.

You’re not receiving notifications on mobile:

• Verify that Slack’s in-app notifications are enabled and that your phone’s OS allows notifications for Slack.
• Check if your phone is in Do Not Disturb or Silent mode.
• Make sure you’re signed in to the correct workspace on mobile.

Notifications are delayed:

• If you’re using “Use my presence,â€� Slack may delay notifications until you’re active. Try switching to “Immediatelyâ€� to test.
• Check your internet connection; a weak connection can cause delays.

You get notifications for messages you don’t care about:

• Review your highlighted keywords – you might have a common word that triggers too often.
• Mute channels that are not important.

Frequently Asked Questions

Q: Can I set different notification sounds for different channels?
A: Slack doesn’t support per-channel sounds, but you can set a different sound for mentions vs. regular messages.

Q: Will my notification settings sync between desktop and mobile?
A: Some settings sync (like your notification trigger), but keywords and channel overrides are separate per device. You’ll need to set them on each.

Q: How do I mute a channel without leaving it?
A: Right-click the channel name on desktop (or long-press on mobile) and select “Mute channel.â€� You’ll still see messages when you open the channel, but you won’t get notifications.

Q: Can I receive notifications only when I’m mentioned, not for all messages in a channel?
A: Yes, set your trigger to “Direct messages, mentions, and keywordsâ€� or “Direct messages and mentions.â€� This way, you’ll only be notified for DMs and mentions, not every message.

Q: What is “Use my presence� and should I enable it?
A: This feature sends notifications only when Slack detects you’re active on your device. If you’re away, notifications are suppressed. It’s useful for avoiding distractions during breaks, but it can cause you to miss messages if you’re not actively using Slack.

Q: How do I pause all notifications for a meeting?
A: Click the bell icon at the top of Slack (desktop) or in the “You� tab (mobile) and choose a pause duration. You can also schedule a recurring pause for meetings.
