What Does “Slack Notifications Not Working” Mean?

When Slack notifications are not working, it means you are not receiving alerts for new messages, mentions, or calls, even though messages are arriving in your channels or direct messages. This is a notification delivery issue, not a messaging or account problem.

Why Slack Notifications Stop Working

Notification settings may be turned off or customized incorrectly within Slack.

Do Not Disturb (DND) mode may be enabled, silencing alerts during certain hours.

Operating system notification permissions may be disabled for Slack.

Focus modes, battery optimization, or background app restrictions can block notifications.

Network delays or syncing issues can also interrupt notifications in Slack.

What This Issue Does Not Mean

It does not mean your messages are blocked.

It does not mean your account is deactivated or restricted.

It does not usually indicate a server outage unless many users are affected.

How to Restore Slack Notifications

Check Slack notification preferences and make sure alerts are enabled for messages and mentions.

Confirm that Do Not Disturb is turned off.

Verify system-level notification permissions for Slack on your device.

Disable battery-saving or focus modes that may restrict background notifications.

Restart or update the Slack app to refresh notification services.

When to Be Concerned

You should investigate further if:

Notifications fail across all devices
Mentions and direct messages are silent
Other users receive notifications normally

This may indicate device-level restrictions or account-specific settings.

Final Takeaway

“Slack notifications not working” usually means alerts are being blocked by app settings, system permissions, or focus modes. Once notification settings are corrected, alerts typically resume immediately.
