10 Ways to Fix Slack Notifications Not Working on Mac/Windows

On a global scale, the workplace culture has significantly transformed since the onset of the COVID-19 pandemic, with a notable increase in remote work compared to traditional office settings. For those working remotely, diligent attention to notifications has become crucial for effectively managing tasks and meeting deadlines.

Missing a critical SMS, especially one received on a Monday morning, can be unsettling, particularly if the lack of awareness resulted in not receiving the notification. In such scenarios, the messaging platform “Slack” proves invaluable.

If you are encountering difficulties with Slack notifications on your Windows or Mac desktop, rest assured, as we have experienced and addressed this issue ourselves. In this guide, we will not only shed light on the problem but also offer practical solutions to rectify Slack notification issues, ensuring you stay informed and well-equipped to manage your workflow seamlessly.

Why are Slack Notifications Not Working?

Slack stands out as a premier means of communication among individuals, offering diverse advantages for both remote workers and those in office environments. It ensures swift awareness of messages from supervisors or other teams, allowing for prompt responses to inquiries. However, the effectiveness of Slack notifications may occasionally require adjustment.

Some users encounter issues where Slack notifications are not received despite being enabled. To fully harness the potential of this communication tool, it is imperative to ensure that notifications are operating seamlessly. Failing to do so may result in overlooking urgent meetings or important messages, giving the impression that the communication was never received.

Several factors could contribute to this problem, with one prominent cause being device settings. Even minor alterations, such as setting your device to “Do Not Disturb,” can impede Slack notifications. Let’s explore some potential reasons for Slack notification issues.

Desktop Notifications are Disabled

If Slack notifications are disabled in the application or device settings, you will not receive them. It is crucial to check and confirm that the notification settings are turned on to ensure proper receipt of notifications.

Focus Assistance

Enabling Focus Assist mode to concentrate on your task will result in not receiving Slack notifications. This mode deactivates all notifications on your device while in use.

Paused Notifications

It is conceivable that you temporarily halted Slack alerts by pausing them. Consequently, it is essential to check for any paused notifications and address the issue if present.
