 Metric alerts work in the same way as Issue alerts and can be muted on the **Alerts** details page by clicking the "Mute" button.
 
+## Disabled Alerts
+
+Sentry has disabled duplicate alerts and alerts with no actions. If a noisy alert is sent to a communication channel and receives no engagement for an extended time, Sentry will proactively disable it to reduce unnecessary noise.
+
+Anyone with [alert edit access](/product/accounts/membership/) can re-enable an alert by editing its conditions and re-saving it. Alerts need to pass Sentry’s checks before they can be saved. See [best practices](/product/alerts/best-practices/) for guidance on writing useful alerts.

 ## Notifications
 
 Besides alerts, Sentry sends you notifications about various things like [issue state changes](/product/issues/states-triage/), [release deploys](/product/releases/), and [quota usage](/product/accounts/quotas/). You can fine tune these notifications, as well as your personal alert settings, in **User Settings > Notifications**. Learn more about notifications and adjusting their associated settings in [the full documentation](/product/alerts/notifications/).
