You can temporarily disable an alert or re-enable a disabled alert. If the alert is disabled, the alert condition does not trigger the e-mail notification. You can also enable or disable a particular alert from the Alert [ Alert Name ] window.
To disable or re-enable an alert:
In the Settings App, navigate to Services > Alerts.
Select the alert to disable and click Action > Disable from the Toolbar Menu. To re-enable a disabled alert, click Action > Enable.
