You can disable an alert delivery configuration so that triggered alerts using that configuration are not executed.
When you disable email as a delivery type, 
displays next to Email under Delivery Types. When you disable a BTEQ script or user program, displays next to the configuration name.
Even though a delivery configuration is disabled, you can still configure action sets that use it. When you do so, the disabled components are highlighted in red on the action set configuration screen.
If the Include in Alert Viewer option is selected when configuring an action set, a triggered alert is logged in the alert log and can be viewed in the Alert Viewer portlet, regardless of whether any other delivery configuration is enabled.
