By default, every scheduling link follows Global notifications. Override global notifications lets a scheduling link use its own email and SMS settings instead. For example, you can turn off all SMS for a specific scheduling link while the rest of the scheduling link keeps sending them.
Overriding notifications for a scheduling link
Click on the scheduling link where you want to change notifications.
Click on the Settings tab.
Click on the Override global notifications card.
Turn on the Override global notifications switch.
Pick the Email or SMS tab. Both start with the current global settings.
Uncheck the notifications you don't want to send for this link.
Click Save changes.
The choices apply only to this scheduling link. Once a link overrides the global settings, later changes to the global settings no longer affect it.
