Just found out that some of the idle trigger campaigns that Marketo automatically deactivated need to be reactivated! How do I see a list of everything that has been turned off in the past 6 months? I already deleted the notifications. Also is there a way to mass activate the ones that need reactivating?
You can see this when the notification warns you a week ahead of time.
But what you can do is look at the campaign inspector and download the entire list and check the dates of deactivation. Not everything should be reactivated.
