I've just set a smart campaign restriction to abort sent if qualified leads exceed 50,000 sends. However, this is done without notified anyone to review the smart list or adjust the campaign. Is there any way to trigger an alert if a smart campaign is aborted?
There is a system notification for campaign failures: Notification Types - Marketo Docs - Product Docs. From there you can subscribe to that notification type and receive an email alert in addition to the system notification.
