Once an automation is live, you must pause it to make any changes to your enrollment rule or goals.
Editing your Entry Rule
If you edit your enrollment rule after an automation has been started, this will not have any effect on the contacts currently in your automation. Once you restart your automation, only contacts who meet the new enrollment rule will be entered into the automation.
Editing, Adding, or Removing Goals
Editing a goal after an automation has started will not affect contacts who have already met that goal. Moving forward, it will only remove contacts who meet the updated goal.
Adding a new goal does not affect the contacts who have already met other goals. Once you restart an automation with a new goal, the next time that automation processes all of the contacts who meet the new goal will be removed.
Removing a goal will not affect contacts who have already met that goal. It will simply stop removing contacts in the automation.
