Use Case I: Need to fail the Delivery executed on an adhoc basis by the user in preparation stage if some mandatory URLs are accidentally deleted before sending or missed to get reviewed while proofing the content. For example Opt Out link, Mirror Page link, subscribe link or any other links. Something similar to what we have for Check subject line control rule. Note* - Check unsubscription link (urlOptout) OOB control rule is not failing the delivery when an opt out link is not present. It just writes the warning in the log.
Use Case - II: Need to fail the Delivery executed on an adhoc basis by the user in preparation stage if the user has not named the Delivery Label using proper naming convention.
