What must be done for an edited asset to become usable?

In Marketo Engage, once an asset has been edited, it often requires a re-approval step before it becomes usable again. This process ensures that the modifications are reviewed and validated according to the organization's standards and compliance requirements. Re-approving an asset is crucial, especially in environments where content management and version control are vital for maintaining brand consistency and accuracy in messaging.

The other choices do not align with typical practices in Marketo. For example, while publishing is an important step, it usually follows re-approval if the asset has undergone significant changes. Automatic usability after editing would imply a lack of oversight, which is not conducive to maintaining quality. Lastly, deleting and recreating an asset is unnecessary and inefficient when re-approval can reconfirm the asset's validity after edits.
