What must be done to delete an asset in Marketo?

To successfully delete an asset in Marketo, it is essential to ensure that the asset is not being used elsewhere in the platform. This means that if the asset, such as a campaign, landing page, or email, is referenced by any operational programs, lead records, or other assets, it cannot be deleted. Marketo prevents the deletion of assets that are actively in use to avoid broken links or disrupted workflows, ensuring system integrity and operational continuity.

The other options focus on aspects that do not directly impact the ability to delete an asset. For example, while ensuring an asset is not archived might seem relevant, this does not necessarily prevent deletion. Similarly, clearing activity history and ensuring an asset is referenced do not apply to the deletion process and do not have a direct bearing on whether an asset can be deleted or not. Thus, making sure an asset is not in use is the primary condition for deletion in Marketo.
