The new MArketing Field propeties are great, allowing us to easily distinguish between different types through dropdown selct and multi-select boxes.
Having date properties would be a game changer however. Main use case for myself would be adding an "unpublish date". A date field after which you no longer need the email. This would allow us to creat views in Email page and unpublish on a regular basis.
Even better being able to use Marketing email properties in workflows would allow us to automate our email hygiene procedures.
