Deletes an email newsletter draft in KlickTipp, along with its email, its audience conditions and its system tags. Only drafts can be deleted: a newsletter that is scheduled, on its way out or already sent is refused, and so is one that other entities still refer to -- the refusal names them. This cannot be undone, so only call it for a newsletter the user has explicitly asked to delete.
