When migrating from one email marketing tool to another, it's common practice to import your entire list, both subscribed and unsubscribed. This preserves unsubscribe history and ensures you don't inadvertently add an unsubscribed email to your list through automation (like syncing a user group into Campaign) or other actions.
One implementation idea:
during import from CSV, offer "Force Unsubscribe" option so all contact imported get the status.
This is typically a one-time event when migrating, so it may also be solved with a custom module using existing service methods.
