Opting them out from the one-to-one email subscription type would indeed be the safest option. You could simplify it however:
The enrollment criteria check whether a contact does have a certain email domain (this could also be referenced via a list, yes) and whether the contact is either opted in or does not have an opt-status (because why enroll contact that are already opted out).
Recently, a feature was added in workflows that lets you unenroll contacts from a contact-based workflow – but that is useless here as a contact would have to be enrolled to begin with.
Hope this helps!
