In edrone we recognize 3 subscription statuses:
Subscribed (mark in imports as a 1) - these are users who have agreed to receive marketing messages.
Unknown (mark in import as blank/no value) - these are users who have entered an email address (e.g. by creating an account or making a purchase), but did not agree to receive marketing messages. You can send transactional messages from automation scenarios to customers with this status.
Unsubscribed (mark in imports as a 0) - to customers with this status we cannot and will not send any messages, because they have unsubscribed from the mailing. This change is reversible - the customer can subscribe to the newsletter again.
