What does the subscription status mean?
Subscription status can be used to identify the current stand of contacts to decide if it's the right time to send them email campaigns and also to know if they want to receive email campaigns. There are three types:
Marketing: These contacts are ready to receive email campaigns and they've shown their interest in receiving email campaigns or expressed explicit consent to receive campaigns.
Non-marketing: These customers have not subscribed to receive email campaigns.
Unsubscribed: These contacts are no longer interested in receiving email campaigns.
