Customer Email Settings
A customer has a property Subscribed that when true indicates that they have opted in to receive emails.
A customer who has opted out or unsubscribed will have a subscribed setting of false.
If an email is marked as Service or Transactional, then a customer will still have the email sent to them if they are unsubscribed. Service/Transactional emails are used to send emails to customers based on a transactional interaction the customer has completed.
Emails that are not marked as service/transactional are for bulk marketing (although each e-mail can be customised to be specific to that customer). Bulk emails are not sent out if the customer is unsubscribed.
A customer who has made a complaint/marked emails as spam, has a do not send flag set against them. These customers will not receive emails.
A customer who is deleted will not receive emails.
