When a contact is unconfirmed it means that they have opted into MBR CRM but has not confirmed their email address via the double confirmation link.
Unconfirmed contacts can receive marketing depending on your level of compliance.
Contacts marked as Weekly will be able to receive marketing at most once per week.
Contacts marked as Monthly will be able to receive marketing at most once per month.
Unsubscribed contacts cannot receive marketing.
Contacts marked as spam cannot receive marketing. You must manually mark a contact as spam.
A contact is marked as complained if the contact marks the email as SPAM in their email client. Currently, this is only supported if you use the AWS integration to send email.
