At the moment consent is automatically updated and solicit codes added when someone opts out of emails, however, the consent statement is not updated if they request to be opted in again. We send them the link to opt in but there is no way of automatically recording they have been sent the opt in email and their response is not record either. This means that when our auditors see we have been sending emails to some one who has previously opted out, there is no record of them opting back in again.
