Am now using this great app with gusto, however I think that if someone unsubscribes or even marks the email as spam, i.e. they get onto the rejection list locally then emails are not sent for anything else, such as password reminder, notifications and third party apps.
I appreciate that if the email is on mandrill's rejection list nothing will go, but sure these other emails should be sent even if the email is only the local rejection list?
Really we should only see admin newsletter emails blocked and not any other email, ideally this should also apply to the Mandrill held list.
