If I recall correctly, I believe it has been advised that the email in question (presuming recipient had advised they want email and have added domain to safe sender list) would need to be forwarded to ClickDimensions for processing. If per chance a new email was provided, then the only action needed would be to update to allow bulk email and make sure there is no unsubscribe record (delete if needed).
I would like to automate this, and wonder if we could send this information to ClickDimensions via email.
