In the unsubscribe export file on Mailchimp, it lists the email campaign that prompted the user to unsubscribe under the 'UNSUB[underscore]CAMPAIGN[underscore]TITLE' field. Unfortunately this campaign field is currently not information available within the unsubscribe connector API. Neither is UNSUB[underscore]TIME. it would be good to be able to add this information to RE through Omatic Cloud as it is vital additional context on unsubscribes.
