Given the recent EDH integration process there is an issue with EDH donors that choose to opt out of future correspondence and emails (identified using a UDF - EDH Communication Preferences) but unfortunately the system defined field under Person (Opt Out of all mass emails) is not updated and there is no option for mass update or import to update EDH opt outs to all mass email opt outs apart from manually changing their accounts. It would be fantastic to have some method of automatically checking the Persona field Opt Out settings from EDH integration.
