Make it possible to select a different type of emailaddress (emailadress1, emailadress2, emailadress from secretary, etc.) based on conditions. And maybe even better make it possible to send an email to a contact in a lookupfield. (fe. secretary is as well a contact in the system and available at the contact)

Now in Real time marketing it is only possible to send an email to the same emailadress every time. In outbound marketing it was already possible to customize (but not based on conditions).

Aware that consent should also be created for the other emailadresses.
