Sending email without creating contact?

Hi

I was wondering if it was possible to create a trigger based campaign without creating the contact data, facets, …

I want to avoid creating those for a specific interaction type.

I tried to use the functionality of Anonymous id_origin but it doesn’t seem to help me doing it.

By testing the function module CUAN_CE_INTERACTIONS_POST_FLAT

And filled the fields:

COMM_MEDIUM : ZDMW

IA_TYPE : ZBACK_IN_STOCK

TIMESTAMP: 20.171.030.110.250,0000000

IS_ANONYMOUS : X

SMTP_ADDR: cdurieux@distriplus.be

EMAIL_OPTIN : Y

My interaction is created but without SMTP_ADDR and without EMAIL_OPTIN (became blanco due to anonymous I suppose)

I have no new contact and no new facet but also no email sent …

Do I need to create all those contacts and facets and cleaned them? Is that the only way?

Did anyone experience that?

PS: I am on the on-prem version 1702

Regards

Catherine
