When customizing the yMarketing email action I have to deal with the class CL_CUAN_MKT_EXEC_EXECUTE_EMAIL. In this process, I need to access the ID of the campaign which starts the action. To be more specific, I need the ID when the personalization of the email is handled which happens within the personalize() method.

I couldn't find any information about the executing campaign ID, just about the content ID of the email. Does anyone know how to access the campaign ID?
Kind regards.
