CPC?, also possible to initiate without in combination with ads spend? -other ways to get permission to contact user via messanger or notification system in Facebook You should be an expert and know all these features above so you can answer my question without needing to pretend and reading developers guide during our conversation (that I have done myself and will notice :-D) You should be fluent in English.
