You are consulting with a client that initially enters new customers into an eCommerce system that is not integrated with Microsoft Dynamics 365. The client wants to ingest those new customers into Microsoft Dynamics 365 Customer Insights and then create new Contact records in Dynamics 365 Marketing using the "Export Segments to Dynamics 365 Marketing" feature. They do not plan for a direct integration between the eCommerce system and Dynamics 365 Marketing. What advice should you give to your client? 

 Contact records need to be created in Dynamics 365 Marketing in addition to exporting Customer Insights segments. 

Both Outbound and Real-time segment exports from Customer Insights to Dynamics 365 Marketing will create new contact records. 

Only the Real-time connection between Customer Insights and Dynamics 365 Marketing will create new contact records. 

The Dynamics 365 Customer Card Add-in will enable new contact records to appear in Dynamics 365 Marketing via the Export.
