Export data to acymailing

i can export my cvs in Gmail. The name and the first name is going in the field of contact very well. But i want to export, the must important, the Email. I change the type of field for text, before it's was email and it,s not working well.

For understand the format of cvs for export in Gmail, i export CVS file in the Gmail and look how it's done. He has a lot of ,,,,,, when nothing in a field for Gmail. How can i do that in Flexicontent, if it,s possible.

See my attachment.
