I am either not understanding or having issues with GF and MC matching the preferred format. In MailChimp they have the option for users to select what type of format to receive. I check that box (settings/List name and defaults/allow users to pick...)
When I setup my form I add the Name, address, and preferred format with the same 3 options.
Now when I go to the feed list in Wordpress GF, add it and I see only: Name First, Name Last, Email. Nothing for Preferred format. So I added a List Field to MC with all 3 preferred format. I matched all items.
can anyone help?
