How do I integrate a WP Form which includes a name/email field as part of a checkout for a purchase into my Convertkit email list? When I try to do this it asks for my Convertkit Form. Do I need to create a seperate "dummy" Convertkit form to link it to? Will my buyer be asked 2x to enter their name/email (once on the WP form and once on the Convertkit form? How do I do this? My convertkit is already connected to my WP website. Thanks
