If you are running a multivendor eCommerce site or you want to send the emails to the product author. Well, you can do this using this plugin (Pro version only) as well. Just follow steps below-
First, open the CF7 edit page of the form that you are using for the Quote Button, and add the hidden dynamic field with our post author email shortcode ( gqb_post_author_email ). You will see custom a button for that on top of the form page. Just do it as it is shown in the screenshots below.
After that go to the Mail tab and change the To field using the new dynamic hidden field id. That’s it.
