Hi @kahil
You can specify the fields you want to show in the PRO version. Please take a look at this page to learn more about it: https://www.advancedcustomfields.com/resources/acf_form/.
You can also use the acf/save_post hook to send the email. Please take a look at this page (at the bottom of the page): https://www.advancedcustomfields.com/resources/using-acf_form-to-create-a-new-post/.
Hope this helps 🙂
