If I'm understanding your concern correctly, you want the form to be embedded in the body content of the email so upon receipt of the receiver of the email he can fill it up there. If this is correct, unfortunately it is not possible.
Most email clients no longer allow this practice as they believe it is prone to security issues. The closest solution that you can have on this is to create a fillable PDF version of your form and attach it to the email. This guide will teach you how to create the said fillable PDF of your form: https://www.jotform.com/help/212-How-to-create-a-PDF-form
