Show Headers/HTML box in e-mail

How can I make the JotForm transfer the header and HTML box into the e-mail that it populates?

Unfortunately you can not show those fields within the email, but a good thing about the email is that you can modify it in many different ways manually.

What that means is that while you can not use the field from the form, you can copy paste that same text to your email and format it with font style and color that you wish to have in your email.

Do let us know however if you have any additional questions and we would be happy to assist with the same.
