Is there any way to inject static html into the email sent when a user clicks submit by adding a hidden field to the form? I have seen other ways on the forums by using a custom function to insert an image as an attachment, but what I would like to do is append the html to the bottom of the email in the same html. Basically, if the html is on the form in a hidden field, insert it into the same location as it was on the form in the email.
