It is not recommended to embed the form in an HTML email. Most email providers does not support script in HTML emails. You might be able to send it but the recipient provider might block it, tag it as a spam or as a malicious email. You will also be having a hard time designing it because there are email provider that doesn't allow external stylesheets. JotForm is using external stylesheets and scripts.
I would recommend you sharing or emailing the form's direct link instead. Here's a guide: https://www.jotform.com/help/303-How-to-Send-a-form-via-email
