If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Unfortunately, it is not recommended to embed the form in an HTML email. The reason why is because our embed codes contains scripts that are not allowed in most email providers. There is a possibility that your email will be blocked or tagged as suspicious. I would suggest you to share the form's link instead. Here's a guide: How-to-send-a-form-via-email
An alternative would be creating a fillable PDF form. This fillable PDF form is a PDF file that you can attach to your email message. Please go to this link: https://www.jotform.com/fillable-pdf-form-creator/.
Hope that helps. Thank you.
