JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Email services has become strict and the practice of adding form fields or embedding forms to email contents are no longer possible. Or if it's still possible in one email client, it shall not be compatible with the others. So we no longer recommend this practice.
What you can do or what we can recommend is to provide a bit of information on your email body and the link to the page where your form is located. This will prevent your emails from landing into the spam folder of your recipients as well.
Feel free to let us know if you have more questions or concerns.
