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.
If what you mean by sending email to attendee is that sending an email automatically to the form user after making a submission, you can do that by creating an autoresponder email in your form. You can refer to this user guide for the step by step reference: https://www.jotform.com/help/26-Creating-a-Form-Autoresponder
Feel free to let us know if you have questions.
