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.
I have tested your form and checked the email log for the email address I selected in the field "Your Email *", I can see the email is being sent properly:
You may also check your email history by following this guide: How-to-View-All-Your-Form-Email-History
Also, if you're still not getting emails, please ask your email provider to white-list our IP addresses, maybe there is some security that does not allow the intended email addresses to receive the email.
Here you will find our info to white-list: Whitelisting-JotMails-IP-Addresses
Hope this helps.
