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.
You've mentioned you are also having the above secondary issue with not receiving your email notifications for your form.
When I checked your email notification I found you have no sender set which can affect it.
We generally recommend referring to this email notification guide and also making sure you set it up properly and are using either email@example.com or firstname.lastname@example.org as they are the recommended sender addresses.
According to our servers and your email notification you are using "email@example.com" which is not in our bouncelist when you check your email address.
Result: firstname.lastname@example.org is NOT in the bounce list
Also, you may want to refer to this additional guide to prevent bounce-related email issues and also check your junk|spam folder to make sure it didn't end up there.
