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.
The email address used for submission notification is not in our bounce list, have you check your spam folder? I can see your email notification is not properly setup:
Sender Name :Make sure you assign it to a field from your form where the user enters her name (usually the "Name" field -or similar).
In addition to this, you may white-list our domain names, if the issue continues, as we use Amazon SES method for "firstname.lastname@example.org" sender.
