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 think with the use of JotForm API, it is possible that you create your own app or system that should be able to accept emails, and then parse the data to send to your form via JotForm. Feel free to explore the API via this page: http://api.jotform.com/docs/#post-forms
