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.
Free account type provides 100 submissions(HTTP) per month. I think, it will provide what you need; but you need to be careful about not to use secure(HTTPS protocol) submission. Because you have only 10 for that type submission on free account.
To disable it,
Leave the "Secure form" check box unchecked, when you embedding your form and make sure your form link uses HTTP.
If you encounter any error, please feel free to contact us.
