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.
Unfortunately, we don't have unlimited submission package. More about different account type you can find on our pricing page.
With our Professional package you can have 100.000 submission/month. However there are other plans beyond Professional plan:
1 million submissions = $500 a month
0.5 million submissions: around $250
Hope this will help. Let us know if you need further assistance.
