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 presume you are using the "Forward" button in the submissions page?
Please note that for "Free" accounts, you are limited to send a total of 20 emails/hour, this limit covers the "Share a form via Email", "Reply", "Forward" and "Test Emails" button, or any email that will come from the form builder.
"Share Form"=>"Email" button.
"Reply" and "Forward" buttons
"Test Emails" button.
You can also use your own email client and just forward the notification you received to your users.
