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.
You can not send multiple submissions at the same time, perhaps you are referring to send the submitted data or the email notification to more than one email recipient, you can do it by following this guide : http://www.jotform.com/help/39-Send-Notifications-to-Multiple-Recipients
Hope this helps.
