What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
My understanding is that you want to send a confirmation email when someone completed your form.
If yes, then you need to create an Autoresponder Email alert. The Autoresponder is the email that your users will received upon completing the form. Here's a guide: https://www.jotform.com/help/26-Setting-Up-an-Autoresponder-Email.
If you want to receive an email copy of the submission, then you need to set an Email Notification alert. Here's a guide: https://www.jotform.com/help/25-Setting-Up-Email-Notifications.
Hope this helps. If not, please let us know so that we can further assist you. Thank you.
