email confirmation automatically

I am not quite sure if I understand your concern correctly. If you would like to automatically receive an email when the form is submitted, then that is possible by setting up your email alerts.

If you want to receive it in your own address or specific ones, then you can setup an email notification. Here's a guide that you can follow: https://www.jotform.com/help/25-Setting-Up-Email-Notifications 

If you want the user to receive an email based on the email field you have in your form, then that is possible if you'll setup an autoresponder. Here's a guide that you can refer to: https://www.jotform.com/help/26-Creating-a-Form-Autoresponder
