Submitter Email

HI:

How do I set up the email that the application will be sent to once the submit button is clicked?

Basically, when you create a form in JotForm, it automatically creates an email notification that lets you received the responses of the user on your form. In case you want also to add another Notification Email and also want to add an Autoresponder Email, you can check this guides for more details:
