how do I send an email on submission

Hello info4070,

I am not sure if I have understood your question correctly. Do you mean to say that you want to receive notification email after the form is submitted? 

Yes it is possible to achieve your requirement by adding a notification email alert in your form. The following guide should help you how to add email alert in form:  http://www.jotform.com/help/25-Setting-Up-Email-Notifications
