Can the person who sends the email receive a copy?

Is there a setting where the user receives a thank you email and their submission?

Hello mandyti,

If I understand your question correctly, you want to send submission email to the person who submitted the form. Is that correct?

Yes it is possible to achieve your requirement. You will have to add a form autoresponder in your form and that should solve your problem. The following guide should help you on how to add an autoresponder :  http://www.jotform.com/help/26-Creating-a-Form-Autoresponder 

Hope this helps.

Do get back to us if you have any questions.

Thank you!
