Can I send a user an automated email when they fill out a form?

Hi,

Thank you for contacting us.

You can create an Autoresponder, then your submitter will receive an email once he/she submits the form, find the steps to do it on this guide : http://www.jotform.com/help/26-Creating-a-Form-Autoresponder 

Hope this helps.

Feel free to contact us if you need more help, we will be glad to assist you.
