Email Auto-responder: Email is not sending to selected email address.

people who fill out this form are not getting the notification.  any idea why?

I have tested your form and checked the email log for the email address I selected in the field "Your Email *", I can see the email is being sent properly: 

You may also check your email history by following this guide: How-to-View-All-Your-Form-Email-History

Also, if you're still not getting emails, please ask your email provider to white-list our IP addresses, maybe there is some security that does not allow the intended email addresses to receive the email. 

Here you will find our info to white-list: Whitelisting-JotMails-IP-Addresses

Hope this helps.
