Hi,

I checked your form, http://form.jotformpro.com/form/51372598584973, and noticed that you are using a custom sender e-mail, the same as your other forms, from your other threads. We have been informed by our developers that the issue regarding email notifications with custom sender e-mail is now fixed. -  http://www.jotform.com/answers/659226. 

If the issue still continues on your end, please change the Email address in Sender field to noreply@jotform.com or noreply@formresponse.com. Or use the other method: How to use Mandrill to Send Emails From Your Own Email Address. 

Do let us know of you need further assistance.

Regards.
