I believe you are referring to this form: http://www.jotformeu.com/form/40554458792363
If that is correct, I see the email notification is not properly configured :
Sender Name :Make sure you assign it to a field from your form where the user enters her name (usually the"Name" field -or similar)
Reply-to Email :Make sure you assign it to a field from your form where the user enters her email address (usually the"Email" field -or similar)
In addition to this, you may white-list our domain names if the issue persists. (We use Amazon SES method for "firstname.lastname@example.org" sender.)
