This is largely an issue with the email functionality of the server the site is hosted on, and the email addresses the form is using for TO and FROM, and in your case BCC (some mail transfer agents have a problem with BCC or multiple BCC or the FROM address being a different domain than where the mail originates.)
One thing that works for many people is to use an SMTP plugin, for more reliable email delivery. Please install and configure one of the following plugins, and test your form again.
Also, we have some additional explanation and troubleshooting steps here:
If the email is not being sent, it's because it's not being sent by the host where website is hosted. Gravity Forms hands off the notification immediately to wp_mail() and it in turn uses whatever mail transfer agent is available on the host (unless you are using an SMTP plugin.)
