Why am I not receiving my jot form?

Customers are entering orders, at www.samedaydel.net, but I'm not receiving the form in the sddn101@gmail.com

I have checked the webpage you provided and did not find any form, I also checked the email address and did not find in our bounce list either. 

I would suggest you to check this guide about why emails may not be sending: https://www.jotform.com/help/364-Why-I-am-not-Receiving-Email-Notifications 

If the problem still persists, let us know.
