Upon checking your form's notification email alert, I found that you have not set the "Sender Name" and "Sender Email" yet. That could be the reason why you are not receiving the submission emails when the form is submitted. Please check the screenshot below:
You should select a "Sender Name" in the email alert. Please be noted that if there is no sender name, the incoming email server will most likely will treat it as spam or simply reject it.
You should also select/add the "Sender E-mail" in your notification as this is required to be added for your notification alert to work.
