I have created two new forms and have not received the noticifations for the submissions that were sent since to my email?

I checked your new forms, one has 3 submissions, another one doesn't have any.

For this one that has submissions, there is no email associated:

Please try to create email notifier and see how that will work.

I checked your email where all your submissions are going to, and everything seems fine.

Hope it helps.
