Your form has by default an email notification when you create it; however, you can add an email notification by following the steps on our guide about Setting-Up-Email-Notifications.
Maybe the email address you're using is in our bounce list, this guide will help you to find the email address currently used on email notifications: How-to-Find-and-Change-the-Email-Address-Used-for-Notification-Email
Once you get it, you may check if it is in our bounce list and remove it, since an email in our bounce list is one of the reasons why emails are not sent, here is the guide that will help you with that: How-to-Remove-Your-Email-Address-from-Bounce-List
Hope this helps.
