Which of your form is not sending submission emails?
I did check your last edited from and I found that you have two notification email alert there. In one of the email alert you have not set the "Sender Name" and in the other email alert you have not set the "Sender Email". Please check the screenshots below:
In your "Notification" email alert, please select the "Sender Name". If you do not set the sender name, the incoming sever can mark it as spam or simply reject it.
In "Notification 2" email alert, you should select/add the "Sender E-mail" in your notification as this is required to be added for your notification alert to work.
You can select "firstname.lastname@example.org", "email@example.com" or you can also setup a custom "Sender E-mail" option. This guide should help you:
Hope this helps.
