Thanks.

I have tried this changed back and forth between 2 different email addresses and neither one gets the email of the jotform but I do get the change email address notifications. ??

If I understood you correctly you want to change Email address on which you are getting submissions when user submits your form.

You can do that inside of Email Notification by changing Recipient Email address.

Inside of this guide you can find out how to set Email Notification.
