How do I get my submissions sent to my email?

I cannot find a way to have my submitted filled out forms sent to my email, so I am notified of a membership and I can approve their application. 

An email  notification is added by default to your form when it's created, the default sender is the address you have configured on your JotForm profile, but that can be changed. 

Please check the following guides that will help you doing so:

I hope this helps.
