Gravity Forms notifications can be set up to control where emails get sent after forms are submitted. They can go to you, your customers or multiple people. Here’s a link to the documentation on their site: https://docs.gravityforms.com/configuring-notifications-in-gravity-forms/.
We also have a Gravity Forms basics tutorial on the support site here: https://support.mydirigible.com/documents/using-wordpress/site-editing/gravity-forms-basics/
