Confirmations v/s Notifications on Gravity Forms

Confirmation

This is a message from the system to the user (member), when a form is completed and submitted. The member will see this message appear on their screen after submitting the form. 

In this example the Voting Form simply thanks the member for their vote. 

Hover your cursor over the Default Confirmation name and click edit. Here you can create a custom message that will display to members after they submit the form. 

Notification 

This is an email that is sent out when a form is completed and submitted. A notification can go to anyone (Member, President of the Board, Membership Chair, Social chair). You can have multiple Notifications and thus each email can contain information specific to the person receiving it.  In this example the Voting Form sends an email to the clubs admins who are counting the votes for the clubs elections.
