Avoid sending duplicate emails


We are using a form for a survey, but we know that not everyone will check the box at the bottom of the form to receive an email showing their responses, so we also created an automation to perform the same task.

Is there a way to modify the table to have a check box related to the email response requested in the form and if it is not checked then the automation email is sent, and if it is checked then do not send the automation email.
