Can an email notification be removed from the form (not required)?

Can an email notification be removed from the form (not required)? I don't want to receive 100s of email notifications when someone registers. I'd prefer to run the reports as needed. I tried to delete the email from the notification, but it wouldn't allow me to save it without an email address.

Thank you for your assistance/feedback.

Delete the email notifications directly, not its recipient. Here's how: How to Delete Notifications/Autoresponder
