Woocommerce emails sent only to a list of email addresses should also have the option to be sent to a customer
The primary example of this is the failed order email. It's only available for the site admin because Woocommerce says users can still view the failed order in the orders list or from their payment gateway.
Checking the site orders would take too many steps to go through for a user to see and the same could be said for checking their payment gateways.
Emails are much more noticeable and immediate so there should be an option available for this
