Can I change which email my customer get their notifications sent to?

If your customer has more than one confirmed email address on their account, then you can change the email address at which they get their notifications sent to. You can do this by visiting their customer profile on Perkville and clicking on "Manage emails" on the right side of the page. On the next page, click the "Make primary" button next to the email that the customer would like to use for receiving notifications.
