You would like a specific email address to receive invoices or billing-related emails.
For personal accounts, invoices can only be sent to the main email address listed for the account. You can change the email from your Account Settings, but this change would take effect on the entire account, not just for billing e-mails.

You can check who the Admins are by navigating to the Team view on Heroku Dashboard and going to the Access tab.
