Issue
Customer wants to know if they can add their primary/secondary email to the invoice email list for their heroku account
Resolution
You can navigate to the Account settings page but this change would take effect on the entire account, not just for billing e-mails.
If you’re looking to add any secondary/additional email, then that is not possible. However, if you’re looking to replace them, then you can simply edit the email and remove the existing email, then add the new one.
