Receipt collection for Adobe Creative Cloud
Cardboard automates the collection of receipts for payments made through Cardboard, so you don't have to collect the receipts yourself.
Receipt collection with email
According to Adobe Community forums, it's possible to use a separate email address for billing by contacting Adobe Support.
Reach out to Adobe Support for assistance and request to use the Cardboard receipt collection email as your billing address.
This will ensure all Adobe billing information is sent to this designated email.
