Do they mail you a statement every month for apple card?

I've never received a statement in the mail.

You can obtain a statement on your iPhone as described in the "See your payment history" section of How to make Apple Card payments - Apple Support

Or you can use a computer internet browser and log into https://card.apple.com/

You will get a monthly notification that a new statement is available, as well as notifications about upcoming payment transfers, and can then use Wallet app to generate XML data or a PDF-format statement.

No.

However you can download statements from your Wallet app.
