A savvy shopper will take the security precaution of using retailer specific email aliases which are deliberately different from the address the bank has on file. If you send the email address as part of the info you may get a decline because the email address does not match.

It may also be a risk to include the shopper’s phone number in the info, because, again, that may be legitimately different from the number the bank has on file (for example giving the delivery address phone number, or a voicemail number).

For the above reasons I would not go beyond the name, billing address and CVV.
