According to the IRS: Payments made with a credit card or payment card and certain other types of payments, including third-party network transactions, must be reported on Form 1099-K by the payment settlement entity under section 6050W and are not subject to reporting on Form 1099-NEC [and Form 1099-MISC].
While you could email the 1099-NEC, it contains social security numbers so sending by regular mail would be more secure.
