Mail Delivery Companies used by LetterStream

All of the mail send through us is handed over to the USPS for delivery, except for our FedEx Business options (which are products that a Business account can utilize after a brief qualification process), which is given to FedEx.

Additionally, any services that don't produce physical mail (such as our address cleanup services CASS and NCOA) are not given to any mail processing companies, since delivery is not applicable in that instance.
