Each day we send letters via certified mail in order to track the delivery or failed delivery of certain critical documents. However, it appears that the certified mail cost per letter is higher then the cost to send the same material via the private contract carrier (UPS, FedEx, etc.) under currently negoitiated contracts. These contract carriers are able to provide the same level of tracking services. Additionally, with the exception of post office boxes, nearly all addresses where USPS certified mail can be sent are also serviced by the private contract carrier. Therefore, requiring that a contract carrier is used to send mail where possible and cheaper should generate a substantial for my agency and likely other agencies as well.
