no they don't. USPS, FedEx and UPS all offer overnight delivery. They all offer tracking. They all offer second day delivery. They all offer bulk shipping. The only difference is that USPS has exclusive rights to the mailbox on your door.
And that USPS tends to be less expensive for letters.
I have received contracts in the mail, via UPS, via FedEx. I have received packages in the mail, via UPS, via FedEx.
