The USPS is almost a dinosaur. With so much being done on line now darn near everything is done that way rather than scribble pencil. Bills are paid online, bank transactions, buyable and free holiday cards are used. So most of the possible mail that was sent 50 years ago is accomplished in front of the keyboard and monitor in your pajamas. Email makes it an instant communication if the address is good, and that means only one person has to be correct to get it to the receiver. And hen there ae things for communication for a reason. FR is a perfect example.
There will come a time when all mail or business will be done this way and the USPS will go by the way of the dinosaur.

I remember when the feds suggested a tax on each email to “offset USPS losses.”
