You left out the biggest problem with the Post Office - it is often closed when you have the free time to go there.

I've been using private mailbox services for nearly 2 decades now and they have it all over the USPS PO. 24-hour package pickup. They throw away junkmail for you. They will text you when you have a package. They can accept shipments from any carrier - USPS, UPS, FedEx, etc.

They will forward mail in batches to another address, say you moved out of state but still want your old address to keep working for another 6 months. If you file a change-of-address form with the USPS they sell that info to anybody with a couple of dollars (like your college alumni association and any other charity you ever donated to). Some will even open your mail for you, scan it and email it to you.

Plus, the address looks like an apartment but it is not your home address - so telling someone where to mail you doesn't also tell them where you live.
