Years ago, went through a stretch where in November every package routed through USPS was being marked out for delivery and then by 7:30pm was being marked 'undeliverable no such address'.

When USPS ticked off that box, Amazon would immediately send me an email blaming me for having the wrong address on my packages and telling me they'd be returned to sender. I'd have to call Amazon support and confirm I had given them the correct address each time. They'd tell me they'd try to call the post office the next day to find out what was going on but that if I waited a day or two it might just show up. I'd beg that they stop routing my stuff through USPS and they said there was no way to pick a preferred courier in their system. It may or may not show up but I'd have lost all tracking on the item at that point so no way to know if it was out for delivery or not.

I filed a complaint on the USPS website and the local postmaster called me back a couple of days later, trying to explain they were understaffed and if it was too dark to deliver the mail (??) or a package got on the wrong truck there wasn't an option in their scanning tool for that so they were just picking undeliverable due to wrong address and trying to get me to be understanding about it. I told her I'd be more understanding if they weren't choosing an option that blamed me for the package being late and triggering all this BS with Amazon, and also the too dark for mail thing meant we weren't getting our mail either, which also wasn't okay.

They found my packages and dropped them at my house at 7am the next morning, and they changed our courier route so now our neighborhood's mail is delivered earlier in the day (1-2pm instead of 5-6pm). They put a Managed Service Point sticker with a barcode in the lid of my mailbox that the courier had to scan every day as part of tracking their route progress.

It's been so much better since then. I still get the occasional "delivery delayed" message but they usually update the tracking in the morning that it's out for delivery. I actually get delivery delayed more from Amazon's own internal delivery fleet than I do USPS these days.
