I'm very sorry to read that the snake did not make it. I hope the breeder does right by you.
For your next shipment I'd suggest a few things....
1) refuse to allow a DHL shipping - they have a very poor reputation (ALWAYS ask any breeder what company they use)
2) if it's a problem with your driveway, then you'll either need to address this or figure out another way to pick up the snake
3) if the sorting facility for the shipper is near you, you can request the box be held there for you to pick it up....that needs to be part of the shipping instructions from the breeder, agreed to by the shipper and you need to find out exactly what time to be at the receiving facility to get the snake quickly
4) once you see on the website "out on the truck for delivery", grab a book and park yourself where you can see the roadway - I've done it a ton of times myself if I was concerned about a shipper or a new driver on my route
5) watch the weather at both ends and refuse to have a snake shipped to you if a storm is forecast or the weather is iffy, it's best for the snake if you wait and ship at a more stable time of year
When I have a snake coming in, even though I've never had a problem, I post a HUGE note on my front door for FedEx. It says....DO NOT LEAVE PACKAGE AT THE DOOR....RING THE BELL AND KNOCK VERY LOUDLY...THANK YOU
I'm paranoid and don't trust a doorbell (mine is currently not working actually).
