The one doing the reimbursing would be the courier company not the sender as from legal perspective they still have the package as nobody signed it off. Similarly you shouldn't sign a package if it looks clearly damaged on the outside. If you do then getting reimbursement gets harder as the courier company can claim that you broke it after they delivered it. The system is by no means perfect but I like that it dictates very clearly who is responsible for what/when. And as pointed out by Symbiote most companies have a way to give them power of attorney to deliver the package without someone signing it.
