Here in Germany there are two kinds of whatsitcalled, the kind of postal 
mail where delivery is recorded. The cheaper kind records delivery into 
the recipient's mailbox. It's used most of the time, so obviously there 
are use cases for it. The expensive kind records that the envelope is 
handed to the recipient personally.

My bank sends me lots of utterly mail that I am supposed to read within 
four weeks. If I don't I lose the right to have mistakes fixed. I'm 
sure the bank would like to know when I first had the opportunity to 
read the mail.
