Recently I heard a joke about postmen leaving aviso instead of delivering post. If you see him leaving aviso, you can legally beat him. You have his signed proof that you weren't home at the time.
In English "advise", alas, not used in the common language in regards to mail, like it is used in Polish (and Czech?).
Collins ...in British English (əˈvaɪzəʊ) - NOUN
"a boat carrying messages; a dispatch-boat"
