What is the proper way to address outer envelopes?
Following proper etiquette includes spelling out as much as possible. This includes street names, titles (except for Mr. and Mrs.), and even street numbers when there is room. It is not considered proper to indicate “and Family” or “and Guest” on the outer envelope. For the list you prepare for me, you do not have to spell out “Street, Avenue, Drive, Post Office, or State Names. Please indicate an Apartment Number by writing out “Apt.”, “Unit”, or “Suite” and not just using the number sign.
