" When someone dies, it’s good to mail a note. Don’t send an e-mail. You have to send a card. Everyone should have cards and stamps kicking around. I have some very simple stationery, just nice card stock with my name at the top. When the news is happy, e-mail is fine. You can e-mail congratulations about babies, weddings, anything. But when it’s not? If it’s a death or other bad news, you have to be more formal. "
