If you’re planning to send out business Christmas cards (or, better yet, holiday cards) this year, you’d better get going. By December 17th or so, many business people start taking vacations, meaning they might miss your cards. If you want to make a great impression, get your cards out before the holidays. Try to get them in the mail this week or early next week. There’s nothing worse than spending a small fortune on holiday cards, only to have them arrive after the holidays. You don’t want your cards to show up when people are in a less celebratory mood and less likely to take the time to read your cards.
