Thank you notes seem to be one of the few things people still expect to receive the old-fashioned way: handwritten and in their mailboxes. But for those who are eager to embrace a more modern etiquette, there’s a dandy little app called Postography that allows you to send personalized postcards right from your phone. In other words, snap a cute shot on your honeymoon, add a note of thanks and your signature, and be done (postage included!). Oh, and every 20 sent plants a tree. Free and green? We like it!
