If email is too informal but you're too busy to make and send a holiday card on your own, Gmail is running a fun promotion allowing you to send one snazzy holiday postcard on their dime. Just head to the Happy holidays from Gmail page, enter your message, recipient's information, and pick the envelope style you want. The first postcard choice is a straight Gmail advertisement, but they're all pretty nice looking (we particularly like the snowflake twins above). [Happy holidays from Gmail]
