Why Postcards? A postcard delivers information the way people want to get it today. It arrives open and ready to read. The message it contains is always brief because there’s not a lot of space for it. Therefore, a postcard is quick to read and easy to comprehend. It’s hard to ignore a postcard - even if the reader is sorting their mail over a trashcan and discarding everything that looks like advertising. An attractive postcard with an eye-catching benefit statement will be read by almost 100 percent of the people who get it …and anyone else who happens to see it.
