It’s harder not to read an interesting postcard than to avoid reading it. An eye candy design and a compelling offer can catch your eye and it’s difficult not to read it. Nothing else in your mailbox can capture that much attention except a large check from the government. Most junk letters never get opened unless they looks official. People don’t have the time or care to read. Flyers can also have too much to read and they instantly get tossed. On the other hand, postcards are noticed and read because the message requires just a second to decide if you’re interested or not. They don’t have to be unfolded and they don’t waste time with a lot of words.
