Postcards can be a very effective and economical form of marketing. They could be mailed or handed out. The biggest advantage of a postcard is its readability. A postcard with a strong design will always be noticed; but the design is extremely important. The design must be catchy enough to be noticed and the message must be clear enough to be understood very quickly. The design must also be appropriate for the target audience; this will insure the highest possible response. Keep in mind that the design cost is the smallest portion of your mailing campaign, but has the biggest effect on your results. It is unwise to spend large sums on printing, postage and mailing list cost and not get the best possible results because you didn't invest in a quality design.
