Postcards may be used for many different applications and are very effective. Postcards are wonderful for direct mail campaigns. With a postcard your prospect does not have to open an envelope. Before they even have a chance to think about throwing it away they have already seen your advertisement. This is a great way to direct people to your web site or to advertise sales and specials. Postcards are also great to mail as a follow up to a sale. Once you have a customer you do not want to lose the customer by them forgetting about you. With postcards you can maintain contact with your customers for a low cost and very little effort.
