Is Postcard & Direct Mail Marketing Dead?
Some designers and marketing companies believe that using postcards in a direct mail marketing campaign is dead. That’s because they don’t understand your company’s audience.
The majority of professionals know postcards are still a viable marketing tool when used correctly. Tylenol, Google, and Burger King (all completely different industries) still use postcard design in their marketing strategy in two important ways. One is to obtain new customers by offering a coupon or free sample and two is to promote their new products, events, or services. They send relevant information to a very geo-targeted audience, which is why they’re so successful with their campaigns.
Postcards are comparatively inexpensive, and they have a much higher read-through rate than letter mail since the receiver doesn’t have to open an envelope to be drawn in. That being said, when people see your postcards in the mail, you only have a few seconds to convince them to read it through before it ends up in the trash.
