The most important part of a postcard mailing is to create a sense of scarcity and urgency. Without that, you’ve got nothing. Creating a great postcard requires that you somehow limit it.
One way to limit your postcard is to focus on a specific niche. This is a great option, but you have some other choices as well. You can also limit it by a time or date. If I receive your postcard for a free system analysis and my computers are going haywire, I’m more likely to pick up the phone if I know that only the first 25 respondents are going to receive the free analysis.
If you are having trouble with your postcards, you’ll want to talk to a professional. This will usually be a copywriter or someone who has retired from a large advertising agency and specialized in direct mail. They can be great resources.
