Postcard Design When designing a postcard, it’s a good idea to pay close attention to detail. The design details play a critical part in delivering your marketing message to prospective customers. Following are some design tips that can help make an impact: Images should be clean, identifiable and noticeable from a distance. Designs should be simple but eye-catching. Don’t overload or clutter the postcard with too much information. Emphasize the postcard headline. Be persuasive to your customers and give reasons how your business or service can benefit them. Use different shapes or sizes of cards to attract attention. Another tip to consider is online design templates that are available for free and can save a lot of time. Many printing companies offer this service on their websites.
