The ideal postcard is visually appealing, with a direct, concise message. Step 1: Plan the main purpose of your correspondence. Keep it brief and to the point. Step 2: Use catchy phrasing or specialized text to draw and keep the reader’s attention. Write with clarity and creativity. Step 3: Remember that a postcard can be viewed by anyone at any time. It is inappropriate to use this medium of communication to announce or share sensitive or confidential information. Note: At the end of this chapter is a checklist to use when you write a postcard.
