List Hygiene


According to the U.S. Census Bureau, people in the U.S. move an average of 11.7 times in their lifetime. And, according to the U.S. Bureau of Labor, people change jobs every 2 1/3 years. This means that if you haven’t updated your mailing list lately, there’s a high probability that your direct mail will be undeliverable or reach the wrong recipient. With rising postal costs and shrinking budgets, smart business professionals are seeing the need to clean up and maintain their mailing lists.
