PostGrid Glossary List Cleaning

List Cleaning

List cleaning is the process of reviewing and updating a mailing list to remove or correct inaccurate, outdated, or duplicated addresses. This practice is essential for maintaining the effectiveness of direct mail campaigns, as it helps ensure that mail reaches the intended recipients, reduces the amount of undelivered mail, and minimizes unnecessary costs. Regular list cleaning also improves data accuracy and enhances the overall ROI of marketing efforts.
