How to build and validate address lists for direct mail marketing
By Ryan Cox on December 4, 2025
Looking to build a direct mail marketing campaign? You’ve come to the right spot. Before you can send marketing mail like a pro, you’ll need to build a list of verified addresses. Otherwise, frequent misdeliveries and costly redeliveries can take the wind right out of your campaign’s sails. On top of that, a bad address list could lead you to miss out on mind-blowing postal discounts. 😱Don’t let bad addresses capsize your campaign. With a US Master Address List of over 210 million verified addresses—available by state, county, or nationwide—and shipshape US Address Verification, you can construct new lists or clean active ones with the swagger of a seasoned captain.
