To be CASS Certified, software must pass an annual USPS test to verify and correct addresses to the ZIP + 4® level with 98percent accuracy, among mailing list other requirements. Starting in 2008, CASS(TM) processing now includes DPV and LACSLink for a greater level of accuracy. DPV confirms an address has an actual point mailing list of delivery, while LACSLink identifies and updates business and residential rural route addresses to street-style addresses.
Additionally, mail preparation software will presort and barcode your mailings, helping you qualify for the lowest postage rates and applicable discounts. Here's how one company achieved their goals. A college magazine publisher mailed out thousands of copies of their monthly publication but needed to find ways to cut down on their costs. They investigated and purchased mail preparation software to barcode their mailings for postal discounts.
Not only did the software qualify their mailings for presort discounts resulting in thousands of dollars a year in savings, it also verified and corrected mailing list incomplete and incorrect addresses which dramatically cut down on the amount of returned mail. Step 2: Update it! Another culprit in the high cost of undeliverable mail is customers - they are a constantly moving target.
