What does the CASS Summary Report provide in terms of mailing?

The CASS (Coding Accuracy Support System) Summary Report is essential in the context of mailing as it focuses on the accuracy of address data which directly impacts the efficiency of mail delivery. The report evaluates the performance of an address processing system by examining how effectively it can verify and standardize addresses against the USPS database.

When it comes to mailing, the requirement for coding accuracy is critical because accurate addresses ensure that mail is delivered to the correct destinations without issues such as returns or delays. By providing insight into the accuracy levels of mailing lists, the CASS Summary Report helps organizations maintain high standards for address data, which is particularly important as maintaining an updated and accurate mailing list can directly affect the return on investment in direct mail campaigns.

The other options, while related to mailing processes, do not specifically highlight the CASS Summary Report's focus on coding accuracy. Summarizing mailing costs, detailing mailing rates, or listing common errors reflect different aspects of mail preparation and submission but do not directly align with the primary purpose of the CASS Summary Report in terms of ensuring address verification and coding accuracy.
