Which is NOT a characteristic of the Presort Software?

The correct answer highlights that evaluating letter sizes is not a characteristic of Presort Software. Presort Software is primarily designed to optimize the way mail is processed for bulk mailing, ensuring that it meets postal regulations and can take advantage of presorting discounts.

This software focuses on managing the documentation for mailings, ensuring accuracy in the data provided, and certifying that mail pieces comply with specific mailing standards. Each of these functions helps streamline the mailing process, making it easier for businesses to handle bulk mail efficiently.

In contrast, while the software may help users understand formats and standards, its core functionalities do not include the specific evaluation of letter sizes, as that relates more to physical mail preparation and sorting rather than a software capability.
