Which mail option requires the mailer to use the FAST system?

The Full-Service Option requires the mailer to use the FAST (Flexible and Scalable Technology) system because it is designed to improve efficiency in processing mail by providing advanced visibility and tracking capabilities throughout the mailing process. This system encompasses various elements, including electronic documentation that streamlines the submission process and allows mailers access to enhanced service features.

By using the FAST system, mailers benefit from a more efficient workflow, as it supports real-time updates and visibility into the mail's journey, which is a hallmark of the Full-Service Option. This option is particularly advantageous for businesses that send a high volume of mail and need to ensure timely delivery and accurate tracking. The integration of the FAST system into the Full-Service Option reflects the modern requirements of mail processing and enhances the overall customer experience.
