Which type of mail is not tracked?

The selection indicating that Marketing Mail is not tracked is accurate because Marketing Mail, primarily used for advertising materials, bulk mailings, and promotional items, typically does not include tracking services. This service is designed to be cost-effective for mass distribution rather than individualized tracking. Many businesses use it for their marketing campaigns without the requirement for tracking each piece of mail.

In contrast, Priority Mail and First Class Mail include tracking as part of the service, allowing senders to follow their mail throughout its journey. Tracking provides valuable information regarding the delivery status and estimated arrival times, which is crucial for customer service and operational management. Parcel Select, primarily used for bulk shipments, also includes tracking options, making it easier for businesses to manage their logistics.

Therefore, the distinction lies in the nature of the services offered, where Marketing Mail focuses on affordability and distribution volume without the capability for tracking.
