Standard mail, commonly used for mass marketing, has distinct characteristics that differentiate it from other mailing options. One key aspect is that Standard mail does not typically include personal letters. Instead, it primarily consists of bulk mailings like advertisements, catalogs, and promotional materials that do not require individual addressing but can be sent to large distributions.

The requirement for bulk mailing is a hallmark of Standard mail, as it is designed for businesses and organizations seeking to send items to numerous recipients simultaneously. This bulk approach allows for cost-efficiency when mailing large quantities, enabling senders to take advantage of lower rates compared to first-class mail. Additionally, the inclusion of catalogs and advertisements is a significant feature, as these types of materials are specifically aimed at commercial promotion.

Therefore, the assertion that personal letters can be included in Standard mail does not align with its primary function. Standard mail is not intended for personal correspondence, which is primarily routed through first-class mail options.
