What are the weight restrictions for Marketing Mail eligibility?

The correct choice indicates that for Marketing Mail eligibility, the weight must be less than 16 ounces. This standard allows for a broad range of promotional and advertising materials to be mailed efficiently, making it suitable for various types of marketing campaigns. Items that are heavier than 16 ounces would not qualify for Marketing Mail rates and would instead fall under different classifications, such as First-Class or Priority Mail, which have different pricing structures and delivery timelines. Understanding these weight restrictions is crucial for businesses in order to manage mailing costs while ensuring that their marketing initiatives reach their intended audience effectively.
