How much must marketing mail weigh to be compliant with mailing standards?

For marketing mail to be compliant with mailing standards, it must not exceed a weight of 16 ounces. This maximum weight is established by mailing regulations to ensure that the mail can be processed efficiently and economically by postal services. Items heavier than this threshold typically fall into different mailing categories or classes, which may have different requirements and pricing structures. Therefore, understanding the weight limit for marketing mail helps businesses maximize their mailing efficiency and comply with postal guidelines.
