What is the maximum weight for packages sent by Media Mail?

The correct answer reflects the maximum weight limit for packages sent via Media Mail, which is indeed set at 70 pounds. Media Mail is a cost-effective service offered by the Postal Service specifically for sending educational materials, such as books, manuscripts, and certain other media items.

The weight restriction is significant because it allows for a broad range of educational materials to be mailed economically while ensuring that the service remains viable for both the sender and the Postal Service. Sending packages over 70 pounds would fall into different mailing categories, thus negating the benefits of the Media Mail service, which is designed to cater specifically to lighter, media-centric items.

Being aware of the weight limit is crucial for anyone utilizing this service to avoid potential delays or complications with postage. The other weight options exceed the established limit, which is why they would not be valid choices for Media Mail.
