Which of the following is NOT a feature of Priority Mail?

The correct answer highlights that guaranteed next-day delivery is not a feature of Priority Mail. Priority Mail generally offers delivery within 2-3 days, which provides a reliable and timely service option for customers, particularly for those needing expedited shipping.

While Priority Mail does have a maximum weight limit of 70 lbs and its pricing is based on both weight and distance, the hallmark of the service is that it does not guarantee next-day delivery. This feature is specifically associated with Priority Mail Express, which is the USPS service that promises overnight delivery. Understanding these distinctions—particularly that Priority Mail does not come with a guarantee for next-day service—is crucial for providing accurate information and service to customers.
