What is a characteristic of Priority Mail Express?

Priority Mail Express is recognized for its reliable and convenient delivery service which includes tracking capabilities. This characteristic allows customers to monitor their shipments in real time, providing peace of mind and updated information regarding the status of their packages. The tracking service enhances the overall experience, ensuring that both senders and recipients are informed at each step of the delivery process.

In contrast, while free insurance is a valuable feature of Priority Mail Express, it is not the defining characteristic that distinguishes it. The delivery timeframe is another critical aspect, but it typically guarantees delivery within 1-2 days rather than 5-7 days. Additionally, while some packaging options can involve additional charges, Priority Mail Express provides certain flat-rate envelopes at no extra cost which might make the idea of packaging not being included misleading for this service.
