What is guaranteed with Priority Mail Express?

Priority Mail Express offers a service that includes guaranteed delivery 365 days a year, which includes weekends and holidays. This service is particularly valuable for customers who require urgent document and package delivery, ensuring that their items arrive on time regardless of the day. This is a distinguishing feature of Priority Mail Express compared to other shipping services, which may not guarantee delivery on holidays or weekends.

The other options do not accurately represent the features of Priority Mail Express. For instance, free shipping supplies are available, but this is not a guarantee specific to Priority Mail Express. Tracking is always provided with Priority Mail Express shipments, and delivery does not only occur during business hours; it is designed to deliver at any time on the scheduled delivery day.
