usps first class versus priority

usps first class versus priority highlights the differences between two of USPS’s most commonly used mail services. First-Class Mail is an affordable and slower option, mainly for letters and lightweight packages. It provides delivery within 1–3 business days, depending on the destination. Priority Mail, however, is faster and offers guaranteed delivery within 1–3 days, with the added benefits of free tracking, insurance, and the ability to ship heavier packages. Businesses often opt for Priority Mail when speed is important.
