What is the difference between first-class mail and standard mail?

The distinction between first-class mail and standard mail hinges on several key factors, primarily speed and service level. First-class mail is designed for quicker delivery, typically ranging from one to three days, depending on the distance. It also offers priority services, such as forwarding and return services, catering to urgent correspondence and important documents.

In contrast, standard mail, which is often used for bulk mailings or less time-sensitive items like advertisements or catalogs, is not prioritized for speedy delivery. This difference in service allows individuals and businesses to choose the most appropriate mailing option based on urgency and budget considerations.

The other options do not accurately reflect the distinctions between first-class and standard mail, as they misrepresent factors such as weight, cost, tracking capabilities, and international mailing restrictions.
