What is the primary purpose of the First Class mail service?

The primary purpose of the First Class mail service is to send letters and small packages quickly. First Class mail is designed for personal correspondence, important documents, and small items, featuring faster delivery times compared to other mail classes. This service prioritizes speed and reliability, ensuring that letters and lightweight parcels arrive at their destinations promptly, often within one to three business days.

While other types of mail may serve specific needs, such as bulk mail for mass distribution or promotional materials, First Class mail is specifically tailored for individual items requiring expediency and a higher standard of handling, making it the ideal choice for sending letters and small packages efficiently.
