How does express mail differ from regular mail service?

Express mail and regular mail differ primarily in their speed, handling, and cost. While standard postal services rely on mass-processing individual items to ensure efficiency and economy, express mail is designed specifically for expedited conveyance.1

The key differences include:

• Handling: Regular mail is processed in bulk, moving through various sorting offices and transport stages before final delivery. In contrast, express mail receives individualized priority handling to ensure faster transit.1
• Speed: Express services are marketed specifically for their speed, convenience, and reliability, often guaranteeing faster delivery times compared to standard mail.1
• Cost: Express mail is offered at an additional cost compared to regular mail services.1

Historically, services like special delivery were used for urgent items, but these were largely superseded by modern express and priority mail options, which provide more efficient, prioritized logistics for correspondence and goods.21
