postal mail vs courier

postal mail vs courier refers to the differences between traditional mail services (such as USPS) and private courier services (such as FedEx, UPS, or DHL). Postal mail is often more affordable, especially for smaller, less time-sensitive packages, and is typically managed by a government agency. Courier services, on the other hand, tend to offer faster delivery, more tracking options, and specialized services for international shipping, often at a higher cost. Couriers are preferred for urgent deliveries, larger shipments, or those requiring more control over transit times.
