Postal express is called EMS for short, that is, EMS is a kind of postal service, just like the relationship between Shenzhouxing and mobile communication, which mainly uses air transportation to speed up delivery. Generally speaking, it takes 1-4 days to arrive according to the distance of the area.

E-mail is an economical express service specially launched by China Express Service Company for personal e-commerce. Adopting the whole express road and land transportation mode, the price is much more favorable than that of ordinary EMS, which saves more costs for individual sellers engaged in e-commerce.

Express delivery, also known as express delivery, is a door-to-door logistics activity with postal function, that is, express delivery companies deliver customers' goods quickly by rail, road, air and sea.

In many ways, express delivery is superior to postal service. In addition to the faster delivery to the destination and the need to sign for it, many express delivery companies now provide services such as mail tracking function and delivery time commitment according to customer needs.

So the charge for express delivery is much higher than that for ordinary mail.

Express companies can operate on different scales, from serving specific towns to serving regional, transnational and even global services.
