What are the similarities and differences between e-mail and traditional postal letters?

E-mail refers to the communication mode of transmitting letters, documents, materials and other information by electronic means. Users can contact network users in any corner of the world at a very low price (no matter where they are sent, they only need to pay the telephone and internet fees) and in a very fast way (they can be sent to any destination in the world you specify in a few seconds). These emails can be in various ways, such as text, images and sounds.

At the same time, users can get a lot of free news and special emails to realize easy information search. This is unmatched by any traditional way.

Traditional mail originally refers to writing letters, but later it developed into mailing parcels, which is certainly not as fast as e-mail. Traditional mail also has the advantage of sending items, which is incomparable to e-mail. But if you want to send it to a regular courier company or post office, the possibility of mail falling is very small.

The workflow of e-mail and traditional e-mail is to send it to the post office first and then to the target users. The difference is that e-mail can be stored for a long time when it is sent to an e-post office. Traditional mail is sent to the traditional post office, and the post office does not save it after sending it to users.
