What's the difference between e-mail and traditional written documents?

1, fast: E-mail can reach the recipient's mailbox in a few seconds, which is faster than the traditional mailing method, so e-mail has become the mainstream communication method for business and personal communication.

2. Strong flexibility: E-mail can send files, pictures, audio, video and other types of multimedia information, and can be combined and typeset according to needs. At the same time, due to its digital characteristics, e-mail can be easily backed up, archived and retrieved.

3. Low cost: E-mail is low in sending cost, and usually only needs to pay the network fee, without considering the mailing fee, paper printing and other expenses, which makes e-mail more advantageous in cost saving.
