Snail mail意思

"Snail mail" is an informal term used to refer to traditional postal services, as opposed to electronic mail (email). The term "snail mail" is a playful, derogatory comparison to the slow pace of a snail, implying that it is slower than the instant or near-instantaneous communication methods offered by email and other digital messaging services.

The use of "snail mail" suggests that the traditional postal system is outdated and less efficient than digital communication, which can be sent and received almost instantly across the globe. However, snail mail still has its uses and charm, especially for personal or official communications that require a physical document or a more formal approach.
