Snail Mail Was Named in Contrast to Email
A snail is a mollusc with a coiled shell. The phrase snail mail appeared only once electronic mail existed to compare it with.
A snail is a mollusc with a spiral shell it can withdraw into. *Snail mail* is a retronym — a name invented for something old only after something new made a distinction necessary. Nobody said snail mail before email existed, just as nobody said *acoustic guitar* before electric ones, or *landline* before mobiles. Most snail shells coil clockwise; a rare left-coiling individual usually cannot mate with the others, since their anatomy no longer aligns.

What is a retronym?
A new name for an existing thing, made necessary when something new needs distinguishing from it, like snail mail or acoustic guitar.
Why can't left-coiling snails mate?
Because their reproductive anatomy is mirrored, so it no longer aligns with that of the ordinary right-coiling majority.
