Snail Mail(redirected from P-mail)
Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia, Wikipedia.
A popular slang term for correspondence sent through the post, rather than by e-mail. Snail mail is much slower than e-mail (hence its name) and has become less common for correspondence in which a physical signature or package is not required.
A term often used by Internet aficionados to describe traditional ground mail via the U.S. Postal Service, referring to its relatively slow speed of delivery compared to e-mail.
