Snail mail is a derogatory retronym – named after the snail with its proverbially slow speed – used to refer to letters and missives carried by conventional postal delivery services. The phrase refers to the lag-time between dispatch of a letter and its receipt, versus the virtually instantaneous dispatch and delivery of its electronic equivalent, e-mail.
It is also known, more neutrally, as paper mail, postal mail, or land mail. [Wikipedia]
