This wiki has been updated 11 times since it was first published in May of 2020.

They feature an inwardly or outwardly opening flap that is often spring-loaded for protection against the weather.

Editor's Notes

August 28, 2020:

In 1863, the US Post Office Department began delivering mail to home addresses, however, up until 1916, mail carriers would knock at the door and wait for someone to answer. It was estimated that each mailman lost over 1.5 hours each day waiting for people to come to the door. To solve the problem the Post Office Department decreed that every house must have a mailbox or letter slot in order to receive mail. Modern designs are available in a variety of shapes, styles, and finishes that are sure to match your existing hardware and complement your style of door.

Brass, iron, and aluminum are the most common materials for mail slots, due to their weather-resistant and anti-corrosive properties. The Skandh Aluminium is a simple, no-frills option with a plain fronted, spring-loaded flap. Similarly, the CR Laurence No-Draft is basic to look at, however, it includes a flap on the inside, and has two internal brushes, as added protection against the cold weather. The Gibraltar Mailboxes MS00RC03 and the Brass Accents Mail Slot are both modern-looking options that are made from brass, but are available in a range of metallic finishes, and have a matching frame for the inside.

If you're looking for something with more traditional or antique styling, the Skandh Black Antique, and the Skandh Iron are both sturdy options with a black powder-coated finish, while the latter incorporates a useful door knocker, too. Solid brass offers an antique look that is highly sought after nowadays. The Adonai Hardware Letter Plate, the House of Antique Hardware Standard Bungalow, and the Halo AdirHome Italian all fit into this category and are notable due to their texture, detailing, and bronzed patina.
