A mailbox does two jobs: it holds the mail and it sets the tone at the front of the house. Wall mount boxes hang beside the door or on a fence. Post mount boxes stand at the curb and are the kind a carrier reaches from the road. Material, lock and capacity vary a lot, so the details below matter.
The six mailboxes here run from a large open-lid wall box to lockable steel models and two curbside post mount boxes. Sizes, materials and features come from each product’s listing page. We have not used these mailboxes ourselves. Claims about coatings, locks and approvals are the makers’ own.
