About the Mailbox black outline icon
A classic curb mailbox with a rounded tunnel top and a flat front door stands on a straight post, with the signal flag flipped up to show mail is waiting. The raised flag is the detail that turns it into a notification rather than an empty box. Use it for inbox and new-message states, contact and address pages, newsletter signups, delivery notices and moving or change-of-address flows.
The arched body and vertical post form a steady T-shaped silhouette, and the flag hooks over the top edge so it stays visible against the curve. Pair it with envelope, letter and delivery truck icons in a mail set. At 16px keep the flag, since it carries the state.
This is the black outline version of the mailbox icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
