About the Mailbox black filled 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 solid black filled version of the mailbox icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
