Open curbside mailbox on a post with a letter inside and the flag raised
About the Mailbox black outline icon
A barrel-topped curbside mailbox stands on a tall post with its door swung open and a sealed envelope resting inside, while the signal flag is raised on the side. It reads as new mail waiting, delivery and postal contact. Use it in email clients, notification empty states, contact pages, shipping trackers and newsletter signup blocks.
The rounded box body, straight post and raised flag form a clear vertical silhouette, and the envelope's crossed fold lines add a recognizable detail at the front. Pair it with envelope, package and post office icons. Below 24 px the envelope crease lines begin to merge.
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.
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.
