About the Inbox Alert Envelope black outline icon
An open envelope is shown from the front with its flap folded down and the diagonal seams meeting at the center, and a circular badge holding an exclamation mark overlaps the top right corner. Together they signal an important message, a delivery problem or a warning in the inbox, which suits email clients, notification centers, help desk dashboards, newsletter tools and error state screens.
The badge breaks the envelope outline, a standard overlay pattern that makes the alert read before the mail shape does. Swap it for the same envelope with check, clock or lock badges to build a full mail status set. At 16 px the exclamation stroke thins out, so 24 px is a safer minimum.
This is the black outline version of the inbox alert envelope icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
