About the Mailbox Envelope Flag black filled icon
A curved-top letter box sits on a straight post, with a raised side flag shaped like a sealed envelope to show that mail is waiting. The pairing of container and envelope communicates incoming post, notifications and correspondence, which suits contact pages, newsletter signup blocks, delivery tracking screens, inbox empty states and postal service websites.
The box is a wide rounded rectangle in side profile, the post is a narrow vertical bar, and the envelope flag repeats the classic V fold so it stays legible on its own. It works alongside envelope, parcel and delivery truck icons. Keep it at 24px or larger so the fold lines do not merge.
This is the solid black filled version of the mailbox envelope flag icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
