About the Envelope black outline icon
A horizontal envelope drawn as a rounded rectangle with two diagonal fold lines running from the top corners down to a small notch at the center, forming the classic sealed flap. It reads immediately as mail, messages, contact and correspondence. Use it for inbox and unread-message buttons, contact forms and footers, newsletter signups, email client navigation, and app notification badges.
Proportions are close to a wide 4:3 rectangle with softly rounded corners, and the flap occupies the upper half so the V shape dominates the silhouette. It pairs with phone, chat bubble and location icons on contact rows. Keep stroke alignment crisp at 16-24 px so the center notch does not blur.
This is the black outline version of the envelope icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
