Resend strips email infrastructure down to its API-shaped bones: a pure-black canvas, off-white monospace type, and exactly one chromatic color — a deliverability green that fires only when a message lands. The visual language borrows the spartan confidence of a well-formatted terminal session and refuses every ornament that doesn't ship bytes.

The result is a brand that reads like clean code. Cards are bordered, never shadowed. Buttons are pills or rectangles, never gradients. Typography toggles between Inter for interface and JetBrains Mono for everything that matters — which, in Resend's world, is most things.
