Brand system

The Letters identity.

A calm, editorial system: one envelope mark, an ink-and-paper palette with a single coral spark, and type that feels considered. Everything you need to build on-brand.

Voice & principles

How Letters sounds and behaves.

Calm, not loud

Restraint over decoration. White space, hairlines, and one accent — never a wall of colour.

Show the work

Let the email designs carry the colour. The chrome stays quiet so the output shines.

Plain-spoken

Short, warm, human copy. No jargon, no hype — like a note from a thoughtful friend.
