04every email

Every email you send, one system.

From the campaign to the receipt to the carousel that moves in Apple Mail. Same components, so every touchpoint looks like the same brand. All six types

Three brands. One system.

Every email above comes from one set of components across three demo brands. Only the brand tokens change, light and dark. That’s what we build for you.

05how it is built

One email, four layers.

A real email from the demo system, taken apart. Your brand lives in the first layer only, which is why a new brand or property takes a day, not a rebuild.
  1. 01 · tokens

    Your brand, as data.

    Colour, type, spacing and corners, light and dark, defined once. Nothing else in the system knows a hex code.

  2. 02 · components

    Parts that only fit one way.

    Header, hero, text, button, footer: each hand-coded for Outlook, Gmail and Apple Mail, and tested on every change.

  3. 03 · assembly

    Every email from the same parts.

    Your team chooses blocks and writes words. Layout, brand and code stay locked, so nothing drifts.

  4. 04 · everywhere

    Light, dark, every client.

    The same email holds its brand in dark mode, in classic Outlook and on a phone, because the system was built for all of them.
