Build an on-brand email system for our weekly newsletter and promos.

  1. Pulled the brandLogo, 2-typeface scale, 4-color palette, voice
  2. Built the componentsHeader, typography, buttons, footer, dark mode
  3. Shipped to the toolComponents landed in Customer.io
  4. Assembled the first emailNewsletter shipped in 15 minutes, on brand

The system shipped to Customer.io and the first newsletter assembled in 15 minutes — on brand, no hand-designing. The writer picked the components and filled the content; the system held the brand. Every send since has shipped consistent, which is the point of the system.

An email template designer is the system that makes every email on-brand without hand-designing each. It fixes the components — the header, the typography, the colors, the buttons, the footer — so the writer assembles, not designs. The system is what separates a brand that ships consistent email from one that ships a different look every send.

What is an email template designer?

A system of reusable components — header, typography, colors, buttons, footer — that the writer assembles into an email without designing each. The system fixes the brand so every email ships consistent and the writer spends time on the content, not the design.

Build the system

  • Header, typography, colors, buttons, footer
  • Components that stay the same; layouts that change
  • One source of truth for the brand

Ship consistent email

  • Writer assembles, does not design
  • Every email on-brand without hand-designing
  • Update the system once, propagate everywhere

How does a brand email system template differ from a one-off?

A one-off is designed per send; a system is designed once and assembled per send. The one-off ships a different look every time; the system ships a consistent look every time. The system is what makes a brand recognizable in the inbox.

What components do on brand email templates need?

A header with the logo, a typography scale, a color palette, a button style, a footer with the unsubscribe. The components are the parts the writer assembles; the system is the parts that stay the same. The components are what make the system a system.

How does an email design system handle cadence?

By fixing the components, not the layout. The writer assembles the components into the layout the send needs — a newsletter, a promo, a launch — without redesigning the components. The system handles the brand; the writer handles the layout.

How the email template designer fits your stack

The agent reads your brand guidelines, builds the component system, and ships it to your email tool so the writer assembles from the system. It pairs with the newsletter and promotional email templates.
