Historical note · January 2026 · Describes Brew as of January 2026. For current behavior, see Set a Design Baseline.
Reference emails have been retired. Brand files replaced them: a markdown spec (email-design.md) gives Brew a design baseline that is more precise and easier to version. See Bring your own brand file or Set a design baseline. This post stays up as a historical record.

What Shipped

By default Brew is highly creative: every generation tries a different layout and structure. Great when you’re still figuring out your look, less great when you want consistency. Now you can set a reference email. Point Brew at an email whose design you like. It studies the structure, spacing, and layout. Then it applies your own brand identity (colors, fonts, voice) to every email it generates from a prompt. It’s a design guide, not a template. Brew learns the patterns and applies them to new content; it doesn’t copy the email. You can even use a competitor’s email, since Brew learns the structure, not the brand.

How to Use It

1

Add a reference

Three ways in. Browse Brew’s email gallery and pick one. Forward an email you like to hello@email.brew.new.Or generate an email in Brew and refine it until the design is right. Save it as a template, then set it as your reference from the Brand tab.
2

Generate from a prompt

Start a new email or automation and prompt as usual. Brew follows the reference for layout and structure, and applies your logo, colors, and fonts on top.
3

Replace it anytime

You keep one reference at a time. Set a new email as the reference and it replaces the old one, or remove it from Brand, then Settings.
A remixed template takes priority: when you remix a template, the reference email is ignored for that generation. The reference only applies when you generate from a prompt.
