Brew extracts your brand from your website in about 30 seconds. Every email is on-brand from the start. When you sign in to Brew for the first time, a brand-setup dialog opens. You can’t create emails until at least one brand is extracted, because Brew needs to learn what your brand looks like first.

How Extraction Works

1

Enter your domain

Type your website URL (for example, acme.com). A live logo preview appears as you type. Submit when it looks right.
2

Add anything you already have (optional)

If you have a brand guide, PDF, existing design.md, logo files, or past emails you’re proud of, drop them in. Brew reads these alongside your site, and on any conflict, your uploaded material wins. The domain only fills in whatever gaps your files leave.

Wait about 30 seconds

Brew screenshots your site and runs it through five extraction phases:
  1. Analyzing. Reading your site and any files you uploaded
  2. Researching. Studying your voice, positioning, and signature visual moves
  3. Writing. Drafting your email-design.md: colors, type, layout, and the details that make an email recognizably yours
  4. Assets. Saving logos and key images
  5. Complete. Your brand is ready
The progress dialog updates as each phase finishes.

Open the Brand tab

Once extraction completes, head to the Brand tab in the sidebar to review what Brew wrote and adjust anything that doesn’t look right. The Email Design sub-page renders your email-design.md directly. Open it and edit any line, the same way you’d edit a doc. See Brand identity for everything else you can configure there.

Default API Key

Finishing extraction also issues a default API key scoped to this brand, shown once at the end of onboarding. Copy and save it. Because keys are brand-scoped, deleting a brand and adding another (or extracting an additional brand) runs onboarding again and issues a new default key for that brand. See API configuration for how to manage, rotate, or revoke keys afterward.

What email-design.md Is

Brew doesn’t store your brand as a set of fields. It writes it up as a document called email-design.md, the way a designer would write a brand guide: prose, with exact values where exact values matter (hex codes, fallback fonts) and the reasoning in between (use the accent sparingly, never center the logo). That’s why extraction takes 30 seconds instead of returning instantly: Brew is researching and writing, not just filling in boxes. And it’s why editing your brand later is just editing text. Open the Email Design page, change the line that’s wrong, and every email from then on follows it. Need more than one brand? See Multiple brands.
