How to turn existing email designs into on-brand emails with AI

Not every company starts from a blank page. Many teams already have approved email designs, brand templates, Figma files, or high-performing campaigns from another ESP.

The question is not whether AI can create something from scratch. The better question is: can AI use what already works?

For modern email teams, the answer should be yes.

Key takeaways

Approved layouts already hold header, footer, type, spacing, and legal patterns. Starting over throws that away.
Three import paths cover most teams: upload HTML, connect a Figma frame, or recreate from an image.
After import the file is a normal canvas email. Edit it, save it as a template, generate variants, or send it.
Import is the start. The useful part is turning old assets into a system you can adapt for new campaigns and automations.

Two types of email teams

Most companies fall into one of two groups.

Smaller teams often do not have a design system for email. They need AI to create the first strong version quickly.

Larger teams already have existing designs. They need AI to respect what is already approved, then adapt it for new campaigns and automations.

The second group needs import workflows.

Why existing designs matter

Existing email designs carry a lot of brand knowledge:

Header and footer patterns
Button styles
Typography choices
Spacing and layout density
Image treatment
Legal and unsubscribe conventions, including a working opt-out under CAN-SPAM
Tone and structure that already performs

Throwing that away makes AI less useful. The system should learn from existing work, not replace it.

Ways to bring existing designs into Brew

Brew supports three main import paths. A fourth, forwarding an email from your inbox to Brew, runs the same HTML conversion as an upload.

1. Upload HTML

If you already have email HTML from another ESP or an internal design system, upload it into Brew. Brew imports it as an editable email on the canvas.

This is useful when:

You have production-ready HTML from a past campaign
You want to migrate templates from another ESP
Your team has a coded email design system
You want the most accurate recreation of structure and spacing

Once imported, you can ask Brew to rewrite, rebrand, shorten, localize, or turn the design into variants. A tight brief still helps. See how to brief an email agent.

2. Connect with Figma

Use a frame URL that includes a node-id. Connect Figma in Brew, then paste the frame link into chat. Choose the actual email frame, not an entire design board.

Prepare the frame with clear sections, readable text, and the images the email needs. A web-page layout may need simpler columns for email clients.
Import the selected frame. Review the converted email at desktop and mobile widths.
Check every destination URL and personalization field. A screenshot or design frame is not proof that the exported email contains working links.
Edit the copy and layout on Brew's canvas. Keep the original frame as a visual reference.
Send a test and use rendering checks for the clients your audience uses. Then send from a verified Brew domain or export to a supported platform.

Agents can request the import through Brew's tools after the Figma connection is authorized. Follow the Figma setup guide for current requirements. Keep the design file and final email accessible to the person reviewing the send.

3. Upload an image to recreate

If all you have is a screenshot or visual reference, upload the image. Brew recreates the structure and style as an editable email.

This is useful when:

You like an email but do not have the HTML
You have screenshots of older campaigns
You want to borrow a structure without copying the brand
You want Brew to create a new version in your style

What happens after import?

Imported designs become normal Brew emails on the canvas. That means you can:

Edit manually
Edit with AI
Save as a template
Set as a reference email
Generate variants
Send a test preview
Send to an audience
Export to HubSpot, Klaviyo, Mailchimp, Brevo, and other ESPs

Check the imported email against the approved original before using it as a reference for future campaigns.

How to choose the right import path

Starting point	Best path
Existing ESP HTML	Upload HTML
Figma frame	Connect with Figma
Screenshot or image	Upload image to recreate
Email in your inbox	Forward to Brew
No existing design	Start with a prompt

Where Brew fits

Brew supports both blank-page creation and existing-design imports. Start from a prompt if you need a new direction. Import HTML, Figma, or an image if you already have a design you want Brew to use.

Either way, the result lands on the canvas as an editable email you can send, schedule, or export.

Imported legal footers still need a real unsubscribe, not only a lookalike block. RFC 8058 is the one-click header. For copy after the layout is in, use how to write marketing emails and email marketing best practices. To contact us about this article, write Brew support.
