How to Turn Existing Email Designs Into On-Brand Campaigns 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.

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
• Tone and structure that already performs

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

Three ways to bring existing designs into Brew

Brew supports three practical import paths.

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.

2. Connect with Figma

If your team designs email in Figma, connect Figma and paste a frame URL into Brew. Brew converts the frame into a responsive email.

This is useful when:

• Designers work in Figma before marketing builds the email
• You want to preserve layout fidelity
• You need to move from design to sendable email faster
• You want to avoid rebuilding the same layout by hand

Figma import is especially helpful for bigger teams with a brand or design function.

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

The import is just the starting point. The value comes from turning old assets into reusable, adaptable email systems.

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

Why this matters for enterprise teams

Bigger companies often move slower because email production has more constraints: brand review, design review, legal copy, approved layouts, and ESP handoff.

Import workflows reduce that friction. The team does not need to start over. It can use existing approved assets, then let AI adapt them to new goals.

That is how AI becomes useful in real marketing teams. It works with the system that already exists.

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.
