Building email campaigns by hand is a design QA problem

Last quarter I watched a teammate spend four hours in Mailchimp — dragging blocks, tweaking padding, checking the preview on mobile — then ship a campaign that had a CTA button with contrast so low it was basically invisible on dark mode. No tool flagged it. She found out from replies.

Kopi generates a complete HTML email from a text prompt in under 5 minutes, then runs an automated design critique before anything ships. Every email gets scored 0–100 across 12+ criteria: layout hierarchy, mobile readability, CTA contrast, and others. The score isn't decorative — it surfaces the specific element failing and why.

The public gallery at trykopi.ai/emails has 400+ emails that scored 80 or above, which is useful if you want to see what the scorer actually rewards before you trust it with your brand.

Two implementation details worth knowing:

# Klaviyo integration
Generate email -> review score -> export directly to Klaviyo campaign draft.
No copy-paste, no HTML file handling.

It also runs as an MCP server, so if you live in Claude Code or Cursor you can generate and score emails without leaving your editor. Brand-specific design systems are supported — feed it your fonts, colors, and layout preferences once and every generation pulls from that context.

The contrast scoring alone has caught things I would have shipped. That's the part I use it for most.
