Every Klaviyo template I built looked fine in the editor. Then I'd check it on my phone: CTA button too small to tap, hero text wrapping at 3 words per line, image-to-text ratio completely off. I had no feedback loop until the campaign already went out.
kopi runs an automated design critique on every email before it ships — layout hierarchy, mobile readability, CTA contrast, and 12 other criteria, scored 0–100. It's not a linter for code; it's a linter for visual design decisions that actually affect conversions.
The brand system angle matters here: the score is calibrated to your specific fonts, colors, and layout preferences, not some generic email standard. You define your design system once, and every generated email gets scored against it. If your brand uses a high-contrast CTA on a dark background and the generator drifts from that, the score reflects it.
Generation takes under 5 minutes from a text prompt to a complete HTML email. The public gallery at trykopi.ai/emails has 400+ emails that scored 80 or above — worth browsing if you want to see what the scorer actually rewards.
Klaviyo export is direct. It also runs as an MCP server for Claude Code, Cursor, and ChatGPT if you want to build generation into a workflow.
