I spent a few hours last month rebuilding a promotional email in Mailchimp — drag, drop, resize, preview on mobile, tweak the CTA button color, repeat. Sent it. Conversion rate was fine. Had no idea whether the layout hierarchy was the reason or despite it.
Kopi takes a text brief and returns a complete HTML email in under 5 minutes. The part I find most useful isn't the generation — it's that every output gets an automated design critique: layout hierarchy, mobile readability, CTA contrast, and 12+ other criteria scored on a 0-100 scale. You know what's weak before it ships, not after.
There's a public gallery at trykopi.ai/emails with 400+ emails that scored 80 or above, which is useful for calibrating what "good" actually looks like across industries and formats — something a blank template library never gave me.
If you're already running Klaviyo, it exports directly to campaigns. If you're working in Claude Code or Cursor, it runs as an MCP server. It also picks up brand-specific design systems — fonts, colors, layout preferences — so the fifth email you generate doesn't look like a fresh start.
I got tired of spending a Tuesday afternoon on one campaign and still shipping something I wasn't confident in. This fixed that specific problem.
