Every email marketing tool I've used hands you a drag-and-drop editor, a folder of templates, and a clock. You assemble something that feels right, send it, and find out whether the CTA was readable on mobile after the campaign is already live.
I built kopi to cut that loop short. You write a brief — one paragraph describing the campaign, the offer, the audience — and it generates a complete HTML email in under 5 minutes. Not a skeleton you fill in. A real email: hierarchy, copy, imagery placeholders, CTA, mobile layout.
Here's what that looks like in practice:
Brief:
Black Friday sale for a specialty coffee subscription. 30% off first box.
Target: gift-buyers who haven't purchased yet. Warm, not urgent. One CTA.
What kopi generates:
A complete HTML email with a single above-the-fold hero, a short three-line value prop, a centered CTA button, and a footer with unsubscribe. No lorem ipsum. Structured for a Klaviyo export.
The part I cared about more than generation speed: every output gets scored automatically across 12+ design criteria — layout hierarchy, CTA contrast, mobile readability — on a 0-100 scale. Before you send anything. The public gallery at trykopi.ai/emails has 400+ emails that scored 80 or above, which is a useful baseline for what the rubric actually rewards.
For teams with an existing brand system, it learns your fonts, colors, and layout preferences so you're not correcting brand drift on every generation.
It also runs as an MCP server, so if you're already in Claude Code, Cursor, or ChatGPT, you can trigger a generation and get the scored output without leaving your editor.
Klaviyo export is direct — generate, score, ship.
