Every new campaign at our last company started the same way: dig through old Figma files, copy hex codes into the ESP, argue about whether the CTA button was 'forest green' or 'dark green,' get it wrong, send anyway.
kopi's brand design system skips that loop. You give it your fonts, colors, and layout preferences once. Every email it generates after that applies those constraints automatically — it doesn't ask, it doesn't drift, it doesn't approximate.
The part that surprised me during testing: the automated design critique catches the drift you'd miss anyway. Every generated email gets scored on 12+ criteria — layout hierarchy, mobile readability, CTA contrast — on a 0-100 scale. That score runs before export, not after a QA round.
The public gallery at trykopi.ai/emails has 400+ emails all scoring 80+. Worth looking at if you want to calibrate what that score actually means in practice.
Prompt: "Flash sale for our summer collection, 30% off, ends Sunday, target: existing customers"
Output: Complete HTML email, brand fonts and colors applied, CTA contrast score: 94/100
Generation time: under 5 minutes
Klaviyo export is direct. Also runs as an MCP server for Claude Code, Cursor, and ChatGPT if you're building email generation into a larger workflow.
