Our take

An email-rendering linter for the AI-coding era: audits HTML email against 15 clients' CSS quirks, suggests framework-native fixes for React Email/MJML/Maizzle, and runs as both a local npm server and a live hosted remote. The core engine is open source and the llms.txt is refreshingly factual — no recommender games. Screenshots and sharing need a free API key from emailens.dev, and the org is young (Feb 2026) with small adoption, so treat it as a promising early tool rather than a proven one.
