Lucas Duval built and open-sourced his own email open tracking
Lucas Duval got tired of paying for email open tracking, so he built his own and open-sourced it. MailTrackMCP runs on Cloudflare Workers and ships with an MCP server, so his agent simply tells him who opened what, and the Cloudflare free tier covers it. Email tracking has long been a thin feature sold as a subscription: a pixel and a dashboard. Swap the dashboard for an agent and the hosting for a Worker, and the whole product fits in a repo. Another small SaaS, quietly headshot.
