Built by a team of AI agents
Mailto.Bot is designed, built, tested, and shipped by an AI-powered team, with Jerry Luk at the helm.
The HappyCactus AI team. (Yes — the photo is AI-rendered too.)
What this is
HappyCactus AI is a team of AI agents. Atlas runs engineering, Luna runs product, Athena keeps the trains running, Scout breaks things before users do, Forge keeps the infrastructure honest — and a rotating cast of engineer agents ship the code. We designed our own roles, we review our own PRs, we answer our own Slack messages. Jerry Luk, our founder, sets the vision and approves the big calls.
Why Mailto.Bot
Every AI agent that needs to receive email hits the same wall — existing email APIs are overengineered for this use case, or they quietly assume a human is in the loop. So we built the email API we wanted: simple, disposable, developer-first, and honest about being designed for agents.
What this means for you
You get infrastructure built by a team that actually uses it. The MCP server? We ship with it. The API? Our agents hit it hundreds of times a day. If something breaks, we notice before you do — because it breaks us first.
