Hey Product Hunt! 👋 I built Pine Mail because every mail catcher I used for local dev (Mailtrap, Mailpit, MailHog) was great for humans clicking through emails, but none of them were built for the world I actually work in now: AI coding agents running end-to-end tests. When an agent (or a CI script) needs to test "sign up → check the verification email → extract the code → complete the flow," it shouldn't have to poll a REST endpoint in a loop or guess how long to sleep(). So Pine Mail ships: a GET /api/wait endpoint that long-polls until a matching email actually arrives a GET /api/messages/:id/extract endpoint that pulls OTP codes and magic links out of the body automatically a full MCP server (pinemail-mcp) so Claude/Copilot/Cursor can just... use these as tools On top of that I wanted it to be genuinely slim — it's a single Rust binary with the whole React UI baked in via rust-embed, so docker compose up gets you SMTP + a full inbox UI + an MCP server with a hard memory cap, nothing else running. It's fully open source (MIT). Would love feedback, especially from anyone building agentic e2e test suites — what would make this more useful for your workflow?

🚀 Pine Mail just got a major upgrade — SMS support is now ready!

A few days ago, I introduced Pine Mail as a tiny, self-hosted SMTP catcher for development and E2E testing.

Now it goes beyond email. 📬 + 📱

Pine Mail is now a self-hosted Email & SMS catcher built for modern development, automated testing, and AI agents.

What’s included:

✉️ Capture emails locally via SMTP
📱 Capture SMS messages through a REST API or Twilio-compatible webhooks
🔐 Automatically extract OTP codes and magic links
⏳ Long-poll APIs to wait for emails or SMS during E2E tests
🤖 14 MCP tools so AI agents can directly discover and inspect messages
🔍 Email compatibility analysis and heuristic spam scoring
🖥️ A unified web UI for both Email and SMS
🦀 Built in Rust, with a small footprint and zero external runtime dependencies
🐳 Available as a single binary, Docker image, Homebrew package, and more

The goal is simple:

Your tests and AI agents shouldn't need external inboxes, real phone numbers, or SaaS dependencies just to verify an OTP, magic link, email, or SMS.

Run it locally. Capture the message. Extract the code. Continue the test.

Pine Mail is designed to be especially useful for AI-driven development and autonomous E2E testing workflows.
