Email company for humans & AI agents

Email that works for your domain — and your automations

Mailinbox is building modern email infrastructure: catch-all addresses on your domain, a clean inbox, a REST API, and MCP tools so people and AI agents can read, search, and act on mail from one place.

Built like a real email company

Not a throwaway form field. Mailinbox is inbox + infrastructure: receive everything on your domain, organize it, and connect it to the tools you already use.

∞

Catch-all on your domain

Any address works — otp@, support@, agent-7@. Create disposable or permanent identities without new mailbox setup.

▣

Human-friendly inbox

Search, open, and read messages in a fast web UI. Designed for day-to-day use, not only for developers.

{ }

Automation-first

REST API and MCP so internal services and AI agents can list, search, and fetch mail programmatically.

⛨

You own the pipe

Mail lands through Cloudflare Email Routing into infrastructure you control — not a black-box consumer webmail.

✦

Made for AI workflows

Agents can pick an address, wait for OTPs, extract links, and keep notes — without asking humans for setup each time.

◎

Multi-domain ready

Start with mailinbox.pw. Add more domains later that point into the same central inbox service.

API & MCP, ready for agents

One Bearer token unlocks REST and MCP. List mail, search for verification codes, fetch full bodies, download attachments.

  • GET /api/emails — filter by to / from / q
  • GET /api/emails/:id — full message
  • POST /mcp — tools: list_emails, search_emails, get_email, delete_email
