Hi Product Hunt 👋

I built mailfab because I wanted a temporary email service that felt fast, modern, and developer-friendly — with a clean UI and full API access from day one.

**What makes mailfab different:**

🕐 **Instant guest inbox** — No signup. Hit the page, pass Turnstile, get a working email address in one click. The inbox auto-refreshes and you see messages
in real time.

🔀 **Multi-domain random assignment** — Each new inbox picks one at random to avoid domain-level rate limiting.

🔗 **Message sharing** — Share any email or individual message with a public link. The recipient sees a clean, read-only view — no account needed.

📡 **Full OpenAPI** — Every action (create mailbox, list messages, fetch content) is available via REST API with API Key auth. Designed for automation testing,
CI pipelines, and signup flow verification.

🌐 **5 languages** — English, 简体中文, 繁體中文, 日本語, 한국어.

🔒 **Privacy-first** — No real email required. Guest inboxes work in a browser-private session. Messages auto-expire.

⚡ **Cloudflare-native** — Workers + D1 + KV. Low-latency email delivery via global edge deployment.

Thanks for checking it out! 🙏
