Overview
Spare Mailbox gives you a throwaway email address instantly — no signup, no password, no cookie wall. Open the site, get an address, receive mail in seconds, and keep spam out of your real inbox.
What makes it useful beyond the usual temp-mail site:
- Free public API. Create an inbox, list messages, and fetch a message body over plain HTTP. No account needed to start, so you can wire it into signup tests, QA runs, and CI without ceremony.
- MCP server for coding agents. Point Claude, Cursor, or any MCP client at https://mcp.sparemailbox.com/mcp and your agent can create its own disposable inbox and read the confirmation email itself — no copy-pasting verification codes between a browser and a chat window.
- Attachments are kept, not dropped, so you can actually test receipts, invoices, and exports.
- HTML is sandboxed before it renders, so tracking pixels and remote content don't phone home.
- Available in 19 languages.
Built for developers testing signup and password-reset flows, QA engineers who need a fresh address per test run, and anyone who just doesn't want to hand over their real address to download a PDF.
Runs on Cloudflare Workers, D1, and R2 — fast everywhere, and cheap enough to keep the core free.

Great tool for creating temporary email addresses quickly and easily. The API integration is especially useful for testing and automation. Simple, convenient, and developer-friendly
