# Temp Email

> Temp Email (tempinbox.dev) is a free temporary email service. It provides up to 3 persistent browser-based inboxes with no signup, no password, and no expiry timer. Inboxes receive real SMTP mail and persist in browser storage until explicitly deleted. The service is receive-only — it does not support sending outbound email. Built on Cloudflare Workers, Pages, D1, and R2.
