Free temporary email on Cloudflare

What you get

• Zero server and operational cost: It runs on Cloudflare's generous free tier (100,000 Workers requests per day, free Email Routing, and Pages hosting) without renting an external server.
• Custom domain and unblockable addresses: Unlike general disposable email services, it generates single-use addresses with your own domain that do not get caught in websites' blacklists.
• Fast email parsing with Rust and WASM: Processes complex incoming MIME, multipart, and HTML-content emails in milliseconds thanks to a WebAssembly module compiled with Rust.
• Telegram bot and instant notifications: Receive notifications directly via Telegram when a new email arrives, read the message content, or instantly create a new address using bot commands.
• Automatic cleaning and secure access: Automatically clears old messages and attachments after a set period; prevents unauthorized access with an admin password.

How to get started and installation options

To deploy the project, having a Cloudflare account and a domain name managed on Cloudflare DNS is sufficient. You can either deploy via a graphical interface by connecting a GitHub repository with a single click using Cloudflare Pages, or you can publish the D1 database and Worker functions from your local environment via the Wrangler CLI.

Technical architecture and working principle

• Cloudflare Email Routing integration: All MX traffic destined for your domain is handled by Cloudflare infrastructure and routed directly to the catcher Worker function via the catch-all rule.
• Edge Worker and Rust WASM parser: The incoming email stream (raw stream) is transferred to the optimized Rust WASM engine running inside the Worker to quickly parse headers, body, HTML, and attachments.
• Cloudflare D1 and R2 storage: Email texts and metadata are stored on Cloudflare D1, which is an edge SQLite database. File attachments are optionally written to Cloudflare R2 object storage.
• Modern single-page application (SPA): The user-friendly web interface is served with zero latency via Cloudflare Pages' global CDN network.
• REST APIs and external integrations: Offers the ability to generate new email addresses and query the inbox via REST API endpoints for automated tests or third-party software.

Frequently asked questions

• Is Cloudflare's free plan enough for personal use? Yes. The Cloudflare free tier offers 100,000 Worker requests per day, free Email Routing, and a D1 database quota. For personal use and small teams, it is nearly impossible to exceed these limits, and the system runs at completely zero cost.
• Is a custom domain required to use the service? Yes. To receive emails, you must have a domain name (or subdomain, e.g., mail.yourdomain.com) managed on Cloudflare DNS. This allows you to easily bypass sites that block public temporary email services.
• Are incoming emails stored permanently? No, this is a temporary email service. As the system administrator, you can set the retention period for emails from the panel (for example, 1 hour, 24 hours, or 7 days); expired records are automatically deleted from D1 and R2 storage.
• Can email replies be sent outbound via the service? Yes. Although Cloudflare Email Routing only supports receiving emails, when a project is connected to Resend, Brevo, or a custom SMTP server API, it also supports sending emails to the outside world and replying from the web panel.
