MistMail

Overview

MistMail is a Cloudflare-based temporary mail service I built for handling throwaway addresses across multiple domains. Most existing services are either slow, ad-heavy, or limited to a single domain. I wanted one that ran at the edge for low latency, supported dynamic registration across several domains, and had a UI that respected the user's time.

What it does

Users land on the page, get an instantly generated temporary address, and can receive incoming mail in real time. They can pick from multiple registered domains for variety, refresh to get a fresh address, and the inbox view shows messages as they arrive without manual polling.

Tech stack

Cloudflare Workers handle the email routing and API surface. The static frontend is served from Cloudflare Pages. Email reception and storage flow through the edge with minimal latency. The whole stack stays close to the request, which is important for a tool where "feels instant" is a key part of the experience.

What I learned

Building this taught me how productive edge platforms can be when the use case fits. The whole system runs without a single traditional server. Operations are minimal because there's nothing to keep alive between requests. That's a different mental model from server-based development, and once it clicked, it changed how I evaluate which services to put behind a server and which to put at the edge.
