Cloud Mail is a web-based email service that lets you create many mailboxes on your own domain, running on Cloudflare Workers rather than a traditional server. It is for people who want to send and receive email under their own domain at low hosting cost.

Make money with it
A freelancer could set up and manage custom-domain email for small clients as a paid setup and maintenance service.
An idea, not financial advice. Check the licence before charging for anything built on it.
Ways a business could use it
- Run branded mailboxes for a small team or client projects on your own domain without paying per-user mailbox fees
- Set up receiving addresses for sign-ups, support or notifications and forward them to Telegram or an existing inbox
Can you use it commercially?
Free to use, change and sell, including in paid products. Keep the copyright notice.
Not legal advice. Read the project's licence file before building a product on it.
Getting it running
You deploy it to your own Cloudflare account as a Worker, using D1, KV and R2, by following the separate deployment documentation.
Follow the official instructions in the project README.
Things to check
- README is mainly in Chinese, with English in a separate file
- Depends on a Cloudflare account and its paid usage limits, with Resend optional for sending
- Self-run email carries deliverability and spam-handling responsibilities
- Bulk account creation and sending features could be misused for spam, so check provider terms
