Cloud Mail questions

What is Cloud Mail?

Run a multi-user mail service on your own domain with attachments and an admin panel. It’s an open-source, self-hosted alternative to Gmail. It runs on Cloudflare Workers in your own account.

What does Cloud Mail set up in my Cloudflare account?

Workers AI, Cron trigger, D1 database, KV namespace and R2 bucket. They are created in your account, so the data stays yours.

How do I deploy Cloud Mail?

It installs from the command line. Follow the steps in the maillab/cloud-mail README.

Is Cloud Mail free and open source?

Yes. It’s published under the MIT licence. Running it uses your own Cloudflare account, and small setups usually fit in the free plan.

How do I update Cloud Mail?

Pull from the original repository and redeploy: add https://github.com/maillab/cloud-mail.git as an upstream remote, run git pull upstream main, then npx wrangler deploy.
