Cloudflare mailing list

I have used Google Domains for the past five years or so. One of the weirdest things about their email service was that if you wanted a mailing list you had to set up a Google Group. When Google Domains decided to shut down I made the jump to Cloudflare. At the time you could not set up mailing lists with Cloudflare, so I just forwarded the email address to that same Google Group. Recently Cloudflare introduced Email Workers, which I found could do what I needed of a mailing list.

Email Workers

Cludflare email workers “allow you to create custom scripts and process your emails according to your specific requirements”.

Create an Email Worker

Creating an email worker is pretty straight forward. From the Cloudflare dashboard, select Websites > your domain > Email > Email Workers tab.

Now select the Create button.

The following is the code I used

export default {
  async email(message, env, ctx) {
    const forwardList = ["[email protected]","[email protected]"];
    for(const email of forwardList){
      await message.forward(email);
    }
  }
}

Once you Save and deploy you need to create a Email route. Here you determine the email address you want to use and email sent to that address will go to your Email Worker.

That is it. Now mail sent to the email address of the route will go to the worker and then forward to the addresses in your forwardList.
