<Tip>The `email` application runs on port 3003.</Tip>

`zopio` comes with [`react.email`](https://react.email/) built in, allowing you to create and send beautiful emails using React and TypeScript.

`react.email` has a preview server, so you can preview the emails templates in the browser.

To preview the emails templates, simply run the `email` app:

```sh Terminal theme={"system"}
pnpm dev --filter email
```
