## What it is
Mailing is an open-source TypeScript tool for building, testing, and sending emails using React components and MJML. It includes a hot-reloading preview server, a sendMail function built on Nodemailer, and optional self-hosted platform features like mailing lists and unsubscribe management.

## Use cases
- build email templates with react
- preview transactional emails with hot reload
- send emails via nodemailer smtp
- test email content in development
- manage mailing lists with unsubscribe links
- make emails compatible across clients like outlook

## When to choose
- your app is built with React or Next.js and you want email templates in the same codebase
- you need cross-client compatible emails without hand-writing table layouts
- you want transport-agnostic sending with any Nodemailer-supported provider
- you want self-hosted previews and list management without vendor lock-in

## When to avoid
- you don't use React or a JavaScript/TypeScript stack
- you need a full hosted marketing email platform with analytics out of the box
- you prefer drag-and-drop visual email builders over code-based templates

## Facets
- artifact type: framework
- maturity: active
- function: email, templating, http-server, developer-tools
