## What it is
EmailBuilder.js is a free, open-source, block-based email template builder for developers that outputs clean JSON or HTML rendering well across email clients. It can be embedded in apps or self-hosted, with each content block available as its own npm package.

## Use cases
- build email templates without writing HTML tables
- embed a no-code email editor in my SaaS app
- generate responsive transactional emails from JSON
- let non-developers design marketing and receipt emails
- self-host an open-source email builder for my team
- create welcome, OTP, and password reset email templates
- convert email template JSON to HTML before sending

## When to choose
- you need an embeddable or self-hosted email builder with MIT licensing
- you want JSON-based email templates rendered to client-safe HTML
- your team mixes developers and non-developers designing emails

## When to avoid
- you need a full email sending service rather than a template builder
- you want a hosted drag-and-drop editor with zero setup
- you need rich marketing automation features like campaigns or analytics
