## What it is
Bootstrap Email is a stylesheet, compiler, and CSS inliner that lets you write HTML emails using Bootstrap-like syntax and compiles it into table-based markup that renders consistently across email clients. It is distributed as a Ruby gem with CLI, Ruby, and Rails integrations plus an online editor.

## Use cases
- build responsive html emails with bootstrap classes
- inline css for html email compatibility
- make emails render consistently in outlook and gmail
- compile email templates into table-based html
- send transactional emails with styled html from rails
- avoid email client quirks when writing html email

## When to choose
- you already know Bootstrap or Tailwind and want familiar syntax for emails
- you need emails that render reliably across Outlook, Gmail, Apple Mail, and Yahoo
- you are on Ruby or Rails and want easy integration

## When to avoid
- your stack is not Ruby-based and you prefer a Node or Python email toolchain
- you need full custom CSS control beyond the supported Bootstrap-like class set
- you only send plain-text emails
