## What it is
Bamboo is an adapter-based email library for Elixir that separates email creation from delivery, with built-in adapters for services like Mailgun, SendGrid, Mandrill, SparkPost, and Postmark. It integrates with Phoenix, supports background delivery via deliver_later, and provides helpers for easy unit and integration testing of emails.

## Use cases
- send transactional emails from an Elixir or Phoenix app
- test email sending in Elixir without actually delivering mail
- switch email providers like SendGrid or Mailgun via adapters
- send emails in the background without blocking requests
- preview sent emails during development
- render emails using Phoenix views and layouts

## When to choose
- you're building an Elixir or Phoenix application that needs to send email
- you want easily testable email code with assertions against email fields
- you need adapter-based support for multiple mail delivery services
- you want background email delivery out of the box

## When to avoid
- your project is not on the Elixir/Erlang BEAM ecosystem
- you need an email service with no existing Bamboo adapter and don't want to write one
- you only need raw SMTP sending with no abstraction
