A testable, composable, and adapter-based Elixir email library for developers.
Bamboo is an Elixir library for sending email that emphasizes testability, composability, and adapter-based delivery. It provides a clean separation between creating emails and sending them, allowing developers to build emails functionally with pipes and deliver them via various services or custom adapters. It solves the problem of integrating email functionality into Elixir apps in a maintainable and flexible way.
Elixir developers building applications that need to send transactional or bulk emails, especially those who value testability and integration with services like SendGrid or Mailgun.
Developers choose Bamboo for its elegant functional design, built-in support for major email services, and strong testing utilities. Its adapter architecture and background delivery options make it a versatile choice for production email workflows.
Testable, composable, and adapter based Elixir email library for devs that love piping.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Ships with built-in adapters for popular services like Mandrill, Mailgun, and SendGrid, and supports writing custom adapters, making it easy to integrate with various email providers.
Provides a TestAdapter for integration testing without external sends and allows unit testing by asserting against email structs, as demonstrated in the README's testing examples.
Uses plain Elixir functions and piping for email creation, enabling a clean, composable approach that fits naturally into Elixir workflows.
Includes a plug to view sent emails in development, useful for debugging confirmation links and transactional emails without checking logs.
Requires setting up mailer modules, adapters, and environment-specific configurations, which can be complex for simple projects or those new to Elixir's OTP applications.
Relies on community or custom adapters for less common email services; if an adapter isn't available, developers must implement their own, adding development time and maintenance burden.
The default deliver_later strategy uses TaskSupervisorStrategy, which may not be robust for high-volume or queue-based systems, requiring custom strategies for advanced use cases.
