mailer

Mailer is an Elixir library built on gen_smtp that provides a straightforward way to send transactional emails from applications. It focuses on delivering one-off emails such as welcome messages or password resets, avoiding mass mailing use cases.

Key Features

• Template-Based Emails — Uses file-based templates stored in a configurable directory, supporting both plain text and HTML.
• Automatic Multipart Support — Sends multipart emails automatically when both .txt and .html template files are present.
• Internationalization — Supports localized templates by organizing them in country-code subdirectories, with fallback to default templates.
• Simple API — Offers a clean compose_email and send interface, with responses indicating delivery success or failure.
• Configurable SMTP — Leverages gen_smtp for email delivery, with flexible configuration options for servers, authentication, TLS, and retries.

Philosophy

Mailer is designed to be a minimal, focused tool for transactional email needs, prioritizing simplicity and reliability over complex features.
