An RFC2822-compliant Elixir library for building, rendering, and parsing composable email messages.
Mail is an Elixir library that implements the RFC2822 email standard, allowing developers to programmatically build, render, and parse email messages. It solves the problem of generating standards-compliant emails in Elixir applications, supporting both simple text emails and complex multi-part messages with HTML and attachments.
Elixir developers building applications that need to generate or process email, such as web apps with notification systems, mailing list tools, or email client backends.
Developers choose Mail for its composable, functional API that aligns with Elixir conventions, its strict RFC2822 compliance ensuring interoperability, and its bidirectional capabilities for both building and parsing emails.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Allows chaining functions like `put_text` and `put_html` to build emails step-by-step, aligning with Elixir's functional programming patterns for predictable, immutable construction.
Ensures generated emails adhere to the official internet message format standard, preventing format errors and ensuring interoperability with other email systems.
Supports creating emails with text, HTML alternatives, and attachments using functions like `put_attachment`, as demonstrated in the README examples for complex messages.
Can both build new messages from scratch and parse existing RFC2822 messages back into structured Mail.Message data, useful for handling incoming email or debugging.
Mail focuses solely on message construction and parsing, lacking functionality to send emails via SMTP or other protocols, which requires additional libraries or manual integration.
Does not include advanced templating engines or dynamic data binding; developers must manually construct email content using Elixir code, which can be verbose for complex templates.
The README is brief and primarily points to external docs, which may not cover all edge cases or provide extensive tutorials, potentially increasing the learning curve for beginners.
