Inlines styles from <style> tags directly into HTML elements, as shown in the README's input/output example, ensuring better compatibility across email clients like Gmail and Outlook.
Includes a TransformText method to generate plain text versions of HTML emails, useful for accessibility and fallback content, demonstrated in the example code.
Provides a CLI tool for processing HTML files from the terminal, making it easy to integrate into automation scripts or CI/CD pipelines, as mentioned in the commandline section.
As a Go library, it has a simple API with few dependencies, following the Unix philosophy for easy addition to Go email pipelines, per the installation and example snippets.
The library focuses on basic CSS inlining and may not handle advanced features like media queries or vendor-specific hacks crucial for complex email templates, with no mention in the README.
The README is brief with minimal examples, lacking detailed guides on edge cases or troubleshooting email client quirks, which could hinder adoption for nuanced use cases.
Being written in Go, it cannot be used in projects based on other programming languages, limiting its utility in mixed-technology environments.
