A Ruby gem that automatically inlines CSS into HTML emails by converting linked stylesheets and style tags into inline style attributes. It integrates with ActionMailer as a delivery hook and also works without Rails.
Use cases
- style HTML emails with CSS that renders in Gmail and Outlook
- inline CSS into ActionMailer emails automatically
- keep email HTML and CSS in separate files
- make emails compatible with clients that ignore linked stylesheets
- use email CSS inlining in Sinatra without Rails
When to choose
- you send HTML emails from a Rails app and want zero-config CSS inlining
- you need emails to render correctly in clients that strip <style> tags
- you want to maintain email styles in separate stylesheets
When to avoid
- you send only plain-text emails
- you don't use Ruby
- you need full email template design tooling rather than CSS inlining
