Premailer

What is this?

For the best HTML e-mail delivery results, CSS should be inline. This is a huge pain and a simple newsletter becomes un-managable very quickly. This script is our solution.

• CSS styles are converted to inline style attributes
  Checks style and link[rel=stylesheet] tags and preserves existing inline attributes
• Relative paths are converted to absolute paths
  Checks links in href, src and CSS url('')
• CSS properties are checked against e-mail client capabilities
  Based on the Email Standards Project’s guides
• A plain text version is created

A few things to note:

• Things can get messy very quickly with the * selector—be careful
• Only the screen, handheld and all media types are processed
