Recently, for a newsletter, I needed to fine-tune the HTML of an HTML Mail. At some point during my work I had to convert formatting based on an external stylesheet to inline styles.
I've used the free CSS Inliner Tool by Mailchimp.com for this task.
Some email clients strip out
<style>tags from emails, so it's best to have your CSS written inline within your markup. We know that writing inline CSS is time consuming and repetitive, so we've built this conversion tool to automatically inline your email's CSS.
It works very well.
But I wonder, if they decide to take this service offline, or start to charge for it, or change the functionality, what would be a good free alternative?
Can be another online service, or a desktop tool - command-line or GUI-based, I don't mind.
