CSS Inliner Service - Email Marketing

What is a CSS Inliner Service?

A CSS Inliner Service is a tool that converts CSS styles from the head section of your email into inline styles. This process ensures that your email renders correctly across various email clients, many of which do not support external stylesheets or embedded styles within the head.

Why is Inlining CSS Important in Email Marketing?

In Email Marketing, ensuring your emails look consistent across different email clients is crucial. Many email clients strip out head styles or don't support them at all. By inlining CSS, you increase the likelihood that your email will look as intended, regardless of the platform or device it is viewed on.

How Does a CSS Inliner Service Work?

A CSS Inliner Service works by parsing your email's HTML and moving the styles from the head section into the HTML elements themselves. This involves converting all the CSS rules into inline styles, effectively embedding them directly within the HTML tags.

Benefits of Using CSS Inliner Services

Improved Deliverability: Reduces the likelihood of your email being marked as spam due to missing or broken styles.
