mailchimp's CSS Inliner - Email Marketing

What is Mailchimp's CSS Inliner?

Mailchimp's CSS Inliner is a tool that helps convert your embedded or external CSS into inline CSS. This is particularly important in email marketing because many email clients strip out or ignore external CSS, leading to rendering issues. By inlining CSS, you ensure that your email looks consistent across different email clients.

Why Use Inline CSS in Email Marketing?

Inline CSS is crucial for email design as it ensures compatibility across various email clients. Some email clients, like Gmail and Outlook, have limited support for embedded or external stylesheets. Using inline CSS ensures that your email's styling is preserved, making your content more readable and visually appealing.

How Does Mailchimp's CSS Inliner Work?

Mailchimp's CSS Inliner automatically scans your email's HTML for embedded or external CSS and converts them into inline styles. This process happens when you import your HTML template into Mailchimp or when you use their design tools. The inliner takes away the manual effort of converting CSS, allowing you to focus on creating engaging content.
