What is Mailchimp’s CSS Inliner?
Mailchimp’s CSS Inliner is a tool that automatically converts your
CSS styles from the
style block in the head of your HTML email to inline styles. This is crucial for ensuring that your email renders correctly across different email clients, many of which do not support styles in the head section.
Why is CSS Inlining Important?
Many email clients strip out the head section of HTML emails, which means any CSS placed there will not be applied. Inline CSS, on the other hand, is widely supported. Using a CSS inliner ensures that your email's design remains intact when it reaches your subscribers, providing a consistent and professional appearance.
How Does Mailchimp’s CSS Inliner Work?
The CSS Inliner works by analyzing the styles defined in the head and applying them directly to the relevant HTML tags as inline styles. For example, if you have a `` element in your head that targets a class `.button`, the Inliner will find all elements with that class and add the styles directly to each element.
Benefits of Using Mailchimp’s CSS Inliner
Consistency: Ensures your email looks the same across all email clients.
Efficiency: Saves time by automating the inlining process.
Reliability: Reduces the risk of design issues caused by email clients stripping styles.
How to Use Mailchimp’s CSS Inliner
Using Mailchimp’s CSS Inliner is straightforward. When you create an email in Mailchimp, the platform automatically processes your email and inlines the CSS. If you're coding your email outside of Mailchimp, you can use their standalone
CSS Inliner tool available on their website.
FAQs about Mailchimp’s CSS Inliner
Can I still use external stylesheets?
External stylesheets are generally not recommended for email marketing because many email clients do not support them. Mailchimp’s CSS Inliner is designed to handle inline styles, which are more reliable for email delivery. What types of CSS styles can be inlined?
Most common CSS properties can be inlined, including
font styles,
colors,
margins, and
padding. However, advanced CSS like media queries and pseudo-classes may not be fully supported.
Does the CSS Inliner affect the email's load time?
No, inlining CSS does not significantly affect the load time of your emails. In fact, it can improve load times because the styles are applied directly to the elements, reducing the need for additional parsing by the email client.
Best Practices for Using CSS Inliner
Keep it simple: Stick to basic CSS properties for maximum compatibility.
Test your emails: Always send test emails to different email clients to ensure your design renders correctly.
Use responsive design: Combine inline styles with responsive design techniques to ensure your email looks good on all devices.
