What Are Email Friendly CSS Properties?
Email-friendly CSS properties are those that are widely supported across various email clients and devices. Email clients like Outlook, Gmail, and Yahoo Mail have different levels of support for CSS, making it crucial to use properties that ensure your emails render correctly everywhere. Using the right CSS properties can significantly impact the effectiveness of your
email marketing campaigns.
Why Is It Important To Use Email Friendly CSS?
The importance of using email-friendly CSS cannot be overstated. Inconsistent rendering can lead to broken layouts, unreadable text, and a poor user experience. This can decrease engagement rates and negatively impact your campaign's performance. Following best practices helps maintain a consistent and professional appearance, which can increase
open rates and
click-through rates.
- Font-family: Use web-safe fonts like Arial, Helvetica, and Verdana.
- Font-size: Use relative units like em or percentages for scalability.
- Color: Hex codes and RGB values are widely supported.
- Background-color: This property is generally safe but avoid using background images as they are not universally supported.
- Padding and Margin: Use these properties for spacing elements, but test across different clients for consistency.
- Border: Simple borders are usually safe, but avoid complex styles.
- Positioning: Avoid using `position: absolute` or `position: fixed`.
- JavaScript: Most email clients do not support JavaScript for security reasons.
- External Stylesheets: Inline CSS is preferred as external stylesheets are often stripped out.
- Complex Selectors: Stick to simple selectors and avoid descendant selectors.
How To Ensure Compatibility?
Testing is crucial for ensuring compatibility. Use tools like Litmus or Email on Acid to test your email across multiple clients and devices. Additionally, always send test emails to yourself and colleagues to check for any issues before sending them to your entire
email list.
Inline CSS vs. Embedded CSS
Inline CSS is more reliable because it is directly applied to the elements, reducing the risk of it being stripped out by email clients. Embedded CSS (within `` tags) is less reliable but can be used for styles that will not be overridden.
Best Practices
- Use Tables for Layout: While tables are outdated for web design, they are still the most reliable way to create layouts in email.
- Use Alt Text for Images: Ensure that your images have alt text in case they do not load.
- Test Extensively: Always test your emails in various clients before sending them out.
- Keep It Simple: Simplicity ensures better compatibility and faster loading times.
Conclusion
Using email-friendly CSS properties is essential for creating effective email marketing campaigns. By understanding which properties are safe to use and which should be avoided, you can ensure that your emails look great across all clients. Always test extensively and follow best practices to maximize your campaign's success.
