Implementing background images in emails can be tricky due to inconsistent email client support. However, there are several methods to ensure your background images display correctly:
CSS Background Image: Use CSS to apply background images to elements. This method provides more control but may not be supported by all email clients. VML for Outlook: Outlook does not support CSS background images, so you need to use Vector Markup Language (VML) for compatibility. Fallback Colors: Always include a fallback color in case the background image doesn't load, ensuring readability.
