Even though some amount of loss is inevitable, there are ways to mitigate its effects:
Optimize Images: Use the right balance of image compression to ensure that the file size is reduced without significantly affecting quality. Test Across Clients: Always test your emails across different email clients to ensure consistent rendering. Use Alt Text: Always include alt text for images so that even if an image is lost, the content is still accessible. Keep It Simple: Simplify your HTML and CSS to minimize the chances of rendering issues.
