- Use a single-column layout: This ensures that your content stacks vertically and is easier to read on smaller screens. - Keep it simple: Less is more when it comes to mobile email design. Focus on key messages and use concise text. - Optimize images: Compress images to reduce load times, and use the `alt` attribute for image descriptions. - Avoid using too many links: Too many links can make your email look cluttered and be difficult to interact with on smaller screens.
