1. Responsive Design: Use responsive email templates that automatically adjust to different screen sizes. 2. Single-Column Layout: Simplify your layout to a single column to avoid horizontal scrolling. 3. Clear and Concise Content: Use short paragraphs and bullet points to make your content easy to read on smaller screens. 4. Large Call-to-Action (CTA) Buttons: Ensure that CTA buttons are large enough to be easily tapped on a mobile device. 5. Optimized Images: Compress images to reduce load times and ensure they display correctly on mobile screens.
