Layout: A clear, logical layout helps guide the reader's eye to the most important information. Use grids and whitespace effectively to avoid clutter. Typography: Choose fonts that are readable and reflect your brand's personality. Avoid using too many different fonts in one email. Color Scheme: Use a consistent color palette that aligns with your brand. Colors can evoke emotions and influence behavior, so choose wisely. Images and Graphics: High-quality images and graphics can make your email more engaging. However, ensure they don't overshadow the content or slow down load times. Call to Action (CTA): Your CTA buttons should stand out and be easy to find. Use contrasting colors and compelling text to drive action.
