Improving contrast in your emails can be straightforward if you follow these best practices:
Color Schemes: Choose color schemes with high contrast. Tools like contrast checkers can help you determine if your choices are optimal. Font Size and Weight: Use larger font sizes and bold text to improve readability. Button Design: Make sure buttons stand out by using contrasting colors and clear, bold text. Backgrounds: If using images as backgrounds, apply a slight overlay or shadow to make the text stand out.
