Images play a vital role in email marketing, but using the wrong format can affect your email’s performance. The recommended formats include:
JPEG: Ideal for photographs and images with many colors. JPEG files are compressed, which helps in reducing file size. PNG: Best for images with transparent backgrounds and graphics. PNG files offer higher quality but are usually larger in size compared to JPEGs. GIF: Useful for simple animations. GIFs can engage your audience but should be used sparingly to avoid large file sizes.
