Optimizing JPEG images ensures that your emails load quickly and look professional. Here are some tips to achieve that:
Compression: Use tools like Adobe Photoshop or online services to compress your JPEG images without losing significant quality. Resolution: Keep the resolution appropriate for screen display, generally 72 DPI (Dots Per Inch). Dimensions: Ensure that the image dimensions fit well within the layout of your email. Oversized images can cause slow loading times and may not display correctly.
