    To maximize email loading speed, selecting the right image formats and sizes is crucial. When choosing between JPG, PNG, and GIF for email images, opt for JPG for photographs, PNG for transparent graphics or icons, and reserve GIFs for simple animations. Resize images to their actual display width (around 600-700 pixels for a single-column email) before uploading to prevent unnecessary weight. Compress images to keep individual files under 200 KB and aim for a total email weight under 1 MB. Utilize tools like Adobe Photoshop’s “Save for Web (Legacy)” or online options like TinyPNG, Squoosh, or ImageOptim for effective image optimization without compromising quality.
