Optimize your GIF
GIFs are a great way to stand out in an inbox! However, not all email clients will display the animation. Instead, they will default to the first frame and show it as a single image.
The options for images will be shown for each GIF. You can select Play to view the new animation. To select your single default image, click on any frame in the animation, then click Apply.

Optimize Your Image Size
You will increase email engagement if subscribers don’t have to wait long for images to render; ideally, less than 2 seconds. We recommend keeping each image size under 200KB. This step detects the size of each image and offers the ability to compress each one. We offer free hosting of images on Amazon Web Services (AWS) and give you the ability to download your new optimized images on the summary page. If desired, this lets you replace large images with the compressed versions in a separate email editor.
A useful feature on this page is the email download map. To view the total email download time for each image in your email, click View Email Download Map . The map will render in the panel on the right. Click through the various sources to view the download time for each.
If your image is already optimized, you will see a green checkmark. If the images needs adjustments, you will see a yellow box with a warning sign. You can click Optimize All to fix all images at once, or click Optimize next to each image to fix one at a time.
