Animated Gifs can bring some life in your email marketing campaigns. Since Mailster uses WordPress native methods to resize images, so they fit correctly and reduce file size, the animation is may lost during this process.
By default images you insert in your campaigns are resized which causes a loss of the animation. There is a plugin available to prevent this but you can also use a built in option in Mailster.
Use Original Image
Mailster has an option to use the original image instead of resizing it. You can find this option in the editbar if you select an image.
If you choose this option Mailster will use the original image which preserves the animation.
