What is the best file size and format to add email banner animation?
Use GIF files to add animation to your email signature banner. For best performance, keep your banner GIF file size below 45kb by limiting the number of frames. We recommend 2-3 frames with 2-3 seconds between them and image resolution to 72dpi.
Simple animation such as changing product images or colour choices draws attention to your message.
Some email clients do not support animation and will display the GIF as a still image. Therefore feature your most important message on the first GIF frame so, even without animation, recipients will get your main message.
We recommend that if you’re planning to use an animated .GIF that this only has one clickable link, and does not use image maps at the same time.
