  • All supplied ads require both the creative and clickthrough URL.
  • Must be supplied as a standard image format (.jpg, .gif, .png) only.
  • Static .gif files are recommended over animated as Outlook does not animate images.
  • Email clients that don’t support animation only show the first frame of the image, so ensure the first frame contains the desired key messaging.
  • Maximum animation length of 15 seconds.
  • Cannot be third-party served, but can be click-tracked.
