This email ran the risk of being pretty text-heavy, so my first priority was to balance out the weight of the copy with imagery and plenty of white space. Wanting to try a 2-column layout for the content, the email mimics the layout of the parent website (at the time of development).
Background images with Outlook (non-retina) variants used for the logo block, hero section, and both offer images. Mobile-specific images replace the background images for both offers, switching from a vertical to horizontal orientation.
