The Rarest and Coolest Defensive Design Tactic: Email Pixel Art

Email Pixel ArtImage blocking is common, with some email clients disabling images by default and some subscribers turning off images to save mobile data or for other reasons. Because of that, email marketers need to use defensive design techniques to ensure that their message is conveyed when images are disabled.

Defensive design consists of three key tactics:

  1. Using HTML or live text as much as feasibly possible, instead of embedding all of your text into your images
  2. Adding ALT text to your images—or better yet, styled ALT text
  3. Using background colors on table cells

Let’s focus on that last tactic. Adding a background color to a table cell creates banners, content blocks, and is essential to making bulletproof buttons.

That’s great, but background-colored table cells can do more—much more. In addition to being used along with HTML text to create email content that is unaffected by having images blocked, table cell background colors can be used as a fallback for images. You do this by creating an email mosaic out of table cells and placing it behind an image. When the overlaying image is blocked and disappears, then the underlying email pixel art appears.
