These screenshots of the revised CQ email alerts look pretty basic, and it’s completely on purpose. The old emails each had a completely different look, were very complex table-based designs, and were not at all responsive (mostly because when they were made the flip phone was just becoming popular.)
The goal with the new design was to have a great mobile reading experience as well as a consistent brand look. But it was also important that there be enough visual difference that you could easily tell them apart at first glance. The designs are kept minimal for both super-fast loading times and readable content even if images or styles were blocked by the server or email client. You’ll also notice there’s a lot of content in each email — yet another reason to keep the design lean.
