WHY I LOVE THE CONSTRAINTS OF EMAIL

Summary from the TLDR Marketing newsletter

Email's power comes from its constraints. A narrow 600px layout, outdated HTML, and unpredictable rendering force focus on clarity, strong copy, and intentional design instead of flashy features. These limits reduce decision fatigue and spark creativity, pushing marketers to prioritize the most important message. With fewer distractions and a defined structure, emails deliver higher ROI and conversions than more technically capable channels.
