In this episode of Let's Talk Email, Steven and Jay dive into the visual side of email development: Image Optimization and Video. We tackle the age-old debate of file size limits—how big is too big for a GIF? We also explore the frontier of video in the inbox, discussing everything from the "MP4-as-an-image" hack for Apple Mail to the enterprise-level solutions like Playable and EyeMail. Plus, we take a trip down memory lane to discuss the "dark arts" of pixel art and CSS-only gradients in tables.

Key topics covered:

• Baseline Best Practices: Why we aim for 100kb–200kb for statics and the 3MB sweet spot for GIFs.
• The Tools of the Trade: How to get the most out of Photoshop's "Save for Web (Legacy)," EZGIF, and TinyPNG.
• Video in Email Demystified: The server-side nightmare of hosting video and why a GIF with a play button is still the industry standard.
• The "MP4 Hack": How to use the picture element to serve high-quality silent video to Apple users.
• Accessibility & Motion: Managing "cognitive load" and why animating all 9 products in a grid is a bad idea.
• Retro Email Dev: A look back at images and gradients made from tables for when images were blocked.
