In this episode of Let's Talk Email, Steven and Jay dive into the visual side of email development: Image Optimization and Video.

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.
