The "Master Source" Figma File: A clean, organized .fig file using Auto-Layout frames. This allows the client's internal team (or future freelancers) to change the text length without breaking the design structure.
The Component Library: I created a "Drag-and-Drop" asset page containing the buttons, product cards (like the iPhone and Blender cutouts), and headers as reusable components. This ensures brand consistency for future emails.
Optimized Image Slices: All complex graphics (the floating gadgets, the model with the laptop) were sliced and exported as high-res but web-optimized PNGs/JPGs (under 100kb) to ensure near-instant load times even on slow 4G networks.
Mobile & Desktop Mockups: A side-by-side visualization showing exactly how the layout stacks vertically on mobile versus the wide view on desktop.
