Design one single mobile app icon for the App Type, presented exactly like a real App Store or Google Play icon. Use the Icon Concept as one bold, centered symbol with a strong silhouette, comfortable padding, crisp edges and smart negative space so it reads instantly at small sizes. Render it in the Icon Style using the Color Palette with strong contrast between the symbol and the icon background. Keep the design simple and iconographic, never a detailed scene or illustration. Place the icon inside an iOS-style rounded-square squircle with smooth corners, centered on a plain very light neutral background. The icon should fill about 70 percent of the square 1:1 canvas and cast a soft, subtle shadow beneath it. Show no device, hands, mockup, extra objects, text outside the icon, watermarks, thin hairlines, tiny details, sparkles, glow, lens flares or photographic textures. Do not copy or resemble any existing app icon, brand logo or famous mascot.
Use these details:
App Type: "Email marketing app"
Icon Concept: "An envelope whose open flap forms a megaphone"
Icon Style: "Flat bold icon with crisp geometric shapes"
Color Palette: "Red and cream"
