Desktop Email Preview Tool
While mobile is growing, many B2B and corporate users still engage with emails on desktop. Test your wide-screen layouts and Outlook-specific rendering here.
📖 How to Optimize for Desktop
Monitor Width
Standard desktop emails should be capped at 600px - 650px wide to ensure they don't look stretched on ultra-wide monitors.
Longer Subjects
Desktop clients allow for longer subject lines (up to 60+ chars). Use this extra space to add more context or urgency.
Verify Images
High-resolution screens can make low-quality images look blurry. Use 2x sized images for Retina desktop displays.
Outlook Check
Desktop Outlook often ignores background images. Always set a fallback background color for your main containers.
💡 Desktop Rendering Nuances
Previewing on desktop is about more than just screen size; it's about the environment. Desktop users often have multiple windows open, meaning your email is competing for high-level cognitive attention.
- Typography: Ensure your line-height is at least 1.5x on desktop to prevent text from looking cramped on large screens.
- The Sidebar: Most desktop clients (like Outlook or Apple Mail) have a sidebar. Our 100% width preview simulates how your email adapts if the user resizes their preview pane.
- Hover States: Unlike mobile, desktop users can hover over links. Test your button hover effects to add a layer of interactivity.
- Loading: Desktop users usually have faster connections, but that shouldn't be an excuse for unoptimized HTML. Keep your file size under 102KB to avoid Gmail clipping.
