It's time to design your email

Preview sample — scroll down to verify iframe scroll works

Hello, subscriber 👋

This is a demo preview rendered inside the mc-preview-modal component. It is isolated from the app shell by a sandboxed iframe, so its CSS and fonts cannot leak into Acelle.

Use the device toggle above to switch between desktop, tablet, and mobile framing. The chrome morphs in/out with a smooth animation — browser dots for desktop/tablet, phone chassis for mobile.

✨ Try the device toggle

Click the icons in the toolbar to see the modal transform. The iframe keeps rendering without a reload — only the chassis changes.

Why in-app preview?

Opening a preview in a new tab breaks the in-app flow. You lose your scroll position, your filters reset, and context-switching feels slow. A modal keeps you in place while letting you inspect the full template.

🚀

Fast switching

Keep the preview open, switch templates — iframe reloads, chrome stays put.

🎨

Authentic rendering

Sandboxed iframe = same isolation as a new tab. What you see is what subscribers get.
