Most popup builders call their popups "responsive" and technically, they are.
But responsive doesn't always mean you have control over what happens on mobile. Close buttons end up off-screen. Columns don't stack right. Form fields scale past the point of usability.
That's why we built Mobile Popup Design.
With Mobile Popup Design, you can:
Style your desktop and mobile layouts independently inside a single campaign
Show or hide any block per device with a single click
Preview every device view in real-time before you publish
We've written a short post explaining how it works and what you can do with it right away.
