How previews work
When your agent makes an ad or a channel message, it stages the creative in one or more of the frames on this page: a paid social placement, or a WhatsApp or SMS thread. Each frame sets the aspect ratio, shows where the platform cuts the copy off, and knows which areas the platform's own interface covers. An email card previews the same way at full size, as the complete HTML your reader receives.
The frame only changes how you review the work. What ships is the media and the copy, unchanged. The sizes and copy limits come from each platform's ad specs and guide the preview: a creative in the wrong shape still saves, and shows letterboxed so you can spot it. Your agent writes the full copy, and the frame shows where it clips.
Every frame below stages the same sample campaign: The Lean Paper Airplane, the featured staff pick at P&P Bookstore, our demo brand. Ask your agent for a frame by the name on its tile.
On my "Summer sale" board in Plainpaper, make the summer reading creative as a vertical video staged in Instagram Reels. Keep text and logos clear of the areas Instagram's interface covers, and use a placeholder for the video until we have the cut.
