An advertiser wants to preview its Collections ad. How can the advertiser do this?

The correct method to preview a Collections ad is by using the Pinterest Ads Manager. Within Ads Manager, advertisers can access a preview function that allows them to see how their ad will appear to users. This preview can then be viewed on a mobile device, which is crucial for Collections ads since they are primarily designed for mobile experiences. Exporting the Pin as an MP4 file is incorrect because Collections ads are interactive and not simply video files; an MP4 wouldn't capture the full experience. Creating a mock and editing it into a Pinterest grid is a manual, unofficial method that doesn't accurately reflect the ad's functionality within the platform. Launching the campaign and waiting to see the ad in the feed is inefficient and risks spending budget on an ad that might not display correctly or optimally.
