The Swipe File Gets an Upgrade
Ad teams have always kept swipe files. The practice is as old as advertising itself – collect what works, study the patterns, and build from there. What changed is the scale. Running paid social in 2024 means pulling inspiration from dozens of formats, platforms, and competitors simultaneously, and the old way of screenshotting ads into a folder stopped being functional a long time ago.
Milled built a loyal following by indexing email newsletters and making them searchable for marketers who wanted to see how brands structured their email campaigns. For a certain kind of researcher, it was invaluable. But ad teams working across Meta, TikTok, and YouTube needed something built specifically for paid creative – not newsletters, not organic posts, but actual running ads with context around performance and longevity.
Foreplay is the tool quietly absorbing that demand.
What Foreplay Actually Does Differently
Foreplay operates as a creative intelligence platform for paid media teams. At its core, it lets users save ads directly from Facebook’s Ad Library, TikTok’s Creative Center, and other sources into organized boards – functioning like a Pinterest for performance marketers. But the feature set goes well beyond bookmarking. Each saved ad retains metadata about how long it has been running, which is a proxy signal for whether it is actually converting, since brands rarely spend money keeping dead ads alive.
That longevity data is where Foreplay separates itself from generic inspiration tools. A brand manager or media buyer can filter saved ads by how long they have been active, essentially surfacing the ones most likely to be profitable for the advertiser running them. This lets creative teams reverse-engineer what is working in a given category without guessing. The logic is straightforward: an ad running for 90 days on Meta did not survive on luck. Something in that creative – the hook, the format, the offer framing – is generating return.
Foreplay also includes a brief builder, which connects the inspiration layer directly to the production layer. Creative briefs can be built from saved ad examples, pulling visual references and structural notes into a single document that goes directly to a designer or video editor. For in-house teams and agencies managing multiple clients, this cuts the back-and-forth that normally eats hours out of a creative sprint.
Why Milled Struggles to Compete in This Space
Milled’s strength has always been email. The platform indexes promotional emails from thousands of brands and makes them searchable by keyword, brand, or category. For email marketers and e-commerce teams thinking about their own newsletter strategy, that is genuinely useful. The interface is clean, the archive is deep, and the search functionality covers a lot of ground. It earned its reputation.
The problem is that paid social creative and email design are increasingly separate disciplines. A brand’s email creative team and its paid media team may share some visual assets, but their research processes are almost entirely different. A media buyer building a creative test for a Meta campaign does not typically start by searching email templates. They start by looking at what competitors are running in the feed, how long those ads have been live, and what angles the category has not yet exploited. Milled’s archive simply does not speak to that workflow.
Ad teams that once used Milled for broad competitive research are finding that Foreplay answers their specific questions faster. The shift is not about Milled failing – it is about Foreplay being purpose-built for a workflow that Milled was never designed to serve. Tools built around a specific professional context tend to win over tools that cover adjacent territory.
The Broader Pattern in Creative Research Tools
Foreplay’s rise fits a pattern playing out across the marketing software category, where general-purpose research tools are getting displaced by workflow-specific platforms. Boutique agencies are making similar moves in the social analytics space, choosing tools built around their exact reporting needs rather than enterprise platforms that require heavy configuration to get to the same place.
For Foreplay specifically, the timing is working in its favor. Creative testing has become more systematic as platforms have given advertisers better data on creative-level performance. Media buyers are now expected to think like creative directors, and creative directors are increasingly expected to understand what the data says. A tool that bridges those two roles – by connecting real-world ad examples to the brief-writing process – fills a gap that spreadsheets and shared Google Drive folders cannot.
The teams switching from Milled to Foreplay are not doing it out of frustration with email tools. They are doing it because their job descriptions changed, and their toolkits are catching up. When a paid social team’s primary output is video creative for Meta and TikTok, a searchable email archive stops being the right starting point – and an ad library with built-in longevity signals and brief-building functionality starts being the obvious one.
