Poshmark
3.8M TikTok views at $2.28 CPM with micro-influencers for Poshmark's summer campaign
Poshmark, a leading fashion resale marketplace, wanted to amplify its Summer Shopping Campaign through relatable TikTok creators who inspire style and secondhand sustainability.
With thousands of potential creators on TikTok, Poshmark needed a way to rapidly identify authentic fashion creators (10K–200K followers), prioritize engagement and average views over follower count, and launch at scale while keeping CPM below industry benchmarks. Traditional outreach tools were either too slow or too broad — manual vetting would have taken months.
Using CreatorLookup, we sourced and activated hundreds of fashion-focused micro-influencers to produce authentic, high-engagement TikTok content that drove awareness and conversions — all on a $8,750 total budget.
How we built it.
Mass Creator Discovery
We sourced 500+ TikTok fashion creators using platform filters for engagement rate, audience gender mix, and content themes. By combining AI-powered discovery with personal network vetting, we identified creators who authentically aligned with Poshmark's brand aesthetic.
Qualification & Outreach
Of the 500+ sourced, 185 creators expressed interest through direct outreach and automated verification. We prioritized creators whose existing content showed genuine enthusiasm for secondhand fashion and sustainable style.
Campaign Pacing & Optimization
We optimized campaign pacing and post timing to maximize reach within budget. The campaign went from concept to live content in under two weeks, with creators posting during peak engagement windows for fashion content.
The impact.
Micro-influencers delivered macro results. Smaller creators drove massive organic engagement at a fraction of typical CPMs, proving that authenticity converts better than reach.
Discovery speed was the competitive edge. CreatorLookup cut sourcing time from weeks to hours, letting Poshmark capitalize on seasonal momentum.
“CreatorLookup helped us find perfectly aligned TikTok creators who fit our brand aesthetic and compensation structure — and the results were incredible.”
