The Challenge
Poshmark was launching a seasonal shopping campaign and needed to reach fashion-forward consumers who valued sustainable, secondhand fashion. The challenge was finding creators who were authentically part of the thrifting and sustainable fashion community — not just mainstream fashion influencers.
Previous campaigns had used broad fashion creator lists, resulting in high CPMs and low engagement. The content felt inauthentic because the creators had no real connection to secondhand shopping or sustainable fashion values.
Poshmark needed to find creators who specifically mentioned thrifting, sustainable fashion, and secondhand shopping in their bios and content — the kind of granular targeting that traditional platforms could not deliver.

The Solution
Creator Lookup’s bio search functionality was the breakthrough. Poshmark’s team searched for creators whose bios contained phrases like “thrift haul,” “sustainable fashion,” “secondhand style,” and “vintage finds.” The platform returned creators who had built their entire identity around the values Poshmark represents.
The team also used follower-count filters to focus on micro-influencers (10K–100K followers) who had higher engagement rates and more trust with their audiences. Creator Lookup’s verified contact data meant no time was wasted on dead-end outreach.
Key Advantages
- ✓Bio search found creators mentioning thrifting and sustainable fashion
- ✓Micro-influencer focus (10K–100K) drove higher engagement
- ✓TikTok-specific filters targeted the platform with highest ROI potential
- ✓Verified emails eliminated bounced outreach and wasted time
“The difference was night and day. When creators genuinely love thrifting, their audience trusts every recommendation. Creator Lookup helped us find those authentic voices at a scale we couldn’t achieve manually.
