Researched

Historical customers researched overnight

Mizzen+Main, the performance menswear brand, needed a way to reach high-value executive buyers who had purchased in the past but weren't responding to broad-based campaigns. Traditional segmentation fell short — they needed richer signals about who their best customers really were.

Using OuterSignal, they researched over 100,000 historical customer records overnight, uncovering detailed professional and lifestyle attributes. They built a "C-Suite Executive" audience and activated it on Meta Ads — resulting in their highest-performing campaign in company history, with over 20x ROAS and a $50 AOV lift over baseline.

Case Study

Gratsi: Persona-Based Email Personalization

Gratsi, the direct-to-consumer Italian wine brand, ran a controlled A/B test to measure the impact of OuterSignal's persona intelligence on email marketing performance. A single campaign was split between a generic control and persona-matched creative variants — same timing, same audience size, different messaging.

Key Takeaway

In this campaign, subject lines were kept the same but each persona group received a specific email. Open rates were virtually identical between control and personalized variants (+0.2%), proving that the audiences were consistent. As such, the lift came entirely from higher click-through and conversion, not from deliverability or subject line differences. When your customers see themselves in the message, they act.

Case Study

How Magic Mind earned a $0 Kim Kardashian Instagram story.

After using OuterSignal for one week, Magic Mind discovered Kim Kardashian was already a customer. VIP detection revealed she'd been buying the product organically for nearly two years, with no partnership in place.

With that knowledge, the Magic Mind team sent a thoughtful care package. She then posted the product to her Instagram story, reaching an audience of hundreds of millions. Sponsored posts from Kim Kardashian's account typically cost in the millions of dollars. Magic Mind earned it organically, by recognizing the human behind an order.

Every serious e-commerce brand has VIPs like this hidden in their order data. OuterSignal finds them in week one.

Case Study

Jolie's Top-selling Meta Audience?
Built on OuterSignal.

Jolie, the beauty wellness company, wanted to know if a custom lookalike built from OuterSignal customer intelligence could outperform their existing Meta Ads audiences. Over three months, they tested it head-to-head against their full set of broad, interest, and lookalike audiences. The OuterSignal audience led the set on sales, efficiency, and conversion rate.

+412%

Sales Lift

More sales than the average of Jolie’s other Meta audiences over the 3-month test.

+379%

Spend Lift

Jolie kept pouring more budget in because it kept working.

32%

Lower CPA

Cheaper cost per acquisition than the average peer audience, even as spend scaled.

+90%

Conversion Lift

February conversion rate lift over the rest of the set. The trend kept accelerating into March.

Core Takeaway

Compared to the average of Jolie's other Meta audiences, OuterSignal drove 379% more spend, 412% more sales, and a 32% lower CPA. Scaling campaigns usually means giving up efficiency. Here, Jolie got both.
