The Objective
Three goals, one campaign
Stella Rosa set out to accomplish something most brands pursue separately: drive web traffic, spark instant-win engagement, and grow a high-quality first-party email database — all at once.
01
Web Traffic
Drive high-volume, qualified visitors to the campaign entry page.
02
Instant-Win Engagement
Create urgency and delight with an immediate-result mechanic.
03
Email List Growth
Capture high-quality opt-ins to build a brand-owned marketing channel.
The Strategy
A prize everyone actually wants
Stella Rosa launched the $100K in Groceries Sweepstakes — an instant-win promotion built around everyday consumer motivation. Groceries aren't aspirational, they're essential, making the prize relevant to virtually any household.
"Enter now for a chance to win instantly."
The instant-win mechanic was critical. Participants found out immediately if they'd won — no waiting, no doubt. That immediacy created genuine urgency, boosted completion rates, and made the experience shareable.
Promotion & Media
Audio reach, at scale
The sweepstakes ran across a powerful mix of audio and digital channels — combining mass awareness with targeted precision to drive audiences directly to the entry page at peak interest.

401,900Total campaign entries
385KNew email opt-ins
The near one-to-one ratio of entries to email opt-ins is the real story here: participants didn't just want to win — they wanted to hear from Stella Rosa. That's a sign the incentive, UX, and brand trust all aligned perfectly.
Why It Worked
Four factors behind the performance
No single element made this campaign succeed. It was the combination of the right prize, mechanic, distribution, and user experience — all working together.
Stella Rosa walked away with significant email list growth, a surge in web traffic, and measurable direct consumer engagement. But the longer-term value is what that data enables: a direct-to-consumer marketing channel the brand now owns outright — no algorithm, no third-party dependency.
High-volume first-party data acquisition, done right, is one of the most durable assets a brand can build. This campaign showed exactly how to do it.
