How a $15/Day Ad Strategy Generated 50 New Subscribers

When we started working together, the goal was clear: build a consistent, low-cost system to grow The Referral Edge’s newsletter audience and expand its reach among professionals in the services industry.

We began by running a small ad test — starting with just $10/day to identify winning creatives and targeting combinations. Within a few weeks, we found a high-performing ad set that was generating strong engagement and quality conversions. Once validated, we scaled it to $15/day while maintaining excellent cost-efficiency.

Over a 7-day period, the campaign generated:

50 new newsletter sign-ups, bringing the total subscriber base to 160+

5,000+ reach and 7,000+ impressions

$2.00 cost per conversion, an outstanding result for this niche

CTR and CPC outperforming benchmarks, with a $1.22 CPC and frequency stabilized at 1.2–1.3

All of this was achieved with a total spend of just over $100, proving that strategic optimization and clear audience alignment can outperform big-budget campaigns.

The purpose of this campaign was to grow a newsletter subscriber base that would later be monetized through exclusive offers and ad placements targeted to professionals. The result? A strong foundation for sustainable growth and new monetization opportunities — all from a lean, data-driven ad system.
