EscuelaSM
Paid ads case study: EscuelaSM reversed a sales slump by implementing Darwin AI and ad optimization, reaching 43 monthly course sales — its all-time record.
The challenge
During the final months of 2025, EscuelaSM faced a sharp decline in course sales. November 2025 saw 29 courses sold, and December dropped to just 18 courses.
There was also a critical operational issue: many leads were going unattended, directly impacting sales closures. The average cost per initiated message held at $1.72, a level that didn't allow efficient lead volume scaling.
Goal
- Reduce Cost per Initiated Message to maximize lead volume
- Optimize lead management and response using Darwin AI
- Increase the number of courses sold monthly
The strategy
We implemented an integrated strategy combining AI technology with advertising optimization:
1. Darwin AI
Implemented to efficiently manage and respond to the high volume of leads, solving the unattended lead problem.
2. Audience segmentation adjustments
Audience refinement to improve traffic quality.
3. Conversion-focused creative adaptations
Creatives designed specifically to generate immediate action.
4. Urgency and scarcity strategies
To accelerate course closures.
5. Continuous optimization
Based on performance data and lead behavior.
