RankBoost Digital: $1.7M Pipeline in 90 Days Through Cold Email
Published January 18, 2024

The Challenge
RankBoost Digital, an SEO agency serving e-commerce brands, had plateaued at $50K monthly recurring revenue. Their inbound marketing was inconsistent, and they lacked a systematic outbound process. They needed to scale their client acquisition to reach their $200K MRR goal.
Our Solution
We built a targeted outbound engine focused on e-commerce directors at companies doing $5M-50M in annual revenue. Our strategy combined personalized cold email with strategic podcast guest placements to build authority. We created case study-driven email sequences showcasing their ROI with similar clients.
The Results
“Working with Mumbo Leads was a game-changer. They did not just send cold emails - they built us a complete outbound system. The podcast placement strategy alone has been worth 10x our investment.”
