Case Study: SendtoWin achieves 35% higher positive reply rates with Apollo

How One Agency Achieves 35% Better Reply Rates

SendtoWin is a lead generation and outbound agency that manages campaigns for hundreds of clients across 60+ industries. As their outreach scaled, they faced major challenges with manual research, incomplete data, and invalid contacts that made personalization harder and reduced campaign efficiency. They turned to Apollo for data enrichment and outbound campaign support.

Using Apollo’s data platform and AI Research, SendtoWin built more precise target lists, enriched external data, and uncovered deeper prospect signals for hyper-personalized outreach. The results included 30–40% more enrichment coverage, 25–35% higher positive reply rates, and a 2% email-to-win rate on targeted campaigns. Apollo also helped them save time and improve outreach at scale.
