Case Study: Sendoso achieves 78%+ open rates and 3.2x more replies with Amplemarket

How Sendoso reclaimed pipeline with Amplemarket 3.2x replies and under 3% bounces

Sendoso, a leading corporate gifting and direct mail platform, needed a better way to support its BDR team’s outbound motion. Before working with **Amplemarket**, reps were juggling enrichment, engagement, and signal tools across multiple systems, which slowed them down, made onboarding harder, and hurt pipeline performance.

**Amplemarket** gave Sendoso a single platform for signal-based outreach, AI-powered prospect research, personalized multichannel sequences, and workflow automation through Duo Copilot. After returning to Amplemarket, Sendoso saw inbox placement and reply rates rebound, with **78%+ open rates**, **3.2x more replies**, and **under 3% bounce rates** on AI-recommended leads.
