Why most companies get cold email marketing wrong
The Problem
Traditional email platforms weren’t built for outbound scale
Most email tools aren’t optimized for cold email at scale. When you push high-volume cold email blasts performance drops fast. Bounces increase, inbox placement declines, and provider restrictions kick in.
❌ Shared environments that punish volume spikes
❌ Low tolerance for bounces and list imperfections
❌ Limited control over sending behavior and infrastructure
❌ Weak visibility into what’s actually happening behind the scenes
