Key Questions

What is the main gating factor for scaling cold email campaigns?

Sender reputation and infrastructure, including domains, DNS setup, warm-up processes, throttling, bounce rates under 2%, and domain health above 80%, remain the primary constraints. These factors directly impact deliverability rates. Nearly 20% of marketing emails fail to reach inboxes due to poor tracking and management.

Which tools achieve high email deliverability rates?

Tools like Warmforge, Instantly, and Sai deliver around 90% success rates. Salesforge MCP uses Claude for health monitoring and sequences, while LGM supports multichannel efforts. Sopro handles 126M emails with a focus on coverage over volume.

What ongoing efforts are improving deliverability?

Initiatives include 10k tests targeting key metrics, Sai's personalization and deliverability pilots, and alignment with new automated campaign basics. These address bounce rates and health thresholds. Strong ROI requires active management of returns from email campaigns.
