The campaign

A large-scale B2B cold email campaign for one of my clients. Over 6 months we sent almost 400k emails, ramping volume up gradually before running at full scale.

Built for deliverability

Open rates were mostly not tracked. Open tracking adds a tracking pixel to every email, and leaving it off helps deliverability, which matters most when sending at this volume.

The proof

10%reply rate
2.3Kpositive, interested replies

Across 6 months the campaign sent 392k emails and received 13k replies, a 10% reply rate. Over 2,000 of those replies were positive and interested.

Key takeaways

Ramping volume up gradually is what made full-scale sending sustainable for months.

Leaving open tracking off trades a vanity metric for better inbox placement.
