The "Experimentation" Engine: 1,000 Daily Emails for A/B Testing

Green.earth was already running cold email campaigns, but they were disjointed. They had multiple team members running parallel campaigns with no central infrastructure.

They wanted to rigorously A/B test different value propositions, subject lines, and offers. But they lacked the system to do this scientifically and at scale. They needed a controlled environment—a "lab"—to iterate fast.

Instead of outsourcing the sending, we built them a robust In-House Infrastructure capable of sending 1,000 emails per day safely.

This wasn't just about volume; it was about control. We set up:

• 20+ Dedicated Inboxes: Distributed across multiple domains to isolate tests.
• Centralized Dashboard: Providing a single view of all A/B test results.
• Standardized Workflows: Ensuring every test followed the same rigor for valid data comparison.

With the new system, Green.earth transformed from "guessing" to "knowing."

They now have a dial they can turn. When a message wins, they can immediately scale it across the entire 1,000/day capacity.
