The situation

The company delivered corporate projects with high technical integration. The number of suitable accounts was limited and demand appeared only in specific windows.

In that environment, generic outreach could burn through the right companies before an actual project existed.

The approach

Protagnst replaced broad construction claims with a conversation about execution, integration and schedule risk. The client’s ability to deliver in as little as 25 days served as concrete evidence.

Segmentation favored precision. Technical emails reached leaders responsible for construction, expansion and infrastructure, while the cadence built recognition without assuming immediate demand.

The outcome

Average email open rate reached 57%, peaking at 73% in the strongest technical flow. The program identified 15 expressions of interest in a narrow account universe.

Because projects depended on timing, the pipeline was managed as a relationship. The source does not report meetings, proposals or contracts.

What this case demonstrates

In narrow markets, efficiency is not about sending more messages. It is about making every contact more relevant and preserving the right to a future conversation when demand appears.
