The Challenge
50,000 contacts in CRM — mix of lapsed clients, cold prospects, and legacy data. Couldn't send to them via main ESP without destroying deliverability. Data was too valuable to ignore but too risky to touch through existing infrastructure.
What We Did
- 1Activated dormant contacts via Fortitude Labs dedicated infrastructure
- 2Segmented by engagement history and recency
- 3Built tailored 3-step reactivation sequences per segment
- 4All re-engaged contacts passed back with engagement scoring
“The data activation use case was exactly what we needed. We had 50,000 dormant contacts we couldn't safely touch through our main platform. Fortitude Labs re-engaged 12% of them without touching our sender reputation.”
