Winback Engine
Turn dormant subscribers back into customers. This skill scans your connected ESP for inactive subscribers, segments them by historical value, drafts a personalized winback series per tier, and flags who you should suppress before they tank your deliverability.
Requires: Cogny MCP + a connected ESP. Sign up
The output is a complete, ready-to-run winback campaign — not a report.
Usage
/winback-engine — standard mode (60-day dormancy threshold)
/winback-engine aggressive — 30-day threshold (acts earlier, bigger list)
/winback-engine conservative — 90-day threshold (only chronic dormants)
Prerequisites Check
Detect connected ESP (same pattern as subject-line-lab). If none, prompt user to connect at cogny.com.
