# Reactivating Hibernating Users via Email or WhatsApp

**Reactivating Hibernating Users via Email or WhatsApp**

**Trigger**\
Users haven’t engaged (logged in, opened email, used product) in the last 45 days. Segment: "Hibernating".

**Action Flow Options**\
Co-Pilot randomly selects and tracks the effectiveness of different actions:

* Email with a reactivation incentive (e.g. discount or reminder of benefits)
* WhatsApp message offering a quick survey or support touchpoint
* Wait step with no action (control group)
* Push notification (if app installed)

 **Co-Pilot Exploration**\
Initially rotates actions randomly → learns which actions lead to higher reactivation or prevent churn → prioritizes top-performing action for future users.

 **Next-Best-Action Push**\
Winning action is pushed to CRM or marketing tool (e.g. Customer.io, Klaviyo, HubSpot) with:

* Personalized content (based on segment or RFV score)
* Time of day optimization (based on user past engagement)
* Channel preference routing (email vs WhatsApp)

 **KPIs Tracked**

* Reactivation rate (re-engagement within 7 days)
* Open/Click-through rate per channel
* Conversion or purchase post-reactivation
* Long-term retention lift
