Wake the sleeping cashback
Run a targeted reactivation blast to the 15,251 lapsed members who earned ₱3.11M lifetime with the program (bXTRA Account ledger check: mostly already redeemed — so the hook is history, not waiting money): "You've earned with Trash to Cashback before. Bring recyclables to [nearest Mandaluyong point] and start earning again." Drive them via SMS / app push / the bXtra-lookup page, prioritizing Mandaluyong and NCR.
Why it works: zero acquisition cost — these people already know the program and have a balance. Deposit-return evidence (Germany >98% return) shows a clear, owed, personal value is the strongest participation trigger. Even a 15% reactivation = ~2,300 members returning.
