Implementation of AI Next Best Action System for Marketing
Next Best Action (NBA) — system determining optimal next action for each customer at each moment. Not "what to offer" (product recommendation), but "what to do" — call, send discount email, show banner, connect manager or do nothing. Reinforcement Learning + business rules.
Contextual Bandit for NBA
NBA with RL shows ROAS 4-8x on marketing spend vs 2-3x on rule-based approach. Main insight: for ~30-40% customers optimal action is "do nothing" (save money). Not model error — correct decision. Excess communications increase churn.
