Design a multichannel satisfaction survey deployment for [ProductLine] targeting [TargetSegment] in [Region]. Recommend the optimal channel mix (email, in-app, SMS, QR at PoS, IVR) with send windows by local time. Define deliverability steps, throttling, and fatigue limits (max touches/[Timeframe]). Create an A/B/C plan for subject lines and CTAs tailored to [BuyerRole] personas. Include preheaders, sender identities, and fallbacks for hard bounces. Outline tracking (UTM, per-channel completion rate) and quota management to reach [SampleSize] completes without skew.
Output format: 1) Deployment Calendar (table: date, channel, audience, volume, goal). 2) Experiment Matrix (variant, hypothesis, success metric [PrimaryMetric], sample allocation, stop rule). 3) Fatigue Policy (bulleted). 4) Channel-specific Copy Blocks (short).
