Why WhatsApp wins for flash sales
Email and SMS arrive minutes-to-hours late — by the time a customer checks, the sale is over. WhatsApp delivery is instant, push-notified, and 98% opened.
Run a 3-pulse loop: T-0 launch, T+12h mid-sale (excludes converters), T-2h last-call (excludes converters). Wire Shopify's out-of-stock webhook so the broadcast halts the moment inventory hits zero.
Gate the drop to your top 20% RFM cohort 6 hours before the public send — they convert harder and feel rewarded, lifting LTV.
