**Day 7 Callback Request: High-Value Signal, But Still Below Upgrade Threshold** - **Behavior = buying intent, not just browsing.** A callback request is an explicit "I want to talk" action — strongest intent signal short of a proposal request. *中文：主动预约回电属于明确的购买意向，比浏览、看视频等被动行为强得多，是最接近“要谈生意”的信号。* - **Score jumped 10 → 19, but threshold is 60.** The behavior is high-value but frequency and depth (e.g., multi-stakeholder visits, proposal views) are still low, so AI correctly holds in C. *中文：分数虽从10升到19，但离C→B的60分门槛仍远；行为价值高，但互动频次和深度不足，AI维持C池是合理的。* - **Trigger: high-priority sales follow-up within 24h + send tailored B2B proposal.** Callback requests should auto-route to a rep with context (course interests, past views) to convert momentum into a meeting. *中文：系统应在24小时内触发高优先级销售跟进，并推送定制化B2B方案；把回电请求自动派给销售，附上客户兴趣和浏览记录，趁热打铁约会议。* - **For a 100-unit distribution inquiry: treat as deal-qualification step, not a nurture step.** Route to enterprise/channel sales, confirm volume, delivery format, and budget — this is pipeline acceleration, not drip marketing. *中文：若目标是100套分销询盘，这应走大客户/渠道销售流程，重点确认采购规模、交付方式和预算，属于加速成单，而非普通培育。* - **Business outcome:** Rep follow-up today + proposal in 48h can push score past 60 → auto-upgrade C→B → unlock larger deal motion, improving conversion rate and shortening sales cycle. *中文：今天回电+48小时内出方案，有望把分数推过60，自动升级到B池，解锁更大商机动作，从而提升转化率、缩短销售周期。*
