- **Day 7 callback request is a buying signal, not just engagement.** It shifts from passive content consumption to explicit intent to talk to a human — the strongest predictor of near-term conversion. - 第7天主动要求回电，是从“看内容”升级为“要和人谈”，属于明确的购买信号，短期成交概率最高。 - **Score jump (54 → 72) crosses the 60 threshold, triggering C → B upgrade.** AI isn't reacting to one click; it weights cumulative behavior plus the high-value callback event, so the upgrade reflects real pipeline quality, not noise. - 分数从54跳到72、越过60阈值，系统自动将客户从C池升级到B池；这是累积行为加高价值事件共同作用的结果，而非单次点击。 - **Triggered actions should be precise: route a success-team callback within 24h, send a tailored B2B proposal, and create a sales follow-up task with the lead's context.** No generic drip — the callback is time-sensitive. - 应触发精确动作：24小时内安排成功团队回电、发送定制化B2B方案、创建带上下文的销售跟进任务；不要用通用邮件流，回电有时效性。 - **This sets up the 100-unit distribution inquiry.** B-pool status + a live callback conversation lets sales qualify budget, scope and decision timeline early — positioning a 100-seat distribution proposal rather than a small pilot. - 这为100套分销询盘铺路：B池身份加实时回电，让销售能尽早确认预算、范围和决策周期，直接推100套分销方案而非小规模试用。 - **Business outcome: higher pipeline quality and sales efficiency.** The score (72 vs 120 for A) shows room to grow; continued nurturing keeps the deal warm until it's A-ready. - 业务结果：提升商机质量与销售效率；72分离A池120分还有空间，持续培育可保持商机热度直至具备A池条件。
