1. Why "F2 Conversion" Influences Value Chain of Mall Operation
Trap many EC businesses fall into is deterioration of ROI due to "new acquisition supremacy". Cohort analysis reveals reality that more than 80% of customers acquired by spending advertising costs leave without purchasing second time. It is statistically significant that customers who succeed in F2 conversion (raising from first to second time) have dramatically higher continuation rate to F3 and F4 thereafter. In other words, F2 conversion is not just repeat measure, but leverage point that changes profitability of entire business.
2. Optimization of Step Emails Reverse-Calculated from Purchase Cycle and Cohort Analysis
Basis of CRM is "delivering message to appropriate segment at appropriate timing". For example, for customer who purchased 30-day supplement, scenario design to automatically deliver follow-up email with coupon around 25th day just before consumption is required. This is "anticipating demand", not "resolving deficiency". Personalized approach that does not damage brand experience accelerates F2 conversion.
3. Synchronization of Point Ecosystem Specific to Rakuten/Yahoo and CRM Measures
Malls have powerful purchase incentives such as Rakuten's "Shopping Marathon" and Yahoo!'s "Days ending with 5". By synchronizing own CRM scenario with these events and sending reminders according to point-up period, maximization of close rate conscious of attribution can be aimed. Strategic promotion using mall's "buying time" not purely for company's convenience is necessary.
