Success can be measured through several KPIs: customer retention rate (retention), Customer Lifetime Value (CLV), Net Promoter Score (NPS), repeat purchase rate, and cross-selling rate. AutoLetter offers integrated tracking functions with personalized QR codes and landing pages. Additionally, we recommend control group tests where a portion of customers don't receive care letters – so you can measure the incremental effect exactly.
Effective personalization goes far beyond the salutation. Use purchase history, product preferences, usage behavior, life stages, and interaction history for multi-dimensional personalization. AutoLetter enables automatic assembly of modular text blocks based on customer data – creating individually composed letters that feel handwritten.
Direct mail achieves its strongest impact in combination with digital channels.
