Telegram Number Screening Pitfall Avoidance Guide: Core Logic for Precisely Targeting High-Value Customers

Cross-Border E-Commerce Telegram Marketing: Customized Number Screening Paths to Target Your AudienceThe root cause of high costs in cross-border marketing lies in "resource mismatch"—investing budgets and energy in ineffective accounts. WhatsApp account screening is key to solving this resource mismatch.

By using ITG's full-domain filtering, enterprises can efficiently eliminate invalid numbers and focus on high-value customers, achieving a triple optimization of "reduced push costs, improved manpower efficiency, and saved opportunity costs".In today's increasingly competitive cross-border marketing environment, "cost control" is just as important as "effectiveness improvement".
