Using Zalo, Vietnam's Most Popular Messaging App, for Digital Marketing

After global phone numbers are generated, a screening tool is used to extract "highly active, high-demand" users to avoid pushing content to "undemanding users" and causing resentment.

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".

Prioritizing WhatsApp account screening and using ITG's comprehensive filtering to build a precise and effective customer pool is crucial to maximizing the value of every marketing investment and achieving low-cost, high-efficiency growth in cross-border business.However, many companies overlook a crucial step: if they only generate global phone numbers without using number screening tools, a large number of invalid and risky numbers will directly trigger the platform's risk control, leading to the banning of marketing accounts and business interruption.In fact, global phone number generation must be used in conjunction with professional number screening tools (such as ITG Global Screening) to avoid the risk of account blocking and ensure the stable progress of cross-border marketing.

This article will analyze why global phone number generation is inseparable from number screening tools, and how ITG's global screening can help with risk control.Relying solely on globally generated phone numbers and using them directly for marketing without filtering will trigger account bans based on three dimensions: "number quality, platform rules, and user complaints."

Through multi-dimensional screening, "virtual numbers, high-complaint numbers, and linked banned numbers" are removed from the global phone number pool, retaining only "real, valid, and low-risk" numbers.
