In today's fierce digital marketing competition, countless companies face a common dilemma: carefully planned marketing campaigns and huge investments of resources ultimately fail like a pebble thrown into the sea.Many teams are still using the traditional and inefficient TG screening method, ignoring the key role of systematic tools.This article will provide an in-depth analysis of how to fundamentally improve the reach and conversion rates of telegram marketing through the ITG global screening platform, ensuring that every marketing investment generates its due value.

The first and foremost problem is the lack of accuracy in the target audience. Many companies blindly pursue the quantity of numbers and ignore the quality, resulting in a large amount of marketing resources being wasted on invalid numbers.Research shows that among the numbers that have not been screened by the system, an average of 35% of the numbers do not exist or have been shut down, and another 20% of the numbers are valid but not the target customers.

Even if the number is valid and belongs to the target group, if the user is no longer actively using TG, the marketing message will not reach them.

The traditional TG number screening method is completely unable to determine the active status of the user behind the number, which is another important reason why the message falls into oblivion.Intelligent tag generation: Automatically tags valid accounts with "activity tags", "demand tags", and "spending potential tags" without manual tagging.

The 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".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.
