Improving International SMS Deliverability: Practical Methods for Global Real-Time Unavailable Number Detection

In Telegram (TG) lead generation scenarios, many companies are still manually adding friends one by one and verifying the validity of each customer. Not only can they only filter out a few dozen valid leads per day, but they also often waste a lot of time adding inactive accounts or non-target users.

In 2025, with the acceleration of digital transformation, efficient customer acquisition capabilities have become a core competitive advantage for enterprises.In an era of data explosion, accuracy is the primary criterion for evaluating Telegram number filtering platforms.

The marketing environment in 2025 requires platforms to have the ability to quickly process millions of data points, have stable concurrent processing capabilities, control response time within seconds, and facilitate batch operations.As data regulations become more comprehensive, platforms need to ensure end-to-end encryption of data transmission, compliant data processing procedures, robust privacy protection mechanisms, and complete security certifications.ITG's competitive advantage lies in its machine learning models, which are trained on over 1 billion data points, continuously learn and evolve autonomously, have industry-leading prediction accuracy, and adapt to various scenarios.

The real-time processing engine features millisecond-level response speed, 99.9% system stability, elastic scaling capability, and intelligent load balancing.To ensure effective implementation, attention should be paid to high-level support and participation, adequate team training, business process adaptability, and basic data quality.

After comprehensive evaluation, ITG's global filtering platform performed outstandingly in the Telegram filtering platform market in 2025. Its accurate filtering capabilities, stable system performance, and excellent user experience make it an ideal choice for improving customer acquisition efficiency.

However, companies should ultimately make their choices based on their specific needs, budget constraints, and stage of development.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.
