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 key to overcoming this predicament lies in a deep understanding and effective use of Telegram screening functions.
