​​Email, WhatsApp, LinkedIn, and Facebook accounts.

​​In the digital marketing wave of 2025, WhatsApp filtering became an essential lesson I couldn't avoid. With over 2 billion WhatsApp users worldwide, accurate WhatsApp filtering directly determined the effectiveness of my promotions.​​Initially, I thought it was just a simple task of filtering phone numbers, but I ended up taking a lot of detours.

​​From blind optimism based on "format" to the inefficient and torturous process of manually dialing, and then to discovering the power of ITG's global filtering tool, I finally figured out an efficient method for filtering WhatsApp numbers.​​This article will share my experience and guide you through the latest WhatsApp number filtering strategy for 2025, with the core tool being ITG full-domain filtering.​​When I first started screening WhatsApp numbers, I naively thought that as long as the number format "looked right," it was a good number.

​​This made me realize that the first step in WhatsApp's number screening process is not format calibration, but rather having a scientific verification system.​​Manual verification is suitable for small-scale testing, but when faced with a database of 100,000+ phone numbers, it's simply asking for trouble.

​​This tool has completely changed the way I work, not only boosting my efficiency but also making the screening results incredibly accurate.

​​With over 3 billion WhatsApp users, accurate WhatsApp number filtering is not only key to improving conversion rates, but also an essential means to avoid wasting resources and compliance risks.​​The system provides automatic inactive account removal, combining active, online time, and interaction frequency filtering to ensure your campaigns reach your target audience and improve conversion efficiency.

​​The cloud control platform supports both self-screening and proxy screening, eliminating manual effort and easily managing batch account screening and management across multiple platforms, saving your team significant time.​​Using avatar and nickname filtering, you can quickly identify potential customer groups, achieving precise and high-ROI social media promotions.

​​The system supports batch generation and filtering of mobile phone numbers in regions like India, Japan, and Mexico, enabling cross-border marketing campaigns to reach target users more quickly and efficiently. The cloud-based control system combines interaction and online filtering to monitor target account activity patterns in real time, ensuring every ad campaign reaches high-potential customers.​​Whether it's Telegram, LinkedIn, or Facebook, the system offers unified management and batch filtering based on age, gender, and activity level, enabling precise multi-platform campaigns.
