In WhatsApp customer operations, many enterprises invest significant effort in expanding their customer base. While the customer pool may seem large in size, it is filled with invalid accounts such as empty numbers, virtual numbers, and non-target users—leading to low conversion efficiency and high operational costs. A professional WhatsApp verification tool is the key to building a high-quality customer pool: through such a tool, enterprises can screen for real and valid customers at the source, eliminate invalid adds, and lay a solid foundation for the customer pool. Relying on ITG Global Screening—a dedicated WhatsApp verification tool—enterprises can further achieve full-process empowerment covering "source screening → precise tiering → dynamic optimization," transforming the customer pool from "quantity-driven" to "quality-focused." Starting from the harms of invalid adds, this article will explain in detail how ITG Global Screening helps enterprises build high-quality customer pools and completely eliminate invalid adds.
Many enterprises overlook source number screening when expanding their WhatsApp customer base, allowing invalid adds to enter the customer pool. This leads to 3 core issues, turning the customer pool into a "repository of invalid resources":
- Flood of empty/disconnected numbers: Numbers purchased from third-party channels typically include over 30% empty or disconnected numbers. These numbers cannot receive messages but occupy slots in the customer pool.
- Pervasive virtual numbers: Virtual numbers (e.g., Google Voice, TextNow) account for over 15%. Most of these accounts are temporarily registered, with a user retention rate of less than 3%, making effective conversion impossible.
- Infiltration of non-target users: Without precise screening, users unrelated to the product (e.g., students mixed into a B2B service customer pool) are included, further reducing the proportion of valid customers to below 40%.
Real Case: A cross-border e-commerce enterprise had a customer pool of 100,000 numbers. After screening with a WhatsApp verification tool, only 38,000 (less than 40%) were valid customers; the rest were invalid adds. The operation team wasted long hours on these invalid customers.
- Wasted effort: Operation teams spend over 50% of their time maintaining invalid customers—such as sending messages to empty numbers and following up with non-target users—severely squeezing time for high-quality customers.
- Cost waste: Sending content to invalid customers results in futile losses of SMS fees, API call fees, and content production costs. The cost per customer operation rises from 20 yuan to 50 yuan.
- Distorted data: Invalid customers skew operational data (e.g., lowering reach and conversion rates), misleading strategy adjustments (e.g., incorrectly attributing poor results to "unattractive content" instead of high invalid customer ratios).
- Over-disturbance: Frequent irrelevant messages to non-target users trigger resentment and even lead to being marked as "spam," damaging the brand image.
- High-quality customers ignored: Due to scattered efforts on invalid customers, high-quality customers’ needs are not addressed promptly (e.g., delayed responses to inquiries, missed exclusive offers), resulting in customer churn.
As a professional WhatsApp verification tool, ITG Global Screening works across three dimensions—"source screening, precise tiering, and dynamic optimization"—to help enterprises build high-quality customer pools and eliminate invalid adds:
ITG Global Screening blocks invalid adds at the source through multi-dimensional detection, ensuring only real and valid customers enter the customer pool:
- Empty/disconnected number identification: Connects to real-time global operator data to verify number validity in 1 second. With 99.5% accuracy in identifying empty/disconnected numbers, it eliminates them entirely.
- Accurate virtual number filtering: Built-in virtual number database identifies over 20 mainstream virtual number segments with over 98% accuracy, preventing virtual numbers from entering the customer pool.
- Target user screening: Extracts users’ basic attributes (age, region), interest tags (e.g., "cross-border e-commerce," "maternity"), and behavioral characteristics (activity level, interaction records) to retain only target users matching the product.
Case Result: A maternity brand used ITG Global Screening for source screening, eliminating 22,000 invalid adds from 50,000 potential numbers. The 28,000 customers finally added to the pool were all "females aged 25-35 + maternity-focused + highly active," raising the valid customer ratio to 100%.
A high-quality customer pool requires clear tiering. ITG Global Screening enables precise customer tiering through tag extraction, laying the groundwork for differentiated operations:
- Core customers (10%-20%): Active in the past 7 days + multiple inquiries + high matching degree (e.g., "procurement managers aged 30-45 + mechanical parts needs"). Require one-on-one dedicated operations.
- Potential customers (30%-40%): Active in the past 30 days + single inquiry + medium matching degree. Require targeted nurturing.
- Basic customers (40%-50%): Active in the past 90 days + no inquiries + basic matching degree. Require light activation.
- Awareness stage: First contact + content browsing. Push industry insights and product introductions.
- Consideration stage: Comparative inquiries + information requests. Push customer cases and product advantages.
- Decision stage: Price negotiations + detail confirmation. Push exclusive discounts and after-sales guarantees.
Application Value: A B2B enterprise achieved a 5% to 18% increase in core customer conversion rates and a 30% rise in potential customer activation rates through tiered operations.
Customer pool quality changes over time. ITG Global Screening enables continuous optimization through dynamic detection, preventing "aging" of the customer pool:
- Regular invalid customer cleanup: Monthly automatic screening to eliminate "inactive for 90 days" or "account abnormal" customers, maintaining pool activity.
- Supplementation with high-quality new customers: Screen numbers from new acquisition channels to add "real, high-matching" customers, keeping the pool size stable.
- Real-time tag updates: Update customer tags based on interaction behavior (e.g., upgrading "potential customers" to "core customers") and adjust operation strategies accordingly.
Data Result: A SaaS enterprise maintained over 85% activity in its customer pool through dynamic optimization. The proportion of core customers rose from 15% to 25%, and monthly new signed customers increased by 40%.
Using ITG Global Screening (WhatsApp verification tool) to build a high-quality customer pool requires no professional skills—ordinary operators can get started in 10 minutes. The specific process is as follows:
First, based on product/service characteristics, clarify core standards for high-quality customers and determine screening dimensions for the WhatsApp verification tool:
- For cross-border e-commerce (3C products): Core standards: "region (Europe/US) + age (18-40) + interest (tech-focused) + activity (active in 30 days)."
- For B2B enterprises (chemical raw materials): Core standards: "region (industrial hubs) + identity (procurement manager) + industry (chemical/manufacturing) + risk level (low risk)."
- For service industries (online education): Core standards: "region (target country) + identity (parent/student) + demand (language learning) + interaction willingness (high engagement)."
Use ITG Global Screening to detect newly acquired numbers at the source, ensuring only high-quality customers enter the pool:
- Upload new number lists: Organize WhatsApp numbers to be added into Excel/CSV format and upload to the ITG backend.
- Set screening dimensions: Check the defined core standards (e.g., "region screening + interest tags + activity detection").
- Launch screening: The system automatically completes detection—100,000 numbers take only 1-2 hours. Results are categorized as "valid customers," "invalid customers," and "pending observation."
- Import to customer pool: Only import "valid customers" into the enterprise pool. Eliminate invalid customers directly, and create a separate list for "pending observation" customers (e.g., low activity but high matching degree) for later activation.
Tier valid customers and match each tier with exclusive operation plans:
- Core customers:
- Operations: One-on-one dedicated customer service, customized solutions, priority access to discounts.
- Goal: Increase repurchase and referral rates.
- Potential customers:
- Operations: Push product cases, industry insights, limited-time trials.
- Goal: Activate demand and upgrade to core customers.
- Basic customers:
- Operations: Push light content (e.g., short video reviews), holiday greetings.
- Goal: Maintain engagement and prevent churn.
Optimize the customer pool monthly with ITG Global Screening to ensure long-term quality:
- Clean up invalid customers: The system automatically screens and eliminates "inactive for 90 days" or "abnormal" customers.
- Supplement new customers: Screen numbers from new acquisition channels to add high-quality customers and stabilize pool size.
- Update tiers and strategies: Adjust customer tiers (e.g., upgrade potential customers to core customers) based on interaction data, and optimize operation strategies accordingly (e.g., add exclusive benefits for core customers).
A cross-border maternity enterprise used this process to increase the valid ratio of its customer pool from 40% to 95% in 3 months. Core customer conversion rates rose from 3% to 12%, significantly improving pool quality.
- "Watered-down" customer pool: Of 100,000 numbers, only 35,000 (35%) were valid; the rest were invalid adds.
- Low operational efficiency: The team spent 50% of its time on invalid customers. Core customers received delayed responses, with a churn rate of 20%.
- High costs: Monthly costs wasted on invalid customer outreach reached 12,000 yuan, with a cost per customer operation of 45 yuan.
- Source screening: After ITG screening, the valid ratio of newly acquired numbers reached 98%. 28,000 high-quality customers were added in 6 months.
- Precise tiering: Customers were divided into core (8,000), potential (15,000), and basic (18,000) tiers. Differentiated operations raised core customer conversion rates from 5% to 18%.
- Dynamic optimization: Monthly invalid customer cleanup maintained over 90% pool activity. The cost per customer operation dropped from 45 yuan to 18 yuan, saving 216,000 yuan in 6 months.
The core value of a customer pool lies in "effective conversion," not "size." Use WhatsApp verification tools for strict screening to ensure valid customers account for over 80%, avoiding blind pursuit of quantity at the cost of quality.
For global customer pools, use ITG’s "regional adaptation" feature to screen target market customers. Ensure compliance with local regulations (e.g., EU GDPR) to avoid customer loss or account restrictions due to non-compliance.
Free tools can only identify basic empty numbers—they cannot accurately filter virtual numbers or extract user tags, resulting in a valid customer ratio of less than 60%. ITG Global Screening achieves a valid ratio of up to 98%, saving operational costs in the long run.
The customer pool screened by the WhatsApp verification tool must be closely linked to operational actions (e.g., dedicated operations for core customers, targeted nurturing for potential customers). Avoid "screening in isolation from operations" to maximize the customer pool’s value.
Building a high-quality customer pool is not about "increasing quantity" but "ensuring quality at the source." ITG Global Screening—a dedicated WhatsApp verification tool—helps enterprises eliminate invalid adds and build a high-quality customer pool through source screening, precise tiering, and dynamic optimization.
Remember: The customer pool is one of an enterprise’s core assets, and its quality determines operational results and long-term revenue. Use ITG Global Screening (WhatsApp verification tool) to control customer quality at the source, turning the customer pool into a "growth engine" rather than a "burden." Launch ITG now—see significant improvements in customer pool quality within 6 months, and double conversion efficiency and operational ROI!
