In WhatsApp marketing, many enterprises are trapped in a vicious cycle of "costs wasted on invalid numbers"—sending messages to empty numbers, virtual numbers, and silent accounts, resulting in the futile loss of SMS fees, API fees, and labor costs, while marketing efficiency remains stagnant. A professional WhatsApp verification tool is exactly the key to breaking this dilemma: through such a tool, enterprises can accurately eliminate invalid numbers and ensure every marketing investment counts. Relying on ITG Global Screening—a dedicated WhatsApp verification tool—enterprises can further achieve full-process efficiency improvement covering "precise screening → efficient reach → cost optimization," drastically boosting marketing efficiency. Starting from the pain points of cost waste, this article will explain in detail how ITG Global Screening helps enterprises save costs, improve efficiency, and completely eliminate the trouble of invalid numbers.
Many enterprises fail to use WhatsApp verification tools and turn a blind eye to invalid numbers in their customer lists, leading to 3 types of cost waste that hinder marketing efficiency:
- SMS and API fees: Sending a message to one invalid number costs 0.1–0.3 yuan in SMS or API call fees. If 50% of your customer list consists of invalid numbers, 100,000 messages will waste 5,000–15,000 yuan.
- Content production costs: Copywriting, images, and videos created for promotions cannot reach users via invalid numbers, meaning 30%–50% of content costs are wasted.
- Data Reference: Enterprises not using WhatsApp verification tools waste an average of over 30,000 yuan in direct costs quarterly due to invalid numbers; large enterprises may even see losses exceeding 100,000 yuan.
- Screening costs: Operation teams spend 30% of their time manually checking invalid numbers. In a 10-person team, 3 people must be fully dedicated to "organizing numbers and eliminating invalid ones," accounting for over 30% of labor costs.
- Follow-up costs: After sending messages to invalid numbers, teams still spend time counting "unresponsive customers" and attempting follow-ups, only to discover these are invalid numbers—wasting labor costs twice over.
- Real Case: A cross-border e-commerce enterprise without a WhatsApp verification tool had a 3-person team spend 20 hours a week following up on "unresponsive customers," only to find 80% were invalid. This wasted over 6,000 yuan in labor costs.
- Misallocated resources: Limited marketing resources (e.g., discount quotas, dedicated customer service) are allocated to invalid numbers, leaving high-quality customers without key outreach and missing conversion opportunities.
- Delayed timelines: Time spent dealing with invalid numbers causes enterprises to miss industry milestones (e.g., Black Friday, Christmas promotions). By the time valid customers are screened, competitors have already seized market share.
- Data Comparison: Enterprises using WhatsApp verification tools launch new product promotions 3–5 days faster than those that don’t, and their conversion rate for high-quality customers is 2–3 times higher.
As a professional WhatsApp verification tool, ITG Global Screening does more than simply "eliminate invalid numbers." Through 3 core capabilities—"precise identification, efficient processing, and cost optimization"—it helps enterprises save 30%–60% of marketing costs while drastically improving efficiency:
ITG Global Screening accurately identifies various types of invalid numbers through 3 dimensions to avoid cost waste:
- Empty/disconnected number identification: Connects to real-time global operator data to verify number usability in 1 second, with 99.5% accuracy in identifying empty/disconnected numbers—eliminating them entirely.
- Virtual number filtering: Precisely identifies virtual numbers (e.g., Google Voice, TextNow) registered in batches. User retention for these numbers is less than 3%, and filtering them reduces invalid messages by 20%.
- Silent account detection: Identifies accounts inactive (no logins or interactions) for 90+ days. Conversion rates for these accounts are less than 1%, and eliminating them avoids follow-up cost waste.
A fast-moving consumer goods enterprise used ITG Global Screening (WhatsApp verification tool) to eliminate 80,000 invalid numbers from its 200,000-strong customer list. Subsequent message sends saved 8,000 yuan in direct costs per campaign and 30% in labor costs.
ITG Global Screening breaks through manual efficiency bottlenecks, improving screening efficiency by 100x and saving labor costs:
- Bulk import and processing: Supports bulk import in Excel/CSV formats, processing up to 500,000 numbers per batch. 100,000 numbers take only 1 hour to screen—100x faster than manual work.
- Automated operation: After setting screening dimensions, the system automatically completes "identification → marking → classification" without manual monitoring. Results are sent via email upon completion.
- Automatic format repair: Automatically supplements missing country codes (e.g., converting "1234567890" to "+11234567890") and removes special characters—no manual editing required.
A foreign trade enterprise previously needed 5 people working 3 days to manually screen 100,000 numbers. After switching to ITG, 1 person completed the task in 1 hour—labor costs reduced by 98% and efficiency boosted by 150x.
Through "precise screening + efficient reach," ITG Global Screening helps enterprises optimize both costs and efficiency:
- Cost optimization: After eliminating invalid numbers, direct costs are reduced by 30%–60%, labor costs by 30%, and cost per customer acquisition drops from 50 yuan to under 20 yuan.
- Efficiency improvement: Effective reach rate rises from below 30% to over 90%; open rates and response rates for marketing messages increase by 2–3x, and conversion rates by 1.5–2x.
- Data review: Automatically generates a "cost optimization report" including "invalid number ratio, cost savings amount, and efficiency improvement percentage," visualizing cost optimization results.
A cross-border 3C enterprise saved 240,000 yuan in marketing costs over 6 months using ITG Global Screening. Its conversion rate for valid customers rose from 1.2% to 4.8%, boosting marketing efficiency by 3x.
Using ITG Global Screening (WhatsApp verification tool) requires no professional skills—ordinary operators can get started in 10 minutes. The specific process is as follows:
- Format preparation: Save WhatsApp numbers to be screened in Excel/CSV format (no uniform format required—the system recognizes automatically).
- Log in to the tool: Register and log in to the ITG Global Screening backend, enter the "WhatsApp Verification Tool" module. New users receive a free quota for 10,000 numbers.
- Upload files: Click "Upload File," select the customer list. The system automatically starts format recognition and repair, completing upload within 10 seconds.
Based on cost optimization goals, select screening dimensions to ensure all invalid numbers are eliminated:
- Mandatory dimensions (checked by default): Empty/disconnected number identification, virtual number filtering, silent account detection (inactive for 90+ days).
- Optional dimensions:
- Region screening: Retain only numbers from target markets (e.g., "USA," "India") to avoid cross-regional invalid messages.
- Activity screening: Retain customers "active in the past 7 days" or "active in the past 30 days" to improve subsequent reach efficiency.
- Confirm settings: Click "Next." The system automatically displays "estimated screening time" and "estimated cost savings" (e.g., "10,000 numbers, estimated savings: 500 yuan").
- Start the task: Click "Launch Screening." The system runs automatically in the background—you can close the page or switch devices without affecting progress.
- Real-time monitoring: Check screening progress in the "Task Center," which supports pausing/resuming tasks. The system displays "numbers screened, invalid numbers count, and remaining time" in real time.
- Completion notification: Upon completion, the system sends dual notifications via email and SMS, including a link to the screening report.
- View the report: Click the link in the notification to access the "cost optimization report." Focus on:
- Invalid number ratio: Assess customer list quality (ratios below 10% indicate high-quality lists).
- Cost savings amount: Confirm direct and labor costs saved in this screening.
- Valid customer tags: Review valid customers’ region, activity level, and interest tags to prepare for subsequent outreach.
- Export and apply: Click "Export Valid Customers" and synchronize results to WhatsApp bulk messaging tools for precise outreach—marketing efficiency improves by 2–3x compared to before.
A maternity brand used this process to screen 150,000 numbers with ITG Global Screening, eliminating 60,000 invalid ones. Subsequent message sends saved 9,000 yuan, and valid customer response rates rose from 15% to 45%, doubling conversion rates.
- High costs: Sent messages to 200,000 numbers monthly, 60,000 of which were invalid. Direct costs wasted 6,000–18,000 yuan monthly, plus 20,000 yuan in wasted labor costs.
- Low efficiency: Effective reach rate was only 25%, response rate 10%, and conversion rate 1.2%. Marketing ROI was just 1:1.5—far below the industry average of 1:3.
- Delayed timelines: New product promotions required 10 days of advance number screening, missing optimal promotion windows and losing market share to competitors.
- Significant cost savings: Eliminated 360,000 invalid numbers over 6 months, saving 180,000 yuan in direct costs and 60,000 yuan in labor costs—total savings of 240,000 yuan.
- Notable efficiency improvement: Effective reach rate rose from 25% to 92%, response rate from 10% to 35%, and conversion rate from 1.2% to 4.8%—efficiency boosted by 3x.
- ROI optimization: Marketing ROI improved from 1:1.5 to 1:4.2, exceeding industry averages. New product promotions launched 5 days earlier, increasing market share by 20%.
Number status changes over time (e.g., user account cancellation, disconnected phones). It is recommended to re-screen with the WhatsApp verification tool monthly to maintain customer list quality and prevent invalid numbers from "reappearing."
Eliminating empty numbers alone is insufficient. Combine "region screening" (retaining target markets) and "activity screening" (retaining highly active customers) to further improve reach efficiency. One enterprise saved an additional 20% in marketing costs through this step.
Free tools can only identify basic empty numbers with accuracy below 70% and cannot filter virtual numbers or silent accounts. ITG Global Screening achieves 99.2% accuracy and eliminates invalid numbers across all dimensions, saving more costs in the long run.
Valid customers identified by the WhatsApp verification tool require precise operations based on tags (e.g., sending discounts to highly active customers, re-engagement content to low-active ones). This maximizes cost optimization effects and prevents valid customer churn.
In an era of rising marketing costs, waste from invalid numbers has become an unbearable burden for enterprises. A WhatsApp verification tool solves this problem at its source. As a professional WhatsApp verification tool, ITG Global Screening not only accurately eliminates invalid numbers and saves costs but also improves marketing efficiency, ensuring returns on every investment.
Remember: The core of marketing is not "how much you invest," but "where you invest." Use ITG Global Screening—a dedicated WhatsApp verification tool—to end cost waste from invalid numbers, boost marketing efficiency, and achieve the dual goals of "lower costs and better results." Launch ITG now—finish 3 days of screening work in 1 hour, and see significant cost optimization and efficiency improvement within 6 months!
