Still Manually Checking Invalid Numbers? WhatsApp Screening with Intelligent Filtering Saves Time and Boosts Efficiency!

I. Hitting the Pain Points: How "Torturous" Is Manual Invalid Number Checking?

Pain Point 1: Time-Consuming and Labor-Intensive, Leading to "Inflated" Labor Costs

• Business Dilemma: Manually verifying one WhatsApp number takes 8-10 minutes, including steps such as sending verification messages, waiting for replies, and marking status. Screening 100,000 numbers requires 5 employees to work continuously for one month, with labor costs alone exceeding ¥30,000. Moreover, employees are prone to misjudgments and omissions due to fatigue.
• Value of WhatsApp Screening: ITG Global Screening processes 12,000 numbers per hour. Screening 100,000 numbers takes only 8.5 hours and can be operated by one employee, directly reducing labor costs by 90%. With an accuracy rate of 99.3%, it avoids missed screening of invalid numbers caused by human errors.
• Real Case: A cross-border home furnishing enterprise spent ¥25,000 monthly hiring 3 employees for manual number checking before using WhatsApp screening, yet 15% of invalid numbers were still missed. After adopting ITG Global Screening, only one employee needs to spend 2 hours per month to complete screening, labor costs dropped to ¥5,000, and the missed rate of invalid numbers was 0.
  
  

Pain Point 2: Progress Falling Behind, Causing Marketing Plans to "Be Delayed"

• Operational Challenge: The original plan was to "launch one round of marketing activities per week", but manual number checking took 10 days, forcing the activities to be adjusted to once every two weeks and missing market windows. When facing sudden marketing needs (such as holiday promotions), manual screening could not respond quickly, and temporary promotion opportunities had to be abandoned.
• Role of WhatsApp Screening: ITG Global Screening supports "batch rapid screening" — 20,000 numbers are completed in 17 minutes, and 40,000 numbers in 35 minutes. It can respond to urgent marketing needs at any time, ensuring promotion plans proceed on schedule, and 2-3 more rounds of marketing activities can be carried out monthly.
• Efficiency Comparison: A cross-border electronics business needed 15 days to complete one round of marketing activities (from "screening numbers - sending messages - following up with customers") without using WhatsApp screening. After using ITG Global Screening, the same process takes only 5 days. It can reach 30% more potential customers monthly, and the activity participation rate increased by 40%.
  
  

Pain Point 3: Inaccurate Data, Leading to "Deviated" Decision Directions

• Hidden Risk: Manual checking cannot accurately mark number types (such as virtual numbers and accounts linked to bans), and can only identify empty or suspended numbers. Misjudging virtual numbers as valid and sending messages not only wastes resources but also may trigger WhatsApp platform risk control, resulting in account bans. Incorrect data also misleads operational decisions — for example, mistakenly attributing "low response rates" to copywriting rather than invalid numbers.
• Advantage of WhatsApp Screening: ITG Global Screening can accurately mark 6 types of invalid numbers, including "empty numbers, suspended numbers, virtual numbers, inactive numbers in the past 90 days, and accounts linked to bans". It generates detailed data reports to help teams clearly identify the root cause of problems and avoid decision-making errors.
• Decision Case: A cross-border beauty brand had a message response rate of only 2% after manual checking before using WhatsApp screening, mistakenly attributing it to insufficient copywriting appeal. It revised the copy 4 times within a month with no improvement. After eliminating 5 types of invalid numbers using ITG Global Screening, the real response rate reached 9%, confirming that the copy did not need adjustment. Instead, it optimized the sending time, eventually increasing the response rate to 13%.
  
  
  

II. Core Advantages: How Does ITG Global Screening (WhatsApp Screening Tool) Achieve "Hassle-Free and Efficient"?

Advantage 1: Fully Automated Operation, No Manual Intervention Required

• Automatic Number Recognition: After uploading numbers, the system automatically identifies whether the format is correct. If the country code is missing, it completes it with one click, no manual modification needed.
• Automatic Classification and Marking: After screening, numbers are automatically classified into categories such as "valid numbers, empty numbers, virtual numbers, and risky numbers", eliminating the need for manual secondary organization.
• Automatic Report Generation: Real-time screening reports are generated, including data such as the number of valid numbers, the proportion of various invalid numbers, and the proportion of target customers. No manual statistics or analysis is required.
• User Feedback: When using the WhatsApp screening tool, Operator Zhang uploaded 15,000 numbers, and the system automatically completed format repair, screening marking, and report generation. He only clicked 3 buttons throughout the process. "I don’t have to stare at the screen and record manually; the time saved allows me to follow up with 20 more core customers."
  
  

Advantage 2: Comprehensive Functions, No Need to Switch Tools

• Intelligent Screening Function: Supports screening numbers from over 200 countries/regions. It can accurately screen by gender, age, activity level, and profile completeness, and automatically eliminate various invalid numbers.
• Number Generation Function: Customizes number generation based on "country code + area code". For example, to develop the Tokyo, Japan market, local numbers starting with "+81(3)" can be generated, and then valid customers are screened through WhatsApp screening to ensure geographical accuracy.
• Account Nurturing Detection Function: Enter a WhatsApp account to automatically detect its registration duration, risk control level, and number of reports. It generates a phased nurturing plan covering "registration period - initial period - stable period", increasing the survival rate of new accounts to over 92%.
• Tool Comparison: A foreign trade company previously used 3 different tools for number generation, screening, and account nurturing, spending 1.5 hours switching tools daily. After using ITG Global Screening, no tool switching is needed throughout the process, saving 1.2 hours daily and improving operational efficiency by 30%.
  
  

Advantage 3: Low Threshold for Getting Started, No Professional Skills Required

• Visual Interface: The backend is categorized into "Number Upload, Screening Settings, Result Export, and Account Nurturing Detection". There are no professional terms, and each function button is equipped with Chinese descriptions and operation GIFs. New users can operate independently within 10 minutes.
• Simple Settings: Screening conditions are simplified to "checkbox options". For example, to screen "active female customers aged 25-40 in the US", users only need to check "Region - US", "Gender - Female", "Age - 25-40", and "Activity - Past 30 Days". No manual rule writing is required.
• 24/7 Customer Service: When encountering operational problems, users can contact customer service at any time. Remote assistance and demonstrations are supported, and problems are solved within 1 minute, no need to wait for technical team support.
  
  
  

III. Practical Process: 4-Step Intelligent Screening with ITG Global Screening (WhatsApp Screening Tool)

Step 1: Prepare Numbers, Completed in 3 Minutes

• Upload Existing Numbers: Organize numbers into Excel/TXT format (one number per line, including the country code, e.g., "+12121234567"), and remove special characters such as spaces and hyphens.
• Generate New Numbers: Enter the "Number Generation" module, select the target country (e.g., "UK"), input the area code (e.g., "20" for London), and click "Generate". The system automatically generates 10,000-50,000 compliant numbers.
• Newbie Tip: If the number format is messy, use the "Automatic Format Repair" function. The system clears special characters and completes country codes with one click, no need to modify each number manually.
  
  

Step 2: Set Screening Criteria, Configured in 5 Minutes

• Basic Screening (Mandatory): Check "Eliminate empty/suspended numbers", "Eliminate virtual numbers", "Eliminate inactive numbers in the past 90 days", and "Eliminate accounts linked to bans".
• Precise Screening (Optional): Check "Region - Europe", "Gender - Male", "Age - 18-40", "Profile Completeness - With avatar + With signature", and "Activity - Past 30 Days".
• Start Screening: Click "Start Screening". The system displays the estimated time (e.g., approximately 17 minutes for 20,000 numbers). Users can wait in the backend or receive SMS notifications.
  
  

Step 3: View Report, Analyzed in 2 Minutes

• Number of Valid Numbers: Clarify the base of customers that can be targeted.
• Proportion of Invalid Number Types: Understand the proportion of various invalid numbers (such as empty numbers and virtual numbers) to optimize subsequent number procurement channels.
• Proportion of Target Customers: If the proportion is below 50%, adjust the screening criteria to ensure accurate targeting.
  
  

Step 4: Export Valid Numbers, Implemented in 10 Minutes

• Export Formats: Supports three formats — TXT, Excel, and VCF. They can be directly imported into WhatsApp mass messaging tools without secondary conversion.
• Export Options: Users can choose to "Export only valid numbers" or "Export by category". Prioritize exporting "highly active + highly precise" customers to advance the sending plan on the same day.
• Practical Case: A cross-border footwear business screened 30,000 European numbers using this process, completing the operation in 25 minutes and exporting 9,000 valid customers. After sending messages on the same day, it received 58 inquiries and closed 15 deals, far exceeding the conversion effect of manual checking.
  
  
  

IV. Pitfall Avoidance Guide: 5 Common Mistakes in Using WhatsApp Screening Tools

1. Over-Reliance on Manual Rechecking: Believing that manual verification is still needed after WhatsApp screening, and spending an extra 2 hours on spot checks, which instead reduces efficiency. ITG Global Screening has an accuracy rate of 99.3%, so no manual rechecking is required, and messages can be sent directly.
2. Setting Too Narrow Screening Criteria: Checking too many screening conditions (e.g., selecting "Europe + North America + 25-30 years old + With avatar + With signature + Active in the past 7 days" at the same time) results in too few valid numbers, requiring re-adjustment of criteria and wasting time. It is recommended to set 2-3 criteria based on core needs first, then refine them gradually.
3. Ignoring Number Format Standardization: Uploading numbers without removing spaces or hyphens, or without completing country codes, leading to unrecognizable numbers by the system and requiring re-organization and upload. It is recommended to use the "Automatic Format Repair" function in advance to avoid repeated operations.
4. Sending Messages Directly Without Viewing Reports: Skipping the report analysis step and directly exporting valid numbers for messaging. If the proportion of target customers is low, sending resources will still be wasted. Confirm that the proportion of target customers is ≥60% before proceeding with subsequent operations.
5. Not Updating Screening Rules for a Long Time: The risk control rules of the WhatsApp platform are updated monthly, and WhatsApp screening tools need to synchronize identification standards. ITG Global Screening automatically updates rules, no manual adjustment required, ensuring screening results are always accurate.
