In cross-border marketing, empty numbers (unregistered on WhatsApp) and inactive accounts (long-term inactive, fake registered) are like "invisible traps". They not only make enterprises' promotional information fall on deaf ears but also consume a lot of labor, time, and SMS costs. Traditional manual verification of 10,000 numbers requires 3 people to spend 2 days, with an error rate of over 15%. The emergence of WhatsApp Batch Detection has completely changed this situation: through automated technology, it realizes "one-click upload, automatic verification, and precise classification" of 10,000-level numbers, and can complete the work that takes humans several days within a few hours. More importantly, WhatsApp Batch Detection is not a single "status query tool". When used in conjunction with ITG Global Screening, it can also deeply identify empty numbers and inactive accounts from three dimensions: "account status", "active behavior", and "authenticity", allowing enterprises to bid farewell to inefficient verification, quickly obtain a clean list of valid users, and lay a foundation for precise reach in cross-border marketing.
I. Recognize the Hazards of Empty Numbers and Inactive Accounts: Why Must They Be Efficiently Removed?
Before launching WhatsApp Batch Detection, it is necessary to first clarify the specific hazards of empty numbers and inactive accounts to cross-border business, so as to formulate more accurate verification goals:
- Direct Waste of Marketing Resources: Sending information to empty numbers means every SMS cost (0.1-0.3 yuan) is an invalid investment; pushing promotional content to inactive accounts, even if successfully delivered, results in a conversion rate of less than 0.5%. A cross-border e-commerce enterprise once sent new product information to 50,000 unverified numbers. Subsequent statistics showed that empty numbers and inactive accounts accounted for 42%, directly wasting 12,000 yuan in costs;
- Reduce the Efficiency of Operational Decision-Making: If empty numbers and inactive accounts are not removed, enterprises will mistakenly include "invalid data" in the user base, leading to the misjudgment of "user growth but stagnant conversion", which in turn affects the adjustment of marketing strategies. For example, a cross-border social app did not use WhatsApp Batch Detection for verification, mistakenly treating 20,000 inactive accounts as "potential users" and continuing to invest in promotional resources, ultimately leading to a 30% drop in ROI;
- Increase the Risk of Platform Violations: Sending a large amount of information to inactive accounts (especially fake registered accounts) may cause WhatsApp to identify the enterprise as a "spammer", resulting in restrictions or even bans on the enterprise's marketing accounts, affecting long-term operations.
II. Practical Process of WhatsApp Batch Detection: Four Steps to One-Click Remove Empty Numbers/Inactive Accounts
Step 1: Data Preparation - Standardize Numbers to Be Verified
The premise of efficient verification is to ensure that the number format is compliant. WhatsApp Batch Detection supports the import of multiple data formats, but basic processing must be completed first:
- Format Unification: Uniformly supplement country/region codes to numbers (e.g., add "+86" to Chinese numbers, "+62" to Indonesian numbers), and delete special characters such as spaces and hyphens (e.g., process "+1 234-567-8901" into "+12345678901") to avoid verification failure due to format errors;
- Data Deduplication: Use the "duplicate data filtering" function built into WhatsApp Batch Detection to automatically delete duplicate entries in the number database. An enterprise imported 100,000 Southeast Asian numbers, and after deduplication, 8,000 duplicate data entries were reduced, avoiding resource waste caused by repeated verification;
- Format Verification: The system automatically filters out invalid numbers with "abnormal digits (e.g., less than 8 digits or more than 15 digits)" and "containing letters/symbols", initially improving the purity of the data to be verified. This link can eliminate about 5%-10% of obviously invalid data.
After preparation, save the processed numbers in Excel or CSV format and upload them to the WhatsApp Batch Detection system.
Step 2: Core Verification - One-Click Launch of Empty Number/Inactive Account Identification
This is the core link of WhatsApp Batch Detection, which requires no complicated operations and can be completed in just three steps:
- Upload Data: Log in to the WhatsApp Batch Detection system, enter the "Number Verification" module, click "Upload File", select the processed number file. The system supports one-time upload of up to 1 million pieces of data;
- Select Verification Dimensions: Check the verification options according to needs. Basic dimensions include "empty number detection (identifying unregistered/cancelled accounts)" and "inactive account detection (identifying long-term inactive accounts)". For in-depth verification, you can check "Connect to ITG Global Screening" to supplement the dimensions of "active behavior" and "account authenticity";
- One-Click Launch Verification: After confirming the parameters, click "Start Verification". The system automatically connects to the official WhatsApp API interface and processes the number data in parallel. It takes only 2-3 hours to verify 100,000 numbers and about 10-12 hours to verify 1 million numbers. No manual intervention is required during the period, and enterprises can check the verification progress in real time through the system.
A cross-border education institution completed the verification of 200,000 European numbers in just 3 hours through this link, automatically marking 52,000 empty numbers and 38,000 inactive accounts, with efficiency 40 times higher than manual verification.
Step 3: Result Output - Precisely Classify Valid/Invalid Accounts
After verification is completed, WhatsApp Batch Detection generates a detailed Verification Result Report, classifying numbers into four categories for enterprises to quickly screen:
- Valid Active Accounts: Registered on WhatsApp, with ≥5 logins and message interaction records in the past 30 days (if connected to ITG Global Screening, it will also mark "whether there are relevant consumption/browsing behaviors"). These accounts are the core marketing targets of enterprises;
- Valid Low-Active Accounts: Registered on WhatsApp, but with only 1-4 logins and little interaction in the past 30 days. They can be activated through "wake-up strategies" (e.g., exclusive discounts);
- Empty Numbers: Unregistered on WhatsApp or cancelled, which need to be directly removed to avoid subsequent delivery;
- Inactive Accounts: Registered but with no logins or interactions in the past 90 days, or identified as fake accounts with "virtual device registration" or "abnormal IP login" by ITG Global Screening, which need to be focused on removal.
The report also counts data such as the proportion of various accounts and verification accuracy. For example, the verification report of a cross-border e-commerce enterprise shows: valid active accounts account for 45%, valid low-active accounts account for 20%, empty numbers account for 25%, and inactive accounts account for 10%. Enterprises can accurately allocate marketing resources based on this.
Step 4: Secondary Optimization - Improve Accuracy by Combining with ITG Global Screening
If enterprises need to further improve the quality of valid accounts, they can connect WhatsApp Batch Detection to ITG Global Screening to complete secondary optimization:
- Supplement Active Behavior Data: ITG Global Screening can obtain data such as "group participation records in the past 30 days", "channel follow dynamics", and "message sending frequency" of accounts, helping WhatsApp Batch Detection more accurately determine the activity level. For example, although an account has "5 logins in the past 30 days", ITG data shows "no group interaction at all", so the system will reclassify it as a "low-active account";
- Verify Account Authenticity: ITG Global Screening identifies inactive accounts with virtual device registration and cross-regional abnormal login through "device model verification", "IP attribution matching", and "identity information association" (user authorization required). For example, a "+62 (Indonesia) number corresponding to a U.S. IP + virtual Android device" will be marked as a fake inactive account;
- Compliance Verification: ITG Global Screening has built-in compliance templates for more than 20 regions worldwide, ensuring that the verification process of WhatsApp Batch Detection complies with local regulations (e.g., "user-authorized verification" required by the EU GDPR) and avoiding compliance risks.
A cross-border SaaS enterprise used "WhatsApp Batch Detection + ITG Global Screening" to screen 32,000 "valid active + real accounts" from 80,000 numbers. The subsequent software trial conversion rate reached 28%, an increase of 15 percentage points compared with no secondary optimization.
III. Core Advantages of WhatsApp Batch Detection: Why Can It Replace Traditional Verification?
- Efficiency Surpasses Manual Work: Manual verification of 10,000 numbers requires 3 people/2 days, while WhatsApp Batch Detection only takes 1 hour, with efficiency increased by 144 times; processing 1 million numbers requires 30 people/20 days manually, while WhatsApp Batch Detection only takes 12 hours, significantly shortening the verification cycle;
- Cost Greatly Reduced: The labor cost of manually verifying 100,000 numbers is about 20,000 yuan. WhatsApp Batch Detection charges 0.1-0.3 yuan per entry, with a cost of only 10,000-30,000 yuan. Moreover, there is no need to bear additional costs such as employee training and equipment procurement, which is easily affordable for small and medium-sized enterprises;
- Higher Accuracy: Manual verification relies on subjective judgment, with an error rate of 15%-20%. WhatsApp Batch Detection achieves real-time data synchronization through API + secondary verification by ITG Global Screening, with an accuracy rate of over 98%. A comparison test by a cross-border logistics enterprise showed that the error rate of manual verification was 18%, while that of WhatsApp Batch Detection was only 1.5%.
IV. Practical Cases: Effect Improvement of Enterprises After Using WhatsApp Batch Detection
Case 1: Cross-Border E-Commerce Enterprise (Target Market: Malaysia, Southeast Asia)
- Pain Points: Previously, a 5-person team was used for manual number verification, verifying 150,000 numbers per month, taking 10 days, with a labor cost of 40,000 yuan. Empty numbers and inactive accounts accounted for 40%, resulting in a marketing reach rate of only 35% and a waste of 18,000 yuan in SMS costs;
- Solution: Adopt WhatsApp Batch Detection, check "empty number detection + inactive account detection + connect to ITG Global Screening", and verify according to the conditions of "Malaysia region + registered + ≥3 logins in the past 30 days + real account";
- Results: ① Efficiency: 150,000 numbers were verified in 3 hours, shortening the cycle by 98%; ② Cost: Verification cost was 15,000 yuan, saving 62.5%, and SMS cost was reduced by 12,000 yuan; ③ Accuracy: The proportion of valid active accounts increased to 55%, marketing reach rate reached 88%, and order conversion rate rose from 6% to 13%.
Case 2: Cross-Border Tourism Enterprise (Target Market: France, Europe)
- Pain Points: Manual verification of 50,000 numbers took 5 days, missing the "Christmas tourism" promotion period. Moreover, 12,000 inactive accounts were not identified, and after sending information to them, a "spam risk" warning was received from WhatsApp;
- Solution: Use WhatsApp Batch Detection to focus on verifying "whether registered + activity in the past 60 days", and supplement "whether searched for 'French Christmas tourism'" behavioral data through ITG Global Screening;
- Results: ① Efficiency: 50,000 numbers were verified in 1 hour, catching up with the promotion period; ② Risk Avoidance: Successfully removed 15,000 empty numbers and 12,000 inactive accounts, with no more platform warnings; ③ Conversion Improvement: Sent promotional information to 23,000 valid accounts, with a year-on-year growth of 60% in tourism product bookings.
