WhatsApp Number Screening: A Core Tool for Overseas Enterprises to Precisely Reach Overseas Users, Locking in High-Conversion Targets in Three Steps

In the layout of global business, WhatsApp has become a crucial channel for overseas enterprises to reach overseas markets, thanks to its over 2 billion monthly active users. However, invalid accounts and non-target users in massive number databases greatly reduce marketing effectiveness. As a targeted solution, WhatsApp Number Screening can accurately identify active WhatsApp accounts that have been activated, eliminating empty numbers, suspended numbers, and non-target users. This ensures that every information delivery by enterprises precisely reaches potential customers. More importantly, WhatsApp Number Screening is not a standalone tool. When used in conjunction with ITG Global Screening, it can integrate multi-dimensional user data to further narrow down the target scope. By following the three-step process of "screening - verification - reach," enterprises can easily lock in high-conversion users and completely bid farewell to the dilemma of "casting a wide net but yielding low returns" in cross-border marketing.

I. Cross-Border Marketing Pain Points for Overseas Enterprises: Why Is WhatsApp Reach Effectiveness Poor?

Overseas user numbers acquired by overseas enterprises often include accounts that are not activated on WhatsApp, long-term inactive, or cancelled. Marketing data from a cross-border e-commerce enterprise targeting the European and American markets shows that invalid numbers account for 40% of its number database. Monthly SMS costs for sending new product information and discount notifications to these numbers exceed 50,000 yuan, with zero conversion, resulting in significant resource waste.

Even if enterprises reach users with activated WhatsApp accounts, marketing will still fail if their needs cannot be accurately matched. For example, sending high-end luxury information to users interested in "affordable home furnishings" in the Middle East not only results in zero conversion rate but may also lead to users blocking the account, affecting subsequent brand communication.

Regulations on user data usage vary significantly across countries: the EU's GDPR requires obtaining explicit user consent before sending marketing information, while Brazil's General Data Protection Law restricts cross-border data transmission. If enterprises only rely on traditional methods for number screening, they are likely to violate legal red lines and face heavy fines. An overseas social platform was once fined 4% of its annual turnover in the EU market for failing to conduct compliant number screening.

II. WhatsApp Number Screening + ITG Global Screening: Locking in High-Conversion Targets in Three Steps

Step 1: Initial Screening of "Valid Accounts" to Eliminate Invalid Numbers

By connecting to official WhatsApp interfaces, WhatsApp Number Screening verifies the activation status of accounts corresponding to numbers in real time, automatically marking and eliminating invalid numbers that are unactivated or cancelled, and initially screening out reachable active accounts. On this basis, ITG Global Screening further supplements account activity data verification. By analyzing indicators such as "login frequency in the past 30 days" and "message response rate," it screens out highly active accounts with "≥ 3 active times per week" and excludes long-term dormant accounts.

For example, a cross-border educational institution targeting the Southeast Asian market first used WhatsApp Number Screening to filter 65,000 activated accounts from 100,000 numbers. Then, with ITG Global Screening, it eliminated 12,000 long-term inactive accounts, finally obtaining 53,000 highly active valid accounts. This effectively reduced subsequent marketing resource waste, directly cutting SMS sending costs by 47%.

Step 2: Refined Screening of "Target Users" to Match Precise Needs

After completing the screening of valid accounts, WhatsApp Number Screening can narrow down the scope based on basic dimensions such as user region and language preferences. ITG Global Screening, on the other hand, integrates internal enterprise CRM data and third-party compliant data sources (such as user consumption records and browsing tracks) to add "behavioral tags" for further precise positioning.

Taking a cross-border clothing enterprise as an example, its target users are "females aged 30-45 in Europe, with clothing purchase records in the past 3 months, and a preference for casual styles." Through WhatsApp Number Screening, it first locates activated accounts in "European regions, using English/French." Then, with ITG Global Screening, it adds conditions such as "having clothing purchase records and browsing casual-style products," finally screening out 28,000 precise target user numbers. The conversion rate of subsequent casual clothing new product information pushes increased by 3.2 times compared to before.

Step 3: Compliance Verification to Avoid Risks

ITG Global Screening has built-in compliance templates for more than 20 countries and regions worldwide, which can automatically verify whether the WhatsApp Number Screening process complies with local regulations: for the EU market, it automatically checks whether users have signed the WhatsApp marketing consent form; for the Southeast Asian market, it confirms whether data meets localized storage requirements. At the same time, ITG Global Screening also marks numbers from illegal data sources and prohibits them from being included in the screening scope, avoiding compliance risks from the source. A cross-border e-commerce enterprise successfully passed the inspection of local regulatory authorities in Brazil without any compliance complaints through this step.

III. Core Advantages of WhatsApp Number Screening: Helping Enterprises Improve Marketing Effectiveness

After combining WhatsApp Number Screening with ITG Global Screening, the cross-border marketing reach rate of enterprises can increase from an average of 25% to over 85%. A cross-border logistics enterprise achieved a 92% reach rate for package notifications through this combined screening, with user complaints about missed notifications decreasing by 60%. At the same time, marketing costs were reduced by more than 50%, and the cost per customer acquisition dropped from 120 yuan to 58 yuan.

Multi-dimensional screening highly matches marketing information with user needs, significantly improving the conversion rate. A cross-border beauty brand targeting the European and American markets used WhatsApp Number Screening + ITG Global Screening to lock in users who are "females aged 25-35, having browsed beauty products in the past month, and preferring natural ingredients." By pushing discounts for new natural beauty products, the conversion rate reached 8.5%, far exceeding the industry average of 3%.

The compliance verification function of ITG Global Screening ensures that WhatsApp Number Screening fully complies with local regulations throughout the process, helping enterprises avoid legal risks and ensure the safe operation of cross-border business. An overseas SaaS enterprise carried out marketing in more than 10 global markets with the assistance of this combination, without any compliance disputes, and its brand reputation was significantly improved.

IV. Practical Cases: Practical Application Effects of WhatsApp Number Screening

Case 1: Cross-Border E-Commerce Enterprise (Target Market: Europe and America)

Case 2: Cross-Border Tourism Enterprise (Target Market: Southeast Asia)

V. Practical Suggestions for Enterprises Using WhatsApp Number Screening

User needs in different markets change with seasons and festivals. Enterprises need to adjust the dimensions of WhatsApp Number Screening monthly based on the market data report of ITG Global Screening. For example, during the Ramadan period in Southeast Asia, the screening condition of "focusing on 'festival gifts'" can be added to improve marketing relevance.

After screening, target users can not only receive marketing information but also be guided to join WhatsApp groups. User stickiness can be improved through daily interactions (such as product Q&A and exclusive flash sales). ITG Global Screening can synchronize the activity data of group users, helping enterprises adjust the frequency and content of interactions and avoid over-marketing.

Initially, 1-2 core markets can be selected to test the effect of WhatsApp Number Screening. Adjust the screening dimensions based on data such as conversion rate and reach rate. After the effect stabilizes, gradually expand to other markets to reduce trial-and-error costs.

VI. Conclusion

For overseas enterprises, precisely reaching overseas users is the key to successful cross-border marketing, and WhatsApp Number Screening is exactly the core tool to achieve this goal. By initially screening valid accounts and refining target users, combined with the compliance guarantee and data supplementation of ITG Global Screening, it helps enterprises lock in high-conversion targets in three steps, significantly improving marketing effectiveness and reducing costs. In the context of increasingly fierce cross-border business competition, mastering the usage of WhatsApp Number Screening and collaborating with professional tools will become an important competitive advantage for enterprises to expand overseas markets, helping them achieve efficient growth in the global market.
