Amid the global wave of digital marketing, WhatsApp (WS) — with over 2 billion monthly active users and a 98% message open rate — has become a "golden channel" for cross-border enterprises to reach overseas customers. However, many enterprises struggle with WS marketing: they spend significant costs collecting numbers, yet achieve little results after deployment, and even trigger platform risk control due to invalid operations. In fact, the core of the problem lies in the lack of a professional WS screening tool. A high-quality WS screening tool helps enterprises filter out real, active target customers from massive numbers, ensuring precise allocation of marketing resources. As an industry-leading WS screening tool, ITG Global Screening, with its capabilities of multi-dimensional identification, global scenario adaptation, and automated implementation, has become the key for enterprises to break through marketing bottlenecks. When your WS marketing shows the following 5 key signals, it means you must rely on a WS screening tool to turn the tide — we will analyze each signal in detail below.
In global marketing, WS numbers collected by enterprises from exhibitions, cross-border platforms, and third-party data providers often contain a large amount of invalid resources — the primary cause of high marketing costs and poor performance. Specific manifestations include:
-
High proportion of invalid numbers: According to industry research, empty numbers, disconnected numbers, and canceled accounts account for over 30% of WS numbers collected by cross-border enterprises. In some emerging markets (e.g., Southeast Asia, India), due to the prevalence of temporary mobile numbers, the invalidity rate even reaches 60%. Additionally, there are mixed virtual numbers such as U.S.-based Google Voice and TextNow, which are mostly registered in batches and have a user activity rate of less than 5%.
-
Severe resource waste: Without prior filtering via a WS screening tool, directly sending product promotions or discount information to invalid numbers leads to three types of waste: direct costs such as SMS sending fees and API interface call fees; labor costs for manual number screening and following up on invalid leads; and opportunity costs caused by failure to reach valid users.
-
High risk of risk control violations: The WS platform enforces strict risk control on "frequent messaging to invalid numbers." Repeated violations can restrict marketing account functions (e.g., reducing daily sending limits to fewer than 100 messages) or even result in permanent bans, nullifying previously accumulated user resources.
To address this issue, ITG Global Screening (a WS screening tool) resolves invalid number problems at the source through its "full-dimensional number status identification" function:
- Basic status identification: The system automatically verifies whether a number is registered on WS and in normal use, eliminating 100% of empty numbers, disconnected numbers, and canceled accounts to avoid basic invalid deliveries.
- Precise virtual number filtering: Relying on a global virtual number database, it accurately identifies virtual numbers (e.g., Google Voice, TextNow) and temporary registration numbers in India and Southeast Asia, reducing invalid deliveries by over 30% after screening.
- High-risk account marking: It synchronizes WS platform risk control data in real time to mark "high-risk accounts" (e.g., banned accounts, accounts with multiple complaints, accounts with abnormal devices), preventing the enterprise’s own marketing accounts from being compromised due to association with high-risk accounts.
WS user characteristics and number rules vary significantly across global markets. Using a one-size-fits-all screening standard results in poor conversion even for "valid numbers," with specific pain points including:
-
Difficulty adapting to number rules: WS number formats differ by country — for example, U.S. numbers follow the format "+1 + 10 digits," Indian numbers "+91 + 10 digits," and numbers in some European countries "+ country code + 8-9 digits." Ordinary screening tools cannot automatically adapt, easily missing valid numbers due to format errors.
-
Misaligned active periods: Affected by time zones and living habits, WS user active periods vary greatly by region: U.S. users are mostly active from 19:00 to 22:00 (local time); Indian users concentrate their activity from 10:00 to 13:00 and 19:00 to 21:00; Southeast Asian users are active from 10:00 to 12:00 and 19:00 to 21:00. Missing these active periods reduces message open rates by over 70%.
-
Differences in user habits: In the Indian market, users often switch between "primary and secondary accounts" — primary accounts are bound to real information and have high activity, while secondary accounts are mostly for temporary use with low activity. In European and American markets, users value privacy and strongly resist unsolicited marketing messages, which may lead to account reports. Ordinary tools cannot distinguish these differences, resulting in poor delivery performance.
As a global WS screening tool, ITG Global Screening solves these problems through its "in-depth regional adaptation" function:
- Automatic number format adaptation: Built with a number rule database covering over 200 countries and regions, it automatically supplements country codes and verifies number length after upload, avoiding screening omissions due to format errors with an adaptation accuracy of 99%.
- Precise marking of active periods: Combining time zone data and user behavior data of target markets, it marks the "core active period" for each number and provides delivery time recommendations (e.g., "19:00-22:00 local time" for U.S. numbers), helping enterprises accurately grasp the optimal reach timing.
- User habit adaptation strategies: For the Indian market, it automatically identifies "primary accounts" (high activity, bound to real information) and "secondary accounts" (low activity, temporary use), prioritizing primary accounts for delivery. For European and American markets, it filters accounts with "marketing opt-out" marks to reduce the risk of reports.
The core of global marketing is "delivering the right content to the right people." However, traditional WS screening methods can only determine "whether a number is valid" and cannot obtain user tags, resulting in untargeted deliveries:
- Vague user profiles: Inability to distinguish user age, gender, or interests — for example, promoting maternal and child products to "middle-aged and elderly men" results in a conversion rate of less than 1% even if messages are delivered.
- Low demand matching: Inability to identify whether users have relevant product needs — for example, promoting mountaineering gear to "users with no outdoor sports habits" is regarded as spam and may even trigger reports.
- Unclear interaction willingness: Inability to judge users’ tendency to interact — sending limited-time offers to "long-term inactive users who never reply" wastes marketing resources and fails to improve conversions.
When WS marketing shows signs of "sending many messages but receiving few responses," the "tag empowerment" function of a WS screening tool is needed. ITG Global Screening extracts multi-dimensional user tags using AI technology, making precise reach possible:
- Basic attribute tags: Through user WS avatars (real person/anime/landscape), nicknames (e.g., "Lisa_mom2020," "Mike_hiker"), and registration information, it automatically identifies gender (male/female) and age groups (18-25, 26-35, 36-45) with a tag accuracy of over 85%.
- Interest and demand tags: By analyzing WS groups followed by users (e.g., "cross-border e-commerce exchange groups," "maternal and child parenting groups") and interaction content (liked/shared product types, keywords in messages), it generates tags such as "cross-border e-commerce needs," "maternal and child focus," "outdoor sports enthusiasts," and "tech enthusiasts."
- Interaction tendency tags: Based on past user behaviors (whether they reply to messages, click links, participate in polls, or claim coupons), it marks "high interaction tendency," "medium interaction tendency," and "low interaction tendency," prioritizing high-interaction users for conversion-oriented content delivery.
Global WS marketing often relies on seasonal traffic (e.g., Black Friday, Christmas, Southeast Asian Eid al-Fitr, Chinese Spring Festival). However, manual number screening is extremely inefficient, easily causing enterprises to miss optimal promotion timings:
- Severe inefficiency: Manually verifying whether WS numbers are active or target users takes 1-2 days for 1,000 numbers. For 100,000 numbers, it takes 1-2 months to complete screening — completely failing to meet the timeliness requirements of seasonal marketing.
- High judgment errors: Manual screening can only make simple judgments based on "whether there is an avatar" or "whether the nickname is complete," and cannot accurately identify "inactive accounts" (with avatars but no activity for half a year) or "bot accounts" (automatically registered with no real interaction), resulting in a screening accuracy rate of less than 60%.
- Poor process connection: After manual screening, numbers need to be manually organized, entered into CRM systems, and connected to mass messaging tools. These intermediate steps are time-consuming and easily delay delivery, causing enterprises to miss seasonal traffic peaks.
ITG Global Screening solves efficiency problems and adapts to seasonal marketing needs through its "automated efficient processing" function:
- Batch screening acceleration: Supporting batch upload of WS numbers in Excel or CSV format, it completes screening for 100,000 global numbers in just 3-4 hours — over 100 times more efficient than manual work, meeting the rapid screening needs of seasons like Black Friday and Christmas.
- Automatic result classification: After screening, the system automatically classifies numbers into "valid active numbers," "low-active numbers," "invalid numbers," and "high-risk numbers," with user tags (e.g., "26-35 female + maternal and child focus") attached to each category — no manual organization required.
- Seamless multi-system integration: It can directly integrate with CRM systems and WS mass messaging tools (e.g., WhatsApp Business API, intelligent mass messaging robots). Valid numbers after screening are automatically synced to subsequent tools, creating a closed loop of "screening - delivery - follow-up" and reducing manual data transfer time to ensure timely implementation of seasonal marketing.
The WS platform’s risk control rules for marketing behaviors are becoming increasingly strict. Without the risk avoidance capabilities of a WS screening tool, accounts are prone to restrictions, disrupting promotion plans:
- Frequent invalid sending triggers risk control: Frequent messaging to empty numbers or disconnected numbers is deemed "abnormal marketing behavior" by the WS platform, leading to restricted account sending limits (e.g., from 10,000 daily messages to 100).
- Association with high-risk accounts causes collateral damage: Messaging "high-risk accounts" (e.g., banned accounts, accounts with multiple complaints) may lead the platform to classify the enterprise’s account as a "high-risk marketing account," increasing the probability of a ban.
- Non-compliant reach leads to complaints: Sending content to users who have not authorized marketing messages easily triggers reports. Accumulating a certain number of reports results in permanent account bans, losing all previously accumulated user resources.
ITG Global Screening helps enterprises reduce the risk of WS account violations through its "risk avoidance system":
- Pre-filtering of high-risk accounts: It synchronizes WS platform risk control data in real time to mark "banned accounts," "high-complaint accounts," and "abnormal device accounts," automatically excluding them from delivery lists to avoid associated risks.
- Guidance for compliant reach: Aligning with global regional data compliance regulations (e.g., EU GDPR, U.S. CCPA, Southeast Asian personal information protection laws), it automatically filters accounts that have not authorized marketing messages and marks "compliance status" in screening results to guide enterprises in compliant delivery.
- Sending frequency recommendations: Based on the number of valid numbers screened and WS platform rules, it provides reasonable sending frequency suggestions (e.g., sending 100,000 numbers over 3 days, with no more than 35,000 messages per day) to avoid triggering risk control due to high-frequency sending.
The 5 key signals above clearly indicate that in global WS marketing, a professional WS screening tool is not a "dispensable auxiliary tool" but a "core necessity" that determines marketing success.
