In WhatsApp marketing, "manual number screening" is a major pain point for many enterprises. Faced with tens of thousands or even hundreds of thousands of numbers, operators have to verify validity and mark user attributes one by one. This is not only time-consuming and labor-intensive but also prone to missing high-quality customers due to human errors. Automated tools for bulk WhatsApp number screening are precisely the core solution to this problem: through automated tools, enterprises can quickly complete bulk WhatsApp number screening, eliminate invalid numbers, and lock in precise users. Relying on ITG Global Screening—an automated tool—enterprises can further realize the full-process automation of "bulk screening → user tiering → precise reach," transforming WhatsApp marketing from "inefficient manual work" to "efficient intelligence." Starting from the dilemmas of manual screening, this article will explain in detail how to use ITG Global Screening to achieve bulk WhatsApp number screening and precise reach, helping enterprises bid farewell to tedious manual operations.
When conducting manual WhatsApp number screening, operators face multiple challenges in efficiency, accuracy, and cost. These issues directly restrict marketing effectiveness and are the core reasons for the need to switch to automated tools:
- Verifying one WhatsApp number manually takes 3-5 minutes (including checking registration status, activity level, and whether it is a virtual number). Screening 1,000 numbers requires one person to work continuously for 50-80 hours. For 100,000 numbers, it would take one person 3-4 months.
- During peak marketing periods (e.g., Black Friday, Christmas), manual screening cannot be completed in time, causing enterprises to miss optimal promotion opportunities and waste marketing resources.
- Manual judgment of "whether a user is active" can only rely on simple indicators like "having an avatar or nickname," making it impossible to accurately distinguish between "silent accounts" (with avatars but inactive for half a year) and "truly active accounts." The misjudgment rate exceeds 30%.
- Manual marking of user attributes (e.g., age, interests) relies on subjective judgment, which may incorrectly categorize "users with maternal and child needs" as "users with no needs," leading to the loss of high-quality customers.
- Manual screening requires full-time staff. In a 10-person operation team, about 3 people need to be fully responsible for number screening, accounting for over 30% of labor costs.
- Due to low screening efficiency and high errors, costs for sending messages to invalid numbers (e.g., SMS fees, API calling fees) cannot be saved. The superposition of dual costs drastically reduces marketing ROI.
Whether manual or automated, bulk WhatsApp number screening is a "prerequisite course" for WhatsApp marketing. Its core value is reflected in 3 dimensions, directly affecting the success or failure of marketing:
- After eliminating invalid numbers, marketing messages are only sent to "truly registered, active users," avoiding resource waste on empty numbers and zombie accounts. The reach rate increases from below 30% to over 90%.
- By extracting user tags (e.g., "females aged 25-35 + focusing on maternal and child products") through bulk WhatsApp number screening, the pushed content is highly matched with user needs. The conversion rate is 3-5 times higher than that of unfiltered promotion.
Case: Before conducting bulk WhatsApp number screening, a cross-border maternal and child brand sent new product information to 50,000 numbers with a conversion rate of only 0.8%. After screening, it pushed to 20,000 "precise target users," and the conversion rate increased to 4.2%.
- Reduce direct costs: After eliminating 50% of invalid numbers, SMS sending fees and API calling fees are directly reduced by 50%. Promoting 100,000 numbers can save 10,000-20,000 yuan in costs.
- Lower labor costs: Automated bulk WhatsApp number screening tools (e.g., ITG Global Screening) can process 100,000 numbers in only 1-2 hours, replacing the manual work of 3 people over 3 days. Labor costs are reduced by over 90%.
Data Reference: When enterprises conduct WhatsApp marketing, the "invalid cost ratio" without screening averages 45%. After proper bulk screening, this ratio can be reduced to below 10%.
- Avoid frequent invalid sending: Frequent message pushes to invalid numbers will be deemed "abnormal marketing behavior" by WhatsApp, leading to restrictions on the number of messages the account can send (e.g., from 10,000 messages/day to less than 100 messages/day).
- Filter high-risk accounts: Bulk WhatsApp number screening can eliminate high-risk accounts that are "banned or frequently reported," preventing the enterprise’s own marketing accounts from being banned due to association with high-risk accounts.
Case: A foreign trade enterprise did not conduct bulk WhatsApp number screening, resulting in 2 accounts being banned due to invalid sending within 3 months. After screening, there were no account risk control issues for 6 months, and the promotion plan progressed steadily.
As an automated tool designed specifically for WhatsApp marketing, ITG Global Screening perfectly solves the pain points of manual screening. Its functional features and working principles meet the full needs of bulk screening and precise reach:
- Supports batch upload in Excel/CSV format, processing up to 500,000 numbers per batch. Screening 100,000 numbers takes only 1-2 hours, with efficiency over 100 times higher than manual work.
- Supports automatic background operation. After uploading numbers and setting parameters, no manual monitoring is required. Results are notified via email upon completion of screening.
- Basic screening: Verifies whether a number is registered on WhatsApp, and whether it is an empty/disconnected/virtual number, with an accuracy rate of 99.2%.
- In-depth screening: Extracts user activity (in the past 3/7/30 days), basic attributes (age, gender), and interest tags (e.g., "cross-border e-commerce needs") to provide a basis for precise reach.
- Risk screening: Marks high-risk accounts with "bans, frequent reports, or abnormal devices" to reduce risk control risks.
- Automatic classification of screening results: Automatically files numbers into "valid active accounts, low-active accounts, invalid accounts, and high-risk accounts," supporting Excel export.
- Integration with marketing tools: Can be directly synchronized to WhatsApp bulk messaging tools and CRM systems, realizing an automated closed loop of "screening → reach → follow-up."
- Data access layer: Connects to the official WhatsApp Business API interface to obtain real-time number registration status, activity data, and risk control information, ensuring data authenticity and validity.
- Algorithm processing layer: Analyzes number data through AI algorithms to identify invalid numbers, extract user tags, and evaluate risk levels. The core algorithm accuracy has been verified by tens of millions of numbers.
- Result output layer: Classifies processing results according to user needs, generates visual reports (including validity rate, tag distribution, and risk ratio), and supports synchronization to downstream marketing tools.
ITG Global Screening has an extremely low operating threshold. Ordinary operators can get started in 10 minutes without professional skills. The specific steps are as follows:
- Organize the number list: Arrange the WhatsApp numbers to be screened in the format of "country code + number" (e.g., "+8613800138000," "+11234567890"), and remove special characters such as spaces and hyphens.
- Select screening dimensions: Determine screening dimensions based on marketing needs, such as "basic screening (invalid number filtering) + in-depth screening (activity + interest tags)."
- Log in to the tool account: Register and log in to the ITG Global Screening backend, enter the "Bulk WhatsApp Number Screening" module, and apply for a free trial quota (new users can screen 10,000 numbers for free).
- Upload the number file: Click "Upload File," select the organized Excel/CSV file. The system automatically identifies the number column, no manual matching required.
- Set screening parameters:
- Basic parameters: Check "Eliminate empty/disconnected numbers," "Eliminate virtual numbers," and "Eliminate high-risk numbers."
- In-depth parameters: Select the activity range (e.g., "active in the past 7 days") and interest tags (e.g., "cross-border e-commerce," "maternal and child"), supporting custom tags.
- Confirm task information: Verify the number of numbers, screening dimensions, and estimated time (e.g., "10,000 numbers, estimated time 30 minutes"). Click "Start Screening" after confirmation.
- Monitor progress: Check the screening progress on the "Task Management" page, which supports pausing/resuming tasks. The page can be closed during screening, and the system will continue running in the background.
- View the screening report: After screening is completed, click "View Report" to obtain core data:
- Overall data: Quantity and proportion of valid numbers, distribution of invalid number types (empty number ratio, virtual number ratio), and quantity of high-risk numbers.
- Tag data: Activity distribution of valid numbers and interest tag distribution (e.g., "35% of numbers with maternal and child tags").
- Export and apply: Click "Export Results," select "Export by Category" (export valid, invalid, and high-risk numbers separately), and synchronize valid numbers to WhatsApp bulk messaging tools or CRM systems.
After completing bulk WhatsApp number screening, it is necessary to conduct precise reach based on screening results to maximize marketing effectiveness. The core actions include:
- Basic persona: Clarify users’ basic characteristics (e.g., "females aged 25-35, mainly distributed in the U.S. and India") based on "age, gender, and region" in screening results.
- Behavioral persona: Mark users’ behavioral preferences (e.g., "active in the past 7 days, clicked on 3C product links") based on "activity level and interaction records."
- Demand persona: Judge users’ demand stages (e.g., "inquired about prices, in the decision-making stage") according to "interest tags and consultation records."
- Customization by activity level:
- Highly active users: Push "limited-time offers + product links" (e.g., "Black Friday exclusive 20% off, click to purchase").
- Low-active users: Push "lightweight content + activation benefits" (e.g., "new product review video, get a 10-yuan coupon").
- Customization by interest tags:
- Users with maternal and child tags: Push "new maternal and child products + parenting knowledge."
- Users with cross-border e-commerce tags: Push "supply chain advantages + best-selling products."
- Connect to bulk messaging tools: In the ITG Global Screening backend, directly synchronize the valid number list to WhatsApp bulk messaging tools (e.g., WhatsApp Business API) without manual data transfer.
- Set trigger rules:
- Newly screened valid numbers: Automatically push "welcome messages + exclusive benefits."
- After users click links: Automatically push "product details + consultation entry."
- After users are silent for 3 days: Automatically push "re-engagement messages + limited-time offers."
A cross-border e-commerce enterprise specializing in 3C accessories previously used manual screening. Screening 100,000 numbers required 3 people to work for 5 days, with 45% of numbers being invalid. The marketing conversion rate was only 1.2%, and the account was once restricted due to invalid sending.
- Used ITG Global Screening to process 100,000 numbers in 1.5 hours, eliminating 42,000 invalid numbers, 13,000 virtual numbers, and 5,000 high-risk numbers, retaining 40,000 valid numbers.
- Tiered valid numbers into "highly active with 3C needs (12,000), moderately active with general needs (20,000), and low-active to be activated (8,000)" based on "activity level + interest tags."
- Pushed "Black Friday discounts + local warehouse shipping in the U.S." to highly active users, achieving a conversion rate of 5.8%.
- Pushed "3C new product reviews + full-reduction coupons" to moderately active users, achieving a conversion rate of 3.2%.
- Overall marketing costs were reduced by 55%, no account risk control issues occurred, and monthly orders increased by 2.3 times.
- Data security: Choose compliant automated tools (e.g., ITG Global Screening) to ensure the tool does not store user privacy data and uses HTTPS encryption during transmission.
- Compliance: Ensure screened numbers have authorized receipt of marketing information, especially for regions covered by the EU GDPR, to avoid non-compliant reach.
- Regular updates: Number status changes over time (e.g., user cancellation, disconnection). It is recommended to re-screen with automated tools every quarter to maintain number quality.
- Question 1: Slow screening speed?
Solution: Check the network environment, avoid uploading oversized files at once (it is recommended to upload no more than 100,000 numbers at a time), or contact customer service to upgrade server permissions.
- Question 2: Valid numbers misjudged as invalid?
Solution: Submit a "Number Review Application" in the ITG Global Screening backend. Customer service will conduct manual review within 24 hours and adjust algorithm parameters.
- Question 3: Unable to synchronize to bulk messaging tools?
Solution: Confirm that the interface between the bulk messaging tool and ITG Global Screening has been authorized, or export the Excel file for manual import. Customer service provides one-on-one docking guidance.
