In the current context of fierce competition in cross-border trade and overseas marketing, Telegram has become a core channel for enterprises to acquire customers due to its high user activity and strong message reach. However, many enterprises frequently fall into the "invalid number trap" in Telegram customer acquisition—they invest a lot of resources in purchasing numbers and pushing marketing content, only to find that nearly half of the numbers are unreachable invalid numbers. This not only wastes costs but also reduces account weight. In fact, the key to solving the "invalid number trap" lies in professional Telegram number screening: accurately eliminating invalid and non-functional numbers through Telegram number screening allows customer acquisition resources to focus on effective targets; moreover, using ITG Global Screening, a professional system, to conduct Telegram number screening can further achieve "batch detection, accurate identification, and efficient filtering," fundamentally eliminating the interference of invalid numbers and enabling cross-border customer acquisition to completely break free from the "invalid number trap" dilemma.
Many enterprises ignore the importance of Telegram number screening and directly use unscreened numbers for customer acquisition, leading to invalid numbers being mixed into customer lists and triggering a series of chain problems. Specifically, these can be summarized into three major costs:
Without Telegram number screening, enterprises have to pay for "invalid numbers" in terms of number purchase fees and message push fees, but fail to obtain any potential customers. Data shows that in number lists without Telegram number screening, the proportion of invalid numbers generally reaches 35%-50%, meaning nearly half of the marketing investment is wasted.
Case: A cross-border e-commerce company purchased 100,000 Telegram numbers for customer acquisition and directly pushed new product discounts without conducting Telegram number screening. Subsequent statistics showed that 42,000 of these numbers were invalid, and the push cost alone exceeded 80,000 yuan without bringing any effective inquiries. The customer acquisition cost was twice as high as expected.
The Telegram platform is highly sensitive to the "invalid sending rate." Frequent pushes to invalid numbers will lead to the account being judged as a "low-quality marketing account," resulting in a reduction in account weight—message delivery rate drops from over 90% to below 60%, and sending frequency may even be restricted, further affecting the reach of effective customers.
Research: An overseas enterprise did not conduct Telegram number screening, and the invalid sending rate reached 42% due to invalid numbers. One month later, the account's sending frequency dropped from "5,000 messages per day" to "1,000 messages per day," and the number of effective customer acquisitions decreased by 70% directly.
Invalid numbers cannot respond to any marketing content. If they are not eliminated through Telegram number screening, core data such as "opening rate and inquiry rate" will be distorted. Enterprises may mistakenly judge that "marketing content is unpopular" and then adjust incorrect customer acquisition strategies, falling into a vicious cycle.
Case: A foreign trade enterprise pushed product manuals to a list containing 38% invalid numbers. The actual effective opening rate should have reached 30%, but the invalid numbers pulled down the overall opening rate to 18%. The enterprise mistakenly judged that the content was not attractive enough, blindly replaced marketing materials, and missed the opportunity for high-quality customer acquisition.
Targeting the "invalid number pain point" in cross-border customer acquisition, ITG Global Screening has built a Telegram number screening system featuring "accurate invalid number identification, multi-dimensional invalid filtering, and batch efficient processing." Through professional technical means, it completely eliminates invalid numbers and provides protection for cross-border customer acquisition:
- Real-Time Operator Data Connection: The Telegram number screening function of ITG Global Screening directly connects to the real-time databases of operators in more than 200 countries worldwide. It judges whether a number is invalid, suspended, or canceled through "number status verification," with an identification accuracy of up to 99.8%, far exceeding the 80% accuracy of manual screening.
- Dynamic Status Monitoring: Supports the "scheduled re-inspection" function. Some numbers may change from "valid" to "invalid" due to user suspension or cancellation. The system can re-detect monthly or weekly to ensure there are no invalid numbers in the number list at all times.
Case: A cross-border clothing enterprise used ITG Global Screening for Telegram number screening and accurately identified 29,000 invalid numbers from 80,000 purchased numbers. After elimination, the effective delivery rate of pushes increased from 58% to 92%, and marketing costs were directly reduced by 40%.
Telegram number screening by ITG Global Screening goes beyond "identifying invalid numbers"; it can also eliminate other low-value invalid numbers through multi-dimensional screening to further improve the quality of customer acquisition:
- Virtual Number Filtering: Identifies virtual Telegram numbers registered in batches such as Google Voice and TextNow. The user retention rate of such numbers is less than 5%, and they are easily marked as "marketing accounts" by Telegram. Eliminating them can reduce the risk of account risk control.
- Inactive Number Screening: Analyzes the Telegram login frequency and interaction records of numbers in the past 90 days, and eliminates inactive numbers that are "only registered but not active" or "have no operations for half a year" to avoid pushing to numbers with no willingness to respond.
- Risky Number Identification: Connects to the desensitized risk control data of the Telegram platform and screens "accounts with violation records" and "high-complaint accounts." Such numbers not only fail to help acquire customers but may also cause the main account to be restricted, so they need to be excluded first.
Data: An overseas enterprise used ITG for Telegram number screening. In addition to eliminating 35% of invalid numbers, it also filtered out an additional 15% of virtual numbers and 10% of inactive numbers. Finally, the proportion of effective numbers increased from 50% to 85%, and the customer acquisition inquiry rate increased by 2.3 times.
- Large-Scale Batch Processing Capability: ITG Global Screening supports uploading more than 100,000 Telegram numbers at a time. The system adopts distributed computing technology and can complete full-scale Telegram number screening within 1 hour, with efficiency 1,000 times that of manual screening (one person can only screen 500 numbers a day manually).
- Multi-Format Compatibility: Supports uploading of various number formats such as Excel, CSV, and TXT. There is no need to manually adjust the data format; the system automatically identifies number fields after upload, reducing the operation threshold.
- Result Visualization: After screening is completed, a detailed Telegram Number Screening Report is generated, clearly showing "the number and proportion of invalid numbers," "distribution of invalid number types," and "list of effective numbers," facilitating enterprises to quickly connect to subsequent customer acquisition processes.
Case: A cross-border electronic product enterprise previously used a 5-person team for Telegram number screening. It took 20 days to complete the screening of 100,000 numbers, with a misjudgment rate of 12%. After switching to ITG Global Screening, the screening was completed in 1 hour, the misjudgment rate dropped to 0.2%, and labor costs were reduced by 90%.
Using ITG Global Screening for professional Telegram number screening is simple and efficient. It can be completed in only 3 steps, enabling cross-border customer acquisition to completely bid farewell to the "invalid number trap":
- Organize Telegram Numbers: Arrange the Telegram numbers to be screened into an Excel/CSV file in the format of "country code + number" (e.g., +11234567890), and mark auxiliary information such as number sources and procurement channels if necessary.
- Configure Screening Dimensions: Log in to the ITG Global Screening backend, enter the "Telegram Number Screening" module, and check the dimensions to be screened—"invalid number identification" is mandatory, while "virtual number filtering," "inactive number screening," and "risky number identification" are optional. Select flexibly according to cross-border customer acquisition goals (e.g., focusing on cost control or quality improvement).
After clicking "Start Screening," the system automatically connects to the database for detection without manual intervention. You can check the screening progress in real time in the backend (e.g., "60% completed, currently identifying virtual numbers"). The page can be closed during the screening process, and the system will send the Telegram Number Screening Report via email after completion.
If the number of screened numbers is large (e.g., 500,000), the system supports "batch export of results," avoiding waiting for the full amount to be completed and allowing early acquisition of some effective numbers for customer acquisition.
After screening is completed, download the "list of effective numbers" in the report. The list will mark the "status (valid/invalid)" and "invalid reason (invalid number/virtual number)" of each number for enterprises to verify.
Import the effective numbers into the Telegram marketing tool for precise pushes; at the same time, set "scheduled re-inspection" (e.g., once a month) to ensure no new invalid numbers appear in the subsequent customer acquisition process.
Case: A cross-border toy enterprise conducted Telegram number screening with ITG Global Screening every month through these 3 steps. The proportion of effective numbers remained stable at over 90%, customer acquisition costs were reduced by 55%, and cross-border orders increased by 80% within 6 months.
A cross-border home furnishing enterprise was previously trapped in the "invalid number trap" in cross-border customer acquisition:
It purchased 150,000 Telegram numbers every month and pushed directly without conducting Telegram number screening. The proportion of invalid numbers reached 45%, the monthly invalid sending cost exceeded 120,000 yuan, the number of effective inquiries was only over 200, and the customer acquisition ROI was less than 1:1.2.
- Configure Screening Dimensions: Check "invalid number identification + virtual number filtering + inactive number screening" to focus on eliminating invalid and low-value numbers.
- Screening Results: Among the 150,000 numbers, 68,000 invalid numbers, 22,000 virtual numbers, and 15,000 inactive numbers were identified, and finally 45,000 effective numbers were retained.
- Customer Acquisition Implementation: Push "cross-border home furnishing procurement discounts" to effective numbers. Combined with precise content operations, the number of effective inquiries increased to over 1,200, and the customer acquisition ROI increased to 1:3.5.
Through ITG Telegram number screening, the enterprise saved 80,000 yuan in invalid costs every month, the number of effective customer acquisitions increased by 5 times, and the revenue of cross-border business increased by 120% within 3 months.
In the current environment of increasingly fierce competition in cross-border customer acquisition, the "invalid number trap" not only wastes enterprise resources but also hinders the customer acquisition process, becoming a "stumbling block" to the growth of cross-border business. Professional Telegram number screening is precisely the key to blocking the "invalid number trap"—by using ITG Global Screening, a professional system, enterprises can accurately identify invalid numbers and efficiently filter out invalid numbers, ensuring that every penny of customer acquisition investment is used where it matters most, and realizing the precision and efficiency of cross-border customer acquisition.
For enterprises struggling in cross-border customer acquisition, instead of repeatedly trial and error in the "invalid number trap," it is better to immediately use ITG Global Screening to conduct professional Telegram number screening and fundamentally eliminate the interference of invalid numbers. It is believed that as long as Telegram number screening is done well, your cross-border customer acquisition can break free from the dilemma, quickly seize customer resources in the global market, and achieve sustained business growth!
