From Massive Data to Precision Customers: Data Processing Technology and Screening Methodology of Telegram Screening Service

In the wave of digitalization in cross-border business, overseas enterprises often hold overseas user data on a "100,000-level" or "1,000,000-level" scale. However, the invalid accounts and non-target users mixed in the massive data trap enterprises in the dilemma of "having plenty of data but failing to use it effectively". As a professional cross-border user screening solution, Telegram Screening Service can not only efficiently process massive raw data and accurately identify activated and active Telegram accounts, but also lock in high-value customers through scientific screening logic. More importantly, Telegram Screening Service does not operate in isolation. It deeply collaborates with the ITG Global Screening tool, breaking through data dimension limitations and compliance risks, enabling enterprises to quickly dig out "precision customers" from "massive data". This completely solves the core pain point of "casting a wide net but achieving low conversion" in cross-border marketing, and becomes a key data processing tool for enterprises to expand overseas markets.

I. Core Data Processing Technologies of Telegram Screening Service: Solving the Dilemma of Massive Data Processing

Massive raw data often contains duplicate numbers, empty numbers, suspended numbers, and data with format errors (such as missing country codes, abnormal number lengths). These "impurities" seriously affect screening accuracy. Telegram Screening Service adopts "multi-round verification + intelligent deduplication" technology: first, it verifies the number format through regular expressions, automatically correcting format issues such as "missing +86" and "extra spaces"; then, it compares the characteristic values of numbers using hash algorithms to eliminate duplicate data; finally, it connects to the telecom operator database to mark empty numbers and suspended numbers. After 500,000 pieces of Southeast Asian number data provided by a cross-border e-commerce enterprise were cleansed by Telegram Screening Service, the proportion of invalid data dropped from 38% to 12%, laying a foundation for subsequent precise screening.

This is the core technical link of Telegram Screening Service, which achieves precise identification through two methods: first, it connects to the official Telegram API interface to query the activation status of accounts corresponding to numbers in real time, directly marking three statuses: "activated", "not activated", and "cancelled"; second, it uses a behavioral characteristic analysis algorithm to further classify activated accounts into four levels - "highly active (active ≥ 5 times a week)", "moderately active (active 3-4 times a week)", "low active (active 1-2 times a week)", and "inactive (active < 1 time a month)" - by analyzing data such as "login frequency in the past 30 days", "message sending/receiving records", and "group interaction frequency". Data shows that through screening with this technology, the proportion of valid Telegram accounts obtained by enterprises can increase from an average of 45% to 82%. After a cross-border social app was screened by Telegram Screening Service, the conversion rate of user invitation registration increased by 3 times.

Faced with data on a 1,000,000-level or even 10,000,000-level scale, traditional single-machine processing takes several days to complete screening. However, Telegram Screening Service adopts a distributed computing architecture, splitting massive data into multiple "data blocks", assigning them to different computing nodes for parallel processing, and then ensuring efficient collaboration among all nodes through load balancing technology. Taking the processing of 1,000,000 pieces of European number data as an example, the traditional method takes 72 hours, while Telegram Screening Service can complete the entire process from data cleansing to account status identification in only 6 hours. The processing efficiency is increased by 12 times, greatly shortening the cycle for enterprises to obtain precision customers.

In the process of data processing, Telegram Screening Service strictly follows data security specifications and adopts "transmission encryption + storage encryption" dual protection: in the data transmission stage, the SSL/TLS protocol is used to prevent data from being intercepted and tampered with; in the storage stage, the AES-256 encryption algorithm is used to encrypt and store sensitive data such as user numbers and account statuses. Only the data necessary for the screening process is retained, and the raw data is automatically deleted within 72 hours after the screening is completed to avoid data leakage risks. This technical feature makes it fully comply with global mainstream data compliance requirements such as the EU GDPR and Southeast Asia's Personal Data Protection Act.

II. Screening Methodology of Telegram Screening Service: Four Steps to Achieve Precise Conversion from "Data to Customers"

Step 1: Demand Decomposition - Clarifying the Core Characteristics of Target Customers

The first step of Telegram Screening Service is to communicate in depth with enterprises and decompose the vague demand of "finding overseas customers" into quantifiable screening dimensions. For example, the demand of a cross-border beauty enterprise to "expand young female customers in Southeast Asia" will be decomposed into: region (Indonesia, Malaysia, Thailand), age (18-35 years old), Telegram activity level (highly active/moderately active), interest tags (following "beauty reviews" and "affordable skincare" topics), and consumption capacity (having purchased beauty products in the past 3 months). Through demand decomposition, abstract goals are transformed into executable screening conditions for Telegram Screening Service, preventing subsequent screening from deviating from the core direction.

Step 2: Data Integration - Collaborating with ITG Global Screening to Supplement Dimensions

Single Telegram account data is insufficient to fully depict user portraits. Telegram Screening Service collaborates with the ITG Global Screening tool to integrate multi-source data and supplement screening dimensions: first, internal enterprise data, such as historical consumption records in the CRM system and official website browsing tracks; second, third-party compliant data, such as user interest tags on social platforms and shopping preferences on e-commerce platforms; third, geographic data, such as the city corresponding to the user's commonly used IP and local consumption habits. When a cross-border education institution was screening "Chinese learning users in Europe", Telegram Screening Service first located "users in Europe with high Telegram activity", and then supplemented the conditions of "having searched for 'Chinese learning' in the past month" and "having browsed Chinese course pages" through ITG Global Screening. This made the target user portraits more precise, and the subsequent course consultation volume increased by 40%.

Step 3: Hierarchical Screening - Gradually Focusing from "Rough Screening" to "Precise Screening"

Telegram Screening Service adopts a "hierarchical screening" logic to avoid losing target users due to setting too many conditions at once:

Priority is given to screening "Telegram account status (activated) + region (target market)" to eliminate unactivated accounts and users in non-target regions, and quickly narrow down the data scope. For example, a cross-border e-commerce enterprise targeting the Middle East market first screened "users with activated Telegram in Saudi Arabia and the United Arab Emirates", and selected 350,000 basic valid users from 1,000,000 pieces of data.

On the basis of rough screening, "Telegram activity level (highly active/moderately active) + interest tags" are added to screen out users with potential needs. The aforementioned Middle Eastern e-commerce enterprise further screened "highly active users following 'cross-border shopping' and 'discount offer' topics", narrowing the data scope to 180,000 pieces.

Finally, "behavioral data" is supplemented through ITG Global Screening, such as "having cross-border shopping records in the past 3 months" and "having browsed similar products on e-commerce platforms", and 80,000 pieces of high-value customer data are finally screened out. During the hierarchical screening process, Telegram Screening Service outputs the screening results of each level in real time for enterprises to adjust conditions, ensuring that the screening direction meets expectations.

Step 4: Result Verification and Optimization - Dynamic Adjustment to Improve Precision

After the screening is completed, Telegram Screening Service does not directly deliver the results, but first extracts 10% of the sample data for verification: by sending test messages to sample users, it counts indicators such as reach rate, open rate, and response rate. If the reach rate is lower than 80% and the response rate is lower than 15%, it analyzes the reasons and optimizes the screening conditions. For example, after a cross-border game enterprise screened "mobile game users in Southeast Asia", the sample test found that the response rate was only 8%. After investigation, it was found that the "interest tags only included 'games' and did not subdivide 'mobile games'". Telegram Screening Service then supplemented the condition of "following 'mobile game strategies' and 'mobile game gift packs' topics", and the response rate increased to 22% after re-screening. After the verification is passed, the complete list of precision customers is delivered to the enterprise, and a screening report is provided, marking the proportion of users in each dimension, expected conversion potential, and other information.

III. Synergistic Advantages of Telegram Screening Service + ITG Global Screening: Breaking Through Screening Limitations and Enhancing Commercial Value

Telegram Screening Service focuses on the screening of Telegram account status and basic attributes, while ITG Global Screening can supplement data in dimensions such as behavior, consumption, and compliance. The combination of the two upgrades user portraits from "single-dimensional" to "three-dimensional and multi-faceted". After a cross-border logistics enterprise screened "users in Europe and America with active Telegram" through Telegram Screening Service, it used ITG Global Screening to supplement the conditions of "having cross-border logistics needs (such as querying international couriers) in the past 3 months" and "enterprise users (rather than individual users)". Among the finally locked customers, the enterprise cooperation conversion rate reached 30%, far exceeding the 0.5% conversion rate of individual users.

Cross-border data screening faces a complex regulatory environment. Telegram Screening Service and ITG Global Screening collaborate to build a compliance barrier: ITG Global Screening has built-in compliance templates for more than 20 countries and regions around the world, which can automatically verify whether the screening process of Telegram Screening Service complies with local regulations - for the EU market, it checks whether users have signed the Telegram marketing consent form; for the Brazilian market, it confirms whether data is stored locally; for the Middle East market, it checks whether it complies with data usage taboos related to religious culture. An overseas social platform carried out screening in 15 global markets with the assistance of the two, with no compliance complaints, and successfully passed the inspection of local regulatory authorities.

Enterprises that build their own screening teams need to bear high costs such as technology development, data procurement, and compliance consulting. However, Telegram Screening Service provides a "one-stop" solution and charges based on screening results (e.g., 0.5-2 yuan per piece of valid customer data). Moreover, it reduces subsequent marketing costs through precise screening. A comparison by a small and medium-sized cross-border e-commerce enterprise shows that: the monthly screening cost of a self-built team is about 80,000 yuan, and the cost of obtaining valid customers is 15 yuan per person; after using Telegram Screening Service, the monthly screening cost is reduced to 20,000 yuan, and the cost of obtaining valid customers is 5 yuan per person. The cost is reduced by 66%, and the marketing ROI is increased by 2.5 times.
