In Telegram (TG) marketing and customer acquisition, "account bans" are the most frustrating issue for enterprises—hard-earned customer resources become unreachable due to bans, and re-establishing accounts takes a lot of time. Yet many fail to realize that the root cause of frequent account bans often lies in hidden risks from the very beginning of the "number screening" process. Professional Telegram number screening helps enterprises avoid high-risk accounts and reduce invalid operations from the source, preventing triggers for Telegram’s platform risk control. Relying on the Telegram number screening function of ITG Global Screening, enterprises can further leverage risk identification, compliance checks, and precise tiering to keep their Telegram accounts away from ban risks and operate stably. Starting from the core causes of account bans, this article will explain in detail how Telegram number screening helps protect your account security and prevents you from "losing at the starting line."
Many enterprises skip or ignore the Telegram number screening step in their Telegram operations, opting for "blind adding and random messaging" for customer acquisition. These behaviors directly trigger Telegram’s platform risk control rules, resulting in account restrictions or even bans. Specifically, they can be categorized into 3 types of high-risk operations:
- During manual customer acquisition, enterprises often purchase "low-cost number lists" from third-party channels. These lists are mixed with numerous high-risk accounts that are "banned, frequently reported, or have abnormal devices."
- Sending messages to these high-risk accounts without Telegram number screening will cause Telegram to classify it as "associated violation behavior." At best, this restricts messaging functions; at worst, it results in permanent account bans.
- Real Case: A cross-border e-commerce enterprise skipped Telegram number screening and sent products to 50,000 numbers (30% of which were high-risk accounts). Within 3 days, 2 main accounts were banned, losing contact information for nearly 1,000 high-quality customers.
- Invalid numbers (empty, disconnected, or unregistered on Telegram) cannot receive any messages. Frequent messaging to such numbers without Telegram number screening will lead Telegram to label you as a "spammer."
- Telegram has strict thresholds for "invalid send rates" (usually exceeding 20% triggers a warning). The higher the invalid send rate, the greater the risk of account bans.
- Data Reference: Detection via ITG Global Screening’s Telegram number screening shows that enterprises without screening have an average invalid send rate of 45% when messaging 100,000 numbers—far exceeding the 20% warning threshold—with an over 60% probability of account bans.
- Regulations such as the EU’s GDPR and California’s CCPA require explicit user authorization before sending marketing messages. Skipping Telegram number screening to filter compliant users and messaging unauthorized users will trigger user complaints.
- Telegram is highly sensitive to "user complaint rates." A single account with a complaint rate exceeding 5% will be restricted from adding friends or sending messages; long-term high complaint rates lead to permanent bans.
- Common Scenario: A foreign trade enterprise skipped compliance checks and sent products to unauthorized users in the EU. It received over 200 complaints within a week, resulting in a 1-month restriction on its messaging function and missing the procurement peak season.
The Telegram number screening function of ITG Global Screening is not just about "filtering valid customers." It further reduces account ban risks from the source and ensures safer Telegram operations through 3 core capabilities: "risk identification, invalid filtering, and compliance checks":
By connecting to Telegram’s desensitized risk control data, ITG Global Screening’s Telegram number screening accurately identifies 3 types of high-risk accounts and eliminates them directly to avoid associations:
- Ban-associated accounts: Identifies accounts linked to banned devices, IPs, or registration information. Messaging these accounts easily triggers "associated violations"; eliminating them reduces account ban risks by 80%.
- Frequently reported accounts: Marks accounts reported by users more than 3 times in the past 30 days. These accounts have low acceptance of marketing messages, with a complaint rate exceeding 30% after messaging—they must be prioritized for elimination.
- Abnormal device accounts: Detects accounts registered via emulators or multi-account tools. Telegram classifies these as "fake users," and messaging them is easily labeled as "malicious marketing."
A B2B machinery enterprise used ITG screening to eliminate 12,000 high-risk accounts from 80,000 numbers. The subsequent account ban rate dropped from 50% to 5%, significantly improving operational stability.
ITG Global Screening’s Telegram number screening filters out 100% of invalid numbers, controlling the invalid send rate below 5% to stay away from Telegram’s anti-spam mechanisms:
- Empty/disconnected number identification: Verifies via real-time operator data to accurately identify unusable empty or disconnected numbers, avoiding messaging them.
- Unregistered account detection: Connects to the Telegram Business API to real-time check if a number is registered on Telegram; unregistered accounts are eliminated directly.
- Virtual number filtering: Identifies virtual numbers (e.g., Google Voice, TextNow) registered in batches. These numbers have low user retention and are easily labeled as "potential spam accounts" by Telegram.
A fast-moving consumer goods enterprise used ITG screening to reduce its invalid send rate from 45% to 4%—below the 20% warning threshold. No accounts were restricted due to invalid messaging for 6 consecutive months, ensuring stable operations.
ITG Global Screening’s Telegram number screening conducts 2 types of compliance checks to ensure messaging targets meet platform rules and regulatory requirements:
- Authorization status check: Identifies users who have explicitly authorized receipt of marketing messages via Telegram channel subscriptions or form submissions; unauthorized users are excluded directly.
- Regional compliance adaptation: For regulation-sensitive regions (e.g., EU, California), additional checks are performed to confirm if users have agreed to data processing terms, avoiding violations of GDPR and other regulations.
- Complaint history check: Marks users with complaint records in the past 90 days. These users have low tolerance for marketing messages—reconfirmation of authorization is required before messaging.
A cross-border beauty brand used ITG screening to filter compliant users, reducing its messaging complaint rate from 8% to 1.2%—far below the 5% warning threshold. No accounts were restricted due to complaints afterward.
Enterprises can use ITG Global Screening’s Telegram number screening for operations. By following these 4 steps, account ban risks can be reduced to below 5% while maintaining customer acquisition efficiency:
Based on common causes of account bans, determine core risk dimensions for Telegram number screening to ensure no omissions:
- Mandatory dimensions: High-risk account identification (ban-associated/frequently reported/abnormal device), invalid number filtering (empty/disconnected/unregistered), compliance authorization checks.
- Optional dimensions: Regional compliance adaptation (for regulation-sensitive regions), complaint history checks (for users at high complaint risk).
- Example standard: A cross-border e-commerce enterprise targeting European and American markets sets its screening standard as "eliminate high-risk accounts + invalid send rate ≤5% + compliant authorized users ≥95%."
Complete number import and risk checks through the ITG Global Screening backend:
- Import numbers: Organize Telegram numbers to be messaged into Excel/CSV format (including country codes, no special characters) and upload them to the ITG backend.
- Set risk parameters:
- Risk identification: Check "ban-associated accounts," "frequently reported accounts," "abnormal device accounts."
- Invalid filtering: Check "empty/disconnected numbers," "unregistered accounts," "virtual numbers."
- Compliance checks: Check "authorization status checks," "regional compliance adaptation (Europe and America)."
- Launch checks: Click "Start Risk Screening." The system processes automatically—100,000 numbers take only 2-3 hours to complete, generating a "Risk Screening Report."
Focus on the "Risk Screening Report" generated by ITG and adjust messaging plans based on results to reduce ban risks:
- Key indicators to review:
- High-risk account ratio: Must be controlled below 5%; if exceeded, re-audit number sources.
- Invalid number ratio: Must be controlled below 5% to ensure the invalid send rate meets standards.
- Compliant user ratio: Must be ≥90%, and ≥95% in regulation-sensitive regions.
- Strategy adjustments:
- If the high-risk account ratio is high (e.g., 10%): Pause messaging, re-screen number sources, and prioritize numbers from owned channels (official website registrations, exhibition collections).
- If the compliant user ratio is low (e.g., 80%): Send "authorization invitations" to non-compliant users and message them only after obtaining authorization.
Message in batches based on Telegram number screening results and monitor account security:
- Batch messaging: Divide compliant valid numbers into 3-5 batches, with 24 hours between each batch to avoid triggering risk control due to excessive single-batch messaging volume.
- Compliant messaging content: Add an "unsubscribe option" at the start of messages (e.g., "Reply ‘TD’ to unsubscribe if you don’t need this information") to reduce user complaints.
- Real-time monitoring: Check "message success rate" and "complaint rate" via the Telegram account backend. If the success rate is below 80% or the complaint rate exceeds 3%, immediately pause messaging and re-conduct Telegram number screening via ITG.
A SaaS enterprise reduced its account ban risk from 60% to 3% through this process. No accounts were restricted due to violations for 6 months, and the reach rate for valid customers increased to 92%.
- Frequent account bans: An average of 1.5 accounts were banned monthly. Each ban resulted in the loss of over 500 customers, disrupting operational rhythms.
- High invalid send rate: Messaging 100,000 numbers led to an invalid send rate of 48%—far exceeding the 20% warning threshold.
- Persistent high complaint rates: The user complaint rate in the EU reached 9%, with accounts frequently restricted from messaging and missing multiple marketing milestones.
- Significant risk reduction: Telegram number screening eliminated 15% of high-risk accounts and 43% of invalid numbers, filtering out 98% of compliant users. The invalid send rate dropped to 4%, and the complaint rate to 1.1%—no accounts were banned for 6 months.
- More stable operations: Accounts could send messages and add friends normally, with over 3,000 new valid customers monthly. The customer churn rate dropped from 20% to 5%.
- Improved efficiency: Processing 100,000 numbers via Telegram number screening took only 2 hours—100 times more efficient than manual screening—with 70% lower labor costs.
Telegram account status changes dynamically (e.g., users may be reported or cancel accounts later). It is recommended to re-screen existing customers monthly via ITG number screening to eliminate newly added high-risk accounts, avoiding associated violations during subsequent messaging.
Telegram’s risk control rules and regulatory requirements vary by region. For example, the EU requires focus on compliance authorization, while Southeast Asia requires focus on virtual number filtering. Use ITG’s "regional differentiation screening templates" to adapt to risk requirements in different regions.
Free tools can only identify basic invalid numbers and cannot detect high-risk accounts or compliance status. After screening with free tools, the account ban risk remains over 50%. ITG Global Screening conducts full-dimensional risk checks, reducing ban risks to below 5% and saving long-term account re-establishment costs.
Telegram number screening is not a "one-time operation"—it needs to be linked to messaging strategies. After screening, message in batches, monitor the success rate and complaint rate in real time, pause immediately if anomalies occur, and re-screen via ITG to form a "screening → messaging → monitoring → re-screening" security closed loop.
Many enterprises attribute account bans to "strict platform rules" but ignore the source link of "number screening." Skipping Telegram number screening is like driving without checking road conditions—an account ban is only a matter of time. Professional Telegram number screening helps enterprises avoid risks, filter out invalid data, and ensure compliance from the source, serving as the "first line of defense" for account security.
The Telegram number screening function of ITG Global Screening not only improves customer acquisition efficiency but also protects account security, allowing enterprises to operate "both quickly and stably" on Telegram. Remember: Telegram accounts are valuable customer assets for enterprises. Protecting account security starts with proper Telegram number screening every time. Use ITG Global Screening for Telegram number screening now to keep your accounts away from bans, operate stably, and avoid "losing at the starting line!"
