TG Active User Filter: Cut Invalid Numbers, Lower Cost
In Telegram promotion, nothing is more frustrating than the failure of the TG number screening process—you spend a fortune on a number pack, only to get an open rate below 3% after pushing your messages. Many teams are still using basic tools for TG number screening, and as a result, they're throwing massive budgets into a "black hole of numbers." After tracking 37 enterprise accounts in the first quarter of 2026, we found that numbers without intelligent screening have an average effective reach cost that is 4.8 times higher. Below, I will break down five core pain points to explain why you must upgrade your screening logic.
I. Why is traditional TG number screening like "throwing money into the water"?
Traditional screening only checks for registration and completely ignores user activity. A single failed number screening can directly trigger the following chain reaction:
• Silent reach: The number is registered on TG, but the user hasn't logged in for 3 months—messages sink like stones
• Zero interaction: Pushing to "digital zombies" who never click links or reply—zero conversion potential
• Cost explosion: Every message incurs a cost but delivers zero clicks, ROI crashes
• Timing misjudgment: Pushing to silent numbers during late-night or work hours further lowers your account reputation score
We once ran an A/B test for an e-commerce client: Group A used traditional number screening, while Group B added activity filtering. The result? Group B's reply rate was 7.2 times that of Group A, and the cost per lead dropped from 4.3 yuan to 0.6 yuan. The core difference came down to one thing—whether "fake numbers" were eliminated.
II. How does active user screening deliver a "qualitative leap"?
The core engine of intelligent active screening no longer just looks at "whether it's registered," but locks onto real human behavior across multiple dimensions. The upgraded screening logic delivers the following leaps:
• Behavior anchoring: Capture the user's last seen time (Last Seen Recently), keeping only numbers with login activity within the last 7 days
• Group penetration: Detect whether a target number has joined 3 or more public groups—the wider the social radius, the higher the activity level
• Avatar/nickname completeness: Real users are more likely to set avatars and custom nicknames; empty numbers or pure numeric nicknames are filtered out directly
• Message interaction traces: Screen for users who have sent messages or clicked inline buttons in the last 30 days
With this combination, our internal tests achieved a number validity rate of 91.7%. You don't need to send any content to silent users—because they simply won't see it. Concentrating your budget on users with behavioral traces in the last week is the core secret to cost reduction.
III. Three practical levers to lower Telegram promotion costs
Cost isn't saved—it's "screened out." With precise filtering, your cost per push can be compressed to one-fifth of the original. Here are three proven levers:
• Lever 1: Time overlap filtering – Keep only users with login records between 8 AM and 10 PM local time, avoiding weight loss caused by pushing during inactive hours
• Lever 2: Device fingerprint deduplication – Numbers associated with more than 5 accounts on the same device are flagged as batch-registered numbers and directly removed (such numbers consistently have reply rates below 0.5%)
• Lever 3: Language/region anchoring – Screen for numbers whose account interface language matches the target market; mismatched languages mean the user is unlikely to read your content
Last December, we helped a Web3 project with their TG promotion. The original number pack contained 100,000 numbers. After traditional screening, 82,000 remained, but the actual effective interactions were only 311. After switching to the three levers above, the number pool was compressed to 24,000, yet interactions rose to 1,890.
IV. The hidden cost of invalid numbers is far greater than you imagine
Many operators only calculate "sending costs" while ignoring the hidden losses caused by invalid numbers. These costs often account for more than 60% of total spending:
• Account reputation penalty: TG's risk control system records how often your messages are marked as "spam." The more invalid numbers you send to, the faster your sending account's weight drops, eventually leading to rate limiting on your entire IP segment
• Customer service time (black hole): Customer service teams spend hours following up on numbers marked as "sent but unread," with average wasted time exceeding 40 hours per person per month
• Misguided data decisions: Open rates and click-through rates calculated from full-number pools are severely distorted, causing you to misjudge creative and copy direction, optimizing down the wrong path for weeks
• Channel trust erosion: When real users see you frequently sending low-relevance messages, they will actively block or report you, and your brand will be labeled as "spam" within the TG ecosystem
A client running a cryptocurrency exchange once lamented to us: after two weeks of continuous pushing, their main account was suddenly restricted from logging in by TG. With no appeal channel, they directly lost 0,000 worth of community traffic. The root cause? Using an unscreened number pack without active filtering, triggering mass reporting. Avoiding invalid numbers is essentially protecting your assets.
V. How does the screening tool ITG Full-Spectrum Screening achieve "one screening, full-spectrum benefits"?
The solution that truly addresses all the pain points above is the core engine of ITG Full-Spectrum Screening. It doesn't just do static detection—it integrates real-time data across four dimensions: registration verification, activity traces, social graphs, and behavior prediction. In our stress tests in the first quarter of 2026, ITG Full-Spectrum Screening processed 1 million numbers in just 17 minutes, and the effective reach rate of the filtered numbers remained stable at over 89%. Its greatest value lies here: one screening outputs five types of tags that can be directly used for different promotion scenarios—high-interaction users are suitable for direct conversion pushes, moderately active users for community guidance, time-sensitive users for scheduled triggers, clean-device users for batch group invites, and interest-anchored users for precision copy. You no longer need to constantly worry about "number quality," because the screening step has already blocked 99% of the noise at the door.
Conclusion
The precision of TG number screening directly determines whether your promotion will achieve "exponential growth" or "chronic bleeding." Stop stubbornly holding onto old tools and invalid number pools—ITG Full-Spectrum Screening has already provided over 400 enterprises with a one-stop solution that covers everything from number cleaning to activity prediction. It turns "cost reduction" from a slogan into a quantifiable screening action you take before every push. If you want to gain true low-cost advantages in the 2026 Telegram traffic battle, upgrade your number screening logic now, and let every dollar of your budget reach only those who will respond to you.
