Ultimate Guide to TG Activity Detection: Telegram Active Number Filtering, Activity Window Selection, and Reach Strategy

For overseas marketing and community operation teams, obtaining a large volume of valid Telegram numbers is only the first step. The real key to determining marketing effectiveness and cost lies in accurately filtering out truly active users from this pool. Simply checking whether numbers have registered for Telegram may lead you to pay detection fees for a large number of long-inactive “zombie accounts.” Worse still, sending messages to these numbers yields no response and may trigger the platform’s risk control mechanisms, resulting in account restrictions.

TG Activity Detection is specifically designed to solve this problem. It goes beyond merely checking registration status and focuses on the activity status of a number within a specific time window—whether the user has come online, sent, or received messages. This article systematically outlines the core concepts, operational procedures, and practical strategies for TG activity detection, helping you allocate your limited budget to “real people.”

What is Telegram Activity Detection? – Criteria for Defining an Active Account

Telegram activity detection essentially determines whether a Telegram account is “active” based on data such as the user’s last online time and message sending/receiving behavior. The detection result is usually presented as “whether the specified activity window is met.”

For example, if you select a “7-day activity window” for detection, the system will check whether the number has come online or sent/received messages in the past 7 days. If the last activity was 8 days ago, it will be judged as “inactive.”

Active Number vs. Valid Number vs. Registered Number: What’s the Difference?

These three concepts are most commonly confused in overseas operations, yet their marketing value differs significantly.

Detection Type	Criteria	Marketing Value	Typical Use
Registered Number	Checks if the number is registered for Telegram (valid number)	Low	Basic data cleaning, excluding unregistered numbers
Valid Number	Checks if the number can receive messages (account not deleted or banned)	Medium	Preliminary screening of reachable audience
Active Number	Checks if the number has online/message behavior within a specified time	High	Precision targeting, reducing无效 sends, improving conversion

Simply put: Registered numbers are people on your list who “have an account”; Valid numbers are accounts that are still usable; Active numbers are users who have recently been “playing” on Telegram. In terms of marketing cost and effectiveness, the ROI of active numbers far exceeds the other two.

Data Sources and Determination Mechanism for Telegram Activity Detection

Activity detection data mainly comes from Telegram server behavior logs, including but not limited to:

• User’s last online time (although privacy settings may hide it, detection tools can infer using other methods)
• Frequency and time distribution of message sending/receiving
• Group/channel interaction records

Professional number screening platforms (such as KK-DATA) use legitimate query interfaces to integrate the above data for accurate judgment. Note: Due to privacy protection, some users’ “last seen” time may be hidden. In this case, detection tools will adopt alternative strategies (such as analyzing message interaction cycles) to assist judgment, ensuring that active status is not misjudged.

Why Do Overseas Marketing Teams Need Dedicated TG Activity Detection?

Many inexperienced operators fall into a common misconception: first run a registration check, get tens of thousands or even hundreds of thousands of valid numbers, and then start mass spamming. The result is often high send rates but extremely low open rates, and even account bans soon.

The reason: a registration check only tells you “there is an account here,” but not “whether the account owner is still using it.” A large number of abandoned accounts (long-term dormant, no interaction) occupy your reach slots, dragging down overall data and easily getting you flagged by Telegram for high-frequency invalid sends.

Performing TG activity detection brings three direct benefits:

1. Reduce invalid costs: Only pay for numbers that have real reach value, avoiding the awkward situation of “testing 1000 only to find 100 valid.”
2. Lower the risk of account suspension: Sending messages to active users significantly reduces the probability of being reported and the likelihood of triggering risk control due to massive invalid sends.
3. Improve conversion efficiency: Active users are far more likely to open and reply than silent users. The same promotion copy can achieve 2-3 times higher reply rates when reaching active numbers.

How to Choose the TG Activity Detection Window? – Applicable Scenarios for 7/15/30 Days

The choice of activity window directly determines the quantity and quality of the filtered results. There is no absolute “good” window—only the one that best suits your current marketing goals.

7-Day Activity Window: Best for High-Timeliness Marketing Scenarios

Applicable scenarios: Limited-time flash sales, flash deal events, short-term live stream invitations, holiday blitz promotions.

Advantages: Users active within 7 days have the highest reply rates—they are in a high-frequency usage phase and are most likely to take action after seeing your message. For time-sensitive activities, the 7-day window ensures your message is seen during the user’s peak attention period.

Disadvantages: Covers the fewest numbers. Some users may simply be busy this week and come back next week; the 7-day window will exclude them. If your campaign lasts longer (e.g., over a week), a 7-day window may be insufficient.

Recommended budget allocation: 10%~20% of total budget for high-priority limited-time events.

15-Day Activity Window: Best Balance for Community Operations and Moderate Reach

Applicable scenarios: Community invitations, new product launches, long-term online recruitment, content subscriptions.

Advantages: Covers the vast majority of regular active users (those who log in at least once every two weeks), achieving a good balance between coverage and response rate. This window is suitable for most non-urgent promotion needs.

Disadvantages: Compared to the 7-day window, reply rates may drop slightly, but not significantly. This is a “steady” choice.

Recommended budget allocation: 60%~70% of total budget for routine promotions as the main window.

30-Day Activity Window: Long-Term Prospect Pool and Broad Reach Strategy

Applicable scenarios: Brand exposure, EDM-style warm-ups, user surveys, pre-purchase water storage periods.

Advantages: Widest coverage, encompassing most monthly active users. For scenarios that do not require immediate response, such as building brand awareness or long-term user cultivation, the 30-day window maximizes reach base.

Disadvantages: Reply rates are relatively low (some users may not have been online in the past month, or log in very infrequently). These users are better suited as a “prospect pool” rather than an “instant conversion pool.”

Recommended budget allocation: 10%~20% of total budget for long-term customer acquisition or brand water storage.

If you need to run multiple campaigns targeting different layers, consider a tiered strategy: first use the 30-day window for broad filtering, then focus on users active in the 15-day/7-day windows for key reach.

Practical Workflow for TG Activity Detection – From Number Preparation to Result Export

Below is a standard workflow for TG activity detection using a professional number-screening platform (e.g., KK-DATA).

Step 1: Number Preparation and Import

• Ensure correct number format: international format (e.g., starting with +86, or directly 86138xxxxx), one per line, plain text.
• It is recommended to deduplicate first. Duplicate numbers will be detected repeatedly, wasting balance.

Step 2: Select Detection Type and Activity Window

• Create a task in the console and select the Telegram platform.
• Choose TG Active from the detection types.
• Select the activity window: 7 days / 15 days / 30 days (based on your marketing goals).
• The system will automatically estimate the cost of this task (see console).

Step 3: Check Balance and Submit Task

• Ensure your account balance is sufficient to cover the task cost.
• Submit the task. A single task can process up to approximately 1 million numbers.

Step 4: Wait for Task Completion and Receive Notification

• Processing time depends on the number of numbers and server load. For 10,000 numbers, it usually completes within a few minutes.
• You can enable Telegram notifications to receive instant alerts when the task is done.

Step 5: Export Result Data

• After the task is completed, view the results in the console.
• Support for exporting CSV, TXT, etc. Some platforms (e.g., KK-DATA) also export TGID, convenient for integration with automation tools.
• The export result will mark which numbers are “active” and which are “inactive.”

Reach Strategies and Effectiveness Comparison for Different Activity Windows

With the same number list, selecting different activity windows should lead to adjusted reach strategies.

Activity Window	Typical Reach Strategy	Recommended Message Frequency	Expected Reply Rate	User Profile Characteristics
7 days	Limited-time coupons, flash sale links, campaign countdowns	1-2 times during campaign	High (15%~30%)	High-frequency users, sensitive to instant information
15 days	Community invitations, product feature introductions, member benefits	Once per week	Medium (8%~15%)	Regular active users, good interaction habits
30 days	Brand stories, industry news, user surveys	2-3 times per month	Low (3%~8%)	Light users, require long-term cultivation

Practical advice:

• For numbers active in the 7-day window, message copy should emphasize urgency and direct benefits, e.g., “First 50 orders get 50% off.”
• For numbers active in the 15-day window, copy should focus on value delivery and social proof, e.g., “Join our community of 2000+ users.”
• For numbers active in the 30-day window, copy should center on brand awareness and informational value, e.g., “Understand overseas trends in 2025 in one article.”

According to industry experience, choosing the right activity window can increase reply rates by 30%~50%. This is not empty talk—when you stop sending messages to cold numbers, every outreach brings you closer to real users.

Common Misconceptions and Precautions for TG Activity Detection

1. Misconception: All active numbers will reply at high rates. Reality: Active does not equal interested. Activity only indicates recent online behavior, not a need for a specific product. Therefore, activity detection is only the first step; subsequent targeted content strategies are equally important.

2. Misconception: Smaller windows are always better. Reality: The 7-day window offers the highest reply rates but covers the fewest users. If your campaign cycle is longer (e.g., continuous community recruitment), a 15-day or 30-day window may be more appropriate. Choose based on campaign duration and budget.

3. Misconception: One detection is enough. Reality: User activity is dynamic. Someone inactive today may return next week. It is recommended to retest the same prospect pool monthly or quarterly to keep the number pool fresh.

4. Misconception: Start sending aggressively right after detection. Reality: Even after filtering active numbers, you must abide by Telegram’s terms of service. Avoid bulk homogeneous spamming. Design warm, personalized messages and control sending frequency (e.g., no more than 30 messages per hour, with intervals of at least 5 seconds between each).

5. Important reminder: Activity detection itself is a query on number status and does not involve sending messages, so it will not directly cause account bans. However, using the filtered results for illegal spamming is at your own risk.

How to Choose a TG Activity Detection Tool? – Feature Comparison and Evaluation Dimensions

The quality of number-screening tools on the market varies. When selecting one, focus on the following 6 core dimensions:

1. Number of activity windows: Does it support multiple windows like 7/15/30 days? More windows mean more flexible strategy configuration.
2. Single batch processing limit: Can it handle your business scale? Large teams should prefer platforms that support tasks of millions of numbers.
3. Data export formats: Does it support CSV, TXT, TGID, etc.? TGID export is extremely important for subsequent automation operations.
4. Billing method: Is it pay-per-number? Are there mandatory packages? Pay-per-use is more flexible for teams with fluctuating budgets.
5. Cross-platform detection capability: Can it simultaneously detect TG, WhatsApp, iMessage, RCS, etc.? One platform handling multiple platforms significantly improves efficiency.
6. Customer support response speed: When encountering technical problems, can you quickly contact support via instant tools like Telegram?

Take KK-DATA as an example. Its performance in the above dimensions:

• Activity windows: Supports 7 days, 15 days, and 30 days, meeting various scenario needs.
• Single batch limit: Approximately 1 million, suitable for medium-to-large teams.
• Export formats: CSV, TXT, as well as TGID and WSID, convenient for connecting with automation tools.
• Billing method: Pay-per-number, no subscription packages, pay as you go, recharge with USDT.
• Cross-platform: Simultaneously supports Telegram, WhatsApp, iMessage, RCS, and other platforms.
• Customer support: Provides instant support via Telegram customer service (@kkdata_cc).

Of course, you can evaluate based on your own business characteristics, but prioritize platforms that support multiple activity windows, pay-per-number billing, and flexible data export.

Frequently Asked Questions

Q: What exactly does the activity window mean in TG activity detection?
A: The activity window refers to the time range within which the detection tool determines whether a number is active. For example, selecting “7-day active” means the system will check whether the number has been online or sent/received messages in the past 7 days. Common options are 7 days, 15 days, and 30 days.

Q: Which yields better marketing results: 7-day active or 30-day active numbers?
A: Effectiveness depends on your marketing goals. 7-day active numbers are suitable for time-sensitive campaigns (e.g., limited-time promotions), offering higher response rates but smaller coverage. 30-day active numbers cover a wider range, ideal for brand exposure and long-term user cultivation, though some numbers may be inactive. It is recommended to combine both based on budget and purpose.

Q: After running TG registration detection, do I still need to run activity detection?
A: Yes. Registration detection only tells you whether the number is registered for Telegram (valid number), but cannot distinguish long-term inactive zombie accounts. Activity detection further filters out high-value numbers with recent interaction, significantly reducing invalid send costs.

Q: Will activity detection cause my Telegram account to be banned?
A: Activity detection itself is just a query on number status and does not involve sending messages, so it will not directly cause a ban. However, using the filtered active numbers for mass spamming or harassment may violate Telegram’s terms of service. Please operate compliantly.

Q: What export formats are available for activity detection results?
A: Most number-screening platforms support CSV and TXT exports. Some platforms (e.g., KK-DATA) also support exporting TGID, WSID, and other identifiers, making it easy to connect with automation tools.
