Complete Guide to Telegram Active Data: Definition, Window Selection, and Efficient Outreach Strategies

In overseas user acquisition and community management, Telegram number quality directly determines outreach effectiveness. Many assume that a “working number” is enough, but what truly influences DM delivery rate and group join rate is Telegram active data. Even if you have millions of valid numbers, a large portion of those users may have long been offline—your messages either vanish into the void or get flagged as spam. This article starts from the definition of active data, breaks down the logic behind choosing 7-day, 15-day, and 30-day active windows, and provides a complete operational workflow from number generation to active filtering. Whether you’re an e‑commerce operator or TG community promoter, you’ll find actionable strategies here.

What Is Telegram Active Data? Why Is It More Important Than “Valid Numbers”?

Three Levels: Registration, Valid, Active

Level	Meaning	Detection Method
Registration (sign‑up detection)	Whether the number has registered on Telegram	Verify via API if the number exists in TG’s system
Valid	Beyond registration, the account is not banned and hasn’t been inactive for too long (often platforms mark it as “valid” but cannot directly judge online frequency)	Some tools combine API returned status
Active	Has been online or sent a message within a certain time window (e.g., 7 days, 15 days, 30 days)	Analyze account’s last activity time via offline requests or specific interfaces

Simply put: Registration means “has an account,” valid means “account can receive messages,” active means “this person has been using it recently.” In overseas marketing, what we truly need is active data—only active users are likely to read your message, click a link, or complete a conversion.

How Active Data Affects Reach Rate and Conversion Rate

Suppose you have 100,000 “valid” TG numbers, but only 40,000 have been active in the last 7 days. If you send DMs to all of them, the 60,000 inactive numbers likely won’t receive the messages (or will leave them unread for a long time). In contrast, active numbers have much higher open rates and reply rates. Focusing on active data means achieving higher ROI with fewer messages.

What Telegram Active Windows Are Available? How to Choose Between 7‑Day, 15‑Day, and 30‑Day Windows?

TG doesn’t publicly disclose each user’s last online time (it only shows “last seen: x minutes/hours/days ago”), but filtering tools can detect whether an account has been active within a specified number of days. Common preset windows are 7 days, 15 days, and 30 days.

7‑Day Active Window: Best for High‑Frequency Interaction Industries

• Use cases: Marketing that requires immediate feedback (flash sales, live stream promotions, urgent notifications); industries with young, high‑frequency users (gaming, cryptocurrency).
• Advantages: Extremely high reach rate, nearly guaranteeing the recipient is a heavy TG user.
• Disadvantages: Smallest pool—may only filter out 20%–30% of the total numbers.

15‑Day Active Window: A Balanced Choice Between Quantity and Quality

• Use cases: Most overseas user acquisition scenarios (cross‑border e‑commerce, independent store traffic, community fission).
• Advantages: Good balance between number volume and reach rate. Users active within 15 days are still high‑frequency users, but the pool is about 50% larger than the 7‑day pool.
• Disadvantages: Some users may have started reducing usage, but overall effect is not harmed.

30‑Day Active Window: Maximize Pool Size but Slightly Lower Instant Reach Rate

• Use cases: In the acquisition phase, to cover as many potential users as possible; or when your content doesn’t require an immediate reply (e.g., channel subscriptions).
• Advantages: Largest active number base—can reach 60%–70% of all numbers.
• Disadvantages: Reach rate is slightly lower than 7‑day/15‑day windows because some users only go online occasionally.

How to choose? It’s recommended to run a small‑scale test first: for the same batch of numbers, filter 7‑day, 15‑day, and 30‑day active data separately, then compare message delivery rates or group join rates. Most teams default to 15 days and fine‑tune based on conversion data.

How to Batch Acquire TG Active Data? Manual vs. Tool Comparison

Method	Operation	Efficiency	Accuracy	Suitable Scale
Manual marking	Manually record numbers’ recent online times (check “last seen” in TG)	Extremely low—100 numbers may take 30 minutes	High (human judgment)	Tens
API script	Write your own Python script to call the TG API	Medium—must handle rate limits and proxies	Depends on script quality	Hundreds–thousands
Professional filtering platform	Submit a number list; the platform automatically detects and returns active data	Very high—millions completed in hours	High—uses multi‑dimensional validation	Tens of thousands–millions+

For daily operations, manual marking is unsuitable for large‑scale tasks. If you need to process hundreds of thousands or even millions of TG numbers each month, it’s best to use a professional filtering platform like KK-DATA. Such platforms typically offer 7/15/30‑day active window options and support cross‑platform filtering (WhatsApp, iMessage, etc.), saving you the trouble of building your own system.

TG Active Data Filtering in Practice: Complete Workflow from Number Generation to Activity Detection

The following example uses KK-DATA to demonstrate the entire pipeline. KK-DATA supports a one‑stop workflow: “number generation → multi‑platform filtering → result export.”

Step 1: Prepare the Number Source (Generate Randomly or Import Your Own List)

• Global number generation: If you don’t have existing numbers, you can randomly generate numbers from 240+ countries/regions in the KK-DATA console. Generation is free; filtering charges per query.
• Custom import: If you already have a CSV list of numbers, upload it directly to the platform. It supports a deduplication warehouse—the system automatically skips previously checked numbers to avoid repeat charges.

Step 2: Set the Active Window and Submit the Filtering Task

1. Log in to https://app.kkdata.cc/ and go to the “Filtering Task” page.
2. Select the number source (generated numbers or uploaded file).
3. Choose the platform as Telegram and then check the detection types:
   • TG registration (sign‑up detection)
   • TG valid (account is valid)
   • TG active (key! Choose 7/15/30 days or custom)
   • Optionally add TG gender identification (avatar recognition) or TGID export.
4. Preview the estimated cost (charged per detection query; see console for unit price).
5. Submit the task. The platform will notify you via Telegram when it’s done.

Step 3: Export Filtered Results and Deduplicate

• After the task completes, export CSV/TXT from the results page. Fields include: number, active status, last active window, TGID, gender (if available).
• Use the platform’s built‑in data deduplication warehouse to import this result into the dedup pool. Next time you submit new numbers, the system will automatically skip already processed numbers, avoiding duplicate charges.

The entire process—generate → filter → dedup → export—is completed within the same console without switching tools.

Application Scenarios and Strategies for Active Data in Overseas User Acquisition

1. Precise Community Recruitment

Use 7‑day active data to filter high‑frequency TG users, then send group invites or DMs with join links. These users are more willing to join new communities and participate in discussions.

2. Direct Message Marketing

Send marketing messages (product introductions, coupons, event notifications) to users from 15‑day active data. Since they are recently active, the messages are more likely to be read, and the risk of account bans is relatively low (avoid batch sending; use progressive delivery).

3. A/B Testing User Personas

Filter both 7‑day and 30‑day active data simultaneously, send different copy to each group, and compare conversion rates. You may find that 7‑day users are more sensitive to “limited‑time” content, while 30‑day users respond better to “long‑term value” content.

4. Clean Your Existing Customer Database

If you have a historical customer list (phone numbers), use TG active detection to remove inactive numbers and retain only recently active customers for repurchase re‑engagement. This significantly reduces the cost of invalid sends.

5 Considerations When Choosing a TG Active Filtering Tool

1. Active detection accuracy: Different tools have different algorithms. Look for platforms that publish technical explanations or user reviews. KK-DATA uses multiple validations (combining API returns and offline behavior) for higher accuracy.
2. Window configurability: Does the tool support 7/15/30 days or custom windows? Fixed‑window tools lack flexibility. Choose a platform that offers multiple options.
3. Data security: Will the number data be retained? Can you delete it after export? Choose platforms with privacy commitments (e.g., KK-DATA supports deleting source data after task completion).
4. Billing transparency: Is per‑query billing clear? Can you view balance details? Avoid hidden fees.
5. Customer support: Can anomalies be resolved in a timely manner? It’s best to choose a platform that offers two‑way contact (e.g., TG bot + human support) for quick responses.

Frequently Asked Questions

Q: Does TG active detection notify the target?
A: No. Active detection is silent—it does not send any notification to the target user or change their account status. You can confidently submit numbers.

Q: Can I customize the active window, for example, to detect users active within 3 days?
A: Most professional filtering platforms (like KK-DATA) preset 7‑day, 15‑day, and 30‑day options and do not fully support arbitrary customization. However, you can achieve a similar effect by combining filters: e.g., first filter 7‑day active, then exclude certain groups. If you need a more precise time range, please contact the platform support directly.

Q: What is the maximum number of numbers I can submit in one filtering task?
A: KK-DATA supports up to about 1 million numbers per single task. If you exceed that, please submit in batches. Note that more numbers will extend the processing time.

Q: How is the filtering balance deducted? By submitted numbers or by queries actually performed?
A: Deduction is based on actual queries performed. For example, if you submit 100,000 numbers and only 90,000 are successfully detected (10,000 skipped due to format errors or not being TG numbers), you are charged only for 90,000. The unit price is shown in real time on the console; there is no subscription plan—pay as you go.

Q: If a task fails midway, will the balance be refunded?
A: If the task fails due to platform system issues (e.g., server anomaly), the deducted fee will be refunded to your balance. If the failure is caused by an incorrect number file format submitted by the user, a refund may not be possible (see detailed rules at https://docs.kkdata.cc/ or contact support).
