How long does the Telegram screening result last? Best practices for rescreening rhythm and data refresh

In the daily operations of overseas customer acquisition, many teams will encounter a typical problem: a batch of Telegram active numbers screened out last week have a significant drop in open rate when sending messages this week. Is it because the customer stopped reading, or the number itself has expired? The answer is often the latter - Telegram screening results are not “tested once and valid forever”. The status of the number (active, activated, blocked) will change over time. If you do not rescreen regularly, the accuracy of your marketing reach and conversion rate will continue to decrease.

This article will start from the concept of “shelf life” and combine it with the functions of the KK-DATA platform to help you develop a scientific re-screening rhythm for Telegram screening results, so that every contact is targeted at truly valuable users.

What is the “shelf life” of Telegram filter results?

Shelf life refers to the time window from when you complete the number screening task to when the actual status of the number changes significantly. For example, if you screen out a batch of Telegram numbers that are “active in the past seven days” on Monday, by next Monday, a considerable proportion of users in these numbers may no longer be active, have canceled their accounts, or have even been banned by the platform. If this batch of data is used for marketing at this time, the reach efficiency and response rate will drop significantly.

Understanding the shelf life is a prerequisite for planning the re-screening rhythm. The shelf life of different detection types (such as only detection of activation, detection of active detection, combined detection of gender) varies greatly. The activity data has the shortest shelf life, and the activation status is relatively long, but the overall trend is that the closer to the present, the more accurate the data is.

Why does Telegram number data need to be refreshed regularly?

From a practical operational perspective, regular rescreening is not an “optional” option, but a necessary action to maintain customer acquisition results. The reasons come from three dimensions:

1. User cancellation and account loss: Telegram users may actively cancel their accounts due to privacy concerns, uninstalling apps, or switching to other platforms. These numbers may still be “open” or “active” when you screen them, but they may become completely invalid after a month.
2. Platform banning mechanism: Telegram will freeze or ban accounts that violate group messaging or are reported. The valid numbers you screen may be invalid due to the recent bad behavior of the account owner - these numbers are not only unreachable, but may also lower the reputation of your domain name/number.
3. Natural expiration of active window: Activity detection relies on “recent online time”. If you screen for numbers that are “active within 24 hours”, even if the owner of the original number logs in half an hour later, your data will no longer be accurate. More commonly, users will change their usage habits (for example, from being active during the day to being active at night), causing your marketing time window to be misaligned.

From a quantitative perspective, about 10%-20% of active numbers may become inactive or invalid within a week (the specific proportion varies depending on industry, region, and marketing intensity). If the number pool is not rescreened for a month, the activity of the number pool may drop by more than 30%.

What factors affect the timeliness of Telegram screening results?

Changes in user behavior and activity

Users may deactivate Telegram due to moving, changing mobile phones, changing jobs, etc.; they may also change from “active” to “occasionally online”. Activity detection relies on the “recent online time” window (such as 24 hours, 7 days). The shorter the window, the shorter the data retention period. For example, a filtered number that is “active within 24 hours” may no longer be eligible the next day.

Platform policies and account bans

Telegram will ban accounts that send spam messages. If the “activated/valid” number you screen out belongs to an account that has been used for mass messaging but is now reported, it will most likely be blocked in a few days. The shelf life of this type of number is extremely short, and may even expire within a few hours of screening.

Addition and loss of number pool

It is common for carriers to recycle and reassign mobile phone numbers. For a number that you filter out as “Telegram enabled”, if the original owner cancels the account, the operator reassigns the number to a new user - the new user may not use Telegram at all. At this time, the “valid” records you obtained when screening numbers actually correspond to different people. In addition, a large number of new users registering for Telegram are also changing dynamically. If your number pool is not replenished with new number segments, the coverage will become increasingly narrow.

How to judge whether your filter number data needs to be re-screened?

There is no need to blindly rescreen every day. The following three judgment dimensions can be used as a reference for your decision-making.

Based on time window: Recommended rescreening frequency

Marketing scenario	Recommended rescreening frequency	Description
Regular large-scale mass sending (such as cold start)	Rescreen every 1-2 weeks	Ensure that most numbers are still open and valid, and reduce invalid sending
High-precision targeted marketing (such as matching gender and age group screening)	Re-screening every 3-5 days	Gender/age data changes slowly, but activity changes quickly; it is recommended to shorten the cycle when combining testing
Real-time event marketing (such as event notifications, limited-time promotions)	Consistent with or shorter than the active window	For example, if you use the “active within 24 hours” filter, it is best to re-screen every 24 hours to ensure accurate reach
Only check the activation status (not concerned about activity)	Re-screen every 1-2 months	The activation status is relatively stable, but blocked numbers still need to be checked regularly

The above frequencies are empirical suggestions. You can fine-tune them based on the actual open rate and reply rate after sending.

Based on performance indicators: decrease in open rate and reply rate

If after your marketing message is sent, the open rate or response rate is significantly lower than the historical average (for example, from 15% to 5%), it means that the proportion of active users in the current number pool has dropped significantly. Rescreening should be started immediately instead of continuing to use the old data.

Practical Tip: It is recommended to record the open rate and response rate after each marketing send. When the signal is lower than the threshold for two consecutive times, the signal is re-screened. Don’t wait until the data is completely invalid before taking action.

Best practices for Telegram screening: How to make a re-screening plan?

Combined with the functions of the KK-DATA platform, the following operation procedures are recommended:

1. Initial screening number: Generate the target country/region number segment through the “Global Number Generation” function, or import your own number CSV; set the detection type (such as “Telegram activation + gender + active in the last 7 days”) and submit the task.
2. Export useful numbers: After the task is completed, export the filtering results (CSV/TXT) in the console.
3. Scenario-specific use: For example, numbers that are “active in the last 24 hours + male” will be used for instant push, and numbers that are “activated but not active recently” will be used for long-term cultivation.
4. Scheduled rescreening: Resubmit the exported file to the screening task according to the above recommended frequency. Note: When the same batch of numbers is screened again, you can use KK-DATA’s data deduplication warehouse to automatically skip the numbers that have been detected before and the status has not changed, and only charge for new changes, saving the balance.
5. Add new number segments: Regularly use the “Global Number Generation” function to add numbers from new number segments or new regions to expand the number pool coverage.

Example of rescreening schedule:

Number batch	Initial number screening time	Rescreening strategy	Last rescreening result	Next rescreening time
US +1 Section 555	2025-03-01	Rescreened every Monday	2025-03-07	2025-03-14
Indonesia +62 Section 812	2025-03-05	Rescreening every two weeks	2025-03-12	2025-03-26
Global random + gender female	2025-03-08	Rescreening every 3 days (active + gender)	2025-03-10	2025-03-13

You can also view the historical screening results in the task record of the KK-DATA console, directly export the file and resubmit it, and cooperate with the deduplication warehouse to automatically identify changes.

Common misunderstandings and precautions

• **Misunderstanding 1: “Screening once and using it for a month” is feasible. **In fact, activity data may be less than 70% accurate after a week. Unless you only do very infrequent batches, you must rescreen regularly.
• **Myth 2: The shorter the rescreening frequency, the better. ** Daily re-screening will increase balance consumption, and excessively frequent screening may also trigger platform restrictions. It is recommended to choose a reasonable period based on marketing goals and data trends, rather than blindly seeking the shortest possible period.
• **Misunderstanding 3: Ignoring the impact of detection type on shelf life. ** If you screen “tg active + gender” at the same time, the gender data changes slowly but the activity data changes quickly, and the overall shelf life is determined by the shortest dimension. When combining screen numbers, the rescreening rhythm should be set according to the activity window.
• Pay attention to balance management: Re-screening will consume the balance. It is recommended to maintain sufficient USDT balance in the console to avoid interrupting tasks due to insufficient balance. Please see the official website billing page for recharge details.

FAQ

**Q: How long will it take for the Telegram screening results to become completely invalid? ** Answer: There is no fixed period. Usually the accuracy of activity data will decrease significantly after 1-2 weeks; the registration status has a longer shelf life (maybe 1-2 months), but it may still become invalid due to user logout. It is recommended to set the re-screening rhythm according to the marketing frequency.

**Q: I have a batch of old numbers, can I rescreen them directly without repeated charges? ** Answer: Yes. KK-DATA’s deduplication warehouse will automatically identify numbers that have been detected before, and only charge for numbers whose status changes. See the console task record for details.

**Q: Why does the “active” data in the filter results change the fastest? ** Answer: Because activity detection is based on the most recent online time (such as 24 hours/7 days window). Users’ online habits change frequently, and they may no longer meet the “24-hour active” condition after a few hours. It is recommended to use active windows that are tightly coupled with marketing activities.

**Q: Do I need to remember the number myself when re-screening, or can the platform automatically reuse it? ** Answer: You can view the previously filtered number list in the task record of the console, directly export the file and resubmit it; you can also use the “Global Number Generation” function to add new number segments, and then cooperate with the deduplication warehouse to perform incremental screening.

**Q: What should I do if my promotion’s open rate suddenly drops? ** Answer: First check whether the task is sent normally and whether it is blocked. After eliminating the sending problem, immediately re-screen the last number batch and add new number segments simultaneously. After the open rate recovers, the rescreening cycle can be shortened appropriately.
