TG filtering - why you must filter Telegram numbers before sending cold private messages

When acquiring customers via cold private messages on Telegram, many teams directly import batch numbers into the mass messaging tool, only to face the triple blow of account closure, extremely low response rate, and waste of resources. A fact that has been repeatedly verified is: The success rate of cold private messages without TG filtering is less than 10% of blind investment. This article will systematically explain why telegram number filtering (tg filtering) is the starting point for all cold private messages to acquire customers, and how to use KK-DATA to efficiently complete this key step.

Why is it necessary to do TG filtering before cold private messages?

The pain points of high account blocking and low conversion of blind mass messaging

Telegram’s banning mechanism for unverified numbers is very strict. When you send a private message to an unregistered Telegram number, the system will immediately determine that the sending behavior is abnormal; multiple consecutive invalid sendings will trigger risk control, causing your sending account to be blocked. What’s worse is that even if the number is registered with Telegram, if the other party has been inactive for a long time (for example, not online for several months), the private message may be defaulted as harassment information by the system after being delivered, which will also reduce the account weight.

From a cost perspective: Obtaining or generating a number list, purchasing a sending account, and spending time configuring scripts—these investments are often lost after blind mass sending. According to industry feedback, the TG activation rate of random numbers is usually only about 30%, and the activity rate is even lower than 10%. This means that the sending cost you spend 100 yuan to recharge is less than 10 yuan to actually reach effective users.

How TG filtering directly reduces risk and improves ROI

The core logic of tg filtering is: Detect first, then send. Use technical means to determine whether each number is registered on Telegram, whether it has been online recently, and possible gender/age attributes. After filtering, you only keep those numbers that are open and active, and you can even further filter based on the target group (such as 30-year-old men). Doing so brings at least three benefits:

• Reduce the risk of account ban: Avoid sending messages to invalid numbers and reduce the number of risk control triggers.
• Increase reply rate: Only send to active users, the reply rate can be increased by 3-5 times.
• Save Money: Don’t waste calls on invalid numbers, and each private message will be more valuable.

**Summary in one sentence: tg filtering is not a cost, but an investment - it determines the upper limit of ROI for your cold private messages. **

Which dimensions should be filtered by TG filtering?

Not all tg filters are equal. You need to select the specific detection type on platforms such as KK-DATA to get usable data.

tg activation detection - determine whether the number is registered with Telegram

The most basic filtering dimension. Unregistered numbers are discarded directly to avoid invalid sending. This step can filter out about 60% to 70% of random numbers (depending on the source of the numbers).

tg activity detection - looking for real users who have been online recently

Telegram user activity is usually divided into several windows: 7 days, 14 days, 30 days, and 90 days. For cold private messages, it is recommended to choose a 7-day or 14-day active window because users who have been active recently are more likely to open and reply to the message. KK-DATA supports customizing the active window, which you can adjust according to product type.

telegram gender and age data - precise targeting of people

This is an advanced filter. The telegram gender detection provided by KK-DATA can return the user’s gender (male/female) and approximate age fields. **Note: Age is a derivation result, not the accuracy of the ID card. ** It can be used to divide people around 30 years old, around 20 years old, etc. For example, a men’s skin care product can target “male + about 30 years old” numbers to improve conversion efficiency.

Usage example:

• Cross-border e-commerce: Promote outdoor equipment to men aged 30 to 40 years old.
• Community attraction: a beauty group for women aged 18 to 25.

TG filtering vs direct bulk sending: 5 key comparisons

Comparison dimensions	Direct mass sending (no filtering)	TG filtering and then mass sending
Account ban rate	High (30%~60% of accounts are banned within a week)	Low (can be controlled within 5%)
Effective contacts per thousand	About 100~300 people	About 600~800 people
Average response rate	0.5%~2%	5%~15%
Data reusability	Numbers can no longer be used after being marked	Filtering results can be exported and support retention and reuse
Account Security	Sending an account can easily trigger risk control	The risk is greatly reduced and the account life is longer

Obviously, tg filtering is not optional, but required. Especially when you plan to acquire Telegram customers in the long term, filtered data can continue to create value for you.

How to do TG filtering (take KK-DATA as an example)

The entire process requires only three steps and does not require any technical foundation.

Step 1: Prepare numbers to be screened

You can get the number in two ways:

1. Global number generation: Select the country (240+ countries/regions), number segment, and quantity in the KK-DATA console to generate unlimited numbers for free.
2. Import your own CSV: If you already have a list of target numbers, upload the CSV directly.

Step 2: Select the Telegram filter type and submit the task

In the “Screen Number Task” of the console, select “Telegram Screen Number” and check the required detection type:

• tg activation (required)
• tg active (7 days or 30 days recommended)
• telegram gender (optional, more contacts required)

You can submit up to about 1 million numbers at a time. Before submission, the system will display the estimated fee and the fee will be billed on a per-item basis. For details, see the real-time price on the console.

Step 3: Export the results and use them for cold private messages

After the task is completed, you will receive a Telegram notification (requires binding in advance). Results support CSV and TXT format export, including:

• Activated/Not activated
• Active/inactive (including last online time)
• Gender and age fields
• tgid (Telegram unique ID, can be used for advanced push)

After exporting, you can directly use these numbers to send cold private messages. KK-DATA also provides a data deduplication warehouse function to avoid repeated detection of the same number and save costs.

Common misunderstandings and precautions for TG filtering

• **Misunderstanding 1: The more filtering dimensions, the better. ** In fact, the two dimensions of activation + activation can already meet 80% of scenarios. Excessive filtering will significantly reduce the quantity, resulting in insufficient subsequent sending. Recommended to balance based on actual budget and conversion goals.
• **Myth 2: Gender and age identification are accurate. ** As mentioned before, age is a derived value and cannot be used in scenarios that require precise verification (such as ID card review).
• **Myth 3: After filtering, you can send unlimited messages. ** Filtering only reduces risk and does not allow you to ignore platform rules. Even if all numbers are open and active, you may still be blocked if you send a large number of messages with the same content in a short period of time.

How to evaluate the effect of TG filtering?

Quantitative metrics are key to measuring the value of filtering. It is recommended to record the following data:

• Original number → Open number → Active number → Number after gender filtering: The retention ratio of each layer of filtering.
• Task time consuming: During non-peak periods, the tg filtering task of 1 million numbers is usually completed within 30 minutes.
• Input-output ratio: Recharge amount ÷ Number of effective replies. For example, if you recharge 100 USDT, send after filtering and get 30 valid replies, then the single customer acquisition cost will be about 3.3 USDT.

Through long-term accumulation, you can find the filter combination that best suits your products.

Which scenarios are most suitable for TG filtering?

• Cross-border e-commerce independent station reminder: Based on the number list of potential customers, filter out Telegram active users and send preferential information.
• Community Recruitment: Screen active users in specific countries/regions and invite them to join Telegram groups.
• Agency Operation Studio: To acquire Telegram customers for multiple customers, an efficient screening system is required, and the pay-as-you-go billing model can control costs.
• Cold start of overseas apps: Screen 30-day active users in the target market and accurately push download links.

Whether you are an individual creator or a team operator, tg filter can help you spend your money wisely.

FAQ

**Q: What is TG filtering? ** Answer: TG filtering is Telegram number detection, which uses technical means to determine whether the target number is registered with Telegram, whether it has been active recently, and what gender/age attributes it may carry. The filtered numbers are more accurate and suitable for active customer acquisition scenarios such as cold private messages.

**Q: What is the difference between TG filtering and direct group sending? ** Answer: Direct mass sending without verifying the number may lead to a large number of invalid sending and high number blocking rate. TG filtering first removes unregistered and inactive numbers, and only retains real users who are likely to reply, thereby reducing risks and improving conversion efficiency.

**Q: Do I need a subscription package to do TG filtering on KK-DATA? ** Answer: No need. KK-DATA adopts the “recharge balance + deduction by item” model, with no monthly/annual fees. You can see the estimated deduction before each task is submitted, and you will pay according to the amount you use.

**Q: Can the filtered data be reused? ** Answer: Yes. KK-DATA provides a data deduplication warehouse function to avoid repeated detection of the same number. Filtering results can be exported via CSV/TXT for subsequent private messages or retention management.

**Q: Can TG filtering detect accurate age? ** Answer: No. The age field comes from the derivation result of telegram gender detection and can be used to divide the general population (such as about 30 years old), rather than the precise ID-level value. When using it, it should be interpreted reasonably based on the business scenario.
