Detailed Explanation of Telegram Screening Types: How to Choose tg Open, tg Active, tg Gender?

When you are doing Telegram group mass outreach to acquire customers, have you ever encountered this confusion: you bought millions of “open” numbers, but the private messages you sent got no replies, and you even received platform rate limits or warnings? The reason is simple—the screening type you chose is not deep enough. Telegram screening goes far beyond just “registration detection.” Different detection types (tg Open, tg Valid, tg Active, tg Gender) correspond to different data use cases. This article uses comparison tables + scenario guides to help you fully understand the differences and combinations of each type, and provides practical steps for using KK-DATA as well as a checklist of pitfalls to avoid.

What Are Telegram Screening Types?

Telegram screening types refer to the classification of bulk phone numbers based on different dimensions of detection. There are four main types:

• tg Open (Registration Detection): Only checks whether the number has registered a Telegram account.
• tg Valid (Availability Detection): Based on “Open,” further verifies if the number can currently be reached by active messages.
• tg Active (Activity Detection): Determines whether the account has been online or had interactions within a specified time window.
• tg Gender (Gender Recognition): Uses AI to analyze profile photos and output the user’s gender (Male/Female/Unknown).

Each detection type answers a different core question:

Detection Type	Core Question	Typical Use Case
tg Open	Does this number have a TG account?	Preliminary filtering of empty numbers
tg Valid	Can I send a private message to this number?	Mass DM, message delivery
tg Active	Has this user been online recently?	Immediate replies, community active users
tg Gender	Is this user male or female?	Gender-based segmented operations, personalized push

Why Distinguish Multiple Screening Types?

Because different acquisition scenarios have vastly different requirements for number quality:

• Group Invitation (Adding New Members via Groups): Only requires the number to have a registered TG account—tg Open is sufficient.
• Batch DM (Direct Messaging Marketing): Needs to ensure messages can be delivered and the recipient may view them—must use tg Valid (or even tg Active).
• Notification Push: For event reminders, product updates, requiring high timeliness—needs tg Active (short window).
• Personalized Operations: Push content by gender (beauty vs gaming)—requires tg Gender + tg Active combination.

If you only use tg Open for DM, you will likely encounter extremely low delivery rates because many numbers are abandoned, accounts are banned, or privacy settings block messages. Therefore, understanding and correctly selecting the screening type is the first step in overseas TG marketing.

tg Open vs. tg Valid: How Do Basic Detections Differ?

Many beginners think “Open = Valid,” but they are completely different. The comparison table below highlights the core differences.

Dimension	tg Open	tg Valid
Detection Content	Whether the number exists in the Telegram registration database	Whether the number can receive messages (two-way interaction)
Basis for Determination	Server returns yes/no for registration	Simulates message delivery status or specific interaction permission
Data Output	Registered / Not registered	Valid / Invalid (includes closed DMs, rate-limited accounts, etc.)
Typical Cost	Lower (see real-time prices in console)	Higher (see real-time prices in console)
Applicable Scenarios	Large-scale initial screening, removing empty numbers	Mass DMs, target pool of reachable users

What Is tg Open Detection?

tg Open is the most basic detection type. It only answers “Has this number registered on Telegram?” For scenarios where you only need to know the existence of a user (e.g., sending group invitation links—as long as the number has a TG account, they can receive the invitation), tg Open is sufficient. However, note: Open ≠ Reachable. Many numbers that have been registered but are long inactive (so-called “zombie accounts”) or those set to “only contacts can message” are open but cannot receive private messages.

What Is tg Valid Detection?

tg Valid goes a step further beyond registration detection by verifying whether the number can currently receive active messages. In other words, it excludes accounts that, although registered, are abandoned, have DMs disabled, or are subject to platform rate limits. For scenarios requiring actual user reach, such as DM marketing or customer activation, tg Valid is the minimum viable detection type.

tg Active Detection: How to Filter Users Active Recently?

tg Active further filters users who have been online or interacted recently. Even if a number is valid and open, if the user hasn’t logged in for six months, sending a message will likely get no response. Active detection helps you lock in users with high response potential from your target pool.

How Does the Activity Window Affect Data Quality?

KK-DATA allows you to customize the activity time window, with common options including 7 days, 15 days, 30 days, etc. (depending on options available in the console). The shorter the window, the “hotter” the data, but the smaller the coverage; the longer the window, the larger the coverage, but it includes more low-frequency users.

Activity Window	Data Timeliness	Typical Recommended Scenario
7 days	Very High	Instant marketing, flash events, limited-time offers
15 days	High	Daily DM, product recommendations
30 days	Medium	User retention pool, long-term reach

Recommended strategy: First, run core data with a 7-day activity window to ensure same-day reachability; then, supplement the remaining numbers with a 30-day window to expand the pool. If your goal is long-term community building, a combination of 30-day active + tg Valid is sufficient.

tg Gender Recognition: What Can Profile Photo Analysis Do for You?

tg Gender detection uses AI to analyze the user’s profile picture and output a gender label (Male/Female/Unknown). This feature is very useful for teams that need gender-based layered operations.

Use Case Examples:

• Beauty & Skincare E-commerce: Only filter “Female” users to push new product information.
• Games/Tools Apps: Focus on male users.
• Event Draws: Use separate channels for male and female to increase participation.

Accuracy Limitations: If the profile picture is not a real person (e.g., scenery, cartoon, celebrity photo), blurry, or the user has not set a profile picture, the result will be marked as “Unknown.” Therefore, gender detection accuracy cannot be 100%. It is recommended to use it as an auxiliary dimension rather than the sole filtering criterion.

How to Combine Screening Types Based on Operation Scenarios?

The checklist below helps you make quick decisions. Assume you have a list of tens of thousands of numbers. Following the priority of “coarse then fine,” it is recommended to follow: tg Open → tg Valid → tg Active/Gender.

Operation Scenario	Recommended Detection Combination	Reason
Group invitation link sending	tg Open	Having an account is enough to receive the invitation, lowest cost
Batch DM (without gender segmentation)	tg Valid + tg Active (7 days)	Ensure reachability + high response
Gender-based content push	tg Valid + tg Active (30 days) + tg Gender	Comprehensive quality + persona
Male/Female stratified lottery event	tg Active (7 days) + tg Gender	Timeliness + gender, fast execution
Broad user notification	tg Valid	Balances coverage and reachability

If you are unsure about the first step, simply choose tg Valid—it covers both registration and reachability, making it the most versatile detection type. Then, depending on budget and purpose, you can add activity or gender.

How to Use KK-DATA for Multi-Type Telegram Screening

Using the KK-DATA console as an example (also refer to the Documentation), here is the complete workflow:

1. Log in to the console: Visit https://app.kkdata.cc/ and authorize login via your Telegram account.
2. Create a screening task: Click “Create Task” on the homepage and select “Telegram Screening.”
3. Select detection types: In the “Detection Type” area, you can check multiple options (tg Open, tg Valid, tg Active, tg Gender). Note: For active detection, you need to specify the number of days (e.g., 7 days). Gender detection automatically uses profile photo analysis.
4. Upload numbers: Supports CSV and TXT formats. A single file can contain up to about 1 million numbers (see console limits for details).
5. View estimated cost: The task preview page shows the estimated total deduction for the selected combination of detection types. Different detection types have different unit prices, subject to real-time prices in the console.
6. Submit and pay: Confirm that your balance is sufficient, then click “Submit.” If your balance is insufficient, you need to top up USDT (TRC20) to your balance (minimum about 50 USDT). After top-up, your balance will be updated automatically.
7. Wait for notification: After the task is completed, you will receive a notification via Telegram (you need to bind your Telegram account in advance). You can also check the progress in the task history list.
8. Export results: After screening, download the results in CSV/TXT format. The result includes the original number, detection results for each type (e.g., Open=Yes/No, Valid=Yes/No, Active=Yes/No, Gender=Male/Female/Unknown), as well as tgid/wsid (if exported).

Common Misconceptions and Notes for Telegram Screening

Misconception 1: Only test Open without testing Valid

Correct approach: If you are using it for DM or mass messaging, at least do tg Valid detection. Open detection will miss many “zombie accounts” and accounts that have disabled DMs.

Misconception 2: Choosing the wrong activity window leads to data waste

Correct approach: Use 7 days for instant marketing and 30 days for long-term retention. Do not start with the widest window, otherwise the data will not be “hot” enough, and response rates will be low.

Misconception 3: Not using the deduplication repository leads to duplicate charges

Correct approach: Enable the “deduplication repository” in KK-DATA. The same number will only be detected once, and subsequent tasks will automatically skip it, saving your balance. See the Documentation.

Misconception 4: Trusting unofficial customer service

Correct approach: The official KK-DATA customer service only uses the contact information published on the official website (https://t.me/kkdata_robot and @kkdata_cc). Any “customer service” contacting you through other accounts is fake. Do not transfer money or provide account information.

Misconception 5: Ignoring the error rate of gender detection

Correct approach: Gender detection is based on AI recognition of profile photos and cannot be 100% accurate. It is recommended to use it only as an auxiliary filtering dimension and not rely solely on a single gender label for high-cost decisions.

Frequently Asked Questions

Q: Is there a big difference in unit price between tg Open and tg Valid detection? Why are prices different?

A: The specific unit prices are based on real-time display in the KK-DATA console. Generally, tg Valid detection requires higher interaction verification (simulating message delivery), so the cost is higher than simple registration queries. It is recommended to compare the estimated costs of different combinations on the task preview page before making a choice.

Q: I want to detect both activity and gender at the same time. Which one should I do first?

A: There is no fixed order. In KK-DATA, you can check multiple detection types for the same number in one go, and all detections will be completed in a single task (cost is combined). It is recommended to first select “tg Valid + tg Active (7 days) + Gender” because validity is the foundation, while activity and gender are additional dimensions.

Q: What is the basis for determining tg Active? Is there a big difference between 7-day and 30-day active results?

A: Activity determination is based on the Telegram account’s online or interaction behavior data within the specified time window (the specific algorithm is not publicly disclosed by the platform but is standard practice). 7-day active covers recent high-frequency users, while 30-day active includes weekly or monthly active users. The difference is significant: typically, the number of accounts active in 7 days is about 30%-50% of those active in 30 days, but the response rate is higher.

Q: I have many duplicate numbers. Will I be charged multiple times?

A: KK-DATA provides a data deduplication repository feature. When uploading numbers, you can choose to enable “deduplication,” and the system will automatically remove numbers already in the repository to avoid duplicate detection. It is recommended to confirm that deduplication is enabled before each task to save your balance.

Q: How accurate is gender detection? What if the user’s profile photo is a landscape or an animal?

A: Accuracy depends on the quality of the profile photo. Recognition accuracy is higher for real frontal face photos, while pure scenery, cartoons, group photos, etc., will output “Unknown.” Generally, team statistics show that gender recognition rate for global numbers is about 70%-80% (Male/Female), with the rest being Unknown. Do not rely solely on gender results for sole decision-making.
