Base material selection and acceptance guide: 5 key criteria for studios to deliver high-quality customer acquisition data

For overseas customer acquisition studios, the quality of the delivered “base material” - that is, the filtered list of valid numbers - directly determines the customer’s marketing cost and final conversion rate. What is base material screening? Simply put, it is to screen out high-potential users that meet marketing goals from a huge pool of original numbers through multi-dimensional detection (platform activation, activity, gender, deduplication, etc.). As a data service provider, if the screening standards for base materials are not unified and the process is not standardized, customers may receive a large number of invalid numbers, resulting in a low sending success rate and a high risk of account suspension, which will further affect the reputation of cooperation and repurchase.

From the perspective of studio delivery and acceptance, this article explains in detail the five core dimensions that must be controlled in base material selection, and gives specific practical suggestions to help studios establish a standardized delivery process.

What is base material screening? Why do studios need standardized acceptance?

The concept of base selection comes from “hot pot base” - the quality of the raw materials determines the final taste. When acquiring customers overseas, the base material is the list of numbers you will reach. Unfiltered raw numbers tend to contain a lot of:

• Numbers not registered on the target platform
• “Zombie accounts” that have been inactive for a long time
• Gender, age and other portraits are unclear, resulting in waste of targeted marketing
• Duplicate numbers and sending them multiple times can easily cause resentment among users and even trigger platform risk control.

As a professional data screening service provider, the quality of the base materials delivered by the studio directly affects the actual marketing effect of the customer. Standardized acceptance means:

• Clarify each delivery field (such as whether it is activated, active time, gender, age range)
• Develop quantifiable qualification standards (such as activity thresholds, deduplication rate requirements)
• Use reliable screening tools and deduplication mechanisms to reduce human errors

Only by standardizing acceptance can the studio establish a “professional and trustworthy” brand image in front of customers and increase repurchase rates and referrals.

Comparison before and after base screening: unscreened numbers vs. professional base screening

In order to visually demonstrate the value of base material screening, we use a table to compare the quality of the numbers in the two situations:

Comparison dimensions	Unfiltered numbers	Numbers filtered by professional background materials
Platform registration rate	About 30%~60% (a large number of numbers are not registered on the target platform)	Usually ≥90% (only numbers that have been activated are retained)
Activity	Most numbers have not logged in for a long time and have no response to messages/emails	Can remain active within a specified window (such as 7 days, 30 days)
User portrait clarity	Gender and age fields are unknown, and fine targeting cannot be done	Gender (such as male/female) and age range can be obtained, and targeted delivery is supported
Data duplication rate	May be as high as 10%~20% (the same number appears in different batches)	After processing through the deduplication warehouse, the duplication rate can be controlled below 1%
Contact Cost and Risk	Low reach rate (less than 30%), easy to be blocked for sending invalid numbers	Increase the reach rate to more than 80%, reducing the risk of account ban

Note: The above comparison is based on general industry experience. Actual results vary depending on the platform, region, and raw data quality. The studio should explain the expected improvement before and after screening to the client at the time of delivery and rely on actual data to prove it.

Four core dimensions that must be accepted when screening the base materials delivered by the studio

Before delivering the base material, the working group needs to check the following four key dimensions one by one to ensure that each number has been fully tested. These are explained one by one below.

How to confirm whether the number is activated?

The first step in screening is to confirm whether the number has been registered and activated on the target platform (such as Telegram, WhatsApp, Line, Zalo, etc.). Sending messages to an unactivated number is a waste of effort and may also result in the platform account being flagged.

Acceptance Criteria:

• There should be a clear “activation status” field in the exported data (such as “True/False” or “1/0”)
• For multi-platform requirements, the activation status of each platform should be listed separately.
• KK-DATA supports activation detection of Telegram, WhatsApp, Line, Zalo, iMessage, RCS, Viber and other platforms, and the export fields are clearly marked

Practical suggestions: The studio can randomly check 5% to 10% of the numbers before delivery, and manually search and verify on the target platform to ensure accurate test results.

How to determine the activity of a number and user portrait?

It’s not enough to activate it. What customers need are active users. Activity detection can specify a time window (such as “online in the past 7 days”) to accurately filter out users who have interacted recently. At the same time, user portraits (gender, age) can help customers do targeted marketing.

Acceptance Criteria:

• The base material should contain an “Activity” field, indicating the last active time or activity level
• If there is gender recognition, you need to export gender (such as Male/Female) and age fields (such as age range or specific value)
• KK-DATA’s Telegram filter supports activity detection (window can be specified), gender identification (including age field, can be used to filter people around 30 years old, etc.)

Note: The accuracy of gender and age is reference level (inferred based on platform public information), not ID card level, and studios should explain this to customers.

How to verify the accuracy of gender targeting?

If the client needs to target male or female users, the base material must include a reliable gender field. Currently, gender data from platforms such as Telegram and Line can be used with a certain degree of accuracy.

Acceptance method:

• After exporting the gender field, randomly select samples to assist in judgment through other channels (such as user public information, community nicknames)
• Compare the consistency of gender data on different platforms (for example, detect Telegram and Line at the same time to see if they are consistent)
• Both Telegram and Line screens of KK-DATA support gender recognition, and detection options can be set in the console.

Delivery requirements: Ensure that the gender field is non-empty in more than 90% of cases (for activated and active numbers).

How to verify the completion of deduplication?

Duplicate numbers are a big no-no in base material screening. If a customer receives the same number multiple times, it will not only waste money, but may also lead to user complaints or account suspension due to repeated contacts.

Acceptance Criteria:

• The delivered list should be clearly marked “after deduplication” and the duplication rate should be less than 1% (ideal)
• Studios should use deduplication tools (such as KK-DATA’s deduplication warehouse) to merge and deduplicate multiple batches of tasks.

Practical steps:

1. Import all numbers to be delivered into the deduplication warehouse (supports cross-task deduplication)
2. The system automatically eliminates existing numbers and only retains newly added valid numbers.
3. Check again for duplicates before exporting

Why is data deduplication a required course for base material screening?

For studios, deduplication is not only a quality assurance for customers, but also a means of saving costs. Because screening numbers are deducted on a per-item basis, repeated testing of the same number is a waste of balance.

How does deduplication warehouse work?

KK-DATA provides a cross-task number deduplication warehouse. The process is as follows:

• Before each number screening task is submitted, the system will check whether the number has been detected.
• If the number is already in the warehouse, skip it (no repeated deduction)
• If the number is new, it will be detected normally and stored in the database.
• The deduplication warehouse is independent of the screening task and can be stored for a long time.

Value to studios: When you obtain numbers from different channels multiple times and hand them over to customers, you only need to purchase the screening number once, and only the new number will be charged for subsequent superimposed numbers based on deduplication logic, significantly reducing costs.

Acceptance criteria for deduplication: How to ensure that the numbers received by customers are not duplicated?

The studio should perform the following checks before delivery:

1. Local deduplication: Use Excel or script to deduplicate the exported CSV by the “Number” column to ensure that there are no duplicate rows.
2. Cross-platform deduplication: If the customer wants Telegram and WhatsApp data at the same time, please note that the same number may be activated on both platforms at the same time. Do you need the customer to specify the deduplication requirements (for example, only keep records of one platform).
3. Use KK-DATA’s deduplication export: When exporting in the console, select “Effective numbers after deduplication” to get a duplicate-free list.

Common misunderstandings in base material selection and pitfall avoidance guide

It is easy for studios to make pitfalls in practical operations. Common mistakes and suggestions are listed below.

Misunderstanding	Correct approach
Only look at activation, not activity	Add activity detection to filter out “dead accounts” that have never been online after registration.
Ignore the gender/age field, regardless of customer targeting needs	Know in advance whether the customer wants targeted marketing, if necessary, you must add gender/age detection.
Directly deliver multiple batches of mixed results without deduplication	Use a deduplication warehouse or script to ensure that there is no duplication in the delivered data.
Rely on single platform data	If possible, use multiple platforms such as Telegram and Line to detect and cross-validate user portraits.
Exaggerate the detection accuracy rate	Honestly explain to customers that the gender/age data is a reference level to avoid disputes caused by accuracy issues.

How to choose a suitable base material screening tool?

When choosing a screening tool, studios should focus on evaluating the following factors:

• Platform Coverage: Whether it supports mainstream platforms such as Telegram, WhatsApp, Line, Zalo, iMessage, and RCS
• Detection dimensions: In addition to activation, whether activity, gender, age, uid/tgid, etc. can be detected
• Billing model: Billing by item (no subscription) is more flexible and suitable for tasks of different sizes in the studio
• Batch processing capability: Can a single task support more than 1 million items?
• Data deduplication function: Is there a built-in deduplication warehouse, and is cross-task deduplication free?
• Export format: supports CSV, TXT and other common formats, fields can be customized
• Customer Support: Is there a quick response channel (such as Telegram two-way customer service)

As a one-stop screening platform, KK-DATA has mature capabilities in all the above aspects: it supports 240+ country/region code generation, multi-platform screening (Telegram/WhatsApp/Line/Zalo/iMessage, etc.), per-item billing without subscription, built-in deduplication warehouse, and provides real-time support for Telegram robots. Studios can try it out based on their own needs.

FAQ

**Q: What is the difference between base material screening and ordinary number verification? **

Answer: Ordinary number verification usually only detects whether the number is activated (registered). Base material screening is a more complete process service. It not only verifies activation, but also detects user profiles such as activity, gender/age, etc., and performs data deduplication to ensure that the delivered number list is of high quality and can be directly used for marketing.

**Q: How does the studio ensure that there are no duplications in the base materials delivered? **

Answer: It is recommended to use the deduplication warehouse function of the number screening platform (such as KK-DATA’s deduplication warehouse) to uniformly import all the numbers to be delivered to remove duplications, and the system will automatically filter the existing numbers. You can also use Excel or scripts to check for duplicate values ​​after exporting.

**Q: Is Telegram’s gender and age data accurate? **

Answer: The accuracy is reference level. It is inferred based on Telegram’s public information (such as account display information) and cannot reach ID card level. But it is enough for targeted marketing (such as screening men aged 20 to 35). It is recommended to explain the data source and accuracy range to the customer.

**Q: Is there a limit to the number of screenings per session? **

Answer: Taking KK-DATA as an example, a single task can handle up to about 1 million numbers. If larger batches are required, they can be submitted in batches. The deduplication warehouse can be accumulated across tasks to avoid repeated detection.

**Q: How is the screening fee calculated? Can the unused balance be refunded? **

Answer: Screen numbers are deducted on a per-item basis. Different platforms and detection types have different unit prices. For specific prices, please see the real-time price on the console. The balance is recharged in USDT (TRC20), with a minimum of about 50 USDT. There is no refund after recharging, but the balance is valid for a long time and can be used for subsequent tasks.
