What is Telegram Active Data Retargeting?

Retargeting in the context of Telegram refers to the strategy of reaching out to users who have already registered and used Telegram a second or multiple times based on their recent active behavior. Unlike one-time new customer acquisition, the core of retargeting data is not “account opened” but “still in use”.

Retargeting vs. New Customer Acquisition: What’s the Core Difference?

Comparison Dimension	New Customer Acquisition	Retargeting (Silent Wake-Up)
Data Threshold	Only requires “opened” or “valid”	At least requires “active” level
Purpose of Reach	First contact	Wake up dormant users, promote repeat purchases
Conversion Rate	Low (typically 少于5%)	Higher (active user reply rate can reach 10–30%)
Cost	Low per-check cost, but many ineffective reaches	Slightly higher check cost, but less waste
Account Ban Risk	Medium	Low (users are active, low complaint rate)

Why Is Activeness More Important Than Simply “Opened”?

KK-DATA’s number screening capabilities are divided into three levels:

• Opened (Registration Check) : Only confirms the number is registered on Telegram, but doesn’t indicate whether the user is still using it. Many numbers are abandoned or have become zombie accounts.
• Valid : Account status is normal, but cannot determine recent login time.
• Active : Precisely filtered by last active time (e.g., logged in within 7 days, 15 days, or 30 days). Retargeting at least requires “valid” or “active” data, otherwise your messages may go unanswered or even be reported due to prolonged inactivity.

Silent User Wake-Up: Which Data Fields Are Most Worth Attention?

To achieve efficient silent wake-ups, you need to focus on the following three key data fields:

1. Last Active Period : Directly determines whether the user is “reachable.” For example, a user active in the last 7 days is much more likely to open a message than one active 30 days ago.
2. Registration Time : Combined with the active window, helps determine the user’s lifecycle. If a user registered long ago but hasn’t been active recently, they may have abandoned the account; newly registered and active users are golden.
3. Gender Identification (Avatar Recognition) : Determines gender from the avatar, which can be used for differentiated messaging or product recommendations to increase reply rates. For example, beauty brands send promotions to female users, while electronics brands target male users.

Practical Advice: First batch-screen your number pool for “active” status, then segment them into different audience groups based on gender fields, and import into bulk messaging tools for layered wake-ups. KK-DATA’s export feature supports CSV/TXT, which can be directly connected to CRM or Telegram bulk messaging systems.

How to Build Re-Engagement Audience Segments Using Active Filtering Criteria?

Here are the standard operating steps:

1. Prepare the Number Pool: Can be obtained from historical orders, old customer lists, public channel scraping, or number generation tools. Note: Generation is free, screening is charged per check.
2. Set the Active Window: In the KK-DATA console, create a new task, select “Telegram Active Detection,” and specify the window (7 days, 15 days, 30 days). The system will batch-screen and return each number’s tgid, active status, and last online time.
3. Filter and Export: Keep only numbers with active status “Yes,” and optionally check additional fields like gender and tgid for export.
4. Deduplication: Use the platform’s built-in data deduplication warehouse to automatically deduplicate across tasks and avoid re-checking the same number, saving budget.
5. Import into Bulk Messaging Tools: Import the exported CSV file into your commonly used Telegram bulk messaging tool (e.g., TG Member, Telegram Bot, etc.) to start re-engagement.

Setting the Active Window: What Scenarios Are Best for 7-Day, 15-Day, and 30-Day Windows?

• 7-Day Window: Suitable for high-frequency promotions, daily flash sales, and time-limited events. Users were online in the last 7 days, so reply speed is fast and conversion rates are high.
• 15-Day Window: Suitable for weekly content pushes, such as industry news, product updates, and community invitations. Covers more users, and most can still engage.
• 30-Day Window: Suitable for brand long-cycle wake-ups, holiday marketing, and big sale preheating. The window is broader, but reply rates drop; suitable for low-cost coverage.

How Does Gender Identification Help in Retargeting?

Suppose you have 100,000 numbers; through gender identification, you identify 60,000 female and 40,000 male users. You can push different messages:

• Female users: Emphasize beauty and clothing discounts, with a “recommended by friends” tone.
• Male users: Focus on tech performance and cost-effectiveness, using “limited-time flash sale” language.

Real data shows differentiated content can increase reply rates by 15–40%. KK-DATA’s gender identification is based on AI avatar analysis with an accuracy of about 70%, suitable as a reference for audience segmentation.

Common Pitfalls of Re-Engagement and How to Avoid Them

In overseas retargeting, be especially careful about these three pitfalls:

1. Over-reach leading to reports: If the same user receives more than 5 bulk messages in a week, they are very likely to report you, leading to account bans. It’s recommended to limit frequency to 1–2 times per week, and always check the last active time before each send.
2. No deduplication in the number pool wastes budget: Using historical lists directly for screening may include many already-checked numbers. Each screening will be charged repeatedly. Use KK-DATA’s deduplication warehouse to eliminate 30–50% of invalid checks.
3. Directly using “opened” number pools for bulk messaging: Some teams only check “opened” to save money, but the “opened” status may contain many long-term inactive zombie accounts. After bulk sending, delivery rates are low, and it’s easy to trigger Telegram’s spam mechanism.

How to Measure the Effectiveness of Retargeting After Keyword Screening?

For Telegram active data retargeting, it is recommended to track the following metrics:

• Message Delivery Rate: Number of messages delivered (from the bulk messaging tool) / total sent. If below 60%, the number pool quality is poor and should be re-scanned with active detection.
• Reply Rate: Number of users who replied / number of delivered messages. For normal active users, reply rates range from 10–20%; with promotional stimulation, it can reach 30%+.
• Group Join Conversion Rate: If the goal is to invite to groups, measure the percentage of users who clicked the invitation link.
• Single Wake-Up Cost: Total cost (screening fees + bulk tool fees) / number of effective interactions or orders. Compared to new customer acquisition costs, this can be 50–70% lower.

KK-DATA’s exported data includes tgid, which you can use to link to your own backend system, track individual user behavior, and calculate ROI.

Frequently Asked Questions

Q: What is Telegram active data retargeting?
A: It refers to the strategy of filtering out highly active numbers based on whether users were online within a certain time period (e.g., last 7 days, 15 days, or 30 days), and then reaching out a second or multiple times. Unlike one-time acquisition, retargeting focuses on silent wake-up and mining value from existing users.

Q: Is it enough to only check the “opened” status for retargeting?
A: No. “Opened” only indicates the number is registered on Telegram but cannot determine if the user still uses the account. Retargeting at least requires “valid” or “active” level data; it is recommended to use an active window to improve delivery quality.

Q: Which is better for the active window: 7 days or 30 days?
A: Depends on the scenario. For high-frequency promotions (e.g., daily flash sales), choose users active within 7 days; for brand content wake-ups or holiday marketing, the 15–30 day window is suitable to cover more potentially active users, but reply rates may be lower.

Q: When re-engaging a large volume of numbers, how to avoid duplicate checks?
A: It is recommended to use the data deduplication warehouse feature (e.g., cross-task deduplication provided by KK-DATA) to avoid the same number being charged multiple times across different batches and to reduce repeated disturbance to users.

Q: Can the active data screened by KK-DATA be used directly in bulk messaging tools?
A: Yes. It supports multiple export formats (CSV, TXT) and can be directly imported into mainstream Telegram bulk messaging tools or CRM systems. It is recommended to do another deduplication check before exporting.
