Retargeting Active Telegram Users: Achieve Precision Re-engagement and Boost Repeat Purchases with KK-DATA

Silent users are not dead users. In overseas marketing, many teams spend significant costs acquiring Telegram numbers, only to let them sit idle after a single underperforming push. In reality, users who have previously interacted with your brand hold retargeting value far exceeding that of new customers. This article will explain the core logic of retargeting active users, and demonstrate how to use KK-DATA’s Telegram activity detection feature to efficiently and cost-effectively screen and re-engage silent users, increasing repeat purchase rates.

Why Are Silent Users Worth Marketing to Again?

“Silent users” typically refer to users already in your database who haven’t interacted with you recently. They may simply be temporarily inactive rather than completely lost. Re-engaging these users often yields a higher ROI than acquiring new customers with the same budget.

Definition and Classification of Silent Users

Based on Telegram activity data, common classifications are as follows:

Category	Recent Activity Window	Typical Behavioral Characteristics
Highly Active	Within 7 days	Daily login, instant replies
Moderately Active	Within 15 days	Occasional check-ins, irregular replies
Lightly Active	Within 30 days	Only checks key group messages
Silent Users	Over 30 days	No login or message behavior (number still valid)

Different classifications correspond to different re-engagement strategies: Silent users need strong incentives, moderately active users benefit from gentle interaction, and highly active users should be prioritized for maintenance.

Cost Comparison: Retargeting vs. New Customer Acquisition

Customer acquisition costs for new users are typically 5–10 times higher than retargeting (industry-acknowledged data). Reasons include:

• New customers require extensive testing of number validity and activity, which incurs screening costs.
• Silent users already have basic brand awareness, so outreach yields higher response rates.
• No need to rebuild trust (e.g., starting from scratch with introductions).

Therefore, leveraging your existing number pool for active user retargeting is an efficient way to reduce acquisition costs and increase lifetime value (LTV).

How to Use KK-DATA to Screen Telegram Active Users?

KK-DATA provides Telegram activity detection functionality, supporting custom activity windows (7/15/30 days). Combined with its “Generate → Screen → Export” closed loop, you can easily obtain a list of active numbers ready for retargeting.

Step 1: Prepare the Number List for Screening

You can prepare the number list in two ways:

• Import historical CSV: Upload number lists you’ve previously sent to or purchased from the console.
• Generate global numbers: Use KK-DATA to generate test pools by country/region or number prefix (generation is free; screening is charged per number). For existing numbers, prioritize importing your current data to avoid unnecessary generation.

Step 2: Set Up the Activity Detection Task

Log in to KK-DATA App Console and follow these steps:

1. Create a new task → Select the “Telegram” platform.
2. In detection type, choose “Activity Detection” and set the activity window (e.g., 30 days to check for online behavior in the last 30 days).
3. The system automatically calculates the estimated fee (see official billing page). Confirm and submit the task.
4. Once the task completes, you’ll receive a Telegram notification (requires prior binding), then export the results.

Step 3: Distinguish Silent from Active Users

Detection results indicate the activity status (active/inactive) for each number. Using these results, you can:

• Filter out silent users whose numbers are valid but have not been active in the past X days, then export them separately.
• Active users can be added to a ongoing maintenance pool, while silent users enter a re-engagement list.

This activity-based classification is the foundational data for active user retargeting.

Re-engagement Strategies Based on Activity Levels

After obtaining the segmented data, design differentiated strategies for each activity level to avoid user aversion from a one-size-fits-all approach.

Highly Active Users: Maintain, Don’t Disturb

Frequent active users usually have a favorable impression of your brand. Suggested strategies:

• Push new product previews or member-exclusive benefits to maintain interaction.
• Limit contact frequency to no more than 2 times per week.
• Provide internal discount codes or exclusive content to enhance loyalty.

Moderately Active Users: Gentle Re-engagement

These users open occasionally but haven’t formed a habit. Suggested strategies:

• Send 1–2 time-limited offers per week (e.g., “Today’s Deal” or “Discount Coupon”).
• Keep content concise and directly valuable (e.g., free resources, trial eligibility).
• Avoid consecutive sends; contact every other day and monitor response rates.

Silent Users: Revival-Style Retargeting

Silent users are a forgotten goldmine. Suggested strategies:

• Concentrate resources on high-appeal content: large coupons, free trials, referral rewards.
• Limit contact frequency: once every 3 days, for 2–3 consecutive attempts; pause if no response to protect number activity and account safety.
• Once a response is detected, immediately reclassify them into the active pool and shift to gentle maintenance.

Avoid Common Pitfalls: Retargeting Is Not “Spamming”

Many teams, upon obtaining active numbers, rush to “harvest” by sending high-frequency bulk messages, leading to user blocks or even complaints and account suspension. The core of active user retargeting is precision, not intensity.

Additionally, using KK-DATA’s TGID export function, you can add active users to a group for unified management, monitoring in-group interactions to avoid negative experiences from excessive private messaging.

Real-World Case: A Cross-Border E-Commerce Silent User Revival

Suppose a DTC seller runs a Telegram channel, accumulating 30,000 historical numbers (obtained through past campaigns but not contacted for 2 months). Using KK-DATA’s activity detection (30-day window), they screen out about 12,000 valid active numbers, with the remaining 18,000 being silent.

They split silent users into two groups for A/B testing:

• Group A: Received direct links to original-priced products. Response rate: 0.5%.
• Group B: Received “Limited 50% off coupon + exclusive benefit.” Response rate: 5.2%, conversion rate: 2.1%, ROI: 8x.

Thereafter, they periodically (monthly) re-check silent users, adding “revived” users back into the active pool, forming a continuous retargeting loop. The seller reported that revenue per user from retargeting was 3 times that of new customers.

(Note: This is a scenario illustration, not real customer data. Actual results vary by industry, content, and timing.)

How to Measure Retargeting Effectiveness?

Recommended core metrics:

• Click-through rate / Response rate: Measures content appeal. Adjust if below 1%.
• Conversion rate: Ratio from click to purchase or registration.
• Cost per revived user: Total screening cost / number of successfully revived users.
• Retention rate: Whether users remain active 7 or 30 days after revival. Use KK-DATA for periodic checks.

Attribution method: Embed parameterized short links in Telegram messages (e.g., utm_source=telegram&utm_campaign=retargeting) and track via Google Analytics or server logs.

Frequently Asked Questions

Q: How do I determine if a number is a “silent user”?

A: Silent users typically refer to those who have previously activated or interacted (e.g., were active in a group, clicked a link) but have not logged in or sent messages on Telegram in the last X days (e.g., 15 or 30 days). KK-DATA’s activity detection module allows you to filter by a custom-day window.

Q: Does screening active numbers with KK-DATA guarantee 100% successful re-contact?

A: No. Number screening only verifies the online activity status. Actual delivery success depends on whether the user has blocked you, network conditions, content quality, etc. However, using activity data can significantly improve delivery rates via SMS channels or bot messages.

Q: How many times do I need to pay during the retargeting process?

A: You only pay for the “number screening” stage (per check, e.g., Telegram activity detection). Sending messages afterward does not incur screening fees. Note: If you repeatedly screen the same numbers, use the deduplication repository to avoid duplicate charges.

Q: After reviving a silent user, how do I maintain their activity?

A: After revival, tag them as “recently active” and design a regular interaction plan (e.g., weekly content pushes, small benefits). Use KK-DATA’s periodic export mechanism to monitor activity changes and adjust strategy accordingly.

Q: Can I export the screening results for retargeting on other platforms (e.g., WhatsApp)?

A: KK-DATA supports multi-platform export (CSV/TXT), but registration status differs across platforms. The exported data is simply phone numbers. For WhatsApp retargeting, we recommend first using KK-DATA’s WhatsApp validity detection to confirm the number is active on WhatsApp before contacting.
