Telegram 3-Day Active Data ROI Calculation Guide: Cost, Cost per Reply, and Budget Optimization

When your overseas customer acquisition team plans to reach potential customers via Telegram private messages, a key decision is: Should you buy ordinary valid numbers, or active numbers that have been online within the last 3 days? The latter usually costs more per unit, but if you can accurately calculate the Telegram 3-day active data ROI, you’ll find that the premium for high activity likely results in a lower cost per reply. This article breaks down cost components, ROI formula, and optimization strategies to help you decide whether this investment is worthwhile based on data.

What Is Telegram 3-Day Active Data and Why Is It So Crucial?

“3-day active data” refers to numbers that have logged into Telegram within the last 3 days. This is fundamentally different from ordinary “valid numbers” (which only confirm registration but cannot determine recent activity status). 3-day active users mean:

• High reach rate: Private messages are more likely to be seen, rather than being buried in the inboxes of “offline users”
• High reply rate: Online users tend to respond immediately; reply rates are typically 2–5 times higher than ordinary numbers (varies by industry and copywriting)
• Low churn risk: Recent online activity indicates the account is still actively used, not a zombie account

Therefore, the “high activity premium” actually lowers overall acquisition cost by improving conversion efficiency. Understanding this is the prerequisite for calculating ROI.

How to Calculate the Acquisition Cost of 3-Day Active Data?

Obtaining 3-day active numbers through a screening platform (e.g., KK-DATA) mainly involves two cost components:

1. Screening fee: Charged per number checked. 3-day activity detection is a subtype of “activity detection” in Telegram screening, typically with a higher unit price than mere registration detection.
2. Number generation fee (optional): If you don’t have an existing number pool, you can first use the platform’s “global number generation” feature (free to generate) and then filter active numbers. Generation itself is free, but subsequent screening still deducts per number.

Billing model: No subscription plans; you need to pre-charge your balance using USDT (TRC20). After the task is completed, the fee is deducted from the balance. Before submitting a task, the console shows an estimated cost, allowing you to plan your budget precisely.

The exact unit price varies by detection type and platform. Please log into the console or check the official pricing page for real-time prices.

Breakdown of Screening Task Costs

The unit price for 3-day activity detection is typically 30%–50% higher than ordinary valid detection. For example:

• Ordinary valid detection: Only checks whether a number is registered on Telegram
• 3-day activity detection: Additionally determines “whether there has been online behavior in the last 3 days”, requiring more data queries, thus costing more

Suggestion: Before submitting a formal task, first check the current unit price on the KK-DATA console and test the actual deduction with a small batch of numbers.

Budget Example: Scenarios of 10,000 and 100,000 Numbers

Assume the unit price for 3-day activity detection is X yuan/number (based on the console). Then:

Number Quantity	Screening Cost (Estimated)	Generation Fee (if any)	Total Budget Reference
10,000	10,000 × X	0 (import own numbers)	About 10X yuan
100,000	100,000 × X	0 (generate then filter)	About 100X yuan

Example: If X = 0.02 yuan, cost for 10,000 numbers ≈ 200 yuan, for 100,000 ≈ 2000 yuan. Please refer to the console’s real-time numbers.

How to Calculate ROI for Telegram 3-Day Active Data?

General ROI formula:
ROI = (Revenue − Cost) / Cost × 100%

In customer acquisition scenarios, revenue is usually income from conversions, while costs include screening fees + subsequent outreach fees + labor costs. To make comparisons more intuitive, we introduce an intermediate metric: cost per reply.

Formula for Cost per Reply

Cost per Reply = Total Acquisition Cost / Number of Valid Replies

Total acquisition cost includes:

• Screening fee (for purchasing 3-day active numbers)
• Outreach tool fee (e.g., Telegram sender/bot, paid per message or per period)
• Labor cost (copywriting, sending, follow-up time)

Assume:

• Purchase 10,000 3-day active numbers, screening fee 200 yuan
• Use a sender for bulk private messages, tool fee 100 yuan
• Labor cost 50 yuan
• Total valid replies obtained: 300 (reply rate 3%)

Then total cost = 200 + 100 + 50 = 350 yuan
Cost per reply = 350 / 300 ≈ 1.17 yuan

Comparison scenario: If using ordinary valid numbers (unit price 0.013 yuan/number × 10,000 = 130 yuan, reply rate 1%), total cost = 130 + 100 + 50 = 280 yuan, replies only 100, cost per reply = 280 / 100 = 2.8 yuan.

Thus, high-activity data actually yields a lower cost per reply.

Is the High Activity Premium Worth It?

Compare the two sets of data:

Indicator	Ordinary Valid Numbers	3-Day Active Numbers
Screening unit price (assumed)	0.013 yuan/number	0.02 yuan/number
Screening cost (10,000 numbers)	130 yuan	200 yuan
Reply rate (actual)	1%	3%
Number of replies	100	300
Cost per reply	2.8 yuan	1.17 yuan

Conclusion: When the reply rate for 3-day active data is ≥2 times higher, even if the screening unit price is 50% higher, the cost per reply is still lower. ROI is naturally higher. We suggest you verify this with your own data.

3 Practical Budget Optimization Strategies

1. Run a small-scale test first, measure before buying
   Use 1,000–5,000 numbers for an A/B test comparing actual reply rates between 3-day active data and ordinary valid data. Decide on large-scale investment based on the results. This is the safest way to optimize budget.

   Small Batch Verification Suggestion

   It is recommended to run an A/B test with fewer than 5,000 numbers first, comparing reply rates of 3-day active vs. ordinary valid data, then decide whether to purchase at scale. The console supports submitting tasks in batches, making testing easy.

2. Use data deduplication to avoid duplicate charges
   KK-DATA provides a “data deduplication warehouse.” If the same number is checked in different tasks, the system intelligently deduplicates and does not charge repeatedly. Before submitting multiple batches, upload numbers to the deduplication library to save 10%–30% of screening costs.

3. Flexibly choose the activity window
   3-day activity is most effective but has the highest unit price. If your business does not require high timeliness (e.g., long-term content marketing), try 7-day or 15-day activity windows. They cost less while still providing better reply rates than ordinary numbers. When selecting the detection type in the console, compare unit prices for different windows.

3-Day Active Data vs. 7-Day Active Data: Cost and Effect Comparison

Dimension	3-Day Active Data	7-Day Active Data
Price	Higher (most stringent activity)	Medium (less stringent)
User activity	Very recent online users, highest reply willingness	Online within a week, still fairly active
Reach window	Suitable for promotions, flash sales	Suitable for regular content pushes, community operations
Volume size	Smaller after filtering	Larger (broader coverage)

Selection suggestions:

• If you need short-term high conversion (e.g., complete DM → purchase within 1 day), 3-day active is the best choice.
• For long-term brand exposure or content subscriptions, 7-day active offers better cost efficiency.

Notes When Using Screening Tools

1. Anti-scam reminder: Only contact customer service through official channels. KK-DATA’s official Telegram customer service is @kkdata_cc and the two-way bot @kkdata_robot. Any request to transfer money to unofficial accounts is fraudulent.
2. Balance management: Your account balance must be sufficient when submitting a task. If the balance runs out during execution, the platform will pause the task and notify you to recharge. It is recommended to keep at least 50 USDT in your account to avoid interruptions.
3. Export format selection: Results can be exported in CSV or TXT. CSV includes more fields (e.g., tgid, activity timestamp), useful for subsequent segmented sending. TXT is suitable for a pure number list. Choose based on your outreach tool’s requirements.

Frequently Asked Questions

Q: How much more expensive is Telegram 3-day active data compared to ordinary valid data?
A: The exact price varies by platform and detection type. Generally, 3-day activity detection costs 30%–50% more than mere registration detection. Please refer to the console’s real-time quote. The high activity premium mainly comes from stricter online behavior verification.

Q: How to estimate the total cost of a task?
A: Before submitting a task on the screening platform, the system displays an estimated cost based on the number of numbers and the selected detection type. For example, KK-DATA shows a clear deduction estimate on the task creation page, allowing you to adjust quantity or detection type accordingly.

Q: Can 3-day active data really improve reply rates?
A: Based on feedback from most overseas acquisition teams, the private message reply rate for 3-day active users is generally 2–5 times higher than for ordinary valid users, but this is influenced by copywriting, timing, and industry. It is recommended to test with a small batch in your own scenario.

Q: Will a task be interrupted if the balance is insufficient?
A: Sufficient balance is required when submitting a task. If the balance runs out during execution, the platform usually pauses the task and notifies you to recharge. It is recommended to maintain a minimum balance of about 50 USDT.

Q: What can the cost per reply be for 3-day active data?
A: Cost per reply = total spend ÷ number of replies. For example, if screening + sending costs total 100 yuan and you get 50 replies, the cost per reply is 2 yuan. High-activity data helps lower this number.
