Screen for Open First or Active First? The Correct Filtering Sequence for the TG Marketing Funnel

In the actual execution of Telegram marketing, many operators fall into a classic pitfall: directly screening for active users right away, or only screening for open and ignoring what comes next. The result is often that a lot of budget is spent, but the acceptance rate for adding friends is low, and the probability of private messages being replied to is even lower.

The root of the problem is not the detection tool itself, but the lack of a proper filtering sequence. Whether to screen for open first or active first is essentially not a single-choice question, but a decision-making process based on marketing goals. Starting from the TG marketing funnel, this article helps you clarify the progressive relationship of “open detection → valid detection → active detection”, and provides a visual cost analysis and operational guide.

Understand the Key Concepts: TG Open, TG Valid, TG Active

Before discussing the sequence, you need to clearly understand what these three concepts represent. Many confusions come from misaligned understanding of the terms.

Open Detection vs. Valid Detection — First Distinguish “Existence” from “Usability”

• TG Open Detection: Verifies whether a phone number is registered on Telegram. It only answers one question: “Is this number a TG user?” This is the most basic and lowest-cost layer of detection.
• TG Valid Detection: On the basis of open, it further verifies whether the number can be searched and can receive messages. Even if a number is registered on TG, if the owner has set it to “Disable search by number” or the account is deactivated, it is invalid for you.

Example: You have 100,000 numbers. Open detection tells you that 60,000 have TG accounts, but valid detection tells you that maybe only 40,000 can actually be reached. If you directly use the open list for mass messaging, 20,000 messages will be sent in vain.

Active Detection — Your Precision Audience Filter

Active detection goes one step further on the basis of “valid”. It is based on the user’s last online time (e.g., online within the last 7 days / 15 days / 30 days), filtering out users who have been active recently.

• High activity window (7 days): Suitable for time-limited events, urgent notifications, and time-sensitive marketing.
• Wide window (30 days): Covers more people, suitable for brand building and long-term outreach plans.

If your goal is for messages to be seen and replied to, active detection is an essential step. Even for valid numbers that are not active, sending messages will most likely go unnoticed.

Relationship Diagram — Layered Filtering in the Funnel Model

All numbers → Open Detection → Valid Detection → Active Detection
Precision:   Low                Medium            High
Volume:      Large              Medium            Small
Cost:        Low                Medium            High

Each layer of filtering eliminates some numbers, leaving behind your “golden pool”. The further down the funnel, the higher the data value, but also the higher the single detection cost. Therefore, the core of arranging the filtering sequence properly is to spend money where it matters most.

Filtering Sequence Decision Tree: Your Goal Determines the First Step

Whether to screen for open first or active first depends on your subsequent marketing actions. The decision table below helps you quickly locate your scenario.

Marketing Scenario	Primary Detection	Secondary Detection	Optional Detection	Reason
Community recruitment / Bulk add friends	Open Detection	Valid Detection	Skip Active	Goal is mass user contact info; open detection is lowest cost and highest efficiency
Private message promotion / Mass messaging	Open Detection	Valid Detection	Active Detection	First ensure numbers are usable, then filter recently online users to improve reply rate
Precision lead mining / High ROI conversion	Valid Detection	Active Detection	Can skip Open	Limited budget; directly find recently active seed users in a high-value pool
Brand exposure / Build community atmosphere	Open Detection	—	—	Only need people to join the group; no interaction ability required; open is sufficient

Scenario 1: Community Recruitment / Mass Add Friends → Prioritize Open

If your goal is “get more people into the group”, then open detection is the first threshold. Only numbers that have opened TG can potentially be added by you. At this stage, you don’t need to know if they are online or how often they use it — it’s enough that they “exist”.

Recommended Flow:

1. Build the candidate pool (generate or import) → 2. Submit open detection → 3. Export open list → 4. Use directly for group invitations or friend additions.

Scenario 2: Private Message Promotion / Mass Messaging → Valid Detection First, Active Detection Follows

If you need to ensure message delivery and interaction probability, then Open → Valid → Active is the safest funnel.

• First layer (Open): Eliminate numbers without TG accounts, saving about 30%-50% of basic detection costs.
• Second layer (Valid): Ensure numbers can be searched/receive messages, avoiding invalid sends.
• Third layer (Active): Lock on recently online users, significantly increasing open and reply rates.

Recommended Flow: Open detection → Select “open” list from results → Submit valid detection → Select “valid” list → Submit active detection → Export active pool.

Scenario 3: Precision Customer Mining / High Intent Conversion → Screen Active on Valid Basis Directly

When budget is limited, you can skip open detection and directly screen for active users from a set of known valid (or high-value) numbers. For example, if you bought an industry database with numbers already preliminarily verified, the next step is to find those “recently online”.

Recommended Flow: Prepare a list of valid numbers (or directly select from the results warehouse of previous tasks) → Submit active detection → Export active pool.

Cost Analysis of Filtering by Sequence: When Can You Skip a Step?

Many operators worry that running all three steps will be too expensive, but actual calculations often show that skipping some steps can actually cost more.

Assume you have 100,000 numbers, and detection unit prices vary as displayed in the console (example numbers for comprehension; actual prices subject to real-time console):

• Assume Open Detection: 0.003 USDT/unit
• Assume Valid Detection: 0.005 USDT/unit
• Assume Active Detection: 0.008 USDT/unit

Plan	Steps	Total Cost (assumption)	Final Active Pool Size	Cost per Active User
A: Directly screen active	100k × 0.008 = 800 USDT	800 USDT	Approx. 25k (no open/valid filter)	0.032 USDT
B: Screen open first, then active	100k × 0.003 + 30k (assuming 30% open rate) × 0.008 = 540 USDT	540 USDT	Approx. 22k	0.025 USDT
C: Open → Valid → Active	100k × 0.003 + 30k × 0.005 + 23k × 0.008 = 484 USDT	484 USDT	Approx. 20k	0.024 USDT

Conclusion: Plan C (full funnel) has the lowest total cost, and the final “active pool” is the cleanest. Plan A, while consuming more active detection fees, may have numbers that are not open or invalid mixed in, resulting in worse actual reach.

So when can you skip a step?

• If the number source is reliable (e.g., pre-cleaned industry data), you can skip open detection and start from valid detection.
• If the goal is simply “fill the group with people” (e.g., brand exposure group), you can skip active detection.
• In short: Don’t blindly save on intermediate steps; make trade-offs based on number quality and marketing objectives.

Build Your One-Stop Filtering Funnel on KK-DATA

Understanding the theory is not enough; you need a practical platform to support the entire funnel. KK-DATA strings together “number generation → filtering → deduplication → export” in one line, letting you complete all steps in the same console.

Step 1: Prepare the Candidate Number Pool (Generate / Import)

• Global Number Generation: Covers random numbers and number range numbers from 240+ countries/regions. Generation is completely free.
• CSV Import: Upload your existing number list, supports custom number ranges.

After generation/import, numbers automatically enter the “Number Warehouse” for future reuse.

Step 2: Submit Filtering Tasks According to the Decision Tree Sequence

In the filtering module of the App Console, submit tasks in sequence according to your goal:

1. Select “TG Open Detection” → Set number pool → Submit task.
2. After task completion, select “Open” numbers from results → Click “Filter Again” → Select “TG Valid Detection”.
3. Continue on valid results → Select “TG Active Detection” → Customize activity window (7/15/30 days).

Key Tip: Enable “Deduplication Warehouse”. When you create a new task from a previous task’s results, KK-DATA automatically filters out already tested numbers, avoiding duplicate charges. For example, if you already screened for open, when screening for valid, the system will not waste fees on numbers that failed open.

Step 3: Export Conclusions and Mark Marketing Rhythm

After filtering, choose an export format (CSV / TXT). Based on detection results, you can divide users into:

• “Active Pool”: Mark as high priority, reach immediately (e.g., private message campaigns, community invitations).
• “Valid but Not Active”: Can be added to a long-term follow-up sequence, reduce contact frequency.
• “Not Open / Invalid”: Filter out, no longer waste resources.

This way, your marketing rhythm is no longer “spamming blindly”, but precise segmentation based on data.

Best Practice Checklist

Before submitting any filtering task, take 5 minutes to run through this checklist to avoid 80% of budget waste.

• Clarify marketing goal: Recruitment, mass messaging, or precision conversion? Different goals, different filtering sequences (refer to the decision table above).
• Assess number quality: Are numbers randomly generated, purchased, or old data? The poorer the quality, the more you need the full funnel.
• Estimate budget: Based on target audience size and detection unit prices, calculate estimated costs for each stage, ensuring sufficient balance.
• Enable “Deduplication Warehouse”: Prevents duplicate charges on the same number, especially when running consecutive detections.
• Set task notifications: Bind Telegram notifications via @kkdata_cc to know immediately when a task completes.
• Start with a test round: Before going full scale, verify funnel conversion rates with a thousand-level sample, then scale up.

Summary and Next Steps

Screen for open first or active first? The core principle is only one: Let the goal determine the sequence, and control costs with the funnel. Do not skip basic screening in pursuit of “active”, and do not only do the shallowest detection to save money. A good TG marketing funnel should be like a sieve, checking layer by layer, each layer reducing noise and increasing purity for the next.

Now, you can log in to the KK-DATA Console to start building your first filtering funnel. For help, please refer to the Official Documentation or contact customer service @kkdata_cc.

Frequently Asked Questions

Q: I only have a budget for 5,000 numbers. Should I screen for open first or directly for active?

A: It mainly depends on your marketing goal. If the purpose is “verify whether numbers are usable”, prioritize open detection (lowest cost); if the purpose is already “find recently online people”, it is recommended to first screen for open/valid to get a base pool, then screen for active from that, to avoid spending active detection fees on invalid numbers.

Q: I already have a batch of “valid numbers”. Can I directly screen for active?

A: Yes. On the KK-DATA platform, you can directly upload a valid number list (or select from the results warehouse of previous tasks), skip open/valid detection, and directly submit an active detection task. The prerequisite is that you confirm these numbers are still usable.

Q: What is the difference between choosing “7 days” and “30 days” when screening for active?

A: 7-day active means the user has been online within the past week, suitable for immediate outreach (e.g., time-limited events); 30-day active covers a broader range, suitable for long-term brand exposure or adding to regular follow-up sequences. When budget is limited, you can prioritize 7 days.

Q: Will the same number be charged twice if it is screened for open and later for valid?

A: If you follow the normal process on KK-DATA by creating a new task from a previous task’s results, the system automatically enables the “Deduplication Warehouse” and will not charge again for numbers already tested. However, if you manually upload the same original document twice, duplication may occur. It is recommended to always click “Filter Again” within the task results to operate.

Q: How can I view the estimated cost of a filtering task?

A: Before submitting a task, the console displays the estimated cost for that task based on the current number count and detection type. For specific unit prices, please refer to the Billing Page or the real-time display in the console.
