Telegram Filtering Checklist: 7 Steps to Clean Your Contact List Before a Marketing Campaign

If you’re planning a Telegram marketing campaign—whether it’s direct message promotion, community recruitment, or brand notifications—you likely have a list of phone numbers. But how many of those numbers are actually registered on Telegram? How many users have been online recently? How many are duplicates?

The Telegram filtering checklist is designed to answer exactly these questions. It’s a repeatable list-cleaning process that helps you perform key steps before your campaign: validating number registration, filtering by activity, gender identification, deduplication, and more. This ensures you don’t waste messages on invalid, inactive, or duplicate numbers, saving your budget, reducing the risk of account bans, and improving conversion rates.

This article will walk you through all 7 steps, from registration validation to exporting and grouping, with best practices for different scenarios. Whether you’re using a Telegram filtering tool for the first time or optimizing your existing workflow, this pre-campaign checklist will provide actionable guidance.

What Is the Telegram Filtering Checklist and Why Must You Execute It Before a Campaign?

Simply put, the Telegram filtering checklist is a systematic guide to cleaning your contact list before launching a marketing campaign. Its core goal is to remove three types of invalid data:

• Unregistered numbers: Numbers that don’t exist on Telegram—sending messages to them is like shouting into the void.
• Inactive users: Users who registered but haven’t logged in for a long time; your message may never be seen and might even be flagged as spam.
• Duplicate numbers: The same number appearing multiple times in your list, causing double charges and distorted statistics.

Without this checklist, your campaign risks: wasted budget (charged for invalid numbers), lower-than-expected results, and account suspension due to reports. By performing a one-time cleaning, you can focus your delivery resources on truly valuable targets.

Pre-Campaign Step 1: Registration Validation – How Many “Dead Numbers” Are in Your List?

Any effective list cleaning starts with confirming whether each number is registered on Telegram. If you skip this step, you might send messages to hundreds of thousands of nonexistent numbers, wasting your billing balance and potentially getting your account rate-limited due to failed delivery requests.

How Registration Detection Works and Steps to Perform It

In the KK-DATA console, this feature is called tg开通 (registration check). It works via simulated login verification or API queries (without revealing internal details), returning whether each number is registered on Telegram.

Steps:

1. Log in to the App Console.
2. Click “New Filtering Task,” select Telegram platform.
3. In detection type, check tg开通.
4. Upload your number file (CSV, TXT supported; up to ~1 million numbers per batch).
5. Confirm the estimated cost and submit the task.
6. Once complete, results are automatically saved and can be exported.

How to Interpret “Registered” vs. “Unregistered” Results

The result table includes a field like tg_open. A value of 1 means the number is registered on Telegram, 0 means unregistered. Simply filter for tg_open=1 and use those numbers for further activity filtering or direct marketing. Unregistered numbers can be discarded or kept for validation on other platforms.

Pre-Campaign Step 2: Activity Filtering – Are Your Target Users Actually “Online”?

Even if a number is registered, the user may not be recently active. Sending messages to users who haven’t logged in for months or even years means very low visibility and may harm your account’s reputation. Activity filtering lets you keep only users with recent activity.

Why Specify Activity Days? How to Choose Based on Scenario

KK-DATA supports custom activity windows like 7 days, 15 days, 30 days. Recommendations for different marketing scenarios:

Scenario	Recommended Activity Days	Reason
Direct message promotion (offers, notifications)	7 days	Highest probability of message read
Community recruitment (invite to groups)	15 days	Balance between reach and list size; avoid over-filtering
Brand notifications (product updates, event announcements)	30 days	Brand messages have higher tolerance; cover more potential users

Combining Activity Filtering with Gender Detection

You can check both tg活跃 (specify days) and Gender Recognition (AI-based from profile photos) in the same task. This gives you a single list with activity level and gender labels. When exporting, you can group by “active + male,” “active + female,” etc., for more precise targeting.

Pre-Campaign Step 3: Deduplication – Why Must You Do This Before Cleaning?

Suppose you have numbers from multiple sources: your own generated numbers, purchased data, or historical campaign users. These lists likely overlap. Without deduplication, the same number will be detected multiple times, causing double charges and distorted statistics that hurt your ROI analysis.

KK-DATA’s Deduplication Repository supports cross-task deduplication. Simply import each task’s results into the repository. When you upload new numbers for a subsequent task, the system automatically identifies and skips already detected numbers (using hash comparison, never exposing the original numbers). Recommendations:

• Before starting a new campaign, import your historical valid numbers into the deduplication repository.
• When submitting a filtering task, enable the “Use Deduplication Repository” option to automatically filter out already-checked numbers.

Pre-Campaign Step 4: Confirm Balance and Task Budget

Before submitting a filtering task, make sure your account balance is sufficient. KK-DATA charges per query with no subscription plans. The system shows an estimated cost before submission. If your balance is insufficient, the task cannot be submitted.

To view real-time unit price and balance:

• Check the Pricing page in the console or billing section.
• Your balance is displayed at the top of the console.

Pre-Campaign Step 5: Exporting and Grouping – How to Use the Results?

After a filtering task completes, results can be exported as CSV or TXT. The exported data includes all detection result fields. How to leverage this data for subsequent marketing:

1. Group by activity: Export numbers with “7-day activity” separately for high-priority delivery.
2. Group by gender: If gender recognition was used, export “active + male” and “active + female” separately with different copy.
3. Cross-platform merging: You may later need to run detection on WhatsApp or iMessage as well. You can cross-filter across platforms.

How to Integrate This Checklist into Your Daily Marketing Workflow?

Institutionalizing the checklist can significantly boost team efficiency. Recommended pipeline:

1. Number Acquisition: Use generation modules (240+ countries) or your own channels.
2. Import to Dedup Repository: Avoid double detection.
3. Registration Check: Filter out unregistered numbers.
4. Activity + Gender Detection: Get core filtering results.
5. Export and Group: Save by target dimensions.
6. Confirm Recharge: Ensure sufficient balance.
7. Execute Campaign: Use pipeline or direct-send tools to push messages to cleaned numbers.

This process can be executed weekly or biweekly to continuously improve list quality. Use KK-DATA’s task template feature (if available) or manually record task IDs for easy traceability.

FAQ

Q: Do I have to perform all steps in the checklist every time for a campaign?

A: Not necessarily. If your list is freshly generated and hasn’t been mixed with old data, you can skip deduplication. However, if your list is from previous campaigns or purchased, it’s strongly recommended to run all three: dedup + registration + activity to ensure data quality. Choose 7 or 15 days for activity based on your campaign urgency.

Q: Is the activity detection accurate? Could it miss active users?

A: Activity detection is based on the user’s last seen time publicly available and is generally accurate. However, some users enable privacy settings (e.g., “Hide Last Seen Time”), making their actual activity unretrievable. To reduce misses, consider setting a wider activity window (e.g., 15 days). You can choose to keep or discard those privacy users.

Q: Does the deduplication repository store my historical numbers? Is it secure?

A: The deduplication repository stores only the hash value (one-way encryption) of numbers; the platform cannot retrieve the original numbers. You can clear your deduplication history at any time in the console. All data transmission and storage comply with industry security standards.

Q: Can I perform the pre-campaign check on mobile?

A: The KK-DATA console is web-based, best used on a desktop browser for bulk uploads and task management. You can view task status and export results on mobile, but handling large lists (e.g., hundreds of thousands) is not recommended on mobile due to poor upload and editing experience.

Q: What if my balance doesn’t update after recharge?

A: USDT (TRC20) recharges usually arrive within minutes. If it hasn’t updated after a long time, contact support via the bot (https://t.me/kkdata_robot) with a transaction hash screenshot. Support will assist. Double-check the network type before sending.
