Multi-Channel Campaign Preparation: Cross-Platform Number Screening Checklist to Boost Overseas Customer Acquisition Efficiency

Multi-channel campaigns (simultaneously covering Telegram, WhatsApp, iMessage, and other platforms) have become a common strategy for overseas customer acquisition. However, many teams overlook a critical step before execution: screening and preparing high-quality phone numbers. Numbers that haven’t been cross-platform verified can lead to low reach rates, wasted resources, and increased operational costs due to a large number of invalid numbers. This article provides a complete cross-platform number screening preparation checklist to help you quickly lock in effective targets and improve ROI in multi-channel campaigns.

Step 1: Define Campaign Goals and Target Platforms

Different campaign types have very different requirements for number quality. Before starting number screening, answer these three questions:

• Purpose: Is it for direct message promotion, community invitations, or customer reactivation?
• Target Market: Which countries or regions? Does it involve multi-language operations?
• Platforms Used: Telegram, WhatsApp, iMessage, RCS, or all of them?

Number Quality Requirements by Platform

Platform	Key Detection Parameters	Usage Scenario Description
Telegram	Registration check, activity (7/15/30 days), gender identification	Community management, DM outreach, female/male targeted campaigns
WhatsApp	Valid number detection, wsid export	Broadcast messages, customer notifications, CRM integration
iMessage	Carrier match, validity	iOS user reach, brand messaging
RCS	Carrier support, empty number detection	Android users, rich media message promotion

For example: If you plan a Telegram community growth campaign, you not only need to confirm the number is registered but also determine if it has been active recently (e.g., within 7 days) to avoid sending to many zombie accounts. WhatsApp campaigns, on the other hand, focus more on whether the number is a valid WhatsApp user and whether wsid can be exported for subsequent API use.

Estimate Target Quantity and Budget Planning

Suppose you plan to ultimately obtain 10,000 active users through a multi-channel campaign, with 60% from Telegram and 40% from WhatsApp. Based on experience data (Telegram average activity rate ~30%–50%, WhatsApp effective rate ~70%–85%), you need to prepare:

• Telegram: Target 6,000 active → Generate approximately 12,000–20,000 numbers
• WhatsApp: Target 4,000 effective → Generate approximately 5,000–6,000 numbers

It is recommended to prepare total generation quantity as target × 2–3 times. Screening costs are calculated based on each platform’s unit price (see real-time prices in the console). The system will display an estimated fee before submitting a task; it is recommended to recharge sufficient balance in advance to avoid interrupting the campaign.

Step 2: Global Number Generation – Prepare Sufficient Number Sources for the Campaign

Number generation is the starting point of the screening pipeline. KK-DATA offers a Global Number Generation feature, supporting random generation for 240+ countries/regions, as well as generation by number segments or uploading custom CSV imports.

Generate Precisely by Country and Number Segment

• In the console’s “Number Generation” module, select target countries such as the US, India, Indonesia, etc.
• You can also restrict number segments (e.g., US +1 (xxx) segment) or upload a CSV (one prefix or full number per line).
• It is recommended to focus generation on the campaign market, e.g., for Southeast Asian campaigns, prioritize generating numbers from Indonesia, Philippines, and Thailand to increase subsequent screening hit rates.

Free Generation, Pay-per-Screening – Cost Control Strategy

Generation steps consume no balance; charges only apply per record when a screening task is completed. Therefore, the best practice is to first generate a large enough number pool (e.g., 100,000 records) and then screen in batches. Insufficient balance will prevent submission of screening tasks, so remember to recharge in advance.

Step 3: Cross-Platform Batch Screening – Verify Validity, Activity, and Gender

After generating numbers, proceed to the core step: cross-platform batch screening. On KK-DATA, you can submit a single task containing detection parameters for multiple platforms, and the system will automatically process them in parallel.

Telegram Screening: Registration, Activity Window, and Gender Identification

• tg_open: Checks if the number is registered on Telegram; this is the most basic filter.
• tg_valid: Further confirms the number can receive messages (no abnormal restrictions) after registration.
• tg_active: Can specify activity within 7, 15, or 30 days, suitable for high-frequency outreach campaigns. If targeting new users, choose 30 days; if seeking immediate feedback, choose 7 days.
• Gender identification: Identifies gender via avatar AI models, used for female-priority or male-targeted campaigns.

WhatsApp Screening and wsid Export

WhatsApp screening mainly confirms whether the number is registered on WhatsApp. When exporting results, check the wsid (WhatsApp ID) option. The wsid can then be directly used with WhatsApp Business API or third-party interfaces without needing to query the user ID again.

Step 4: Data Deduplication Repository – Avoid Wasting Balance on Duplicate Checks

In multi-round screening or team collaboration, the same number may be submitted for detection repeatedly, wasting balance. KK-DATA’s Data Deduplication Repository automatically identifies already detected numbers to prevent duplicate charges. Usage is simple:

1. Go to the “Deduplication Repository” in the console.
2. Import your existing number library (the system automatically compares with historical detection records).
3. When submitting a new task, the repository automatically excludes already detected numbers, charging only for undetected ones.

Step 5: Export Screening Results and Feed into Campaign Tools

After screening is complete, you can export CSV or TXT files containing the following fields:

• Phone number (with international code)
• Platform detection results (e.g., Telegram registered, activity level, gender)
• tgid / wsid (export only, depends on task selection)
• Other custom markers

After exporting, adjust column order and delimiters (comma or tab) according to the format requirements of your campaign tools (e.g., Telegram bulk messaging software, WhatsApp broadcast system). For example, many tools require a format like “phone number, username” or “phone number, wsid”; KK-DATA’s export supports custom field arrangement.

Step 6: Execution and Monitoring – Task Notifications and Balance Management

After submitting a screening task, you can enable Telegram Notifications to automatically receive the result link upon completion. Once results are received, immediately check data quality (e.g., whether the activity rate meets expectations). Adjust filtering parameters if necessary (e.g., increase the activity day threshold) and generate/screen the next batch of numbers.

Balance management is equally important. The console displays your current balance and the estimated fee for each task. If the campaign spans a long period, it is recommended to recharge and screen in batches to avoid a large one-time investment.

Implementation Summary and Best Practices

• ☐ Generate sufficient numbers in advance: Generation is free; generate more and then screen.
• ☐ Use the deduplication repository: Automatically deduplicates across tasks, saving costs.
• ☐ Screen in batches: Keep individual tasks under 1 million records (platform limit); recommend testing small batches of 100,000–200,000 at a time.
• ☐ Keep failed numbers: Numbers that are not registered/active may still be valid on other platforms (e.g., WhatsApp valid but Telegram invalid); save them separately for later use.
• ☐ Preview fees: Always check the estimated charge before submitting a task to avoid interruption due to insufficient balance.
• ☐ Adjust activity window per campaign pace: Use a loose threshold (e.g., 30 days) for the first screening, then tighten to 7 days for subsequent rounds to improve reach quality.

Frequently Asked Questions

Q: How many numbers should I prepare before a multi-channel campaign?

A: It depends on the campaign type and reach rate targets. For example, if you want to ultimately obtain 10,000 active Telegram users, based on the platform’s average activity rate of 30%–50%, you need to first generate 20,000–33,000 numbers and screen to get valid samples. It is recommended to prepare target quantity × 2–3 times.

Q: How can I avoid unnecessary costs during cross-platform screening?

A: Use the deduplication repository to avoid duplicate checks; generate a large number pool first (free), then screen in one go; prioritize screening high-profit platforms (e.g., iMessage/RCS) or screen lower-cost platforms first based on unit price.

Q: Can screened numbers be directly used for Telegram bulk messaging?

A: Yes. When exporting CSV, include fields like tgid, phone number, and activity level. Most bulk messaging tools support import. However, be sure to comply with platform rules to avoid account bans from sending too many messages in a short period.

Q: Should I screen all platforms simultaneously for a multi-channel campaign?

A: You can submit tasks for multiple platforms at once (e.g., screen both Telegram and WhatsApp in one task), but it is recommended to first test a small batch on a single platform to confirm data quality before scaling up.

Q: How should I configure number generation and screening if the campaign covers multiple countries?

A: Select target countries and number segments during generation. During screening, platform detection is performed per country, and the exported results retain the country code. It is recommended to export grouped by country for easier regional operations.
