Million-Level Number Screening Comparison: How KK-DATA Handles Large-Scale Task Submission, Progress Monitoring, and Telegram Notifications?

Outbound marketing teams process hundreds of thousands or even millions of phone numbers daily, filtering out active Telegram/WhatsApp users before importing them into communities or direct messaging systems. In this process, task submission limits, real-time progress feedback, and automatic completion notifications are three pain points that are often overlooked but crucial for efficiency. If a platform can only handle tens of thousands of records at once, or requires manually refreshing the page for hours to get results, million-level screening becomes a nightmare.

This article uses Cows Data (a common batch number-screening tool) as a reference to compare KK-DATA’s actual capabilities in million-level screening scenarios — from task submission to result export and billing models — helping you decide which platform better suits your large-scale batch screening needs.

Why Million-Level Screening Demands Attention to Task Submission and Progress Management?

Imagine you export 800,000 phone numbers from an overseas e-commerce platform and want to batch-check WhatsApp validity. If the platform only allows 50,000 submissions per task, you’ll need to split it into 16 tasks, each requiring manual configuration, queuing, and waiting. Even worse, if the platform doesn’t support proactive notifications, you’d have to refresh the page every few minutes, wasting significant manual effort.

The three core requirements for million-level screening are:

• Large single-task capacity: Reduce the number of splits and lower the risk of operational errors.
• Real-time progress visibility: Know instantly how many have been checked, how many failed, and estimate remaining time.
• Task completion notification: Get automatic reminders when the job finishes, without staring at the screen.

Below, we compare Cows Data and KK-DATA across these three dimensions.

Task Submission Capability Comparison: Limits, Formats, and Workflow

Maximum Single-Task Volume: Bottlenecks vs. Breakthroughs at Million Scale

Comparison Item	Cows Data (Typical Configuration)	KK-DATA
Max numbers per task	Usually 100,000–500,000 (varies by version/plan)	Up to ~1,000,000 numbers
Automatic batch splitting	Requires manual splitting into multiple files and submitting one by one	Single submission, supports resumable upload (can resume if interrupted)

Cows Data typically requires splitting tasks at million-level scale, while KK-DATA supports up to ~1 million numbers per task. Simply prepare a CSV/TXT file and upload directly. If your number count exceeds 1 million (e.g., 2 million), split into two tasks, but each can still hold 1 million — much easier than splitting into ten.

Submission Process and File Requirements

• Cows Data: Numbers usually need to be in the first column, file encoding UTF-8, supports CSV and TXT. Some versions require manually selecting the country code, otherwise defaulting to +86.
• KK-DATA: Also supports CSV/TXT; number column position can be specified during upload (first column or any other column). Automatically recognizes international format (+ or 00) without manual country selection. Estimated cost is shown before submission; after confirmation, it enters the task queue.

Step-by-step comparison (using 500,000 WhatsApp checks as example):

Step	Cows Data	KK-DATA
1. Prepare file	Numbers must be in first column; dedup requires manual Excel	Any column is fine; dedup via built-in repository
2. Configure detection type	Select “WhatsApp Detection”; some versions require specifying thread count	Select “WhatsApp Screening” + export wsid
3. Submit task	Manually upload file, wait for queue to start	Upload file → Preview → Confirm cost → Submit
4. Task splitting	If over limit, system errors; manual splitting required	Single submission completes (≤1 million records)

Conclusion: KK-DATA offers a more streamlined submission process, especially when the number volume approaches the million mark — no need to worry about limits and splitting.

Progress Monitoring and Task Notification: Telegram Instant Feedback vs. In-Site Polling

Real-Time Progress Viewing: Dashboard vs. No Progress

Platform	Progress Display Method	Viewable Content
Cows Data	Most versions only show “Processing” with no specific numbers	None
KK-DATA	Online control panel with real-time progress bar	Checked count, success/failure count, estimated remaining time, current batch

KK-DATA’s task monitoring page works like a lightweight dashboard: you can see “Checked 324,567 / 500,000” along with failure reasons (e.g., invalid number format). Cows Data, in some older versions, doesn’t even have a progress bar — you just wait.

Telegram Notifications: Completion Alerts and Missed Alerts

This is KK-DATA’s overwhelming advantage.

• KK-DATA: After task completion, the system automatically sends a Telegram notification to your bound account (requires following @kkdata_robot as customer service). The notification includes: task name, detection platform, total records, valid count, invalid count, and duration. You can even set notifications for task failures or anomalies.
• Cows Data: Most versions do not support any proactive notifications. You need to repeatedly log in to check status. If a task runs for 3 hours, you must stare at the browser for 3 hours.

Real scenario: Submit an 800,000-record Telegram activity check at 10 PM. By 8 AM the next day, KK-DATA has already sent a Telegram message with results. With Cows Data, you’d need to manually open the webpage in the morning — and if the task hasn’t finished, you have to wait again.

Batch Management and Data Export: How to Efficiently Extract Million-Level Results

The export method determines whether the data can be directly used downstream.

Comparison Item	Cows Data	KK-DATA
Export format	CSV, TXT (some versions support)	CSV, TXT, customizable column names
Batch export	Not supported (exports entire file at once)	Supports batch export (e.g., one file per 100,000 records)
Export fields	Usually only number + valid/invalid	Number, status, activity level, gender, tgid, wsid, last online time, etc. (varies by platform)
Data reuse after export	Requires manual whitelist maintenance	Can import into dedup repository; next task can exclude already-checked numbers

KK-DATA’s advantages: Exporting tgid is very useful for Telegram community management — you can directly invite users via tgid or send messages. Also, batch exporting prevents downstream systems (e.g., CRM or email systems) from crashing when loading 1 million rows at once.

Cows Data is sufficient for basic screening, but if you need richer attributes (gender, activity window) or tgid, you’ll need a platform like KK-DATA that supports deep detection.

Billing Model Comparison: Per-Record vs. Package Plans — Which Is More Cost-Effective for Million-Level Tasks?

Comparison Item	Cows Data	KK-DATA
Model	Package plans (e.g., 100,000/500,000/1,000,000 records)	No subscription, pay per record
Remaining balance handling	Unused package records are wasted; insufficient requires buying another package	Balance is permanent; pay as you go
Price transparency	Package unit price often hidden (requires contacting support)	Real-time per-record price displayed in dashboard
Million-level cost	Must buy multiple packages, possibly wasting some quota	Estimated total cost shown before submission; top up if insufficient

KK-DATA is better for fluctuating task volumes: This month you process 100,000 records, next month 2 million. With pay-per-record, no need to worry about package sizes. Cows Data’s package model may be convenient for stable monthly needs, but if task volume drops suddenly, you’ll have waste.

Feature Completeness Comparison: Beyond Screening, Does It Offer Number Generation, Dedup, and Anti-Fraud?

A complete outreach process involves more than just screening: where do numbers come from? How to avoid duplicate checks? How to verify customer service authenticity?

Feature Module	Cows Data	KK-DATA
Number generation	Not supported (must purchase elsewhere)	Random generation for 240+ countries, prefix generation, custom CSV import
Data dedup	Only within-task dedup (auto-dedup within same file)	Cross-task dedup repository, permanently saves checked numbers to avoid repeat charges
Anti-fraud query	None	Official customer service verification (Unique Telegram account @kkdata_robot), can verify support authenticity
Multi-platform detection	Telegram, WhatsApp	Telegram, WhatsApp, iMessage, RCS, dead number/carrier (subject to dashboard availability)

KK-DATA provides a closed loop from “generate numbers” to “screen” to “export” , especially the number generation feature, which is very useful for teams needing many test numbers or A/B testing. Cows Data is weaker in additional features, focusing primarily on screening.

Frequently Asked Questions

Q: Can Cows Data handle million-level screening tasks? What’s the maximum per task?

A: Cows Data generally supports million-level tasks, but the single-task limit may be only 100,000–500,000 records, requiring manual splitting. Please refer to the platform’s dashboard for exact limits. KK-DATA supports up to ~1 million numbers per task and displays the estimated cost before submission.

Q: Which is better for batch screening, KK-DATA or Cows Data?

A: Both are suitable for batch screening, but they cater to different needs. KK-DATA is better for teams with fluctuating task volumes, needing Telegram notifications, and wanting a one-stop “generate + screen + dedup” solution. Cows Data may offer cost advantages for stable monthly needs under package plans. Choose based on your task volume, notification needs, and whether you want the “generate + screen” closed loop.

Q: How can I get results immediately after a screening task finishes?

A: KK-DATA automatically sends task completion notifications via Telegram (bind with @kkdata_robot customer service). Cows Data (and most similar tools) only support in-site queries without proactive notifications, requiring frequent page refreshes.

Q: Will the platform lag or crash after submitting a million-level task?

A: Reputable platforms like KK-DATA use distributed task queues, ensuring stable execution for million-level tasks. Before submitting, confirm if the platform has concurrent task limits. KK-DATA allows multiple tasks to run simultaneously per user — see the documentation for details.

Q: Which fields can be exported from screening results? Does it support exporting tgid?

A: KK-DATA supports exporting number status, activity level, gender, Telegram ID (tgid), WhatsApp ID (wsid), etc. Cows Data, in most versions, only exports numbers and valid/invalid status, not tgid. For specific fields, refer to each platform’s export options.
