Telegram databases can be a goldmine for marketers—but only when the data is accurate, up-to-date, and relevant. Before launching any outreach campaign or adding user data to your system, it’s critical to validate Telegram data properly. Using invalid or poor-quality data can result in wasted resources, poor engagement, or even platform bans.
Let’s explore how to validate Telegram user data before putting it to work.
Why Telegram Data Validation Matters
-
Improves targeting accuracy
-
Reduces bounce or block rates
-
Ensures compliance with privacy standards
-
Boosts campaign ROI and credibility
Unvalidated data often contains bots, inactive users, duplicates, or irrelevant leads. Cleaning and verifying it helps you reach real people who are more likely to engage.
Step-by-Step: Validating Telegram Data
1. Check for Active Status
Use Telegram bots or tools that check user activity (e.g., “last seen recently”). Focus telegram data on users who:
-
Were online in the last 7–30 days
-
Are active in multiple groups
-
Have shared content or reactions
Avoid users marked as “last seen long ago”, as they may be inactive or deactivated accounts.
2. Filter Fake or Generic Usernames
Flag and remove:
-
Usernames like
user12345ortestacc01 -
Accounts without profile pictures or bios
-
Known spam bot usernames (check Telegram spam blacklists verifying your fax list for maximum deliverability if available)
Authentic users usually have real names, bios, and meaningful activity history.
3. Segment by Location or Language
Ensure your leads match your target region. Use:
-
Country codes for phone numbers (e.g., +44, +91, +880)
-
Language used in bios or group messages
-
Group/channel origin to infer cultural or geographic relevance
4. Remove Duplicates and Incomplete Entries
Clean your database with tools like Excel, Google Sheets, or Python scripts. Remove:
-
Duplicate user IDs or phone numbers
-
Entries missing critical data fields (e.g., username or group name)
-
Broken formatting or unreadable entries
5. Test Small Batches Before Scaling
Before using the full list, run test messages on a small batch. Measure:
-
Read/open rates
-
Response rate
-
Spam reports or blocks
This helps you avoid blasting unqualified leads and harming your fax lead sender reputation.
Final Tip: Validate for Quality, Not Just Quantity
A 5,000-user list that’s verified and engaged is far more valuable than a 50,000-user dump filled with bots. Take the time to validate your Telegram data—your future.
