How to screen Telegram accounts registered with a mobile phone number for activity? Methods for accurately identifying highly active accounts.

Those involved in overseas promotion or cross-border business know that Telegram is increasingly used for marketing, sending notifications, and customer service. However, with a large number of phone numbers, how do you distinguish which Telegram accounts are actually used by active users and which are long-dormant "zombie accounts"? This is what we commonly refer to as the Telegram activity filtering  problem. Without a good  Telegram activity filtering system , a large portion of your marketing messages may end up being sent to accounts that never read them, resulting in wasted money and no effect. Today, let's discuss a simple and effective method to identify truly active and high-quality accounts. 

Why is simply knowing "whether or not you have registered" far from enough?

Many people's first step is to check if the phone number is registered with Telegram. If they find it, they think, "Great, this number works!" But reality is often a slap in the face.

Several common types of "scam" accounts:

• Register and then leave it unattended : Many people are just curious to download an app, register, and then never open it again.
• "Lurkers" who only check messages once a month : These users rarely read messages, so they won't see your ads at all.
• Accounts that have already been banned : The account has been banned for posting advertisements or violating regulations, but the phone number is still in your list.
• Fake accounts registered by machines : They are obviously mass-produced and not real people at all.
• A temporary account : used and discarded, it has no long-term value.

Mixing these accounts with highly active users and sending indiscriminate push notifications will lead to a serious waste of marketing budget, distortion of key metrics, and low operational efficiency. Therefore, establishing a scientific Telegram activity screening  system is crucial. 

How do I determine if an account is "recently" active?

The simplest and most important way to tell if an account is active is to see if it has been active "recently". "Recently" here doesn't just mean today; it means looking at a period of time.

You need to figure out these things:

• When was this user last logged in?
• Based on his online frequency, can we determine whether he is "highly active" (uses it every day), "medium active" (uses it a few times a week), or "lowly active" (uses it a few times a month)?
• Now that I know his activity level, should I message him immediately, or should I let him rest for a while?

If you ignore these time patterns, your operations will run into all sorts of problems:

• Send a limited-time coupon to someone who hasn't logged in for three months.
• Having customer service focus on an account that has been dormant for a long time is a waste of manpower.
• When configuring automated bot tasks for inactive accounts, all results were "failed to send".
• Stuffing all phone numbers, whether active or not, into a customer relationship management (CRM) system increases time costs.

Note that each number has a different value. It's best to categorize numbers based on their activity level and operate them using different strategies.

Besides the time of launch, what other behaviors can we observe?

To determine if a user is truly active, you can't just look at when they log on. What they "do" on Telegram is more important. It's like judging whether someone frequently goes shopping; you can't just see if they enter the mall, but also whether they buy anything or chat with friends.

You can observe these behavioral patterns:

• Which groups have you joined? Do you chat in them?  An active user usually joins some groups that interest them and occasionally says a few words.
  
• Is your profile complete?  Have you carefully set a profile picture, chosen an easy-to-remember username (@username), and written a brief bio? People who are willing to spend time decorating their accounts are more likely to be genuine users who intend to use them long-term.
  
• How do you prefer to chat?  Do you only type text, or do you frequently send emojis, pictures, and files? The more features you use, the more proficient you are at using the app and the higher your activity level.
  
• Do they actively seek out people to chat with?  Highly active users don't just passively receive information; sometimes they also proactively send private messages to others or create small groups to discuss things.

Of course, it's impossible for us to manually check the behavior of thousands of accounts. That's where technical tools come in, helping us to analyze them quickly.

Use the right tools to save time and effort in batch filtering.

With a massive number of phone numbers, manually assessing activity levels is virtually impossible. Professional tools can automate and batch-filter, significantly improving efficiency. Taking ITG's full-domain filtering  as an example, the system automatically assigns clear activity tags to each phone number through multi-dimensional analysis: 

The system will automatically detect and mark the following active states:

• High activity level : Users who have been online within the past 24 hours will be prioritized for reach.
  
• Medium-active : Has been online within the past 3 days and can be reached normally.
  
• Lightly active : Has logged in within the past 7 days; requires appropriate guidance.
  
• Cold Inactivity : If an account has not logged in for more than 7 days, a reactivation strategy is required.
  
• Unreachable : Status unknown or abnormal; exclusion recommended.

Each phone number is precisely categorized and tagged with corresponding activity tags, forming a structured, hierarchical database. These categorization results can be directly:

• Export to an Excel spreadsheet, then perform subsequent operations manually.
• Integrate with SCRM system to achieve customer tiered management
• Connect to a group control system and implement differentiated marketing strategies based on activity levels.
• Synchronize the customer service system and optimize the allocation of service resources.

Through this systematic filtering and classification, the originally chaotic list of numbers is transformed into a precise resource library that can be accessed on demand.

Conclusion:

To avoid wasting money on Telegram marketing, screening for active users  is absolutely essential. Don't just be satisfied with knowing "this account is registered"; ask, "Is the owner of this account actually using it?" From analyzing online time and observing behavioral patterns to using professional tools for batch screening, every step is about precisely targeting valuable marketing resources to real users who are likely to read and respond. Master this fundamental skill, and your conversion rate and ROI will naturally increase.
