Just because the number has been registered with Telegram, it does not mean that the user is still using it recently. If a customer list is mixed with a large number of long-term inactive accounts, the marketing team will still generate a lot of invalid sends and low-value follow-ups.
It can only confirm whether the account is opened, but cannot determine whether the user has been active recently.
Long-term offline accounts are mixed in the customer list, increasing ineffective marketing costs
Lack of last online information, unable to determine customer follow-up priority
Manually check the account status one by one, which is difficult to handle large batches of numbers
Users with different levels of activity cannot be stratified, and the marketing strategy is too unified
