Why does app send text messages to users through channels such as Chuanglan and Monternet? Can't you deliver it yourself?

First, the number of APP users is huge, and it takes a lot of time for APP operators to send text messages themselves.

Second, compared with the third-party platform, the number of short messages from users of non-platform APP operators is small, and without the support of telecom operators, the cost of self-sending is much higher than that of using third-party service platforms.

These two characteristics make it impossible for APP operators to send SMS to users independently.

None of the three major telecom operators supports customizing these activities/functions, and the third-party SMS platform can just solve these two problems.

Therefore, it is generally entrusted to a third-party SMS service platform to send.
