One-click identification method for WhatsApp virtual numbers, how to avoid low-quality numbers during batch screening
One of the easiest pitfalls for many people when processing number data is that the proportion of virtual numbers is too high. The data seems to be a lot, and the screening has been done, but in actual use, there are few replies, weak reach, and even some numbers have no possibility of continuous use. The problem is often not quantity, but too many virtual numbers mixed in. If this layer is not screened out, no matter how you optimize the operation later, the effect will be difficult to stabilize.
