The mobile phone number filtering process is optimized, and the batch processing efficiency can be more than doubled.
Mobile phone number filtering is not about simply deleting invalid numbers, but turning raw data into usable data that can be directly entered into marketing, customer service and private domain systems. Many teams used to process numbers and were used to manually guiding tables, manually removing duplicates, manually filtering, and then importing the results into the mass sending system. It can be maintained when the amount of data is small, but once it reaches tens of thousands or hundreds of thousands, the efficiency will drop significantly. The core of process optimization is not to make people operate faster, but to standardize repeated actions.
