Why can Taobao send advertising messages to itself after shopping?

Because you bought something in this store and left your address and phone number, as long as there is activity in the future, the merchant will automatically send a text message to tell you that there is activity in his store through a software.

Taobao is a large online retail and business circle in the Asia-Pacific region, which was founded by Alibaba Group in May 2003. Taobao is a popular online shopping and retail platform in China, with nearly 500 million registered users and over 60 million regular visitors every day.

By the end of 20 1 1, the daily turnover of Taobao reached 4.38 billion yuan, creating 2.708 million direct and full employment opportunities. With the expansion of Taobao's scale and the increase of users, Taobao has also changed from a single C2C online market to a comprehensive retail business circle including C2C, group purchase, distribution and auction. It has become one of the global e-commerce trading platforms.
