How does the official account platform of SMS WeChat occupy the marketing market?

Now people will leave contact information, that is, mobile phone number, when shopping, buying a house, buying a car and buying insurance online. Since you bought a house, various numbers will send messages telling you where to find a house with a good location. After online shopping, you will also do this routine. Of course, you usually leave a website or something. Once you click in, the SMS platform will be layered. If you buy something, the stratification will be greater. Although there are fewer messages sent now, you will find it still alive. The dynamic balance of the bank card reminds you when to return it to overdraft card. Compared with WeChat and QQ, the location of SMS still cannot be completely replaced, which is linked to the current national strategic Internet of Things. When there is no WIFI, SMS can still save lives. This is the advantage of the official account of SMS WeChat, which can quietly integrate resources. Of course, the network is expanding.
