How to convey information to customers when new clothes are on the market?

Send a message to do these three steps, and you will be notified to your mobile phone:

Count the mobile phone numbers of users who often come to buy clothes into a spreadsheet excel, some of which can be exported.

2. Import the customer's mobile phone number into the box on the left side of the above soft interface, and then write the short message content into the content box and send it for 5 seconds. When customers know that there is a new model, they will come and try it on.
