How to call a sleeping customer to sell?

Call him, give him an ultra-low price activity and let him come to the store. When he comes, he will feel that the service is better than the old customers.

Since we are old customers, there should be a time conflict and we can't come. You can make an appointment for him.

Have a banquet or something, and find a place for your customers to communicate with each other. They will meet new friends at the event and will come again next time.

Satisfied, please adopt.
