Telephone contact is an effective means to promote and stimulate customers repeatedly, but frequent use will cause customers' disgust! Appropriately contacting customers to visit (remember: it is important to send a sincere invitation letter), or visiting the customer company (remember: don't forget to write a thank-you letter after the visit), or writing a preliminary rectification plan to provide customers with the latest industry and government information, are all good ways to shorten the distance from customers.
The comprehensive use of holiday greetings, New Year greeting cards, Spring Festival gifts, team visits, etc. will make the customer relationship stable and sustainable!
