The radiation and penetration of modern science and technology influences the legislation, judiciary and law enforcement in China. In order to fit the lawsuit idea and meet the needs of judicial reform, the Civil procedure law establishes the electronic service system including the email service. The system embodies the “rights-based” concept of civil litigation and reflects the value function of the service system which guarantees the validity of litigation behavior. But there is no clear norm for the guidance of the operation of the system at present, and the rate of email delivery is still unable to achieve the degree of no loophole. Optimization of the legal norms should be made to make up for defect of technical rules. The email delivery should receive the written consent of addressee in principle. The delivery of documents are completed by both scribes and technicians. It is necessary to introduce the instant reply and instant delivery system, and a system to impede the legal liability. The court owns the decision making right to the email service, and should fulfill obligations such as moderate review and risk disclosure.
