The invention discloses a method, a device and an open platform for transmitting information, and belongs to the technical field of computers. The method for transmitting the information includes receiving requests for inviting second terminals to utilize specified application programs; detecting transmitted times of invitation information transmitted to the specified application programs in forced contact transmitting modes and judging whether the transmitted times of the invitation information reach first threshold values or not; transmitting the invitation information to the second terminals in the forced contact transmitting modes if detection results indicate that the transmitted times of the invitation information do not reach the first threshold values. The requests for inviting the second terminals to utilize the specified application programs are transmitted from first terminals. The method, the device and the open platform have the advantages that the quality of application can be judged by the open platform according service conditions of the specified application programs utilized by other users, the allowed utilization times of the forced contact transmitting modes are constrained according to the quality of the application, and accordingly effects of increasing the resource utilization rate of the open platform can be realized; the utilization times of the forced contact transmitting modes can be distributed according to the quality of the application, accordingly, application providers can be urged to continuously optimize the application, and high-quality service can be provided for the users.
