The source of data for communication with customers, partners or clients are mostly corporate systems, whether business, marketing or operational. Data for customer communication are generated synchronously or asynchronously from these systems. They are than processed and sent via various application interfaces and protocols. In some cases, it makes sense to use a graphical user interface that allows friendly work with data, individual campaigns and customer reactions. At the same time it is important to ensure all the necessary processes for personal data protection and protection against misuse (spam, fraud, etc.). In addition to the above-mentioned functionalities, the SMS gateway also provides administration of individual gateway users, traffic statistics and many other functions.
