With one easy SMS API integration, you can also enjoy the benefits of our global reach and SMS-enable any application, website or system, facilitate international two-way messaging using long numbers and short codes, and more. For example, an e-commerce site may integrate an SMS API for authentication purposes as well as to send delivery status messages and notifications of special promotions; the education sector integrates an SMS API for reminders for exams and parent-teacher meetings as well as new student recruitment; retailers integrate an API for text messaging to increase foot traffic to their brick and mortar stores; and event organizers often use SMS API integration to confirm event details with attendees. SMS marketing costs significantly less than other advertising options such print, radio, or TV. That means that nearly every single text message sent is being opened. Bulk SMS is not only used for marketing purposes though. Many businesses use one-way SMS messaging to improve internal processes and communication between employees, for example, and financial institutions take advantage of the immediacy of SMS for time sensitive messages like one-time PINs.
