The Short Message Service, or SMS, is still the most used messaging service worldwide, with access to all mobile phones.

SMS is a very reliable and flexible message protocol. In business, text messaging is a growing way to communicate with customers for sending reminders, notifications, activation links, two-factor authentication codes or alerts.

Sending text messages with our platform makes it possible to automate communication with your customers and give them that extra bit of service.

An SMS has a higher priority and sense of importance for customers than, for example, an email.
