Bring Your Business Closer to Your Customers with the Telekom SMS API and Our New Synesty Add-On - Logo

Emails are often overlooked or end up in spam folders, while SMS messages achieve significantly higher attention. According to an industry blog by GoSMS, around 84% of the global population owns a smartphone, and 41% of consumers prefer SMS over email.¹
Additionally, 9 out of 10 people regularly check their SMS inboxes, and over 72% read incoming messages within five minutes. These numbers show that SMS is the more direct, faster, and more reliable communication channel.
This makes SMS the ideal solution for time-critical notifications such as shipping information, appointment changes, or status updates.
Today, your customers expect fast and transparent communication.
With an automated workflow via the Telekom Synesty Add-On, you can turn this direct connection into a real competitive advantage. Messages like “Your order has been shipped. Here is your tracking number: …” can be sent fully automatically and reliably.
