What does Sinch do?
Sinch is a communications platform that gives developers and businesses the APIs and tools to add SMS, voice, email, and video capabilities to their applications. Instead of building and maintaining direct connections to telecom carriers, you plug into Sinch's global network and get reliable delivery, routing, compliance, and fraud prevention out of the box. The platform also includes ready-made applications for marketing campaigns, customer care, and notifications — so teams that aren't coding can still send messages and run campaigns.
The backbone is the Sinch Super Network, a tier-1 infrastructure with over 600 direct operator connections, handling more than 100 billion calls and 700 billion texts and emails each year. This means messages reach handsets worldwide without going through middlemen. Sinch also layers in AI — called Sinch AI — to reduce fraud (like detecting suspicious traffic patterns) and to power smarter chatbots and conversational experiences. The APIs cover SMS, RCS, voice (including SIP trunking), email, and verification (one-time passwords, two-factor authentication).
Sinch is built for two main groups: developers who want to embed communication into their products, and marketers or customer service teams who need to send campaigns or support messages across channels. Real-world uses include sending appointment reminders, running SMS marketing promotions, verifying user logins, and building interactive voice response systems. It's a straightforward infrastructure play — reliable, scalable, and with enough flexibility to fit both small startups and large enterprises.
