About
Sinch is an enterprise-grade communications platform offering a comprehensive suite of APIs and ready-to-use applications that enable businesses to connect with customers across every major channel. Its messaging APIs support SMS, RCS, MMS, and WhatsApp; its voice and video APIs handle calls, SIP trunking, and emergency services; and its email APIs power transactional and marketing campaigns through platforms like Mailjet and Mailgun. Beyond raw APIs, Sinch provides higher-level applications including a drag-and-drop Email Platform, a Chatbot Builder for conversational customer care, and a Contact Center solution. A dedicated Verification API lets companies protect accounts with OTP codes, phone number lookup, and multi-factor authentication flows. Built on the Sinch Super Network — described as the network that powers other networks — the platform offers direct, tier-1 global reach with enterprise-grade security and compliance built in. It serves use cases across marketing campaigns, transactional alerts, identity and fraud prevention, and post-sale customer support. Sinch integrates with major ecosystems including HubSpot, Shopify, Adobe, Emarsys, and SAP, making it easy to embed communications into existing business workflows without rebuilding infrastructure. It is equally suited for developers building custom integrations via API and for marketers or operations teams who prefer no-code applications. Plans scale from free trial access to full enterprise contracts, serving industries from financial services and retail to healthcare and telecommunications.
