Frequently asked questions
How is Sinch priced?
Pricing is pay-as-you-go and usage-based: SMS, voice, RCS and email are billed per message, minute or verification rather than per seat. Sinch publishes dedicated Global SMS and Voice pricing pages but no public rate card, so volume rates are negotiated with sales. There is a free trial, a free Docs MCP endpoint for developers, and no separate implementation fee is stated.
What does it take to integrate Sinch?
Integration is API-first. Developers sign up, get credentials and call REST APIs or SDKs for messaging, voice, email, verification and numbers, and can start in a sandbox before production. Sinch also ships a CLI, Skills, SDKs and an MCP server, plus prebuilt connectors for Salesforce, HubSpot, SAP, Microsoft Dynamics 365, Zendesk, Freshdesk, Shopify and Zapier.
Does Sinch support AI agents and MCP?
Yes. Sinch ships a self-hosted MCP server (npx -y @sinch/mcp) that exposes Messaging, Email, Numbers, Verification and Voice APIs as tools an agent can execute, plus a free read-only Docs MCP endpoint at developers.sinch.com/mcp for code generation. The server can run locally for data-sovereign environments and is listed in the Cursor marketplace.
Which compliance certifications does Sinch hold?
Sinch states ISO 27001 and SOC 2 Type 1 certifications, and says its voice platform meets GDPR, CCPA, STIR/SHAKEN, DORA, Kari's Law and RAY BAUM'S Act requirements. Calls use TLS signalling with SRTP media encryption, data at rest is AES-256, and a public Trust Center provides compliance documents. HIPAA and FedRAMP are not claimed on the pages reviewed.
Who is Sinch best suited for?
Enterprises and product teams that send high volumes of transactional or marketing messages across SMS, WhatsApp, RCS, email and voice, and that have engineering capability to work with APIs. Regulated sectors such as banking, fintech and healthcare use it for verified, compliant communications. Very small teams wanting a flat-rate, no-code marketing tool are a poorer fit.
