Sinch —
Multi-Channel CPaaS for Messaging, Email & Voice APIs Under One Operator

Sinch fits operating models whose customer engagement spans messaging (SMS, MMS, RCS, WhatsApp, Viber), email at scale, and voice APIs — and whose previous CPaaS posture was stitched across multiple single-channel vendors with separate compliance, deliverability, and analytics layers. Strongest fit is retail, e-commerce, financial-services, healthcare, travel, and consumer-services operating models whose CX and marketing programs send high-volume transactional and promotional traffic and whose deliverability, compliance, and channel-mix economics depend on consolidating onto a single global CPaaS rather than running parallel SMS, email, and voice-API vendors.

Sinch delivers SMS / MMS messaging at global scale, RCS Business Messaging, WhatsApp Business and Viber messaging, email APIs (via Mailgun and Mailjet), voice APIs and global voice termination, verification and two-factor authentication, conversation APIs, and a Customer Communications Cloud unifying messaging, email, and voice under one operator with US-licensed entity (Sinch America LLC) and FCC carrier authorization.

Single-channel CPaaS vendors operate a strong product on one channel and stitch others through partnerships or acquisitions that have not converged on shared APIs, compliance, and analytics. Sinch operates across SMS / MMS / RCS / WhatsApp / Viber, email (Mailgun / Mailjet), and voice APIs as one operator with shared compliance posture, unified deliverability reporting, and consolidated billing — fitting buyers whose channel strategy spans messaging, email, and voice and whose operating cost is bottlenecked by managing multiple CPaaS vendors rather than by per-message pricing alone.

Yes. Sinch operates with the compliance posture required for HIPAA-aligned healthcare messaging, financial-services 10DLC and SHAKEN/STIR posture, and global regulatory frameworks (GDPR, TCPA in the US, regional consent regimes elsewhere). Buyers in regulated industries should scope their specific compliance requirements against Sinch's portfolio so the right product mix is selected — Fibi handles that scoping at no cost.

Sinch operates global voice infrastructure with carrier-grade voice APIs and termination across regions — fitting operating models whose customer base is multi-national and whose voice-API needs span multiple geographies that single-region voice-API vendors cannot serve under one operator.

No. Your service agreement is signed directly with Sinch and Sinch's standard customer terms apply. Fibi's role is to scope your messaging / email / voice-API objective against Sinch and the most relevant alternatives — including single-channel CPaaS vendors, native carrier 10DLC, and email-only or voice-only API vendors — so you see how Sinch's multi-channel posture compares before signing. Fibi's advisory work is provider-funded.
