Sinch

Global Cloud Comms

Global SMS-led CPaaS with strong RCS positioning.

Starting price* $0.0075/min voice

Overview

Sinch is one of the largest CPaaS providers by message volume globally, with particular strength in international SMS, RCS Business Messaging, and an expanding voice and video footprint. Through acquisitions (Pathwire/Mailgun, Inteliquent, MessageMedia, MailJet), Sinch now spans email, voice, messaging, and AI-driven engagement under one corporate roof.

Where Sinch is strong

  • Among the largest global SMS providers by volume
  • Strong early position in RCS Business Messaging
  • Owns Inteliquent (US voice carrier) for direct voice termination
  • Email (Mailgun, Mailjet) integrates into a unified comms stack

Where to be careful

  • Acquired portfolio means product surfaces and consoles aren't fully unified
  • Enterprise-led sales motion; less self-serve than Twilio or Plivo
  • Pricing transparency varies by region and product

Best fit

Enterprises with global messaging volume who value carrier relationships, RCS readiness, and a single vendor across SMS, email, and voice.
