More from Sinch
WhatsApp Business and Viber business messaging integrated alongside SMS / MMS / RCS — fitting buyers whose international customer base prefers WhatsApp / Viber over SMS in specific regions and whose CX strategy depends on the customer's preferred channel rather than channel-blind broadcast.
Email APIs via Mailgun (developer-grade transactional email) and Mailjet (transactional and marketing email) — fitting buyers whose deliverability, compliance, and analytics requirements are not met by app-bundled email and whose channel strategy consolidates email under the same operator that handles SMS, voice, and WhatsApp.
Voice APIs and global voice termination for app-embedded voice, programmable IVR, click-to-call, and conversation routing — fitting buyers whose voice-API needs span multiple geographies that single-region voice-API vendors cannot serve under one operator.
Verification and 2FA APIs covering SMS-OTP, voice-OTP, flash-call verification, and silent-mobile-network verification — fitting buyers whose authentication posture requires a global, multi-fallback verification layer rather than SMS-only OTP that breaks in low-coverage regions.
