Sinch solves four critical problems martech platforms face at scale

Customer communications is core to the success of any martech company, and it comes with unique challenges. Here’s exactly how Sinch fixes each one.

Each new channel usually means another contract and vendor engagement. Sinch runs the full communication stack (messaging, email, verification, voice), so it’s less overhead and better pricing at scale for your team.

Messages fail silently and your customers are the ones to tell you. Sinch gives you real-time delivery monitoring and redundancy, plus direct engineer access, so you see the problem (and the reason) before the customer.

Switching providers is tricky when you have customers to keep live. Sinch offers white-glove migration support with a dedicated Technical Account Manager who moves your traffic without interruption.

Your customers want RCS, newly live on iOS and Android, but your team and/or provider(s) aren’t set up for it. Sinch’s Conversation API already supports RCS, and new channels won’t require a separate integration.

One platform

Replace fragmented tech with a unified foundation

One global company to run your messaging, email, voice, and verification instead of multiple vendors. 

  • The Conversation API covers SMS, RCS, MMS, WhatsApp, and nine other messaging channels through a single integration. 

  • Sinch’s Email API, Mailgun, handles email at scale – with list validation, inbox placement testing, and reputation monitoring built-in. 

  • Complete your communication stack with our Voice API and Verification API – IVRs, in-app calls, OTPs, and 2FA codes, on the same platform.

Deliverability

Catch failures before your customers do

On other networks, messages fail silently, and your customers are often the ones who tell you first. Sinch gives you visibility into every step, plus a safety net if something breaks.

  • Always-on delivery monitoring to show exactly when a message doesn’t land, and why

  • Sinch AI filters fraud across the network in real time, protecting your sender reputation before it affects delivery

  • Sinch Mailgun runs as a hot-standby parallel sending path, so traffic pivots automatically the moment your primary provider fails.

RCS Ready

Meet customer demand for the newest channel, RCS

Getting up and running with RCS means carrier registration, sender verification, and a separate integration for every carrier network. Sinch already handles that infrastructure, so you launch faster.

  • Verified messages with your customer’s logo, name, and brand colors

  • Rich features like buttons, images, and carousels, all within the native messaging app

  • Upgrade SMS messages to RCS automatically, with built-in fallback
