Sinch
Messaging, voice and email APIs with a fully published per-country rate card
As of 31 August 2026, Sinch's pricing is not published; the vendor quotes on request. A publicly listed Swedish communications platform that publishes complete per-country, per-network prices in three currencies. Softwr lists it under Telecommunications. Sinch is made by Sinch AB, available on Web, API.
Overview
What Sinch does
Sinch provides SMS, RCS, WhatsApp, voice, verification and transactional email APIs to enterprises and software platforms. It trades on the Nasdaq Stockholm Large Cap list under the symbol SINCH, so its revenue, margins and retention are publicly reported rather than asserted in a sales meeting, which is rare in this market and useful diligence before a long contract. The practical reason to shortlist it is price transparency. Sinch publishes a full per-country and per-network rate card in US dollars, euros and sterling, with a stated price date, which puts it among the most complete public price lists of any vendor at its scale. Published US rates include one cent per message to the major American networks, a lower rate for registered 10DLC traffic, and outbound PSTN voice spanning roughly one to three and a half cents a minute depending on the route. That spread is the point: the number that determines your bill is the destination and network mix, not a headline rate, and per-message costs vary by more than an order of magnitude between cheap and expensive destinations. Its scale was assembled largely by acquisition, including Inteliquent for 1.14 billion dollars and Pathwire, bringing Mailgun and Mailjet, for around 1.9 billion, both closing in December 2021, MessageMedia at 1.3 billion in November 2021 and SAP Digital Interconnect for 225 million euros in 2020. Sinch itself rejects the reseller framing, describing 600 or so direct carrier connections built over twenty-five years rather than a software wrapper on someone else's network. Both things are true, and the question a buyer should actually ask is how uniform the console, API conventions and support feel across the specific products they intend to buy, because those products came from different companies.
What people use it for
- Enterprises consolidating messaging, voice and transactional email with one supplier
- Teams that need to model per-country cost precisely before committing to a vendor
- US voice traffic where termination on an owned network reduces cost
- Buyers who want a supplier whose financial position is publicly reported

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Sinch.
- Much of the portfolio arrived through acquisition, so a customer buying messaging and email should check how consistent the consoles, APIs and support processes actually are across those specific products.
- Product overlap from acquisitions means the right Sinch product for a use case is not always obvious and sales guidance varies.
- Integrating acquired businesses is a continuing programme, so account handling and support contacts can change under a customer mid-contract.
- The published rate card is a list price, so organisations at volume still negotiate and small senders pay the advertised rate without leverage.
- US A2P messaging carries 10DLC registration fees and per-segment carrier surcharges on top of the published rates, as it does with every provider.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Does Sinch publish its prices?
Yes, unusually completely for a vendor of its size. It publishes a per-country and per-network rate card in US dollars, euros and sterling, with a stated price date, covering both messaging and voice.
Is MessageBird part of Sinch?
No. MessageBird, now trading as Bird, is a separate Amsterdam company and a direct competitor. It does not appear anywhere in Sinch's own published acquisition history.
Can we see Sinch's financials before signing?
Yes. Sinch trades on the Nasdaq Stockholm Large Cap list under the symbol SINCH, so revenue, margins and retention are publicly reported.
