Sinch posted mixed Q2 results, with strong API-driven growth in the Americas offset by customer losses tied to a legacy verification product in Europe and operational headwinds in India that compressed gross profit margins.
Sinch's messaging and email API business continued to gain traction, particularly across North and South America, where developer adoption and enterprise demand drove solid revenue momentum. However, the gains were partially neutralized by two separate issues pulling in the opposite direction.
Key factors shaping the quarter:
The verification churn story is worth paying attention to. It reflects a broader pattern in the CPaaS space where legacy authentication products, particularly SMS-based OTP, are losing ground as enterprise buyers reassess their communication stacks.
For MSPs and telecom resellers, Sinch's quarter is a useful market signal on two fronts. First, API-native communication services are where enterprise spending is consolidating, and resellers who are not yet positioning around programmable communication layers risk being left out of those conversations.
Second, the European verification churn illustrates the risk of over-reliance on single-product revenue within a customer relationship. When a legacy product loses relevance, customers leave, and there is often nothing else to anchor them. This is exactly the dynamic that makes UCaaS reseller margins vulnerable when service stacks are too thin.
The actionable takeaway: Service providers should be evaluating which of their current offerings are in the same position as Sinch's legacy verification product. If a product is not evolving alongside customer needs, it is a churn risk, not a retention asset. Building layered service stacks, including AI voice capabilities, helps protect against this kind of single-point revenue erosion. If you are thinking about how to structure that, the MSP revenue stacking framework covers the strategic logic in detail.
Watch whether Sinch can accelerate the migration of European customers onto its newer platform products before the verification churn creates a longer-term revenue gap. For resellers, the broader question is how quickly the SMS-based authentication market continues to erode and what that means for any OTP-adjacent services in your own portfolio.
