What is Sinch and why do businesses look elsewhere?
Sinch is a CPaaS (Communications Platform as a Service) provider based in Stockholm. They handle SMS, voice, email, and WhatsApp APIs for businesses that need to communicate with customers at scale. With over 4,000 employees and operations in 60-plus countries, they are certainly not small.
But size does not always mean the best fit. Here is why businesses start searching for Sinch alternatives:
- Pricing transparency: Users often mention that Sinch's pricing structure is hard to forecast, with unexpected costs popping up
- Support quality: Slow or inconsistent support responses are a common complaint
- Developer-heavy platform: Non-technical users sometimes struggle with the interface and setup process
- Fragmented experience: Multiple portals from various acquisitions can make navigation confusing
If any of these sound familiar, it might be time to explore what else is out there.
