Sinch: sovereignty score and 8 European alternatives

Sinch is a cloud communications provider offering messaging, voice and email through APIs and ready-made applications. Its range includes the Conversation API for messaging channels, a Verification API, business phone numbers, voice services, and email products such as Mailgun and Mailjet. Businesses use it to send notifications and marketing messages, to verify users and to run customer conversations. Sinch is delivered as a hosted service, accessed through a dashboard and APIs.

Sinch AB is headquartered in Stockholm, Sweden, and is listed on Nasdaq Stockholm. The company has offices in Europe, the Americas and Asia-Pacific. According to the legal terms of the Conversation API, the services may be hosted in various locations; the customer chooses the hosting location at setup, through the Sinch Dashboard or the account manager, and a later change may involve additional fees. The platform is proprietary. A European organisation should therefore settle the hosting location in the contract and check, for each product it uses, where data is processed.

Why digital sovereignty matters with Sinch

Sinch is headquartered in SE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Sinch hosts data in EU, US, APAC. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Sinch is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Sinch together with your other vendors and gives a total score, a heatmap and the main risk drivers.
