Subprocessors

Laatst bijgewerkt: 6 March 2026

Lettermint B.V. uses certain third-party subprocessors to assist in providing our services. A subprocessor is a third-party data processor who has access to personal data of our customers or their end-users in order to provide services to Lettermint.

This page provides important information about the identity, location, and role of each subprocessor we use. We will update this page from time to time to reflect changes in our subprocessors.

Current Subprocessors

This list is automatically synced with our Trust Center, powered by Vanta, a security and compliance platform that continuously monitors our infrastructure and processes. For full insights into our security posture, certifications, and policies, visit trust.lettermint.co.
