Welcome to the future of transactional mailing

We’re proud to introduce Lettermint: the European platform for transactional emails. Built by developers, for developers — with a focus on fast integration, full control, and the confidence your emails get delivered.

Easily integrate Lettermint into your existing software or app and send transactional emails like password resets, order confirmations, payment receipts, and account notifications. In addition to SDKs for PHP, Node.js, Laravel, and SMTP. Lettermint offers a developer-friendly API that makes it easy to build your own integrations or custom solutions. We're actively working on support for more languages.

A European email provider — from infrastructure to support

Lettermint is fully European. From our infrastructure to our support, everything operates within Europe. We don’t store any data outside the EU and fully comply with the strictest privacy regulations, including the GDPR. There’s a growing demand for reliable European alternatives — and Lettermint is our answer, without vague detours or compromises on privacy.

As demand for privacy-friendly European alternatives continues to grow, Lettermint stands ready. With our own infrastructure, we deliver the solution.

What makes Lettermint different

• Infrastructure hosted entirely within the EU
• Fully GDPR-compliant
• No reliance on US-based cloud providers
• Transparent data processing and storage
• Full control over your data
• Support based in Europe, in your own timezone
