Lettermint
Your European partner for transactional emails that arrive.
Lettermint is a European transactional email delivery service that helps businesses ensure important emails—such as order confirmations, password resets, and account verifications—reach recipients’ inboxes reliably. It solves the problem of poor deliverability and data privacy concerns by operating entirely on EU infrastructure, complying with GDPR, and holding ISO/IEC 27001:2022 certification.
The service offers SMTP relay, a REST API, and official SDKs for languages including PHP, Node.js, Python, Go, Java, Rust, Elixir, and .NET. It also provides integrations with platforms like WordPress, Laravel, Symfony, Zapier, Make, Magento, Stripe, and Terraform, plus a CLI and an MCP server for AI tools. Key capabilities include sending transactional and broadcast emails, processing inbound emails via webhooks, managing multiple domains, and accessing analytics on delivery, open, and bounce rates.
Lettermint is designed for developers, startups, agencies, and enterprises that need a privacy-focused email delivery partner. It offers a free plan with 300 emails per month and no credit card required, along with paid plans that are seat-based with unlimited users and additional email blocks. Users can upgrade, downgrade, or cancel at any time.
