Remails

Remails delivers transactional email for developers through a clean API and modern SMTP — built on a Rust core for millisecond delivery and offered as both managed SaaS and a self-hostable open-source platform. Positioned as a European, privacy-first alternative to SendGrid, Postmark, and Resend, it keeps application email — password resets, receipts, notifications — under strict EU jurisdiction without sacrificing developer ergonomics.

The platform exposes native SDKs for Python, Node.js, PHP, and Ruby alongside standard SMTP for drop-in compatibility with any framework. Encryption is end-to-end: TLS in transit, AES-256 at rest, and a 100% open codebase that customers can inspect, audit, or run themselves. The managed service is backed by EU-hosted infrastructure, while the self-hosted option gives regulated industries total control of mail delivery.

Key benefits:

• Rust-based engine for millisecond-latency transactional delivery
• Open-source codebase fully inspectable, auditable, and self-hostable
• SMTP and API with SDKs for Python, Node.js, PHP, and Ruby
• TLS in transit, AES-256 at rest across the full delivery pipeline
• Managed or self-hosted deployment to match any compliance need
• EU-hosted infrastructure keeping mail under European jurisdiction

Remails is built in Europe with all managed infrastructure hosted inside the EU, keeping transactional mail under European data protection law. The platform is GDPR compliant by design, aligned with EU privacy regulations, and has ISO 27001 certification on its roadmap. Currently in beta and onboarding new clients with free test capabilities, it is a sovereign, open-source answer to US-owned transactional email incumbents.
