An open-source email platform for sending transactional and marketing messages, available for self-hosting or as a cloud service. It helps teams avoid per-message API billing and vendor lock-in by providing owned infrastructure for developer-focused email workflows. Intended for developers, businesses, and marketers who can work with code-based setup rather than a pure no-code tool.
