useSend is an open source email sending platform that provides an alternative to commercial services like Resend, Sendgrid, and Postmark.
The tool addresses the need for a self-hosted, cost-effective email infrastructure by leveraging Amazon SES under the hood while providing a user-friendly dashboard and management interface. It handles transactional emails, marketing campaigns, and contact management with subscription handling built in. The platform offers both REST API and SMTP support, allowing developers to integrate email sending into applications through their preferred method. A visual email editor and webhook support enable flexible workflow integration.
Teams should consider useSend if they want to avoid vendor lock-in, reduce email sending costs, or need to self-host their email infrastructure. It suits projects ranging from transactional email needs to newsletter and bulk email campaigns. The tool is currently in beta, so adoption should account for ongoing development and potential breaking changes as it moves toward production readiness.
Development activity shows the project is actively soliciting community feedback through discussions and a Discord server, with explicit calls for testing and issue reporting to reach production release. The maintainers are transparently tracking work needed for the first production release and welcoming contributions to address identified gaps.
