Opensend: Self-hosted transactional email, newsletters, and campaigns with SES OpenSend launched as a self-hosted platform for transactional email, newsletters, and campaigns built on Amazon SES, distributed via the GitHub repository R44VC0RP/opensend. The project uses Google-only sign-in with no passwords or teams, and exposes a single public API shared by its dashboard, SDK, and MCP server, with the opensend-js package installable from npm. Setup is offered through Docker or Cloudflare, or by pasting a guided prompt into a coding agent that reads api/README.md first.

Open the repo in your coding agent and paste: Help me set up OpenSend for my use case. Explore this repo and read api/README.md first. Ask what I want to send, whether I prefer Docker or Cloudflare, and what infrastructure I already have. Recommend the simplest setup and explain the plan before making changes. Use my own accounts and resources, keep secrets out of git, and start with simulated sending. Ask before provisioning, deploying, or sending real email. Prefer a manual setup? Start with Docker /R44VC0RP/opensend/blob/main/api/README.md docker-quickstart or Cloudflare /R44VC0RP/opensend/blob/main/api/README.md cloudflare .
