Send transactional email, campaigns, and inbound mail from one self-hosted control plane. Keep your data in one SQLite file, choose SES, SMTP, direct MX, or local sandbox, and use a familiar developer-first API.
Hey Product Hunt 👋
I built sendthen because email APIs have excellent developer experience, but I wanted the control plane—and its data—to live on infrastructure I operate.
sendthen is an MIT-licensed, self-hosted email platform you can run as one container backed by one SQLite file. It covers transactional sending, audiences and broadcasts, inbound mail, visual templates, delivery events, webhooks, tracking, suppressions, and team/API-key management.
The key idea is transport freedom. Your app talks to the same API while you choose how mail leaves: Amazon SES, any SMTP relay, direct-to-MX, or a zero-network sandbox. It also includes a Resend-compatible REST surface plus a TypeScript SDK and CLI.
You can try the hosted version, self-host with Docker, or inspect every line on GitHub.
I’d especially love feedback on:
• Which transport do you use today?
• What would make self-hosting email infrastructure feel trustworthy?
• Where does the API diverge from the developer experience you want?
Thanks for checking it out. I’ll be here throughout launch day to answer questions.
