The stack

“Convex is the backend of opensend.cc, self-hosted right next to the app. It stores every email, event and contact, and it serves the REST API. Its realtime sync is why the dashboard updates the moment an email is opened or clicked, without a refresh.” — the maker, Sep 2026 ↗

“The opensend.cc dashboard is built with Next.js. It ships as one Docker image that the installer pulls and runs on your server. Domains, emails, broadcasts, templates and automations all live in that one app.” — the maker, Sep 2026 ↗

“opensend.cc sends and receives email through Amazon SES in your own AWS account. That keeps sending cheap ($0.10 per 1,000 emails), and your domain's reputation stays yours, not shared with anyone else.” — the maker, Sep 2026 ↗
