opensend.cc is an open source email platform that runs on your own server. It sends through your AWS account, so your domain, your data, and your sender reputation stay under your control. You get a REST API and SDK, SMTP, templates, broadcasts, automations, audiences, webhooks, and logs. Installation takes one command, and there is no per-email pricing or feature gating. If you are already on Resend, just change two lines and keep your code.
