Sendoff
Verdict: Self-hosted newsletter tool you run from Claude or Codex: your agent drafts the issue, you preview it, and nothing goes out until you say send. It lives in your own Cloudflare and AWS accounts and sends through Amazon SES, so there is no Sendoff bill — but you do have to deploy it.
Fit Developer
Levels show who gets value from it — many tools work for both beginners and experts.
🚀 Getting started: Follow the setup at sendoff.dev (bun create sendoff) to deploy into your Cloudflare and AWS accounts, then connect Claude or Codex to the MCP URL.
✅ Good fit if you already use Claude or Codex and want to email a list from your own domain without another email SaaS.
⛔ Not for you if you want a hosted dashboard with segments, automations and no cloud setup.
