Sendoff ships self-hosted agent newsletters
Sendoff lets Claude or Codex draft, preview, test, and send newsletters and announcements through a conversational workflow. The open-source tool runs in your Cloudflare and AWS accounts, using Amazon SES for delivery and an MCP server for agent control. [GitHub repository](https://github.com/haydenbleasel/sendoff)
Sendoff makes email publishing feel like an agent task while keeping infrastructure and approval in the maker’s hands.
- –MCP support lets agents draft issues, edit Markdown, inspect analytics, and initiate sends.
- –Cloudflare Workers, D1, Queues, and Amazon SES create a self-hosted stack with direct ownership of subscriber data.
- –Live previews, test emails, preflight checks, and explicit approval add sensible safeguards before delivery.
- –The tradeoff is operational complexity: users need Cloudflare Workers Paid, AWS SES approval, DNS setup, Bun, and Git.
- –Its MIT license and `bun create sendoff` installer make it especially compelling for technical creators who want to avoid SaaS newsletter fees. [Project documentation](https://github.com/haydenbleasel/sendoff)
