Email infrastructure for AI agents: send, read replies as threads, reply in context
SendRaven is email infrastructure for AI agents. Your agent sends an email, and when the person answers, the reply comes back as structured state: threaded on Message-ID, quoted history stripped, flagged as awaiting a reply, with the sender's authentication stated. The agent answers in the same thread, and a webhook wakes it when something new arrives. Because an autonomous sender is a different risk from a backend, limits live on the API key: a daily cap, a recipient allowlist, and a hold that turns every send into a draft for a person to approve. Works over REST or MCP (Claude, Cursor, ChatGPT and any MCP client). Priced per email sent, never per contact; 3,000 emails a month free.
