# Sellbird

> Sellbird is the outreach platform for AI agents. Your agent finds buyers and writes the emails; Sellbird runs the domains, inboxes, warmup, sending and replies, with draft approval on by default.

- Sellbird works with any client that supports remote MCP with OAuth sign-in, such as Claude, Claude Code, ChatGPT, Codex and Cursor. Copy the MCP address from the Agents page in your account and add it to your client. Support depends on the client’s version, plan and admin settings.
- Every campaign email waits for your approval by default. A workspace owner can turn on autopilot in settings, and then campaign emails send without one-by-one approval, still inside your sending limits and opt-out rules. Reply drafts always need your approval. Your agent can never turn on autopilot, approve a draft or approve a purchase.
- Sellbird has no AI of its own and doesn’t charge for it. Your agent runs on the AI plan or API you already pay for.
- Sellbird has no AI of its own. The customer connects their own agent (Claude Code, Codex, claude.ai, ChatGPT or another compatible MCP client) over MCP; the agent researches, writes and replies.
- Hosted Sellbird manages Google Workspace and Microsoft 365 outreach, the send schedule, reply collection and reporting.
- Every email waits in the Outbox for approval by default. Purchases and anything that raises the bill need a person to click; an agent cannot approve them.
- Replies are sorted by rule: out-of-office replies do not stop a sequence, unsubscribe requests always stop all email to that address, and a reply from anyone at a company stops the sequence for everyone there.
- Every cold email carries a one-click unsubscribe header (RFC 8058), the opt-out footer and the sender's postal address.
- Hosted Sellbird is in early access: request a spot at https://sellbird.ai/early-access/. Pricing is shared with early-access users before anything is charged.
- The open-source version is free to self-host and runs on the user's own computer with their own accounts.
