## FAQ

### Is Reloop an open-source AgentMail alternative?

Yes. Reloop is Apache 2.0 and includes agent inboxes with threads, replies, IMAP and an MCP server. You can use Reloop Cloud or self-host it with no inbox limits.

### Can I get an inbox without owning a domain?

On AgentMail, yes: inboxes default to an @agentmail.to address. Reloop mailboxes live on a domain you've verified, so your agent sends as your brand.

### How many inboxes can I create?

AgentMail: 3 free, 10 on Developer ($20), 150 on Startup ($200), plus $2 per extra inbox. Reloop Cloud: 3 free, 5 on Pro ($10), 10 on Growth ($20), and unlimited when self-hosted.

### Can a human and an agent share the same inbox?

Yes, on both. Open the inbox over IMAP in any mail client while the agent uses the API or MCP server on the same threads.

### Does Reloop work with Claude, Cursor and ChatGPT?

Yes. Add https://reloop.sh/mcp as an MCP server and sign in. See the MCP server docs, or build your own agent with our guide to an AI agent that reads and replies to email.
