## Notes for agents

- A workspace can be provisioned without a human account: POST https://mcpmailer.com/v1/signup
  returns a key and a claim URL for a person to take ownership later.
- Free needs no card. Sending starts once the workspace email is verified.
- Replies to a thread someone else started are not counted against cold-send limits.
