Create a new email inbox. Inboxes cost $2/month. Inboxes with no API activity for 30+ days are automatically deleted. Any request using the inbox resets the inactivity timer. Returns an inbox_id in email format (e.g., myagent@agentmail.to) used for all subsequent operations. If username is omitted, a random one is generated.
