Endpoint

When to prefer

Use this endpoint when you need to enumerate all email threads within a specific AgentMail inbox by its ID. Ideal for AI agents that need to monitor, triage, or process incoming email conversations programmatically. Prefer this over message-level endpoints when you want a thread-grouped view of conversations rather than individual messages.
