Example prompt: Can you pull up the attachment with ID att_abc123 from draft draft_xyz789 in inbox inbox_001 on AgentMail so I can review what file is attached before sending?

## When to prefer this

Use this endpoint when you need to inspect or retrieve a specific file that has already been attached to a draft email in an AgentMail inbox, particularly before sending the draft or to verify attachment contents. Prefer this over listing all attachments when you already know the specific attachment_id.
