Lead attachment review
“My Mermail agent mailbox received a sales lead email with an attachment att_23 in mailbox mbx_leads — can you fetch the attachment info so I know what file type it is?”

Technical details
Endpoint
GEThttps://console.mermail.app/api/agent/v1/mailboxes/%7BmailboxId%7D/attachments/%7BattachmentId%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when your AI agent needs to inspect or retrieve metadata about a specific email attachment within a Mermail-managed mailbox, particularly when processing inbound emails for sales lead nurturing, customer support workflows, or purchase-related document handling. Prefer this over generic file storage APIs when the attachment is already associated with a Mermail mailbox message.
