Mailboxes

GET 
/mail/mailboxes

Lists integration mailboxes excluding deleted ones, newest first. api_user_id is an optional exact customer filter. total_count is the number matching the filter before pagination. Sending limits and usage are included in the same response.

Sending limits are independent of storage: 1000 recipients in the last 24 hours, or 5000 with outbound_high_limit=true; 30 messages in the last 60 seconds; 50 recipients per message across To/Cc/Bcc. SMTP and API share the counters. Usage counts accepted sending attempts, not confirmed delivery. remaining=max(0, limit-used). If usage cannot be read, the request returns 503 rather than zero usage.
