Inbox categories, custom fields, rules, assignment settings, response targets, snoozes, and reminders help organize queues. Staff can select published Knowledge articles and review suggested replies with source references, then edit drafts before sending; AI generation uses the workspace's configured AI provider. Shared Inbox is available on Pro, Team, and Enterprise. Listed integrations include two-way Gmail or Outlook email sync, Google or Microsoft Calendar sync, and a REST API.
