Email for the company: shared and personal mailboxes, portal messages, and forms in one inbox, triaged and tied to the customer, supplier, order, or job they belong to. The agent reads each thread, drafts the reply or the action in the right app, and waits for your approval. Team conversation lives in Chat; this is the outside world coming in.
A few of the views inside Inbox.
One app owns the whole domain. These are the workflows, views, and features inside it, rather than a separate tool for each.
Every person gets their own agent; teams can share one. Sensitive actions wait for approval, and every action is logged with the data it used and the outcome.
Add a field, a stage, a rule, a view, or a workflow inside this app. It's built on the same records and permissions, as open code you can change again.
Add a "inbox" view for my team: only what's mine, due this week, with the agent's drafts on top.
