Email wording & the email log — Every email, in and out

Settings → Email log is the record of what actually happened: everything your workspace sent, and everything that arrived at your Email In addresses. Search by subject or address, filter to sent or received, or switch to Problems only — which is the view worth opening when somebody says they never got something. Click any row to see the message exactly as it was sent. Received mail that was dropped is logged too, with the reason. An out-of-office reply that never became a record is otherwise indistinguishable from an email that never arrived at all.
