📖What it means

The composed answer to: can Meta actually deliver a message to this person RIGHT NOW — and if not, what releases it. States: open, closed, never-wrote, unreadable, no-number, and email (which has no window). Composed ONCE and attached at ANALYSIS to every resolved target, verified or refused, so the asker hears the verification half and the window half in the SAME reply. A surface may re-phrase the fields; deriving the verdict a second time is the duplicate defect (1126).

📖Easily confused with

[{"term": "Send receipt", "distinction": "The receipt says what HAPPENED to a send; deliverability says whether one can land now."}]

📖Also called

- reachability
