What does inbound mean?
Inbound describes movement, communication, or delivery coming toward a particular place or destination. An inbound flight approaches an airport; inbound traffic enters a network or road system; and an inbound email arrives from someone outside the recipient's organization. The word is particularly common in aviation, transport, logistics, business, and customer-support settings, where it clearly contrasts with “outbound.” Although it can describe anything arriving from outside, it is not usually needed for personal or informal communication, where “incoming” is often more natural. “Inbound” conveys a technical or organizational perspective, focusing on the direction of travel or the source of a message relative to a central destination.
adjectiveDirected or moving toward a destination, especially toward the speaker, an organization, or a central location from outside. In business and communications contexts, it describes something received or arriving from outside.

Etymology of inbound
“Inbound” was formed in the 19th century from the prefix “in-” and “bound,” the latter deriving from Old English “boundan,” meaning “to bind.” The same Germanic root appears in “bound,” “unbound,” “rebound,” and “outbound,” although “bound” in the sense of “going toward” ultimately comes from Old Norse “bunda,” meaning “to prepare for departure.” Modern usage developed from the earlier sense of a ship or traveller heading toward a port or destination.
How inbound is actually used
