Undeliverable

Describing something, typically mail, an email, or a package, that cannot be successfully delivered to its intended recipient. This failure to deliver is usually due to an incorrect address, an inactive email account, the recipient's unavailability, or an issue with the delivery service itself. It signifies a breakdown in the communication or distribution process, rendering the item unable to reach its destination. The term can also be applied figuratively to describe an idea or message that is poorly conveyed or unable to find an audience.
