dead mail
LowTechnical / Formal (specific to postal services)
Definition
Meaning
Mail that cannot be delivered to the addressee or returned to the sender.
Also known as 'nixie', 'undeliverable mail' or 'dead letter'; mail that has gone through the postal system but cannot be delivered due to incorrect or insufficient address, or for which the recipient cannot be found. It is eventually sent to a central office (e.g., the Mail Recovery Center in the US) where it is opened to try to identify the sender, and contents may be auctioned or destroyed.

Dialectal Variation

Connotations
Both terms carry a bureaucratic, final, and slightly melancholic connotation of communication that has failed.
Frequency
'Dead mail' is common in US postal jargon but rare in general American conversation. 'Dead letter' is understood in both varieties but is more common in UK administrative language.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'мёртвая почта' – this is not idiomatic. Use 'недоставленная почта', 'невручённая почта', or the borrowed term 'дэд-лэттер'.
- Confusing 'dead mail' with 'junk mail' ('спам' or 'рекламная почта'). Dead mail is not spam; it's failed legitimate mail.
Common Mistakes
- Using 'dead mail' to refer to spam or unwanted mail.
- Using 'dead mail' as a general synonym for 'old mail'.
- Assuming it is a common everyday term rather than a specific technical one.
