mail bomb
B2News Media, Security, IT/Tech (in its extended sense)
Definition
Meaning
A bomb sent through the postal system, designed to explode and cause harm when opened.
The term has been extended into computing to describe an overwhelming quantity of emails or data packets sent to a target to crash their system (a 'data mail bomb'), though this is now more commonly called an 'email bomb' or 'mailbombing'.
Linguistics
Semantic Notes
A specific subtype of 'improvised explosive device' (IED). The compound is typically hyphenated ('mail-bomb') when used as a noun modifier, but often open as a noun. The verb form 'to mail-bomb' (or 'email-bomb' in computing) exists.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. In the UK, 'post' is the default term for the postal system, making 'postal bomb' or 'letter bomb' more common in everyday speech, though 'mail bomb' is understood and used in media reports, especially influenced by international news.
Connotations
In both varieties, the term carries strong connotations of terrorism, targeted violence, and criminal intent. The computing sense is more neutral, describing a denial-of-service attack method.
Frequency
Higher frequency in American English. In British English, 'letter bomb' is the most frequent equivalent for the physical device. The computing sense is equally common in both varieties in tech contexts.

Conceptual Metaphor

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct calque like '*почтовая бомба' as it sounds unnatural. The standard Russian term is 'почтовая бомба' is understood but 'письмо-бомба' (letter-bomb) is more common for the physical device, and 'спам-атака' or 'перегрузка почты' for the computing sense.
- Do not confuse with 'spam' (спам). A mail bomb in computing is a deliberate, concentrated attack to crash a system, whereas spam is typically widespread, unwanted advertising.
Common Mistakes
- Using 'mail bomb' to refer to a large volume of junk email (spam). While related in the computing sense, 'spam' is not synonymous with a deliberate crash attack.
- Incorrectly hyphenating as 'mail-bomb' in all instances; it is often open as a noun ('a mail bomb').
- Confusing 'mail bomb' (physical/cyber attack) with 'mail merge' (office software function).

FAQ
Frequently Asked Questions
A physical mail bomb is an explosive device sent by post. In computing, a 'mail bomb' is a deliberate, massive volume of emails sent to crash a recipient's system. 'Spam' is unsolicited bulk email, usually for advertising, not primarily intended to crash a system.
As a noun, it is most commonly written as two separate words ('mail bomb'). It is often hyphenated ('mail-bomb') when used as a verb or a compound adjective before a noun (e.g., 'a mail-bomb threat').
Yes, especially in computing/cybersecurity contexts. For example, 'Hackers mail-bombed the server.' For the physical act, 'to send a mail bomb' is more common than the verb form.
This is a serious security concern. Do not touch, open, or move the suspicious package. Evacuate the immediate area and contact law enforcement or security professionals immediately. This is a standard safety procedure in many workplaces.
