A "mail bomb" is a form of cyber attack where the attacker sends a massive number of emails to overwhelm the recipient's inbox and sabotage their communication systems. However, the term "mail bomb" can be confusing and misleading as it may sometimes refer to physical parcels containing explosive devices. To avoid confusion and make communication clearer, there are several synonyms for the term. Some suitable synonyms include email spamming, mail flooding, and email saturation. These synonyms accurately describe the intent and impact of the cyber attack and help to avoid any misconceptions that the term "mail bomb" may communicate.
