Antispam – Definition & Meaning

In this article, we will explore the definition and meaning of antispam, its origins, associations, synonyms, antonyms, root words, and example sentences.


Antispam refers to any software or hardware designed to prevent or reduce the amount of spam that is received by a user. It can also refer to any policy or practice that is put in place to prevent or reduce spam.

The term antispam originated in the early days of the internet when spam emails became a widespread problem. The first antispam measures were simple filters that could be applied to email accounts to block or redirect spam messages.
