3. Advertising makes up 36% of all world spam content.


The most common spam emails are advertising messages. Want to buy new clothes? How about some aftershave? In some cases, these commercials do have a purpose, and with or without spam testing, many get to your inbox. Sometimes their presence can be interpreted as disrespectful and annoying, however, as people generally don’t like to see their email databases swarmed by hundreds of email messages advertising elixirs of youth and restaurant chains.

Why is spam called spam?

Spam luncheon meat was introduced in 1937 by Hormel Foods. There are at least two stories that explain how Spam meat became synonymous with the output of junk email generators.

The first theory relies on the untrue but widely held assumption that Spam uses some sort of substitute for meat, rather than the real deal. Fake meat, fake messages – spam.

However, another theory claims the name comes from a 1970 Monty Python’s Flying Circus sketch in which a group of customers in a Spam-themed restaurant yell and sing about Spam, eventually drowning out all other conversations – just as unfiltered spam could drown out all the legitimate email in your inbox.
