Spamming is a shady form of advertising done via sending email in bulk to random email addresses gathered from publicly available sources with the intent to sell or promote something. Most spam are harmless pieces of sales literature you can safely drag to your computer’s trash bin. Some, however, may contain malicious links and come with harmful file attachments.
You may wonder how junk email was named after a brand of canned meat. Some people may consider SPAM (the canned meat) as undesirable as unsolicited email ads. But the use of the word comes from a 1970s TV skit from the iconic comedy group Monty Python. In the skit, everytime the waitress mentions “SPAM,” some Vikings start singing “SPAM! SPAM!” This drowns out all conversation in the same way spam email overloads your inbox.

When Was the First Commercial Spam Sent?
Husband and wife Laurence Canter and Martha Siegel, both lawyers, were the first to use spam to promote their immigration law services on 5 March 1994.

When Did Spamming Start Becoming a Problem?
Spam became a problem as soon as Internet usage was commercialized in the mid-1990s.

What Are the Usual Indicators That an Email Is a Malicious Spam?
Users can spot spam emails via these characteristics:
- Unfamiliar tone, which happens when a family member you’re close to suddenly sends you a formal message
- Grammar and spelling errors that occurs because most spammers don’t take time to check for them or aren’t native English speakers
- Inconsistent email address and domain name; emails from legitimate companies use the same domain name (e.g., microsoft[.]com) for email accounts and web pages

- Unusual attachments like compressed files that users don’t expect to get
- Weird requests like a bank employee asking users for their Social Security numbers when they should have these on record
- Unbelievable offers and rewards, such as winning the lottery
