If you’ve been doing business in this hyper-connected world long enough, then you’ve likely encountered spam e-mails more than once. If you haven’t, you’re either ultra-protected or still painfully oblivious to e-mail.
Spam as a term doesn’t have an exact definition, since people have their own subjective interpretation of the term. In general, however, spam e-mails are those you didn’t ask for but receive, anyway. They are sent in bulk, often by senders you don’t even know. Still, there’s quite a grey area between “not spam” and “spam” territory—not all e-mails you asked for isn’t spam, and not all you didn’t ask for is spam.
