A more thorough explanation:

Spam is a term used to describe unwanted emails that are sent to people without their permission. These emails usually contain advertisements for products or services that the recipient did not ask for. Spam is also known as unsolicited commercial email (UCE) or unsolicited bulk email (UBE).

Spam emails are sent out in large quantities and are very cheap to send. This means that spammers can send thousands of emails at once, hoping to get a response from just a few people. Unfortunately, spam is often associated with scams, fraud, and offensive messages.

For example, a person might receive an email advertising a weight loss pill that promises to help them lose 10 pounds in a week. This email is considered spam because the recipient did not ask for it and it is trying to sell them something.

To avoid spam, it is important to filter your email and avoid responding to any suspicious messages. You should also be careful about giving out your email address to websites or companies that you do not trust.
