Spam email

What is spam email?

In most cases, the sender collects the recipients’ email addresses or matches characters mechanically to randomly send email.

Spam email includes the following:

  • Solicitation of dating/porn website
  • Advertisement of a webpage
  • Sales activities such as advertisement and promotion
  • Solicitation of illegal software, financial-related applications such as investment and loan
  • Chain mail for spreading misinformation
  • Email to make your computer get infected with virus
  • Email to steal your personal information
  • Scam email

Email aimed to infect with viruses, steal personal information, and perform scam are especially increasing, and damage due to these types of spam is critical. This damage may even expand if you respond to spam email.

There are a lot of spam emails which fake the recipient or sender

Spam email faking the recipient’s address (To:)

  • “I received an email addressed to another person.”
  • “I am informed that someone has received an email addressed to me.”

These are spam emails faking the recipient (To:).

Email has a function called Carbon Copy (CC) which sends a copy, and Black Carbon Copy (BCC) which masks the recipient’s address. The recipient’s address will not be shown in the address field (To:) if this BCC function is used.

If the recipient’s address is not your address, and the content is a direct email (DM), the email is sent using BCC. It is not sent to you mistakenly.

Spam email faking the sender (From:)

  • “The sender’s address (From:) of the email I received is my own email address.”
  • “Someone received a spam email which was sent from my email address.”

These are faking the sender (From:).

These emails may be sent from a third person who impersonates you.
The best way is to ignore this type of spam email. Do not access the address (URL) written in the email nor reply to it. Make sure to delete it. If you frequently receive this type of spam email, use a service such as Spam Filtering Service and set your filters/blocked addresses.
