Why Do we need to Protect ourselves from Spam Email? 

Financial Risks

Spams can infect your computer through a Virus or Spyware.

  Here are some examples of dangerous types of spams:

  • If you’re asked to recover millions of euros in exchange for a percentage (invest abroad, chain letters, Ponzi scheme…). It is probably a scam.
  • If you receive emails from the servers indicating that you have not been able to send an email, this is called a bounce.   In this case, the spammers have stolen your identity and are sending e-mails with your name on them.
  • The spammer can also use your personal data (login details, password credit card number, etc.) to unscrupulous ends by stealing your identity. This phenomenon is called phishing.

Decline in Productivity

Spam not only steals money from business owners, but it also wastes employees’ time.

On average, a person loses 20 seconds evaluating and deleting spam messages one by one.

Wasted Storage Space  

Spam must be received by the mailbox and therefore often requires additional storage capacity. If you are concerned you can read our article on how to clear Gmail storage.
