You can mark or unmark emails as spam. Google also automatically identifies spam and other suspicious emails and sends them to "Spam."
As you report more spam, Gmail is better able to automatically mark similar messages as spam.
On your computer, open
Gmail
Select one or more emails
Select the
Report spam
icon as shown below
Tip
: When you click the "report spam" icon or manually move an email into your Spam folder, Google will receive a copy of the email and may analyze it to help protect our users from spam and abuse.
