The Spam Fighters program

The Spam Fighters program helps us improve the junk mail filters in If you accept an invitation to join the program, we’ll periodically send you a copy of a message that was sent to you and ask you to vote on whether it’s spam.

After you vote, we compare your answer against those of everyone else in the Spam Fighters program. This comparison helps us improve our junk mail filters. We’ll only send you messages from your own email, so you’ll never see anyone else’s messages. 

If you select the message as junk or not junk, we may review the contents of that message. 

Here's an example of a Spam Fighters message:

Spam Fighter Message

You’ll never receive more than one message per day, and you can stop participating at any time by clicking Unsubscribe in the message.

If you're a member of the Spam Fighters program, thank you for your participation.
