Check missing mail in Gmail's Spam folder

Missing some mail sent to your Gmail account? Don't forget to look in Gmail's Spam folder. Gmail is more aggressive than many free web email providers in sending incoming email into the Spam folder. And unless you check the folder periodically, you won't know what you didn't see.
To see the Spam folder, click the More link in the left-hand navigation tree. Then click Spam. Click the check box next to messages that aren't spam and then click the Not Spam button.
