Cloudmark Desktop (formerly SafetyBar) consists of over a million email users, all sending feedback to Cloudmark about which messages are spam or phishing and which ones are legitimate. This information helps everyone in the network. When a user clicks the Block Spam or Block Phish buttons, Cloudmark compares this feedback with feedback from other users. If other users in the network also consider the message to be spam or fraud, then similar messages are automatically blocked in the future, for all users in the network.
