Keeps Filtering Even When Your Email Program is Closed
Cloudmark DesktopOne works independently of your email program to block spam around the clock, even when your email program is closed.
Manage Multiple Email Accounts in One Window
When you’re in Pro Mode, the Accounts window displays your protected email accounts, with statistics about how many spam messages were blocked for each one. Open this window to configure Cloudmark DesktopOne to filter, sort, and delete spam.
