Like our SpamGuard technology, SpamGuard Plus automatically filters suspected spam to your Spam folder. But SpamGuard Plus goes one step further: It remembers everything you mark as spam, personalizing the filter for even better protection.

For example, if a spam message arrives in your inbox and you mark it "Spam," Spamguard Plus will always file messages from this sender in your Spam folder.

The more you mark messages spam, the more you train the filter — and the better it works for you.

As an added bonus, Spamguard Plus offers spam protection for those Business Email customers accessing their email via Yahoo! and another email program. When you access your Business Email via POP, by default, we won't download any spam messages to your email program. However, if you'd like to download all of your messages, we can add the word "Bulk" to any messages we suspect as spam. Learn more about this feature.

Note: SpamGuard Plus is available only to those users with Business Email addresses associated with a Yahoo! ID.
