It’s official. No one fights spam harder, smarter, or better than Yahoo! Mail.

Independent empirical studies done by the prestigious Fraunhofer Institute show that Yahoo! Mail is #1 in blocking malware and spam from reaching mailboxes.

We, at Yahoo! are proud about putting technology to work for our users. Under the hood, a complex system of spam filters is combing every mail coming into the system for spam signals and automatically detecting the spammers’ next steps. Every spam report counts and tells a little more about how to counteract unwanted email.

Spammers use every trick in the book to distribute millions of spam and scam emails every day – but with Yahoo! Mail, most of these messages are stopped even before they get to our users. In fact, unlike our competitors’ antispam systems, our filters flag or block greater than 99% of spam. With nearly 300 million Yahoo! Mail users worldwide, we are blocking over 120 billion spam messages every month. That’s an average of 400 blocked spam messages per Yahoo! Mail inbox per month.

And we are not the only ones who have noticed our spam-reduction efforts.

The Fraunhofer Institute, an independent research firm, found that Yahoo! Mail users saw the least amount of spam out of the five providers tested, with nearly 40% less spam than Hotmail and 55% less spam than Gmail – meaning Gmail users in the study saw more than twice as much spam as Yahoo! Mail users.

While it’s great to lead the industry with our efforts, it is just as important for us to work together to win the war against spam. As we push forward with our collaboration with anti-spam industry partners, and advance our technology efforts, we’ll continue to arm you with tools, tips and strategies to keep your inbox away from spam, phishing and online scams.

And, as always, keep reporting spam so we can make our engines work even harder to keep your inbox clean.
