www.gmail.com, the most popular email system

Why www.gmail.com?

www.gmail.com, or google mail, is one of the most powerful email system in the world. There are ten advantages for gmail system, and which are most popular is the anti-spam.
Spam Spam Spam
I've used practically every e-mail service on the Web and I can say, without a doubt, that www.gmail.com blocks the most spam. and according to my friends' ideas, there should be a very good spam protection if you want to use a mail service, that means you should get very minimal or no spams in your inbox. So I think gmail is your option

Google Apps
Google Apps is the most functional program in the world, I can say google app is dominating the office user and business user for free app use.Maybe it's not fair to compare e-mail clients on the basis of additional apps, but I'll do it anyway. After all, we can see only google release the apps, and yahoo, microsoft and aol never launch such things.
But seems the tencent(qq.com) launch the qq.com office apps, maybe this is the only chance to beat google in the world.

Unlimited Amount of Storage
I think I don't need to explain this, right? Storage increase everyday, wow.

Gmail Filters
Gmail's filter feature is the best in the business. Period. Unlike its competitors, which try to provide a filter tool that simply re-routes incoming messages, Gmail delivers a power user's dream. In a matter of seconds, you can create a filter that searches through all incoming mail looking for specific people or keywords and once found, immediately categorizes it into a specific folder, forwards it on to someone else, or moves it to the trash, to name just a few functions.
