Have you ever feel annoyed with the overloaded emails? Having heavy headache because of so many spam mails in your inbox? Or feeling so overwhelmed with the networking pages email notifications? Gmail is introducing the new priority inbox for it's loyal users. This new filtering system helps you to sort your mails from the most important one to the less important. Cool, huh? So, how does it work?
This is pretty much how your Gmail inbox looks like after the filtering. You'll spot the important mails in the 'Importand and Unread' section. It makes life easier when you're dealing with urgent business, isn't it?
As messages come in, Gmail automatically flags some of them as important. Gmail uses a variety of signals to predict which messages are important, including the people you email most (if you email Bob a lot, a message from Bob is probably important) and which messages you open and reply to (these are likely more important than the ones you skip over). And as you use Gmail, it will get better at categorizing messages for you. -source-
Alternatively, you could always mark any important mails by yourself so you know, the next time the mail reach your mailbox, it's already in the right section!
p/s: for non-Gmail users, why not try this? I mean, get a gmail account! :P
