How to make Gmail work well with Mail. Google's free Gmail offers fantastic convenience and many useful features, but it's never played well with Apple's Mail.
The crux of the conflict when using Mail as a client for Gmail is labels, Google’s alternative to traditional e-mail folders. Instead of filing messages into single folders like Mail and most other clients, Gmail essentially lets you tag e-mail messages with multiple words like you can with photos on Flickr or bookmarks at Delicious. Because you can apply as many labels as you want to a message, and Google creates an All Mail folder to collect every message in your account, working with Gmail in Mail can get clunky, and fast.
