"Very well implemented..."
This review was originally posted on VersionTracker.com.
A surprisingly useful little app. It's easy to assume that a web browser is the best way of accessing a web-based mail service, but MailPlane adds a lot of extra functionality and is a whole lot easier than trying to manage a gmail account via Mail.app.
I wasn't entirely sure MailPlane was for me when I first started using it, but now I find that I miss the extra functionality whenever I'm reduced to accessing GMail via Safari.
A great little app for the Gmail power user. Maybe just a tad on the expensive side, but useful enough to warrant it, imho.
