Leaving and returning to the OS X email app
Postbox, Airmail 2, Outlook and of course Gmail: those are just the email apps and services I've tried this year. Any of them could've become my regular email software, but they haven't: I'm using Apple Mail, and it always seems to go this way: I try something, I come back.
Powerful replacement for Apple's Email
It used to be that free trumped everything, especially when that free was something built by Apple or Microsoft. When literally every Mac or Windows user has a particular type of software provided right there with their computer, it used to be that rivals simply died. Now we seem more open to persuasion, or at least to considering alternatives, and for some people Postbox 4 is going to be so ideal they'll wish they bought it two versions ago.
New features emphasize efficiency, management
Postbox ($40), an alternative e-mail client for Mac and Windows, has reached version 2.0 and sports a variety of new and improved features to increase users' productivity. The Mozilla-based client differentiates itself from Apple's Mail by offering support for add-ons, anti-phishing and malware protection, different views for smaller screens, tabs, built-in archiving and complex searching among other features.
