What’s the most important software application you use everyday?

For me, it’s not Facebook, Twitter, or even a web browser. In my case it’s email. I can go a day without the web but an hour without checking email would be brutal.

For that reason I make the conscious decision many months ago to switch from the default Mail application included with Mac OS X and stepped up to Postbox.

Founded by Scott MacGregor and Sherman Dickman, Postbox has been around since 2007, and was actually a finalist at TechCrunch50 back in 2008. It is, in my opinion, the definitive email application.

The key points that have me sold on Postbox are:

  • Cross-platform (Windows and Mac OS X)
  • Desktop application (offline email management is huge for me, remember as I state above, I can deal without hitting the web, plus there are times during my travels that mobile and web-based connections just don’t cut it).
  • IMAP suport (critical)

Today, the Postbox team is releasing a significant update to their email management system – version 2.5 comes just three months after an already significant update was made available to us back in March.

2.5 includes these major highlights:

  • Fast 64-bit Support for Mac OS X – On the Mac, Postbox 2.5 is now running in 64-bit mode, which translates to faster startup, snappier interface elements, and quicker message loading. Our Windows version is faster too, but it currently runs in 32-bit mode.
  • Vertical Thread Pane View – Postbox now supports a double-row Vertical Thread Pane View, which makes more efficient use of widescreen displays. (This is HUGE !!!)
  • Streamlined Message View – We’ve re-designed the Message View make messages and conversations load faster, with minimal movement and jitter as you page from message to message.
  • Improved Interface + New Mac Theme – The Postbox interface is simpler and more intuitive, plus there is a fresh new theme for the Mac designed by Benjamin De Cock, and a new icon set by Kenichi Yoshida, who does a lot of work for Panic.

Included with those improvements, there are a number of additions that are just “nice to have”

  • Replaced the Status Bar with an inline notification pop-up panel
  • Simplified “Insert Link” dialog in message compose
  • Added support for playing a sound on send. Go to Preferences | Compose | Advanced to enable sound on send. (Again, nice to have…)
