Postbox

On Windows it's just Thunderbird with a new look, but it's beautiful and that's all that matters. I love it, but it's really expensive!

Sure it is just Thunderbird with a new look but oh what a look it has. For me coming from Windows Live Mail purchasing Postbox after the 30 day trial was a no-brainer to be honest. For one reason, It's lightning fast! It only takes a few seconds to pull in all my new email messages from the 4-5 accounts I manage. With WLM or Outlook it will take several minutes, this to me justifies paying the fee for a serial key.

This is what Thunderbird should've been!

I've used Postbox on Windows and OS X and it's a killer email app on any platform. It has a wealth of keyboard commands that gets you through your email fast and efficiently. For a bit of extra cost Postbox lets you have free upgrades for life (and it's a cross platform license).

I highly recommend Postbox as the best email option.

If gmail or google apps is your primary email account, Postbox seems to behave a little more seamlessly than Mac's Mail.app. Search is a little zippier, management of offline IMAP account tends to be more reliable, and it offers assorted options missing from Mail, even with some custom plugins. Still missing some key mac-ified/cocoa interface elements, but on the whole it's been a reliable client. I still complement it with Mailplane in certain circumstances but on the whole it's worth a try.

Awesome and fast. Full of epic features.

Is is pretty great compared to Apple Mail

The free version Postbox Express is excellent in handling Gmail accounts but has certain issues with Google Apps email accounts.

Had issues with it right out of the gate. Looks promising but it's basically a version of Thunderbird with some extra stuff. I'm going to give it another go but I doubt I'll buy it if I can't find a more compelling reason.

40 dollars !!
So is there a must reason switching from Apple Mail to this?

Do not think so.

To be honest, i've seen nothing which can be done in Postbox that can't be done using Thunderbird 3 for free. It is a nice client, stable, and pretty, however both Mail.app and Thunderbird are free and perform just as well.

Nice e-mail client, what i especially like is the feature where you will see past replies on an e-mail to easily fetch older data... good thinking!

I switched from Apple Mail to Postbox a few months ago. I particularly need the ability to mark messages as "sticky" so they hang out at the top above new messages. It's my new to-do list. The search seems a bit slow, but usable, however. I'd like a better way to monitor activity too. Oh, and please connect better with Apple Address Book.

switched back to thunderbird, not worth 40$. like the postbox UI approach though

Postbox was one of my favorite mail apps when it was in beta (free). It is built on the Mozilla platform. It really makes managing your mailbox easy. It features a fast search for email message (comparable to outlook if your emails are indexed) and Images/Attachment viewers to quickly find and see images and attachments in your inbox. It has some innovative features for sending emails, such as Picasa integration and google maps locations. It looks great, with a great layout, cool attachment sidebar and gmail like "conversation" style messages. Also is great for managing contacts. There can be a minor learning curve when you start using it, but once you adjust it is great. The only real downside to it is the cost. At $40, I find the price a bit steep. When comparing to outlook and entourage, I suppose it is worth the cost.. However, when also taking into consideration free email clients, the improvements it makes just aren't worth the cost to me. While it has some great innovative features, they are too minor and too few to get me to shell out $40 for. That and I still find gmail's web client much better than any desktop application for gmail accounts.
