Was easy to install!
And is easy to use!Alexander Helbig - Germany
After months of frustration searching for a good email client for Mac, I found Postbox. Since then I've saved time, lost weight, and my hair is growing back!
Postbox is a great client for managing multiple mailboxes, the combined inbox is fast with no slow down unlike other clients. Spam filter is also excellent, I have used many spam solutions including Microsoft Outlook and found them all lacking, Postbox detects almost all spam with few false positives and best of all applies spam detection to all inboxes. Keep up the good work, well worth the money.Morgan - United Kingdom
I have used Postbox 3 and 4. I was not crazy the icons had lost their colors in Postbox 4 as I found (as an older person) them to be quite helpful. However, I can say that the Postbox programs themselves are absolutely the best I have ever used. They meet my every need. Imagine how surprised I was when I saw what the program folks had done to Postbox 5. They brought back the colors to the icons. I immediately downloaded the latest version. An added bonus was receiving a substantial discount because I had purchased the previous version. I have used may other email programs but they do not measure up to Postbox. Thanks for all your work on this latest version of Postbox.David S. - USA
As a virtual assistant, I have clients mostly in the USA and the UK, but sometimes wherever. As most clients give me at least one email address I end up with lots of accounts, and lots of emails. And I mean lots. Looking at Postbox I can see right now I have 190 emails in their main folders; I hate to think how many in the subfolders where, thanks to Postbox's filter function, emails have been automatically distributed.
So, as you imagine, email management is crucial. Right down to having
the right signature for whichever account I am currently using, which
could be a corporate one, GMail, whatever. And for some accounts I have
multiple identities. I could be writing as my client's Personal
Assistant, or as their Project Manger and so on.
LBP - Life Before Postbox meant having multiple tabs and windows open. Some easy, via GMail, others via mail clients, others via more complex routes. And I would be constantly tabbing across to check I am up to date or to actually work. And then I have the calendar functions. In short: a lot of wasted time and crucial mail not acted upon promptly.
AP - After Postbox. One window: I have actually got a PC dedicated to it. I look up and all my mail are in one window, nicely organized. Click to read. Or select the account/identity, type and send, A couple of clicks and I have calendars too. Mail kept unread, highlighted with a topic, prioritized,
Being super busy, I have yet to really take full advantage of Postbox's features. However, those I have used have been lifesavers and has made me more efficient and productive. And it has given me kudos and wows from those clients with whom mailboxes are shared.
So, folks, if you are hesitant: what are you waiting for?
You won't regret it. Postbox is simply and by far and away the best investment I have made this year in my business.Seth - USA and UK
I was using Airmail for some time but not happy with the feature set, functionality or performance. Postbox rocks!!! Cannot understand why some of the reviews of Mac OS X mail clients consider Airmail to be anywhere near as good. It isn't even close. With just a few of the add-ons installed I am now much more productive. Thanks for such a great product.Paul Calamai - Canada
Switched to Postbox from Apple Mail and in the first 24 hours things are already 1000% better. Apple Mail kept giving me IMAP connection errors and hanging up my machine, and the moment I switched to Postbox all of my troubles went away. Now I have a clean, pure experience by a group of developers who focus on e-mail for a living, unlike Apple where their Mail program is just an afterthought on macOS. I finally have my e-mail back! Thanks so much Postbox.Ethan - Windermere, FL
Great support and very available!! Thumbs up and thanks for your effort and developpement! keep on going.Yves - Switzerland
Postbox is stable, full of features! After a bit of cleaning on my part, I managed to archive 12K mails from my inbox to a gmail folder (label).
I just wanted to thank the team for making an ace mail client at a very affordable price. I have removed all other clients and solely use Postbox!Ed - Belgium
Coming from an OS X mail app, I was looking for a decent Windows mail client for quite some time. With Postbox I can now finally do my emails again under Windows the way I always wanted.
Thank you folks. Please keep up the good work!Rainer - Karben, Germany
I have always struggled with Apple Mail and recently had to update my system to 10.11. Mail became unusable. I have hundreds of thousands of emails I need to manage and began trying several different options to Apple Mail. Postbox was the only one that manages it easily, quickly, allows me to find things relatively quick and doesn't often slow down in the process. It is by far the best option I've run into. The others were junk.Steve - Canada
I've had a previous version of Postbox for many years. I never had a problem with its use. It fulfilled my requirements and was never bothersome to use. I had no complaints against it and still don't since I installed version 4.0.8. Believe me, I've had brief affairs with other email clients while still using Postbox. I've used Mailbox and eM Client for several months exclusively but have found them simply not as convenient or easy to use as Postbox. I'm back now with the latest Postbox version and am going to save myself a lot of bother by staying with it exclusively. It simply works so well!Tom Milligan - Dublin, Ireland
I just wanted to drop by and say how much I like Postbox 4. It's features and flexibility are way ahead of Apple's Mail app - it's not even close.
I'm somewhat embarrassed to say that I've been using Postbox for a couple years and only now have discovered the functionality of the Focus Pane. In my defense, my email numbers have been fairly low until now. I'm looking forward to using the Focus Pane to better manage my growing tsunami of emails.
Also, I want to thank you for creating an email client built with flexibility in mind. After years of Apple Mail's limitations, it's nice to have an app built by people who realize that not everybody fits into the same usage model.Steve - Greenacres, Washington
No longer satisfied with Entourage (part of MS Office 2008) I considered upgrading to the new Outlook (part of MS Office 2016 for Mac), but did not like the fact that the new Outlook is only available as part of an Office 365 subscription that will cost $xx per month for ever. That adds up to a lot of dollars. I then looked at reviews of OS X Mail and came to the conclusion that this product has had too many serious bugs over the last few years to be considered.
Changing over to a new email program is not something you do every day. In my case, the amount of work involved in transferring hundreds of email addresses, groups etc. is too much work to do this with a product that is not reliable. I coordinate a group with over two hundred members, growing daily, and you would not want to lose people because your email communication is a mess.
Postbox came out really well in reviews and all feedback indicated that this was a reliable, mature, yet easy to use program.
I have now used the program for just a few days and am impressed with its many features, its reliability and its speed. Not all is perfect (I am finding that the online help does not always reflect the latest version, for instance), but the program does what is promises and it does it well.
Well done, Postbox! I would be happy to recommend this program to anyone with a Mac.Max Bahrfeldt - Australia
I have been using Outlook (Mac) for years and it always has had off and on problems. Using Postbox for two months now and it has been absolutely perfect. It does everything that Outlook did for me. plus it is free. I ended up not purchasing the new Microsoft products and just went to Postbox and some other free software for all my office needs. Good stuff, just wanted to say thanks.
I forgot it was $15 or so for Postbox, I believe. Still... way better than supporting Microsoft. Thanks.
I love your Postbox application!
I just paid for my upgrade (from 2.5). Awesome product at an awesome price, I would gladly pay $25-30.
I remember the old days of Eudora and Outlook Express and there not being a great IMAP client. Thunderbird was okay.
I have been a Macintosh user for over 20 years. And e-mail applications have been an issue with me. Microsoft Entourage was just too complex for my everyday e-mail use. Along came Apple's mail which I tried but there always seemed to be some kind of annoying behavior that would crop up. Being pleased with my Apple computer I hung onto Mail hoping Apple would get Mail to run smoothly. At last I gave up and tried Postbox about two years ago and I have been so happy since. I just upgraded to version 4 and have noticed an improvement in speed versus the older version (3.0.11). Please keep up the good work and thank you for a simple e-mail application that does what it is supposed to do.John M Breitigan - USA
After months of suffering from interminable periods of unresponsiveness with Thunderbird, it finally got to the point where I could not move the cursor without it freezing up for several minutes on end. No one seems to have an answer to this, least of all Thunderbird tech themselves.
So, I installed Postbox and, voila, no problems!
Easy installation, easy import of TBird messages (exactly the same folder and file structure), both for IMAP and POP services.
So, whatever TBird did not like in my saved messages, Postbox seems to have no problem with them.
So, if you have TBird problems, just make the switch, it seems to present no downsides at all.
Particular like - the presentation of all messages for all accounts in one place.
Love the clean interface. Everything is in the right place for me. It would be an absolute complete package for me if you could provide the ability to search for a folder/label or create a new folder/label on the fly.Rusty - Woodland Hills, CA
Postbox 4 is "Head and Shoulders" above Postbox 3. That is not to mean the Postbox 3 was a slouch. Nope. It was awesome too.
Postbox 4 is cleaner, faster and smarter. One of the best things is it SHUTS DOWN right away. I dont think that is really a feature but its still a welcomed change.
Postbox 4 is great.
A great upgrade to an already fantastic product. I've tried them all; Airmail, Apple Mail, Outlook, Unibox, (I'm a bit obsessive when it comes to email). And I keep coming back to Postbox - in my opinion it's simply the best email client out there.Jonathan - Boston
Love the new version so far, UI looks way better with the improvements, much cleaner.
The only thing is that. I'm currently have 4 accounts setup (all google apps based) and from time to time I get a pop-up message that says that can't connect and I have to retry a few times. Other than that, all awesome!
Top five features I cannot live without:
1. Full intergration with OSX Address Book
2. Complete control on contents of incoming mail
3. Follow-up action on mail (eg tags)
4. Canned responses (a great time saver)
5. Full integration with Gmail & with IMAP servers
Works perfectly so far. It's very fast and reliable. I hope they will make this product even better :)Kamilsj - Taipei
For me the best mail app ever.Dichter Jerome - Luxembourg
Talk about productivity, this app is MUST HAVE!Hariawan Bangun Safutra - Indonesia
5 stars for the new interface and the new search mode!Giorgio - Rome
I manage a lot (A. LOT.) of email addresses and need to sort a lot of mail. My problems have been finding an email client that allows me to add as many accounts from every possible service as I have, and gives me way to manage an offline filing system.
So, for me, the most useful Postbox feature is the On My Mac “account” which creates that filing system on my computer. I’ve created mine in Dropbox so I can share the filing across my home and work computers.
Plus, Postbox allows me to copy messages here and not just move them off the original server, where I might want to keep a back up, just in case.
It’s not perfect; there are occasional glitches when changes are made in both locations before a sync can happen and then I have copies of directories. But so far, this is the most flexible option I’ve run across having tested nearly all the Mac OS email clients in the past 3 years.
Wishlist: iOS app that can sync the On My Mac account through Dropbox. I would love to be able to access all the saved messages to view on the road, too.
Postbox helps me keep track of my business emails. I especially like to work with topics, wich I can assign to the individual emails.Chanel Greco - Zurich
Great app. Love the new user-interface. Progress!!! :-) Thank you team!!Paul V. - France
Postbox is the only one mailer on Mac that truly manage "power usage".
Multiple accounts, hundreds of folders are treated without any problem.
I was impressed by the quality of the Search Engine, which is quite as effective as Gmail. It was a big concern for me.
Native features (like conversations, quick filing, focus pane) are really appreciated.
All this under a simple but really quick and effective UI.
My only frustration : no feature to file messages according to their label.
Postbox is my first choice for a real professional usage of e-mails.
I am using Postbox on my Mac since version 3.0. I always found that it has increased my productivity, especially with the ability of assigning topics to my emails. The integrated search function is very powerful and it helped to find back important old email contents.
Postbox 4.0 is a major upgrade, the app looks beautiful and the new features are very elegant and useful.
Keep up your good work!
I've been using Postbox since the very beginning and I must say… it's the perfect mail app out there!
It help me organise my favourite contact and focus on what really matters. I can do things so much faster with Postbox than with any other mail app, even with Gmail itself.Javier Esquivel - Chile
I have tried almost every single mail app for Mac, (at least it seems like I have), but NOTHING comes close to Postbox. The way it handles multiple accounts from the sidebar is amazing, and that alone has stopped me from even looking further for another email application.
Without sounding like I work for the company, I am here to tell you that this app is an ABSOLUTE must have for anyone that works with multiple email accounts. The add-ons are great, but I am hoping that the new release has a better calendar integration. The current Lightning format is pretty out dated, but even without that, it still the best app on the market.
Great customer support for a PB Lifer like I am, they are always responsive to questions.
Hope this helps anyone on the fence, make the jump, you won't look back.
I have tried several Mac email packages and I am telling you that there is none I have found that can hold a candle by comparison. I recently tried the latest version of Thunderbird for kix and it was like going from a Jaguar to a 1930s Model A. Thanks Postbox for such superior innovation. As long as you continue to support and innovate, your users will surely remain appreciative and loyal.Bradley Haslett - USA
Have been using Postbox for about 18 months now, and I am very pleased with it. Having come from Thunderbird, I felt right at home, and with the added bonus of the satisfaction of knowing that I have contributed to a small software company's ability to compete in a market that has its share of 800 pound gorillas.
As an aside, the recent version 3.0.9 had introduced on my Windows 7 x64 system a small, quirky bug that didn't affect the proper functioning of the program, but did generate an odd user interface issue. The folks at Postbox tracked that down from the back-and-forth e-mail communications we had, and a couple of weeks later the new 3.0.10 version has it all sorted out. Excellent service and communication!
Recommended without hesitation...Lee Weissert - USA
I joined PostBox a couple of weeks ago now.
I started with the trial, and thought I'd give it some time before making a testimonial, although I was impressed from the start. Not only has this been great and simple to use, but when I touched base with the customer support, they were fast and remarkably helpful (I loaded my information wrong - nothing to do with them!).
I've now been using this for all my mail and it's fantastic. The app has been able to do everything I need, and when I can't find something, I know the support crew are there at the ready to help out.
Thanks PostBox!Skot - New Zealand
I just have joined the Postbox community two days ago!
After cumbersome headache with Outlook 2011 for Mac and the unfortunate end of Thunderbird support last year, it is great to know that there is a true and even better alternative to the proprietary Microsoft world.
There are still some options one would like to see implemented, but I am sure that the development pace you have been showing will include these in the future.
Keep up the good work guys and be sure that I have become a true evangelist for your solution.Hisham L. - Germany
I've been using Postbox for about three years now, since the 2.0 days. It's improved a lot since then, and I can't say enough good about it. The abilities to keep my Inbox and Action folders open in adjacent tabs, to mark messages as to-dos, to send messages directly to Evernote, to file messages and switch folders via incredibly fast keyboard shortcuts, and to add other features via third-party add-ons make Postbox a great e-mail app. I've looked into a number of different e-mail clients over the years, but nothing has the combination of speed, search, and power that Postbox does. Oh, and the ability to search through previously attached files in the compose window is pure genius and saves me a ton of time, as does the Inspector Pane. (See, I really can't say enough good about this app!) My biggest wish for Postbox is that they had an iOS app.
Keep up the good work, folks, and thanks for making it easy for us to manage our e-mail!G. Godwin - USA
You really did great job ! Last week I downloaded trial version of the program. After that I have really impressed by it. And than I purchased. Now, it is my best e-mail program in my life. Please keep up your great job ! Have a nice day...Burhan TANIS - Turkey
One of the best MAC IMAP client ever seen in my life!Krzysztof Czuszek - Poland
Congratulations to all on FINALLY coming up with a stable and useful version of Thunderbird that those of us that rely on this type of email program can sink our teeth into.
I have tried all the other pretenders as far as IMAP email and really, the other attempts out there by other companies are quite sad. You have taken a solid product that has sadly languished lately and polished it up in a thoughtful and useful way for those of us that are used to certain needs out of an email client for our work.
Congratulations, I am glad I purchased this for such a reasonable cost and count me as a user for quite a long time.
I am excited to see what is next for your company and this product!Paul P. - USA
Complete, stable and best on the market email system. Thanks guys!Milan K. - Serbia
Gmail for mac done right. I love the complete customisability of Postbox. If you are a power user you can take it to full advantage and set up gmail to work like you've always wanted it to.Pascal - Australia
We use Postbox on our workstations at http://www.onlinecapital.co.uk and it's transformed our productivity hugely... for the better (naturally!).
Our mail servers are MailEnable based and we were working with a standard Thunderbird client, but Postbox is streets ahead both in looks and features. It allows our staff to handle multiple email accounts with absolute ease and organises them in a clear way which was lacking in Thunderbird (even with add-ons which were supposed to do the job). In our opinion it is also ahead of Outlook - it's lighter, looks better and handles things the way they should be done. No negatives here.
Great work from the Postbox team, keep up the great work!Peter Leigh - UK
Before Postbox, my idea of E-mail was the same as Michael R. Elkins, creator of Mutt, when he wrote, "All mail clients suck. This one just sucks less." Thank you, Postbox, Inc! You have taken the "suck" out of E-mail.Christopher Cover - USA
Our little company works with many (12) IMAP-Accounts and we was suffering under the unbelivable slow Microsoft Outlook 2010... But then a friend recommend us alternative Software, like this Postbox.
It was like the invention of fire which leeds us from the dark-age of MS Office to the new way of (much) faster and comfortable work with Postbox. After a short test-time from one week we are all happy with it and the company choose to make Postbox to our new Mail-Software.
The price for the program is absolute fair and more than adequate, we even safe a lot of money when we compare it with the MS-Outlook.
So go on Postbox-Team, we love it!T. Sabel - Germany
Postbox is the best all-around email application for making it easy for you to connect to and organize all of your email accounts. I appreciate that it continues to handle POP when applications like Windows 8 mail no longer does. For that matter I am not even sure if Outlook 2013 will.
I love the Focus Pane, it can be a life saver at times because (for work) I receive a TON of email on a daily basis. Often I simply want to focus on one or two people in a project and the focus pane makes it easy and instantaneous to switch from view to view.
Keep up the good work!
By far the best and most effective email application and all of this at a crazy low price! Nicely done Postbox…Niely done!Patrick LeClair - Canada
PostBox is lean and super-stable. Puts the things where I always wanted they would be.
In portuguese: PostBox é enxuto e super-estável. Põe as coisas onde eu sempre quis que elas estivessem.
I'm a new user but I love Postbox Mac already, and am excited to explore it's features more. I love the layout of the window and the GUI very much. Really a breath of fresh air in Mac email apps, I can't say exactly why, but it's totally how I feel about Postbox.
Other apps I have used in the past:
Apple Mail (ugh),
Mailplane (nice until recently when GUI was 'transformed' now it's more confusing not for me any more).
Sparrow - really liked a lot, looked forward to further development, new features. Would have stayed with but now it's nullware, the developers having left Sparrow behind and joined the gorging Google...grrrrrrrrrrrrrrrrrrrTom G - United States
Postbox is amazing.
I've searched for years for a desktop client that handles multiple accounts, both Gmail and non-Gmail. None of them had everything I needed.
And it's elegant. It's efficient and streamlined. It's powerful, but doesn't overwhelm me with too many features. Yet power-user features abound, and they're not hard to find when you do need or want them.
I'm finally as productive with my email as I always knew I could be with the right email client.
Postbox is amazing.Gregg S. - US
Postbox's search alone is enough to pay for. It's far superior to the MacMail app. Being able to do complicated searches within my various mailboxes is super-awesome, and it's fast, which I really appreciate.
I also love to ability to create favorite topics including to-do, pending tasks and for my various projects and clients. Suddenly I have control of my email!Jfouts - US
Currently, Postbox seems to be the best email client for Windows. I had to change a few settings to improve the toolbar appearance and unbold read messages. Still testing, but so far, so good. Fast, good-looking, customizable, proven TB platform, fast IMAP, and two-line message list pane.Drew Wesley - United States
If you're tired of Thunderbird's endless sluggishness and outdated user interface, you definitely need to make a move to Postbox. Much cleaner UI, so much easier to use, makes integration with other services a breeze, and has made email enjoyable again.Hassan Khan - United Kingdom
New PostBox owner here, upgraded from Thunderbird. After a day or so, feeling way more productive and like I'm getting ahead of the mail curve. Conversations are handled very intelligently.... this is huge and solves my biggest TB annoyance. Interface overall is truly helpful. Responses, signatures, quick reply, compose sidebar all well thought out. Focus and Inspector panes are very nice innovations.Michael W. - USA
I'm a user-interface designer and love this app for my windows environment. I was always annoyed by the bunch of unnecessary features of the other mail clients out there. Its simple to use but can do everything I need from a mail client.
I'm not buying a lot of software but postbox is definitely worth it. Thanks.Dennis - Germany
I moved from gmail for apps to Postbox on a mac to save having multiple tabs open for each email account. Postbox is much better than mail both visually and functionally. Some nice add-on like a 'send email to Evernote' shows its keeping up with other great software. Have stopped researching other email solutions for the mac now. Happily paid for Postbox.Jim - Australia
After leaving Outlook for real Gmail integration, I tried Thunderbird first. I then tried EmailTray, eM Client and Zimbra before trying Postbox.
I'm buying two licenses of Postbox.
Overall, Postbox is a very clean, very usuable interface. Feature list is the best including Gmail and Social Network integration! And seriously, the price is practically free, but I'd pay more as this is the best email app out there!Rick Boyer - USA
I was a long time user of Thunderbird and loved it but with recent releases it became prohibitively slow. There were considerable delays in the refresh speed when going from one message to another, especially with messages having graphics. But with PostBox there is little to no delay to view the very same messages... it displays messages and also boots up much faster, at least twice as fast in my experience.
Postbox's search functionality is quite a bit better too as it is both easier to use and also faster. Getting it set up was so fast and easy as well.
The main thing I would like to see is more Thunderbird extensions ported over so they work in PostBox too. The current library of extensions is rather limited, though they do have the indespensible Lightning calendar extension, and that's a good thing. It works terrific too!
Good work PostBox. I'm planning on making a complete switch to PostBox soon. Dave M. - USA
I hate Windows Live Mail so migrated to Thunderbird. Not a great improvement, expecially after the last update which broke more than it fixed. I started searching for some simple and better. I found Postbox and after testing it for several hours I was sold. It is more than worth the $9.95 I paid for it. Thank you for a fantastic product.Don Mattingly - USA
As an avid Gmail user, no other mail client comes close to leveraging the power of Gmail use with the system integration I've come to love in the Mac OS. Everything is quick, fluid, and simple. Well done.Sky Winston - USA
Search and Organization of Messages.Postbox is very good at these and I use them a lot.
I like the flexibility in how the display of information can be easily reconfigured With multiple accounts, message filters, and calendar integration, Posbox is on my Windows PC and my MAC Laptop. Gordon Leonard - USA
I've been using Postbox since the early betas, I love Postbox it's the first application I install on a new system and wouldn't be without it. The development team is on top of this project, every few months theres an update loaded with fixes and new goodies! Checkout the website (www.postbox.com) for a full list of all the great features. Postbox team, keep up the great work and keep innovating to keep us light years ahead of other email clients.Wayne02 - Portland, Maine
Best alternative to Mail, even better than Mail I think. Looks great, works great and restores great. What more can you ask for.Harrij Mensinga - Netherlands
Postbox seems the email client I looked for since several years to substitute Eudora 7.1. Postbox is easy to handle. It supports English spell checking at an active German GUI. It also handles Cyrillic letters correctly what is not possible with Eudora.Wilfried_Ennovych - Germany
If you are a mac user then postbox is awesome. For windows users, the look is not as promised. It could have been better if the mac interface (especially the buttons) could have been replicated in windows. If you are windows user, don't upgrade thunderbird as it will not support the addons. Stay in version 13 and use the theme TT DeepDark. And if you were attracted by the looks promsed in the website, please give them some time to bring it to the windows app. Thank you.Tapas - India
Postbox is a great email client. I've stopped using Thunderbird and Sparrow on Windows and MAC and now use Postbox. There's a lot of fun to work with this program. Highly recommended.Matt - US
I'm a heavy e-mail user keeping all the mail since the day one. I keep almost 10GB of e-mail across thousands of labels/folders. Recently I've been looking for a high performance e-mail client to replace slow Thunderbird and clogged Outlook. I've moved to Postbox to discover that Postbox on Windows just flies. Amazingly this tool handles gigabytes of e-mail efficiently regardless of the platform. Happily using on low spec Windows XP machines as well as newer Windows 7 machines.Maciej Zagozda - Poland
Thunderbird was always lacking in user experience. Postbox guys have made great improvements to the interface, from small things like redesigning the folder list view or improving icons, to great new features like Evernote and Dropbox integration, functional conversation view, and the ever so much used inline reply form.Now they only have to introduce a low price for migrants, and Thunderbird users are all theirs. Leonid Shevtsov - Ukraine
Piece of cake to switch to Postbox. All my account are gmail/google apps. Being IMAP accounts I only needed to transfer account settings and passwords. (not copy messages). I have over 20 email accounts for different domains.
All I did was use MozBackup to backup settings from Thunderbird then use it to restore those settings to Postbox. Everything was right there in MozBackup - it even knew I had already installed Postbox. It couldn't have been easier.
And the pricedrop from $30 to $10 was icing on the cake. ExpressItBest - USA
Email is essential for my daily work and I consider myself to be a experienced and advanced user of email clients. I moved from Thunderbird (TB) to Postbox (PB) a couple for years ago. Also I used the recent portable versions of TB intermittently over the last few years when working on computers where I don't have a PB license for.
In short, I found that, for me, there is nothing missing from PB that is available in TB, that is essential for efficient email management, but PBs implementations are much more streamlined and especially its search features are second to none. In particular the 3.x versions of PB became very good in regards to streamlining repetitive email tasks and PB is now very stable as well.
(Using PB on Windows 7 (64 and 32 bit) with Gmail IMAP accounts - I have no association with PBs developers except as a PB user). Andre C - Australia
I was having trouble with Thunderbird being slow and unresponsive, particularly when minimized. It would take up to 30 seconds or more for Thunderbird to maximize and be able to use. I found Postbox to be a lot more responsive and also a more appealing layout and design made it my go-to mail program on the Mac.Chris B. - USA
switched from XP to W7... The only option for email was Windows Live Mail.... what a disaster... Tried Thunderbird, because I was already using Firefox to my great pleasure... I never got past the stage of importing my large email "collection"... So I started to look for something else... I tried a lot... but in the end Postbox appeared to be the final solution. Imported emails using the very useful instructions... I am using it now for a couple of weeks and it is excellent!!!Lody J. Claessen - Netherlands
It's 100% transparent. I was even able to share my mail folders with Thunderbird and Postbox. There was no conversion of any kind needed. And Postbox does things Thunderbird will never do - like let me organize my mail folders into categories - you have to see it to believe it. It's a whole new way of thinking about mail management.David K - United States
I used to use Thunderbird but there were some features that it did not have #1 I prefer to view the email to the side instead of the bottom! Also it pops open immediately upon clicking the icon. I love Postbox and will not go with anything else!!happy camper - USA
I used to be a big fan of Thunderbird, but as days passed, I figured out there are many bugs in it, like old mails show on see in new mails, late refresh and all. But Postbox is just fab. I'm loving in it. It has removed all those bugs in Thunderbird. I also recommend it to everyone, just want it to be working in the background.Praveen - India
After losing my emails for the third time I knew it was time to switch. I found Postbox and immediately fell in love...Tomagig - USA
I found Postbox to easy to set up and use. I read that Mozilla was going to end their support for for Thunderbird, service but it would continue. In Postbox I receive email from three different addresses, which is something that is not always the case with other email services. Postbox is a simple to open and use service.Northville Mike - USA
With TB development apparently slowing down, Postbox is a good alternative. It uses much of the same code base, and has a very similar user experience in many ways. One hopes that they will continue to innovate more actively, even if Mozilla stops innovating on TB. But if we don't support Postbox, that won't happen.
I switched to Postbox for the Omnifocus integration on the Mac. But Postbox integrates better than TB with the the Mac in other ways too. If you don't like mail.app but would still like a stand alone mail client, this is well worth the cost. It also integrates very well with gmail and its labels.
I do wish that more TB plug-ins were supported in Postbox. But many of the important ones, like quicktext pro, are supported. Kingsinger - USA

I needed a replacement e-mail program for Apple Mail, as it is so limited in it's abilities. Over a period of time I tried 3 different versions of Thunderbird, each one a new version, the latest being v13. As with the prior versions, this v13 was worse than ever. It would take a ridiculous amount of time getting my e-mail, and would even lock up multiple times a day.... After my failed experiments with Thunderbird, I happened across Postbox, and have been very happy with it from the start. It is fast, never locks up, and is pretty much a hassle-free replacement for Mail. There is also a Windows version which makes it an all-around winner in my book!Tim J. - United States
One of the things that kept me from migrating to Windows 7 for so long was the fact that Outlook Express would no longer be available. Old habits die hard and after almost 20 years using OE with no problems I wasn't willing to give it up for Windows Live Mail or Thunderbird, neither of which I liked after trying and I never liked Outlook. I like a simple, clean interface. The old XP machine finally need to be retired in favor of a Win 7 machine (I'll give Win 8 a year to settle down before going there) and I needed to either run OE in a virtual machine, which is not an elegant solution, or find an OE substitute that I could live with. After researching the options I decided to try Postbox.
After arranging things to my liking I've found Postbox to be as close to an OE clone as I could hope for with the added benefit of additional useful features. What I especially like is that it is highly customizable to give me the look and feel that best works for me.
I should note that I first tried the Postbox Express version and was a bit turned off by it's limitations. I then tried 3.0.7 under the 30 day trial and it's terrific. In less than a week I bought the license and it's the best ten bucks I've ever spent! Late one night I had a question about a setting that I couldn't find an answer for. I sent an email to Postbox support before going to bed and the answer I was looking for was waiting for me in the morning. Excellent support! Bruce R - USA
What I liked about Postbox vs Thunderbird:
- faster loading
- faster search
- toggled communication

I was a thunderbird user for over 5 years. Over the time got access to two gmail accounts giving me a total of three gmail accounts and thunderbird wasn't able to differentiate them as I needed. Other e-mail clients didn't provide access to google calendars, which I use a lot, therefore the addition of lightning to postbox was a real selling point.Matthew - USA
My company has just moved off of Exchange to Gmail. Plus, Google just announced that they are deprecating support for ActiveSync and Google Calendar Sync. Finally, with no CardDAV/CalDAV support and a hapless IMAP implementation, Outlook wasn't going to cut it for me any more. Tried Thunderbird, but honestly, Postbox gives you the primary features of Thunderbird -- without TB's clutter, but with many more organizational tools, 2-line message views, social hooks, and first-class support for Gmail. Couple that with Lightning, and you've got a first-class email client! (Now we just need to get the dev for Google Contacts to make his add-on available to Postbox, and you've got a complete Outlook-replacement for Google!)Andy - USA
Never got Thunderbird to import my addresses and messages properly. Have used Live Email for a while... but that is a badly designed program. I am using Postbox now for some time and it really is a treat...!! Very smooth.... never a problem.... and very, very fast...LJC - Netherlands
