Letter Opener Pro overview

Letter Opener extracts attachments from winmail.dat files (was OMiC). When using Apple Mail, if you've ever received an e-mail that included an attachment called winmail.dat, you know the frustration of not knowing what was sent to you. When this comes from an employer or client, it's even more frustrating. That winmail.dat file may only be the rich text format or it could contain an important graphic, calendar entry or invitation, task, address book contact, Microsoft Outlook Note, or nested messages. In those cases, you may miss important communications.

With Letter Opener in Apple Mail, the worry is gone. Letter Opener converts winmail.dat files on the fly, so you can actually see and use what the sender intended you to have. There's no fuss with Letter Opener, no need to drag the winmail.dat file onto another application or call upon several programs to help you. Once Letter Opener is installed, email attachments just work!

The published price is that of an annual subscription. View full pricing info.

US$20 just for an upgrade from v8 to v9 just so it works under Sierra? Bit much, my dear, unless there are some major new features that are neither mentioned here nor on the Creative in Austria website.

I previously posted this review on CNET: I've been a long time user of Letter Opener, going back to the OMiC days. Until recently, I'd not upgraded to the new version when I updated my OS to Mavericks. I thought I'd wait and see if I missed it. Lo and behold I was sorting email and came across a winmail.dat file attachment! Installing the trial, it was immediately resolved! I came to the product as a switcher from the Windows environment in 2008. I appreciate the long term development of this product, which results in fast updates when they're required by new version of Mail.app. (Wish Apple would just build it into Mail.app! But it keeps the developers of Letter Opener, Creative in Austria, in business!) At one time there was a lifetime upgrade option for this product, but I don't see it as an option, though, if you have a previous license you qualify for a reduced upgrade price (1/2 off). I hope they bring that option back. Otherwise, this product can seem costly, which I know frustrates a lot of people. All I can say, is I recommend the complainers develop a freeware tool if that's how they feel. Speaking of which, there ARE alternatives, but nothing that I've come across that integrates so seamlessly. The reality is if you don't want to pay, you don't have to. You can utilize one of the manual alternatives. Just search "winmail.dat viewer mac" and you'll come up with a handful of tools. But if you want a product that is consistently updated, integrated into Mail.app, and just works, then you'll be well served by Letter Opener. Also, kudos to Creative in Austria for taking up development of DockStar, a great tool that adds up to 5 new customizable mail indicators to the dock icon. I'd been a previous user and was sorry to see Ecamm drop the product. Happy to see it back and look forward to it moving out of BETA.

Hi! Love the plugin. Support does not seem to respond to emails tho. I wrote an email about when we can expect a version working with the new OS X 10.9.4 public beta update. It broke the plugin. Otherwise, Thumbs up.

I don' know why it just open some of my winmail files. There are totally 13 winmail.dat attachmens on my Mac Mavericks and 4 of them are fail to read. So I search and download another one - Winamil Viewer from Mac App Store. It helped me open all my cryptic winmail files. Your letter opener let me down.

Good product, absolutely NO support. Tried to e-mail them about 12 times about a billing issue, and got STRICTLY NO answer. Not even a comment saying they couldn't help. I think a good software developer/publisher should not only write good apps, but should answer his mail too, and try to help (paying!) customers. No kudos.

The function Letter Opener offers is a nice one, but the price tag is questionable from my view. I owned LO as it was beta and called OMiC to some version of LO later (10 licenses or so...). However, to pay upgrade fees for every adaptation was expensive. I understand the viewpoint of the developer (see his comments to other users below) and I appreciate that he offers lifetime licenses now (it wasn't available when I dropped LO in the past as far as I remember). Anyway, whether or not LO is worth its price is something every user has to decide him/herself. Just be aware there are alternatives (as mentioned in the "Similar Software" area above and some comments below) and even some email clients with a built in functionality similar to LO. I for example have switched to MailMate two and a half years ago. MailMate did have a price of $ 25 until lately but now $ 50 for different reasons (you may read about it on its developer page) and offers so much more functionality as LO and Mail.app together.

Just did an upgrade to 10.9.0 and promptly installed 6.0.1 of letter opener. Mail keeps on hanging requiring a force quit. Removed the extension and all good. Everytime you access an email that requires Letteropener you get a duplicate of the message showing. After each force quit another one appears. Trying to move or delete the message get a hang throwing the error message to console: 28/10/2013 11:50:28.972 am Mail[1548]: CFPropertyListCreateFromXMLData(): Old-style plist parser: missing semicolon in dictionary on line 3. Parsing will be abandoned. Break on _CFPropertyListMissingSemicolon to debug.

This is a great little addition to Mac Mail and especially appreciate the lifetime upgrade license. Pay once and get every upgrade, large or small without additional fees. A great idea I wish more developers would use. And, by the way, I don't think this developer should be disparaged for charging for his software especially when it is rock solid and he is constantly updating. That takes a lot of work! I think it is well worth the money to be able to open windat files without effort.

I purchased Letter Opener Pro on September 12. OSX Mavericks was announced in June, and expected to be available in October. In September, Mavericks was available to developers so that you could do the necessary changes. Do you really want me to pay a new upgrade now, just 5 weeks after i purchased the license? Any other serious software company would offer a free upgrade path to the version of the currently announced products

Great program - purchased in early Sept. '13 - but just installed Mavericks and it says that LO is not compatible. I purchased the option for free upgrades but I am unsure how to access the free upgrade. It does not seem to be automatic. I just downloaded v6.0 but it looks like I only have a 15 day trial. Anyone have an idea of how I can use my free upgrade option?

I've been using this software for quite some time but I'm tired of having to pay large amounts of money for each upgrade. Specifically I think this isn't worth the $ 14.95 because the developer didn't even have to spend money to acquire the OS update.

I've spent an amazingly large amount of money on this product. It is by far the lowest value I have ever received from a software product. Shame on Apple for not including a decoder in their product. But this high priced, simple program never updates and there are free alternatives. Greedware. Beware.

I purchased a previous version but it no longer works with the latest Apple Mail ap. It worked pretty well but do not wish to pay for what I consider should be a normal update. Moreover, there is no uninstaller for letter opener.

TNEFs Enough is free. It takes an extra step but $29.95 is outrageous for something you can do for free.
