Review by Joel McIntosh

A Great Tool For Opening the Occasional winmail.dat File - This app does exactly what I wanted. On rare occasions, I get a winmail.dat file attached to e-mail from a PC user. I save the attachment to my desktop, open it with this application, and boom ... I can open the attachment in the appropriate Mac application. It works great. Unlike some other reviewers, I do not want a plugin. I don't want to install a Mail bundle (and the trouble that spells every time Apple updates that is always installed on my system for the few times I encounter winmail.dat files

Does nothing of value other than telling you to buy the full version. - Pretty sure the positive reviews for this were manufactured by the software company, as this application does nothing and simply displays “buy the pro version” for it to actually do anything.

Simple solution - I’ve only needed this a handful of times, but it’s an indispensable tool for me. It’s super simple, and reliably converts emails saved in formats that my Mac can’t otherwise read. I’m a happy user.

Review by The Faj

Letter Opener is a life saver. - I had been searching forever for at least one app that would make Winmail.dat files just work on the Mac. I almost had to go back to using a Windows machine. :-O LetterOpener does the trick. If I could give it six stars I would!

Review by TSPix

Essential! - I have some clients that always send emails in this format, so it is absolutely necessary to have a reader that supports Winmail.dat. Letter Opener does a great job filling this gap on my Mac! Works flawlessly and helped me tremendously!
