Letter Opener for Windows delivers a powerful Winmail.dat Viewer in an easy-to-use, modern app.

Some people still use Outlook. And whenever they send you something like an attachment, it shows up in your Mail with a winmail.dat file attached. (Ugh.)

But Letter Opener seamlessly converts all types of Outlook’s irksome winmail.dat files. (Hooray!)

Made with a special 😤 for winmail.dat files.
