Eudora OSE is a freeware email client that enables you to control your POP3 and IMAP email accounts straight from the desktop.

The program is based on the much more popular Mozilla Thunderbird, so in case you're already familiar with this application, chances are that the accommodation period goes like breeze.

The interface is similar and everything seems to be just in the place you would expect them to be, with well organized menus that provide access to different sides of the app.

You can thus configure a new account, change options, compose a new mail, import settings or edit the address book entries straight from the main window.

Eudora OSE offers indexed searching, which means your search results should be displayed in no time, but also dedicated filters to better organize your inbox. Just like in Thunderbird's case, the toolbar and the buttons are fully customizable.

Composing new emails is of course easy as pie and Eudora OSE lets you edit the text, insert attachments, check the spelling, add images, tables, links, HTML content, symbols and all the usual things found in an email client.

You can configure Eudora OSE to check for new emails automatically at a user-defined interval and display a small popup notification every time a new message lands on your computer. Plus, the program works with multiple accounts at the same time, with specific rules for each of them, but also with newsgroups and feeds.

Last but not least, it's compatible with Mozilla Thunderbird extensions, which means you can always add new features and tools using Mozilla's add-on center.

With a minimum footprint on computer resources and working on all Windows flavors, it's pretty clear that Eudora OSE is one of the top picks in the email clients market.
