Not everyone loves Apple’s default OS X Mail client. For those folks, Thunderbird is Mozilla’s free, and open source (if that makes you happy), Mac, *nix and Windows compatible e-mail and news client. And, it’s pretty good at creating HTML emails.

Mozilla is now shipping Thunderbird 7 (release notes), one of the products in the open source company’s rapid release program. Whereas the just released Firefox 7 has big changes under the hood, the latest Thunderbird release (whole number and all) doesn’t bring much new:

• Thunderbird is based on the new Mozilla Gecko 7 engine
• Several user interface fixes and improvements
• Several fixes to attachment handling
• Ability to print a summary of selected email messages
• Platform improvements to Address Book
• Fixed several security issues
• Numerous platform fixes that improve speed, performance and stability

That said, if you need to author HTML emails, Thunderbird is great for that.
