I started working on a new OS X app in Jun. It's a MailChimp client running on OS X. It's almost ready for some beta testing. If you use MailChimp and use OS X, you might like Wilfred. And if you like to compose your email newsletters in Markdown, especially in your own text editor, you'll probably like it more.
Official website at wilfredapp.com. Sign up to the launch email list if you are interested in beta builds or when it's ready.
Also follow it on Twitter as @wilfredapp.
