I know Quicksilver has a plug in for quickly sending new mail messages without opening the Mail application.
But the Quicksilver plug in doesn't work under Mountain Lion.
How do you send a new mail message from Mail using Mountain Lion similar to the Quicksilver approach using preferably free application?

Check out QuickMailer. It's similar to LaunchBar but I feel that it's easier to use. Here's a screenshot:
If you're a keyboard-junkie like me, it has shortcuts to compose mail and send mail (Compose: Ctrl + ⌥ + ⌘ + m, Send: ⇧ + ⌘ + d) to speed up the mailing process too!
It isn't free, but it's pretty cheap at 99 cents. I don't own it so I haven't tried it out, but I've heard great things about it.
Hope this helps!
