If found http://www.cannedemails.com on Hacker News. I like the idea of this website. But it’s not productive, yet.
It would be better if the body for each email would be set with JavaScript and the new lines with “%0A” instead of the indented HTML code. The indented HTML code has also effect of the style of the email: the first line is normal, the second line and all following lines are indented with 25 spaces. This looks strange.
The ask a question dialogue is wrong in the basic approach. You never should ask to ask a question. And you also shouldn’t announce your question with I just wanted to ask you a quick question. Just ask.
