It seems really silly that you have to CC the recipients and tell them to ignore the message and instead look for a different message from some other address... I think that's gonna be a problem. You should try to figure out another way to handle that.

I have NoScript and, when I browse, it says, "This text will be replaced" in the top bar.

It says, "Use any email program" but all screenshots are from a Mac. Would suggest a few screenshots from Windows if that is also your audience.

Good luck!
