It shouldn't be a red (“Red50“ or destructive) button. If this is such a problem, a notice above (better) or a warning dialog (not so good, as it might cover important other UI) should be considered. A destructive flagged button should only be used in contexts where removing data/data loss is happening.
Generally, I usually notice "Blue" or "Default" as button for some action apart from delete. Yes I agree the "red" is indicates some form of removal so in this case, maybe "blue" does the trick? What about preview, maybe it can maintain the default color? So;
Send => "Blue"
Preview => "Default"
Does that make sense?
A red button is not the right approach, if necessary I'd rather put a notice message atop of the button (even though that's sounds like a bad user-interface as well form first look on).
