n character added in html emails

An HTML editor still needs some non-printing characters, like newlines and tabs to know how to format your HTML when your editing it. But personally, I don't think that's where the problem was originating.

I'd look instead at the config settings you gave us in your original post, where you appeared (unintentionally I'm sure) to be telling CI that you wanted emails to go in HTML format but with ascii newline chars rather than HTML br tags.
