I don't know about any other problems, but it looks like you're defining
WriteEmail to take two arguments, but you're only calling it with one  --
'%s\n' % data[0][1]  (the inner parens are unnecessary) resolves into a
single string.

I don't know that this has anything to do with unicode.  It's not terribly
clear to me just what your problem is, but at a guess... are you trying to
create a file in under Unix, that uses DOS-style line-endings (CRLF vs CR)

If that is the case, you could try doing something like

CRLF = chr(10) + chr(13)

and then concatenate CRLF into your strings wherever you'd otherwise use
\n -- '%s%s' % (data[0][1], CRLF) for example.  You'll also need to write
to your file in binary mode, of course.

If I'm mistaken about what you're trying to do, please feel free to
