I think code like this would also work:

#+BEGIN_SRC emacs-lisp
(let* ((url "
https://mail.google.com/mail?view=cm&fs=1&to=duncanxyz@indeedemail.com")
       (struct (url-generic-parse-url url))
       (filename (url-filename struct)))

  (cadr (assoc "to" (url-parse-query-string filename))))
#+END_SRC
