I always use this:

          (gnus-setup-message
              'message
            (message-mail <to-address>
                          <subject>))   ;; sets up the message buffer
          (message-goto-body)           ;; places point into the body
                                        ;; region.
          (insert "bla bla")            ;; into the body
          (message-send-and-exit)       ;; sends the mail and cleans up
