Re: Replace EMAIL keyword by some LaTeX command

But you have to be certain that this command is present.

You could use etoolbox to test it.  That brings in another dependency,
tho.

Of course.  Should it?  Up to you. . .

Here's an example that you can work on.  It's not well-tested and it
has limitations and evident from the example.  E.g. you disable it by
setting #+EMAIL: .

Hope it helps,
Rasmus

#+BEGIN_SRC Org
#+TITLE:  LaTeX test
#+AUTHOR: toto
#+EMAIL:  toto@toto.org
#+LATEX_HEADER: \usepackage{nopkg}
#+OPTIONS: with-email: t
Note that 
  1. email is inserted after other =latex_headers=
  2. with-email is ignored and only the presence of email matters.
     - You could add a check to =(plist-get options :with-email)= in
       the =(and ...)= statement below and remove the =\thanks{.}= in
       a final output filter.

#+begin_src emacs-lisp
  (defun rasmus/force-insert-email (options backend)
    "Insert EMAIL as \email{EMAIL} in the latex backend when EMAIL is present."
    (when (and (org-export-derived-backend-p backend 'latex)
               (plist-get options :email))
      (plist-put options :latex-header
                 (mapconcat 'identity 
                            (remove nil
                                    (list
                                     (plist-get options :latex-header)
                                     (format "\\email{%s}" 
                                             (plist-get options :email))))
                            "\n"))
      ;; don't insert email in \thanks{.}
      (plist-put options :with-email nil))
    options)
