This is a promising approach. Unfortunately I cannot make it work:
email-changed-in-buffer-p is always equal to nil, even with an EMAIL in
the buffer (which I see picked up during export).

Here is what I have. This is the code to set up the EMAIL keyword:

    (:email "EMAIL" nil (org-koma-letter--get-custom org-koma-letter-email) t)
    (:email-changed-in-buffer-p "EMAIL" nil nil t)

Do we agree there should be two entries for "EMAIL"?

Thanks,

Alan
