Follow up messages with notmuch and org-mode

After reading this article Follow Up on Emails with mu4e and Org Capture, I realized that I had the same problem. Since my email client is notmuch, I decided to customize it a bit. Fortunately, it works really well! Here’s the template I created for notmuch:

 (add-to-list
  'org-capture-templates
  '("mu" "Follow Up" entry
    (file+headline cnr/arc-fichero-accion "Acción")
    "* TODO Follow up with %(eval sent-message-to) on [[notmuch:id:%(eval sent-message-id)][%(eval sent-subject)]]
SCHEDULED: %(org-insert-time-stamp (org-read-date nil t \"+3d\"))
%i"))

The function includes a check to follow up only on emails whose subjects end with ":FUP:". Here's the code:

(add-hook 'message-sent-hook #'my/org-capture-sent-mail)
(defun my/org-capture-sent-mail ()
  "Automatically capture sent emails with subjects ending in :FUP:."
  (let* ((sent-message-id
          (replace-regexp-in-string
           "[<>]" "" (message-fetch-field "Message-Id")))
         (sent-message-to
          (replace-regexp-in-string " <.*>" "" (message-fetch-field "To")))
         (sent-subject (or (message-fetch-field "Subject") "No subject")))
    (when (string-suffix-p ":FUP:" sent-subject)
      (org-capture nil "mu"))))

This setup is simpler than using mu4e because the capture buffer automatically opens in the correct location.

That's all, folks!
