As the title describes, I want to be able to create an org-capture template which allows me to specify a relative date (say, 2 days) from when an email was received and print it out. The solution below uses the current date and so does not work. The alternative would be to use the available org-capture template
%:date-timestamp or similar but that does not allow me to specify a date relative to when it was received (as far as I know). Thank you in advance for any help.
(setq org-capture-templates ("c" "Client-email" item (file+headline "~/org/NOTES.org" "Client reply queue") "- [ ] [[mu4e:msgid:%:message-id][%:fromname]] DEADLINE: %(org-insert-time-stamp (org-read-date nil t \"+2d\"))"))
