Thanks Kyle, got it to work this way:

#+BEGIN: propview :cols ((car (s-split " " ITEM))  (s-chop-prefix "gmail:" (my/extract-email-from-link EMAIL_ADDRESS)))  :id "candidates" :match "testthis" :wrap example
| (car (s-split " " ITEM)) | (s-chop-prefix "gmail:" (my/extract-email-from-link EMAIL_ADDRESS)) |
|--------------------------+---------------------------------------------------------------------|
| "Ciara"                  | "ciaraxxxx@gmail.com"                                              |
| "Duncan"                 | "duncanxxxx@indeedemail.com"                                  |

Thanks a million!

I've never used org-collector, but quickly trying to wire up a function
to extract the email part of the text you show, I suspect some of the
trouble you're having is that the value comes in as a vector because
org-propview-collect processes it with org-babel-read.  So perhaps
something like this would get you on the right track:

  (require 'subr-x)

  (defun my/extract-email-from-link (value)
    (setq value (format "%S" value))
    (when-let ((link (and (string-match org-link-bracket-re value)
                          (org-link-unescape
                           (match-string-no-properties 1 value)))))
      (thread-last
          link
        (replace-regexp-in-string
         (rx string-start (one-or-more not-newline) "to="
             (group (one-or-more not-newline)) string-end)
         "\\1")
        (replace-regexp-in-string (rx "\\.") "."))))
