I don't know how to do it from the agenda selection, but here's a pretty
simple way to do it in the document buffer using Babel:

#+NAME: list2csv
#+BEGIN_SRC emacs-lisp :var match="topic2"
      (mapconcat 'identity 
                 (org-map-entries 
                  '(org-entry-get (point) "EMAIL") 
                  match nil)
                 ",")
#+END_SRC

Now you can use a CALL line with a tags match as a parameter, like

#+CALL: list2csv(match="topic2")

to get

#+RESULTS: list2csv(match="topic2")
: pe...@mayer.com,k...@august.com

Yours,
