For addresses only show emails from your team
No need to prefetch open_events because we just need the count which is cached
Take advantage of the counter cache on delivery_link
Use friendly urls for referring to addresses

Apart from making the urls easier to read and not needlessly refer
to an id they also avoid a possible information leak with teams where
a person could guess ids and find out email addresses that have been
used in other emails.
Even guessing email addresses avoid information leak
