We're sending regular newsletters to our employees about new services, documents etc which appear on our Sharepoint intranet portal.
To find out how many people came to specific page from a newsletter (NOT typing url directly or clicking link sent by IM), we can add some source parameter to newsletter link - like so: localportalurl/page/?source=email&campaign=ver4
is it possible to capture those parameters and filter using them in built-in Sharepoint page visitor statistics service?
Possibly similar, but with no answer: https://sharepoint.stackexchange.com/questions/28698/can-i-get-usage-statistics-on-pages-with-url-filtering
