No, this is not possible …. but what you want is the emailing to the members/mods of your site if someone has changed/edited a page (or posted a comment).
This is called "watching" and is a combination of site/category/page settings (start watching site/category or page) and the personal settings of every member in his/her "activity" screen of the account !
… to get an email with the notification of the changed page..
I get an email if someone changed/create a page ( or post an comment) on my http://handbook.wikidot.com/
Go to your https://www.wikidot.com/account/activity#/watching and read the settings to get an email for such changes!
For such question it would be better to post it on the Community forum: http://community.wikidot.com/
