I suggest to add in the footer the direct link to unwatch the page. 
See https://de.wikipedia.org/wiki/MediaWiki:Enotif_body where this is implemented. 

See https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/core.git;a=blob_plain;f=includes/UserMailer.php;hb=master lines 643 seq. if you want to learn which parameters can be used and how they are computed.
