Important
Release page notification is a ‘special’ type of email that is used to notify release page subscribers. The only difference between this & the regular email template is that there is an additional variable here - releasePageURL
For all practical purposes, this type of template is exactly the same as that of an email template. Thus, all the functionality remains as explained here.
