I'm trying to find a way of emailing the editor of a webpage 6 months after it has been updated so they can check the information is still up to date. I've been reading through some of the existing posts on this subject such as Send email after content update but I wanted to find out if I was going along the right lines. I have Rules and Rules Scheduler installed. Do I need an email field on the content type or can it detect the email address from the editoral workflow. I also have the Content Moderation Notifications module installed, would this module be required for this purpose?
