Thanks for all your votes and comments on this suggestion.
We fully appreciate the frustration you must feel at Confluence lacking this feature, and completely understand the value it would provide to you.
This is something we’d ideally like to implement in the future, but it's not currently on our roadmap for the next 12 months. We’re instead focusing on bringing you a new search experience, and are investigating improvements to permissions.
For more context on this, take a read of the Community blog: A renewed approach to highly voted Server suggestions for Jira and Confluence.
Further, although it won’t suit all use cases, there is an app in our Marketplace called send email to page.
