Here's an explanation of all the email settings.
Option: Do you want Confluence to automatically add you as a watcher on each page or blog post that you add or update? If you are a watcher of a page or a post, you will receive notification of future changes.

Show changed content
Option: Do you want your notifications to include details of the changes made to the content?
Subscribe to recommended updates
Receive a daily or weekly email message showing the top content that is relevant to you from spaces that you have permission to view.
How do you set the frequency of the mail message? A link in the email message allows you to choose daily or weekly notifications.
How do you enable and disable the notification? You can turn off the notification by clicking a link in the email message. You can also turn the notification on or off by setting the 'Subscribe to recommended updates' option in your user profile.
Confluence chooses the content to display, based on:
'Recent' means any activity that occurred since the last recommended updates message was sent to you.
The activities are listed in order of popularity, with the most popular at the top. Likes, comments and content creations are scored equally. Activity that involves people in your network ranks higher than activity not involving your network. Content from My spaces also ranks higher than content in other spaces. The recommended updates summary does not include any content that you created yourself, and it gives a lower ranking to content that you have participated in, for example by adding a comment or updating the page.
If there is no activity to report, Confluence will not send the email message.
- Mail server: To enable Confluence to send email notifications, a System Administrator must configure an email server. See Configuring a Server for Outgoing Mail.
- Batching window: System Administrators can change the batching window for changes and comments on the same page or blog post in the Send batched notifications scheduled job. Increase the time for fewer emails or reduce the time if more immediate notifications are essential in your site.
- Recommended updates email: Confluence Administrators can set the default options for the recommended updates notification.
Select Administration , then select General Configuration. Click Recommended Updates Email in the left-hand panel. See Configuring the Recommended Updates Email Notification.
- Email threading: Confluence will attempt to group all the email notifications about changes to a specific page together. Other notifications such as sharing a page, requesting access to a page, or recommended updates emails are intentionally not grouped. Not all mail clients support email threading, and different email clients use different methods for threading emails. We've tested Confluence's email threading with Apple Mail 10.3, Outlook 2011, Outlook 2016, GMail, Google Inbox and Outlook.com.
