Email notifications allows users who have provided an email address to receive email notifications when their user talk page is changed.
Can I turn this off?
Yes, this can be turned off in your preferences.
Can I get notifications for other pages?
Will I get emails for every edit?
No - once you get a notification for a page you will not receive another until you have visited the page. Naturally, you will not be notified for edits you make yourself.
Also, if you don't select the option in your preferences you will not receive notifications for minor edits.
Can I customize the email's appearance?
