Click on the downward-facing triangle on the top right corner of your page (next to the lock icon). This will open a drop-down menu that includes options like “Create Page”, “Activity Log”, “Log Out”, and “Help”. To open your settings, click on “Settings” in this drop-down menu.
Go to your Account Settings and select Notifications from the left pane. Now you can see the Notification Settings page: https://www.facebook.com/settings?tab=notifications§ion=Facebook&view
Select “You’ll receive: All notifications, except the ones you unsubscribe from” and click “Turn On” next to “Messages” under “You’ve unsubscribed from emails about:”. That’s all.
