Saving Notification Settings
At the bottom of My Email Notifications, there are three buttons: Subscribe All, Apply, and Unsubscribe All.
Click Subscribe All to opt-in to all of the notifications. The radio buttons will all turn to Yes and you'll receive a popup stating that you've successfully subscribed.
Instead of clicking Subscribe All, you can choose the specific notifications that you'd like to opt-in. Click the Yes or No radio buttons next to each notification to set your preferences. Then click the Apply button. You'll receive a popup stating you successfully updated your notification preferences.
To opt-out of all notifications, click the Unsubscribe All button. The radio buttons will all turn to No and you'll receive a popup stating that you've successfully unsubscribed.
