To change your Email Notification Settings, you can click on the gear in the upper right-hand corner of your TextUs screen. This will take you to the Settings section.
From there, click on "Users." Find your name in this list, and click on the small pen icon next to it. This will allow you to edit your personal information.
The last option you will see is called "Email Forwarding." This will allow you to choose between: never, when I'm offline, or always.
After making this change, you'll want to log out of your account and then back in, to refresh the settings and put this change into action.
