The default for each Guild Launch account is to receive an email when someone sends your account a private message... but to change that and make it so that you do not get emails due to private messages, you need only follow a few steps!
- Click the icon at the top right of the site, then click View PMs from the dropdown menu that appears.
- Click Email Notifications.
- Toggle the Private Message notification from Yes to No.
- Click Save Global Settings.
That's all there is to it!
