By default, users receive regular emails with new posts and the like from sites they're a member of, based on the permissions their account has for that site. If you would rather not receive this email, you can deactivate it like so:
- Click your Username at the top right of the Guild Launch site you're logged into.
- Click the Communications tab.
- Click Email Notifications.
- Toggle the Guild Activity Update notification from Yes to No for your guild.
- Click Save Site Specific Settings.
