You can choose how the community contacts you by customising your notification preferences. From your profile page, go to My Account > Community Notifications and select how you want to receive updates, whether that is real-time, a daily digest or a consolidated digest. Then visit Email Preferences to choose which categories of emails you want to receive.
While you are there, check your Privacy Settings to manage what other members can see about you.
These settings let you decide how the community reaches you, so you stay informed without extra emails you do not want.
