You can change which notifications you receive and on which channel for your own account only by going to Account Settings, then My Settings and selecting the Notifications tab. There you can adjust the Email delivery card to choose how frequently email-enabled notifications are sent, including options for Immediately, Daily summary, Weekly summary, or Off. Individual notification topics appear in collapsible sections with toggles for Email, Push, and Inbox, where you can enable or disable each channel per topic or whole sections and save your preferences.
However, some notifications are tagged as Required and their settings are locked and cannot be turned off for compliance reasons. Also, certain notification topics are only sent to the in-app inbox and cannot be switched off from other channels. Even when you disable email and push for a notification, it may still appear in your in-app inbox because the inbox channel is managed separately.
Because notification topics and their channels come from the server, the list you see may vary. Your preference changes apply only to your own account, and any signed-in user can access and adjust these settings. Topics you trigger yourself usually do not notify you, but colleagues with eligible roles do receive them.
