# Delivery Preference ### Overview Email delivery preferences centralize how the platform determines which email address is used for both notification emails and digest emails. This ensures consistent delivery behavior across all system-generated communications while preserving administrative control and auditability.
*** ### Email Preference Administrators select which email field is used for all outgoing notifications and digests, choosing from a user’s primary email address, an alternate email address when enabled at the domain level, or supported custom email fields. The selected preference can be applied only to newly created users or enforced across all existing users, depending on administrative intent. All changes generate audit log entries that capture the selected delivery email type, whether users are permitted to modify their own preference, and the administrator who made the change. Fallback behavior remains consistent. When a non-primary email field is selected but is empty for a user, emails are automatically sent to the user’s primary email address. All system digest emails follow the configured delivery preference, including summaries related to posts, rewards, network activity, AI feedback, unread chats, messages, tasks, DLP alerts, and files. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
