Avanan now improves how trusted senders are managed by automatically learning from end-user mailbox activity.

Traditionally, end users needed to manually trust legitimate senders through the daily quarantine digest or the end user portal. With this new capability, Avanan monitors mailbox behavior and automatically adapts trust decisions based on user actions.

When a user moves an email from their Promotions or Junk folder to the Inbox, Avanan interprets this as a signal that the sender is legitimate for that specific user and automatically adds the sender to the user’s trusted senders list. This behavior applies to users who are assigned to a policy that allows end users to trust senders. Previously, users had to manually trust senders from the quarantine digest or the end-user portal to ensure future emails were delivered directly to their inbox.

This automated workflow improves user productivity while maintaining strong security controls. Instead of requiring manual interaction, the platform learns from user behavior and adjusts enforcement on a per-user basis, ensuring legitimate emails reach the inbox faster while still allowing Avanan to inspect messages for potential threats. Customers do not need to enable this capability – once the feature is deployed to the customer portal, trusted senders will be added automatically based on user activity.

Reminder: Trusted sender logic applies only to messages categorized as spam or graymail. If Avanan detects phishing, malware, or other malicious content from a trusted sender, the email will still be blocked and not delivered to the inbox.

This feature is gradually being deployed and automatic trusting senders  should start in customer portals over the next 3 weeks.
