New Graymail Workflow: Deliver to Inbox with a Subject Prefix

A new Graymail handling option that allows messages to be delivered to the inbox with a customizable subject prefix—helping users recognize promotional content at a glance.

Unlike spam, Graymail refers to messages users technically opted in to—like newsletters, promotional offers, or notification emails—but often don’t consider critical to their daily work. While not harmful, these emails can clutter inboxes and reduce productivity.

To help organizations manage Graymail more effectively, Avanan recently introduced workflows to move these messages into a dedicated folder. Now, we’re expanding those options.

With this new workflow, Graymail messages can be delivered directly to users’ inboxes and clearly labeled using a configurable subject prefix—such as [Promotional]—so users can quickly identify and filter them as needed.

How to enable

1. Create or edit a Threat Detection Policy.
2. Under the Graymail workflow setting, select Add [Promotional] to subject.
3. (Optional) Customize the prefix text to match your organization’s preferences.

Note: This feature is currently supported for Microsoft 365 Mail only. Support for Gmail is coming soon—stay tuned for more updates.
