Feedback Action Filters
Explains filters for incoming email feedback actions. Useful for blocking unwanted senders, controlling routes, and preventing unnecessary Stubber actions.
General Information
Feedback action filters allow you to completely drop incoming emails before they trigger any actions on Stubber. Filtered emails are not stored in any database and no actions are run — they are silently discarded.
This is useful when you want to ignore emails from certain senders, or emails where you are only CC'd or BCC'd.
Filters apply across all three incoming email types:
- Stub emails — emails sent directly to a stub address (e.g.
2026-06-24-STUB-ABCD@stubber.email). Only org-level filters apply here. - Mailbox emails — emails arriving on a Stubber Email Mailbox. Org-level and mailbox-level filters apply.
- Profile emails — emails arriving on an Email Profile. Org-level and profile-level filters apply.
Filters can be configured at up to two levels:
- Org level — applies to all incoming emails across the entire organisation, regardless of how they arrive.
- Mailbox / Profile level — applies only to emails arriving on that specific mailbox or profile.
Org-level filters are always evaluated first. If an email is not dropped at the org level, mailbox or profile filters are then evaluated. An email only needs to match one filter at any level to be dropped.
Configuring Filters
All filter levels share the same configuration options. The edit panel looks like this:
Org Level
Org-level filters apply to all incoming emails across your organisation. To configure them, navigate to your organisation settings in Manage and open the Feedback Action Filters panel under email settings.
Mailbox Level
Mailbox-level filters apply only to emails arriving on a specific mailbox. To configure them, navigate to your mailbox in Manage and open the Feedback Action Filters panel.
Profile Level
Profile-level filters work the same way as mailbox-level filters. Navigate to your email profile in Manage and open the Feedback Action Filters panel.
